Picea pungens
Also known as : White spruce, Silver spruce
The blue spruce (Picea pungens) is an evergreen conifer with a beautiful, thick crown. It gets the "blue" name because its needles have a bluish tint, unlike other pine trees whose needles are a simpler green. This unique appearance has helped to make the blue spruce one of the world's favorite ornamental conifers, and it's especially popular in Christmas tree production. Historically, these trees have also served other ornamental purposes.

What is the best way to water my Blue spruce?
If you decide to water your Blue spruce, you will be happy to find that it is a straightforward task. One of the easiest ways to water this tree is by simply turning on your garden hose and using it to soak the soil slowly. Your garden hose is the ideal watering tool to use for mature Blue spruce trees, as large specimens may need a high volume of water during each watering. However, for smaller trees, you may get by by using a watering can or some other smaller watering tool. Also, you should try to avoid overhead watering as excessive moisture on this plant’s leaves can lead to disease, especially when the tree is young.

What should I do if I water my Blue spruce too much or too little?
At times, overwatering can be the result of poor soils. Mainly, if the soil in which your Blue spruce grows does not allow water to drain effectively, the plant will likely begin to decline. If this is the case, you should either amend the soil to improve its drainage characteristics or transplant your Blue spruce to a more favorable growing location. If you grow your Blue spruce in a pot, this can also mean you may need to repot your plant with looser soils in a container that allows for better drainage. An overwatered plant may also contract diseases, which you should try to treat immediately. For an underwatered Blue spruce, the remedy is quite simple. Begin watering more often, and soon your plant will bounce back and return to full health.
The easiest way to tell if you have overwatered your Blue spruce is to observe the plant’s foliage. Specifically, looking at the new growth will give the clearest sign of whether this plant suffers from too much moisture. An overwatered Blue spruce may produce new growth, but that new growth may be discolored or prone to easy breakage. Another sign that the soil for your Blue spruce is too moist is if you notice standing water or that water is not draining quickly in your plant’s growing area. Underwatered Blue spruce trees will also have symptoms present in the foliage. In this case, the leaves may become sparse, brown. Usually, Blue spruce can grow well with rainfulls. If you see such symptoms on your plant, you should consider if there has been too much rain recently or constantly high temperatures, which will help you to make the correct judgment.

How often should I water my Blue spruce?
A mature Blue spruce does not need much water at all. In most instances, this tree will become drought tolerant and survive off of nothing more than rainfall. At most, you’ll need to water this plant about once per week during the hottest months of the year, but during other seasons, you probably won’t need to water it at all. The exception to that rule is if you are dealing with a plant that has been newly planted. If that is the case, you should water regularly to maintain consistent soil moisture and help the roots establish themselves. With that said, the most important thing to remember when watering Blue spruce is that this species does not tolerate standing water. As such, when in doubt, you should err on the side of not watering your Blue spruce rather than risking watering it too much.

How much water does my Blue spruce need?
The height of summer is one of the few times that you’ll need to water your Blue spruce. At that time of year, it is typical to give this plant about one inch of water per week. However, that amount can change depending on how much it has rained. If it has rained one inch or more that week, you won’t need to give any water to your Blue spruce.newly planted Blue spruce will need more water during the establishment period. Typically, this amounts to watering about once every one to two weeks for the first few growing seasons.

How should I water my Blue spruce through the seasons?
The Blue spruce tree will need the most water during the summer months when the weather is the hottest. At that time, you should give this plant water about once per week in the absence of rainfall. During other times of the year, this plant will often survive with no water at all. In spring and fall, you might need to provide some water if the weather is exceptionally hot, but this is rare. Unlike many other plants, the Blue spruce does not enter full dormancy in winter, which means that it will continue growing, during the coldest months. Still, the water needs during winter will remain quite low as the cool temperatures will not cause the soil to dry out quickly..

How should I water my Blue spruce at different growth stages?
Young Blue spruce trees need significantly more water than those that are established. A newly planted tree should receive water at least weekly to ensure that the soil remains moist to facilitate root development. After the first growing season, your Blue spruce should be well-adapted to its new growing location and should need much less water. At this time, you can begin following the standard instructions for watering this species, providing supplemental water about once per week during summer when it does not rain. Beyond that, there is no other time at which you’ll need to alter your watering habits based on the growth stages of the Blue spruce tree.

What's the difference between watering Blue spruce indoors and outdoors?
It is far more common to grow the Blue spruce in an outdoor growing location. However, it is also possible to grow this plant indoors in a container. In that scenario, one gardener often raise the Blue spruce as the bonsai plant. Whether you grow this plant indoors or outdoors, you can expect its water needs to remain relatively similar. The one difference is that you may need to water an indoor Blue spruce tree a bit more. Indoor plants won’t have access to rainfall during the summer. Also, indoor areas are often much drier than outdoor growing locations, and the size of the pots limits the water-retainability, which can lead to higher water needs.

Growth Rate:Slow
During spring and summer, blue spruce develops at a slow pace, focusing energy on producing dense, needle-like foliage rather than swift height gain. This gradual speed results in its robust structure and iconic conical shape, thus permitting survival in harsh conditions. Annual light blue-gray needle production, up to 1 inch, manifests this limited speed.

Name story

Blue spruce
Having blue leaves is a very rare feature in the botanical world and this plant actually has these rare blue leaves. Its blue-green needles are represented as its most symbolic feature, so it is called blue spruce.

Common Pests & Diseases About Blue spruce

Common issues for Blue spruce based on 10 million real cases
Longhorn beetles
Longhorn beetles Longhorn beetles
Longhorn beetles
The longhorn beetle is a medium- to large-sized insect with very long antennae and strong jaws. Both its adult and larval stages gnaw on tree trunks, leaving small, round holes.
Solutions: Some longhorn beetles species are native insects, and they cause little damage. Therefore, these don't warrant control. Other longhorn beetles species are invasive pests that were recently introduced from other areas. These species can cause a great deal of damage to hardwood trees. Apply an insecticide containing imidacloprid as a soil injection or trunk injection following product instructions. This will enter into new grow and kill adults who feed on foliage. This will not help save trees that are already infested with large amounts of larvae, but it will save trees located near an infested tree. Contact an arborist for best control practices regarding infected trees. To properly control longhorn beetles, all host plants in a given area must be treated. Contact a local extension agent or state agency. Tracking the spread of longhorn beetles is a key component of their control.
Branch blight
Branch blight Branch blight
Branch blight
Branch blight can cause lignified branches to dry up entirely and die.
Solutions: Inspect trees frequently, and remove any infected branches as soon as possible. Branch blight cannot be cured, so the only treatment is to prune the tree and monitor it carefully for signs of the disease. All affected parts of the tree should be removed, since blight can survive over the winter inside the plant’s tissues. Blight can become systemic in the tree, in which case the entire plant should be removed so it does not remain a host for the pathogen and allow it to spread.
Dieback
Dieback Dieback
Dieback
There are several possible causes for dieback.
Solutions: There are a few things to try when dieback becomes apparent: Fertilize and water the plants - these two steps, along with judicious pruning, can help reduce the stress on the root system and encourage renewed vigor Have an arborist check to see if plant roots are girdling Test soil pH and adjust accordingly Remove and destroy infected twigs and branches
Fruit withering
Fruit withering Fruit withering
Fruit withering
Fungal infection or normal ripening can cause the fruit to dry out.
Solutions: There are a number of appropriate solutions to control fruit withering: Remove any fruit as soon as it shows any signs of infection. Do not compost. Use a fungicide prior to leaf bud and then as per manufacturers instructions throughout the season.
Crown gall
Crown gall Crown gall
Crown gall
Bacterial infections can cause abnormal brown or black growths on the trunk of the tree. These are also called crown galls.
Solutions: Remove infected tissue. Established trees can survive a crown gall infection, but the galls should be removed to improve the plant's appearance. Use pruning shears to remove the gall, then treat the wound with a pruning sealer. Discard pruned material by putting it in the trash or burning it to avoid infecting other plants. Sterilize the pruning shears after removing the galls. Remove the entire plant. If a small plant is infected with a serious case of crown gall, the best option is to remove the entire plant and burn it. This will prevent bacteria from spreading to other plants. Sterilize the soil. After removing infected tissue, sterilize the soil using heat. Alternatively, plant a gall-resistant plant in the same spot.
Fire ants
Fire ants Fire ants
Fire ants
Fire ants gnaw on the roots of plants and are aggressive toward people.
Solutions: Caution: fire ants are venomous and cause painful bites which can be fatal in the case of a rare but significant allergy. Fire ants can be a painful pest to have around for you and your plants. Keeping them under control will ensure comfortable gardening for all. For less severe cases: Physically remove mounds. Dig out and remove entire mounds (remember, they go deeper than they seem). Use citrus oil. Pour citrus oil, which is toxic to fire ants, down their holes. For severe cases: Use ant bait. For a chemical solution, broadcast insecticide bait formulated for fire ants in the area around a mound. Apply the bait during a dry evening so the ants can forage for it at night. Look for products that contain Indoxacarb. Release phorid flies. Introduce or promote beneficial phorid flies to gardens. These parasitic flies attack invasive fire ants. Hire a professional. Some ant baits are only available to professional exterminators. For serious cases of fire ants, consider hiring a professional.

Longhorn beetles
plant poor
Longhorn beetles
The longhorn beetle is a medium- to large-sized insect with very long antennae and strong jaws. Both its adult and larval stages gnaw on tree trunks, leaving small, round holes.
Overview
Overview
Longhorn beetles are characterized by extremely long antennae which are often as long as, or longer, than the beetle's body. Adult longhorn beetles vary in size, shape, and coloration, depending upon the species. They may be 6 to 76 mm long. The larvae are worm-like with a wrinkled, white to yellowish body and a brown head.
Longhorn beetles are active throughout the year, but adults are most active in the summer and fall. Larvae feed on wood throughout the year.
Both larvae and adults feed on woody tissue. Some of the most susceptible species include ash, birch, elm, poplar, and willow.
If left untreated, longhorn beetles can kill trees.
Symptom Analysis
Symptom Analysis
Longhorn beetles are attracted to wounded, dying, or freshly-cut hardwood trees. Adults lay their eggs in the spring, summer, and fall on the bark of greenwood. There may be sap around egg-laying sites.
Once the eggs hatch, larvae called round-headed borers burrow into the trunk to feed. They may tunnel for one to three years depending on the wood's nutritional content. As the larvae feed, they release sawdust-like frass at the base of the tree.
Eventually, the larvae turn into pupae and then adults. When the adults emerge, they leave 1 cm holes in the bark on their way out. Adults feed on leaves, bark, and shoots of trees before laying eggs.
After a few years of being fed upon by longhorn beetles, a tree will begin losing leaves. Eventually, it will die.
Solutions

Branch blight
plant poor
Branch blight
Branch blight can cause lignified branches to dry up entirely and die.
Overview
Overview
"Blight" is an umbrella term used to describe a category of tree diseases caused by fungus or bacteria. Branch blight occurs when fungus attacks the branches and twigs of a tree, resulting in branches slowly dying off.
Branch blight can affect most species of trees to some degree, and it may be called by different names including twig blight or stem blight. It is caused by a variety of fungi which attack branches first, especially immature growth.
Blight usually occurs in warm, humid conditions, so is most common in the spring and summer months. Because specific environmental conditions are required, the frequency of branch blight can vary from year to year. This makes the disease hard to control, as it can spread between trees and affect multiple plants in a short period of time.
In the worst-case scenario, trees can lose significant portions of their foliage and fail to produce fruit. Young or unhealthy trees could die off completely.
Symptom Analysis
Symptom Analysis
The first symptoms of branch blight are that the emerging foliage turns brown or gray at the tips, especially on the smallest branches. Brown spots cover the entire surface of the leaves, eventually causing leaves and stems to shrivel and fall off. Over time, the dying tissue will spread toward the center of the plant. If left untreated, spores from the attacking fungus may appear on dying foliage within 3-4 weeks of the infection.
In some cases, lesions may form at the spot where the twig branches off from the healthy tissue. Branches may display girdling, which is a band of damaged tissue encircling the branch. An untreated tree will eventually lose all of its foliage and die.
Disease Cause
Disease Cause
  • Pathogens on young twigs and foliage cause disease
  • Stressed and unhealthy trees are more susceptible - root injury due to physical or insect damage, infection, or aging can prevent adequate absorption of water and nutrients
  • Extremely wet conditions including sprinkler watering can attract fungus
  • Fungi can be transmitted between nearby trees

Dieback
plant poor
Dieback
There are several possible causes for dieback.
Overview
Overview
Dealing with dieback in plants can be tricky, in part because this is both the name of a disease itself and a common symptom of many other types of diseases. Dieback can be characterized by the progressive, gradual death of shoots, twigs, roots, and branches, generally starting first at the tips.
In many cases, dieback is caused by fungi or bacteria. These pathogens can produce cankers, wilts, stem or root rots, and even anthracnose, but the most common symptom, of course, is that various plant parts (or the entire plant) will begin to die back.
Symptom Analysis
Symptom Analysis
The symptoms of dieback can be gradual or slightly more abrupt. Usually, however, they are slow in developing and tend to be uniform among the various parts of a plant.
Some plants may have more localized symptoms, with all twigs affected or all branches affected but not the rest of the plant. Some potential symptoms include:
  • Dead or dying branches and twigs
  • Dieback that starts in the top of a plant and progresses downward (though it can start lower, especially for conifers)
  • A delayed flush of growth in the spring
  • Leaf margins become scorched
  • Pale green or yellow leaves
  • Leaves that are small or otherwise distorted
  • Early leaf drop
  • Reduced growth of twigs and stems
  • Thinning of crown foliage
  • Production of suckers on trunk and branches
  • Premature fall coloration (in tree species like birch, sweetgum, maple, oak, ash, etc)
The symptoms of dieback can occur within just one season or become worse each and every year.
Disease Cause
Disease Cause
There are several types of dieback, each of which has a different cause with which it is associated.
"dieback" as a standalone issue, including the condition known as Staghead, is caused by fungal or bacterial infections. Staghead is a slow dieback that occurs on the upper branches of a tree, named as such because the dead limbs look much like the head of a stag.
Other causes of dieback symptoms include:
  • Cankers or wilts
  • Stem or root rots
  • Nematodes
  • Stem or root boring insects
  • Pavement being placed over root systems
  • Winter injury from cold
  • Salt damage
  • Lack of moisture (or excess of moisture)
  • Lack of an essential nutrient or element
Trees and shrubs that are attacked by insects, exposed to extremely high or low temperatures, or experience severe and frequent fluctuations in soil moisture are the most likely to suffer from dieback. These stress factors alone or in combination with each other can reduce leaf and shoot growth, and progress into death of twigs and branches.
Although any of these issues can lead to dieback, the most serious consequences tend to occur when the roots of a plant are damaged. Similarly, trees and shrubs that are planted improperly or in unfavorable locations are more likely to develop this condition.

Fruit withering
plant poor
Fruit withering
Fungal infection or normal ripening can cause the fruit to dry out.
Overview
Overview
Fruit withering is common on many tree fruits, including apples, pears, peaches, cherries, and plums, as well as fruiting shrubs. It is caused by a fungal pathogen and will result in wrinkled and desiccated fruit.
Symptom Analysis
Symptom Analysis
Here are the most common symptoms in the order that they are likely to occur.
  1. Both leaves and blossom on the tips of branches will go brown and wither.
  2. Gray powdery patches will appear on infected leaves and flowers, and this will be most apparent after rain.
  3. Any fruit that does appear will turn wrinkled and fail to develop.
  4. Branch tips begin to die, progressing back to larger branches, causing general deterioration of the tree or plant.
Disease Cause
Disease Cause
The withering is caused by one of two fungal pathogens, one called Monilina laxa and the other called M. fructigen. The spores overwinter on infected plant material and are then spread the following spring by wind, rain, or animal vectors. The problem will start to become noticeable in mid-spring, but will increase in severity as summer progresses and the fungus grows. If not addressed, the disease will intensify and spread to other plants in the vicinity.

Crown gall
plant poor
Crown gall
Bacterial infections can cause abnormal brown or black growths on the trunk of the tree. These are also called crown galls.
Overview
Overview
Crown gall is a bacterial disease that affects many different species of shrubs. It produces unsightly growths called galls on stems, branches, and roots. These galls stunt the growth of plants and weaken them. This is because they disrupt the flow of water and nutrients from the roots up to other areas of the plant.
Crown gall growth is generally more rapid during warm weather. There are no chemical solutions available that will kill this disease. The presence of galls does not usually cause the death of a plant, however. These galls can easily be spread to other plants through contaminated tools or soil.
Symptom Analysis
Symptom Analysis
Crown gall is most often seen on lower branches. This disease appears as deformed growths on stems, branches, or roots that gradually enlarge over time.
As the galls enlarge, they become hard and woody. Their appearance is usually brown and corky. The plant will show symptoms of stunted growth and there may be evidence of tip dieback.
Disease Cause
Disease Cause
Crown gall is caused by the bacteria Agrobacterium tumefaciens. This bacteria lives in the soil, and can survive there for many years. It is spread onto the plant by water splashing up from contaminated soil. Infected pruning tools can also spread the disease onto plants.
The bacteria enter the plant through open wounds. These could be caused by chewing insects or damage from gardening tools such as lawnmowers. Pruning cuts that have not been treated can also be infected by this bacterial disease.
Once the bacteria have entered the plant, they stimulate rapid growth in plant cells, and this is what causes the abnormal growths.

Fire ants
Fire ants gnaw on the roots of plants and are aggressive toward people.
Overview
Overview
Fire ants are a group of ants that are known for their aggressive behavior and painful stings. Some fire ants are native and others are invasive from other countries. Once they reach plants, they climb them and chew away at leaves and flower buds.
Fire ants also kill and eat beneficial insects such as caterpillars, ladybugs, mantis, and native ants. They can be a problem any time temperatures are above freezing, but new infestations are most likely to appear when brought in via contaminated material such as potting soil or mulch, or when insecticides have harmed populations of beneficial insects that would otherwise control populations of fire ants.
They can be difficult to control, especially once populations become large. Plant damage is typically minor, but fire ants can destroy seedlings.
Symptom Analysis
Symptom Analysis
The number one symptom of fire ants is seeing the ants themselves which are red or black in color. Ant mounds in the ground are also signs. Fire ant mounds rarely exceed 46 cm in diameter. If a fire ant mound is disturbed, many fast-moving, aggressive ants will emerge. These ants will bite and then painfully sting.
Even if no ants are visible, their damage might be apparent. Chewed leaf and flower edges might indicate fire ants. Fully eaten seedlings are another sign.
Solutions
Solutions
Caution: fire ants are venomous and cause painful bites which can be fatal in the case of a rare but significant allergy.
Fire ants can be a painful pest to have around for you and your plants. Keeping them under control will ensure comfortable gardening for all.
For less severe cases:
  • Physically remove mounds. Dig out and remove entire mounds (remember, they go deeper than they seem).

More Info on Blue Spruce Growth and Care

Basic Care Guide
Explore More
Water
Every 1-2 weeks
Blue spruce is native to the harsh surroundings of the Western U.S.'s Rocky Mountains, exposed to relatively low annual precipitation. These resilient evergreens have adapted to profit from infrequent and unpredictable rainfall patterns. Their watering needs, therefore, reflect this, with the requirement for thorough watering but also appreciable durations of dryness in between. Over-watering or a lack of appropriate drainage could easily become detrimental, as they're adapted to endure periods without excess moisture.
Watering Techniques
Lighting
Full sun
The blue spruce thrives under full light exposure for optimum growth and can manage moderately lit environments well. Its origins lie in habitats where constant sun is prevalent. Overexposure can cause needle scorching, while inadequate exposure can weaken its sturdy nature and overall health.
Best Sunlight Practices
Temperature
-35 - 35 ℃
In its native growth environment, blue spruce thrives in temperatures ranging from -40 to 23 ℉ (-40 to -5 ℃). However, it can adapt to temperatures between 0 to 32 ℉ (-18 to 0 ℃) and prefers cooler temperatures. During the winter, it is important to ensure that the plant is not exposed to sudden temperature changes that can damage its roots.
Temp for Healthy Growth
Transplant
30-50 feet
The perfect time for transplanting blue spruce is from late spring to midsummer, as it allows ample time for the root system to establish before winter. Choose a sunny location with well-draining soil. For a successful transplant, ensure young trees are well-watered and protected from strong winds.
Transplant Techniques
Pruning
Winter
A majestic conifer, blue spruce is renowned for its silvery-blue needles and conical shape. Optimal pruning involves removing damaged or diseased branches and shaping the lower parts to maintain a balanced form. Best performed in winter during dormancy to minimize sap loss and prevent disease. Pruning should be conservative, as blue spruce has a slow growth rate, and over-pruning can result in sparse needle regrowth. Strategic thinning enhances air circulation and light penetration, promoting overall tree health.
Pruning techniques
Feng shui direction
North
The blue spruce is known to harmonize well with North-facing spaces. Its evergreen, coniferous attributes and deep blue tones help to reinforce the water element, thereby fostering a sense of stability, growth, and prosperity. However, individual experiences might vary, as Feng Shui lends itself to personal interpretation and adaptation.

Growth Rate:Slow
During spring and summer, blue spruce develops at a slow pace, focusing energy on producing dense, needle-like foliage rather than swift height gain. This gradual speed results in its robust structure and iconic conical shape, thus permitting survival in harsh conditions. Annual light blue-gray needle production, up to 1 inch, manifests this limited speed.

Common Pests & Diseases About Blue spruce

Common issues for Blue spruce based on 10 million real cases
Longhorn beetles
Longhorn beetles Longhorn beetles Longhorn beetles
The longhorn beetle is a medium- to large-sized insect with very long antennae and strong jaws. Both its adult and larval stages gnaw on tree trunks, leaving small, round holes.
Solutions: Some longhorn beetles species are native insects, and they cause little damage. Therefore, these don't warrant control. Other longhorn beetles species are invasive pests that were recently introduced from other areas. These species can cause a great deal of damage to hardwood trees. Apply an insecticide containing imidacloprid as a soil injection or trunk injection following product instructions. This will enter into new grow and kill adults who feed on foliage. This will not help save trees that are already infested with large amounts of larvae, but it will save trees located near an infested tree. Contact an arborist for best control practices regarding infected trees. To properly control longhorn beetles, all host plants in a given area must be treated. Contact a local extension agent or state agency. Tracking the spread of longhorn beetles is a key component of their control.

Branch blight
Branch blight Branch blight Branch blight
Branch blight can cause lignified branches to dry up entirely and die.
Solutions: Inspect trees frequently, and remove any infected branches as soon as possible. Branch blight cannot be cured, so the only treatment is to prune the tree and monitor it carefully for signs of the disease. All affected parts of the tree should be removed, since blight can survive over the winter inside the plant’s tissues. Blight can become systemic in the tree, in which case the entire plant should be removed so it does not remain a host for the pathogen and allow it to spread.

Crown gall
Crown gall Crown gall Crown gall
Bacterial infections can cause abnormal brown or black growths on the trunk of the tree. These are also called crown galls.
Solutions: Remove infected tissue. Established trees can survive a crown gall infection, but the galls should be removed to improve the plant's appearance. Use pruning shears to remove the gall, then treat the wound with a pruning sealer. Discard pruned material by putting it in the trash or burning it to avoid infecting other plants. Sterilize the pruning shears after removing the galls. Remove the entire plant. If a small plant is infected with a serious case of crown gall, the best option is to remove the entire plant and burn it. This will prevent bacteria from spreading to other plants. Sterilize the soil. After removing infected tissue, sterilize the soil using heat. Alternatively, plant a gall-resistant plant in the same spot.

Fire ants gnaw on the roots of plants and are aggressive toward people.
Solutions: Caution: fire ants are venomous and cause painful bites which can be fatal in the case of a rare but significant allergy. Fire ants can be a painful pest to have around for you and your plants. Keeping them under control will ensure comfortable gardening for all. For less severe cases: Physically remove mounds. Dig out and remove entire mounds (remember, they go deeper than they seem). Use citrus oil. Pour citrus oil, which is toxic to fire ants, down their holes. For severe cases: Use ant bait. For a chemical solution, broadcast insecticide bait formulated for fire ants in the area around a mound. Apply the bait during a dry evening so the ants can forage for it at night. Look for products that contain Indoxacarb. Release phorid flies. Introduce or promote beneficial phorid flies to gardens. These parasitic flies attack invasive fire ants. Hire a professional. Some ant baits are only available to professional exterminators. For serious cases of fire ants, consider hiring a professional.

Longhorn beetles
plant poor
Longhorn beetles
The longhorn beetle is a medium- to large-sized insect with very long antennae and strong jaws. Both its adult and larval stages gnaw on tree trunks, leaving small, round holes.
Overview
Overview
Longhorn beetles are characterized by extremely long antennae which are often as long as, or longer, than the beetle's body. Adult longhorn beetles vary in size, shape, and coloration, depending upon the species. They may be 6 to 76 mm long. The larvae are worm-like with a wrinkled, white to yellowish body and a brown head.
Longhorn beetles are active throughout the year, but adults are most active in the summer and fall. Larvae feed on wood throughout the year.
Both larvae and adults feed on woody tissue. Some of the most susceptible species include ash, birch, elm, poplar, and willow.
If left untreated, longhorn beetles can kill trees.
Symptom Analysis
Symptom Analysis
Longhorn beetles are attracted to wounded, dying, or freshly-cut hardwood trees. Adults lay their eggs in the spring, summer, and fall on the bark of greenwood. There may be sap around egg-laying sites.
Once the eggs hatch, larvae called round-headed borers burrow into the trunk to feed. They may tunnel for one to three years depending on the wood's nutritional content. As the larvae feed, they release sawdust-like frass at the base of the tree.
Eventually, the larvae turn into pupae and then adults. When the adults emerge, they leave 1 cm holes in the bark on their way out. Adults feed on leaves, bark, and shoots of trees before laying eggs.
After a few years of being fed upon by longhorn beetles, a tree will begin losing leaves. Eventually, it will die.
Solutions

Prevention
  • Keeping trees healthy, uninjured, and unstressed will help prevent beetle infestation. Water trees appropriately, giving neither too much nor too little.
  • Check with local tree companies about which tree species have fewer problems.
  • Avoid moving firewood as this can introduce exotic longhorn beetles.
  • Routine spraying of persistent, broad-spectrum insecticides will help prevent re-infestation of previously affected trees or infestation of unaffected trees.

Branch blight
plant poor
Branch blight
Branch blight can cause lignified branches to dry up entirely and die.
Overview
Overview
"Blight" is an umbrella term used to describe a category of tree diseases caused by fungus or bacteria. Branch blight occurs when fungus attacks the branches and twigs of a tree, resulting in branches slowly dying off.
Branch blight can affect most species of trees to some degree, and it may be called by different names including twig blight or stem blight. It is caused by a variety of fungi which attack branches first, especially immature growth.
Blight usually occurs in warm, humid conditions, so is most common in the spring and summer months. Because specific environmental conditions are required, the frequency of branch blight can vary from year to year. This makes the disease hard to control, as it can spread between trees and affect multiple plants in a short period of time.
In the worst-case scenario, trees can lose significant portions of their foliage and fail to produce fruit. Young or unhealthy trees could die off completely.
Symptom Analysis
Symptom Analysis
The first symptoms of branch blight are that the emerging foliage turns brown or gray at the tips, especially on the smallest branches. Brown spots cover the entire surface of the leaves, eventually causing leaves and stems to shrivel and fall off. Over time, the dying tissue will spread toward the center of the plant. If left untreated, spores from the attacking fungus may appear on dying foliage within 3-4 weeks of the infection.
In some cases, lesions may form at the spot where the twig branches off from the healthy tissue. Branches may display girdling, which is a band of damaged tissue encircling the branch. An untreated tree will eventually lose all of its foliage and die.
Disease Cause
Disease Cause
  • Pathogens on young twigs and foliage cause disease
  • Stressed and unhealthy trees are more susceptible - root injury due to physical or insect damage, infection, or aging can prevent adequate absorption of water and nutrients
  • Extremely wet conditions including sprinkler watering can attract fungus
  • Fungi can be transmitted between nearby trees
Solutions
Solutions
  • Inspect trees frequently, and remove any infected branches as soon as possible. Branch blight cannot be cured, so the only treatment is to prune the tree and monitor it carefully for signs of the disease.
  • All affected parts of the tree should be removed, since blight can survive over the winter inside the plant’s tissues.
  • Blight can become systemic in the tree, in which case the entire plant should be removed so it does not remain a host for the pathogen and allow it to spread.
Prevention
Prevention
  • Avoid purchasing trees with dead or dying growth.
  • Sterilize cutting tools frequently when pruning to avoid spreading fungus between plants.
  • Keep trees mulched and watered, especially during dry periods, to prevent stress.
  • Avoid splashing water on the leaves when watering, as wet foliage is attractive to fungi and bacteria.
  • When planting, allow enough room between trees that there will be sufficient air circulation for them to dry out. Crowding trees too close together can increase humidity and allow the fungi to transfer.
  • When conditions are wet and humid, a fungicide can be used on new growth.

Dieback
plant poor
Dieback
There are several possible causes for dieback.
Overview
Overview
Dealing with dieback in plants can be tricky, in part because this is both the name of a disease itself and a common symptom of many other types of diseases. Dieback can be characterized by the progressive, gradual death of shoots, twigs, roots, and branches, generally starting first at the tips.
In many cases, dieback is caused by fungi or bacteria. These pathogens can produce cankers, wilts, stem or root rots, and even anthracnose, but the most common symptom, of course, is that various plant parts (or the entire plant) will begin to die back.
Symptom Analysis
Symptom Analysis
The symptoms of dieback can be gradual or slightly more abrupt. Usually, however, they are slow in developing and tend to be uniform among the various parts of a plant.
Some plants may have more localized symptoms, with all twigs affected or all branches affected but not the rest of the plant. Some potential symptoms include:
  • Dead or dying branches and twigs
  • Dieback that starts in the top of a plant and progresses downward (though it can start lower, especially for conifers)
  • A delayed flush of growth in the spring
  • Leaf margins become scorched
  • Pale green or yellow leaves
  • Leaves that are small or otherwise distorted
  • Early leaf drop
  • Reduced growth of twigs and stems
  • Thinning of crown foliage
  • Production of suckers on trunk and branches
  • Premature fall coloration (in tree species like birch, sweetgum, maple, oak, ash, etc)
The symptoms of dieback can occur within just one season or become worse each and every year.
Disease Cause
Disease Cause
There are several types of dieback, each of which has a different cause with which it is associated.
"dieback" as a standalone issue, including the condition known as Staghead, is caused by fungal or bacterial infections. Staghead is a slow dieback that occurs on the upper branches of a tree, named as such because the dead limbs look much like the head of a stag.
Other causes of dieback symptoms include:
  • Cankers or wilts
  • Stem or root rots
  • Nematodes
  • Stem or root boring insects
  • Pavement being placed over root systems
  • Winter injury from cold
  • Salt damage
  • Lack of moisture (or excess of moisture)
  • Lack of an essential nutrient or element
Trees and shrubs that are attacked by insects, exposed to extremely high or low temperatures, or experience severe and frequent fluctuations in soil moisture are the most likely to suffer from dieback. These stress factors alone or in combination with each other can reduce leaf and shoot growth, and progress into death of twigs and branches.
Although any of these issues can lead to dieback, the most serious consequences tend to occur when the roots of a plant are damaged. Similarly, trees and shrubs that are planted improperly or in unfavorable locations are more likely to develop this condition.
Solutions
Solutions
There are a few things to try when dieback becomes apparent:
  • Fertilize and water the plants - these two steps, along with judicious pruning, can help reduce the stress on the root system and encourage renewed vigor
  • Have an arborist check to see if plant roots are girdling
  • Test soil pH and adjust accordingly
  • Remove and destroy infected twigs and branches
Prevention
Prevention
The best way to prevent dieback is to match the plant to the site. Make sure the conditions provided for a new planting match its needs.
  • Plant properly in deep, fertile well-draining soil
  • Make sure plant roots won’t be confined when the plant reaches its mature size
  • Avoid changes to the growing site
  • If soil compaction might be an issue, apply a few inches of wood chips and eliminate traffic over the root area
  • Fertilize and water appropriately
It is also important to avoid potential infection with pathogens that can cause dieback:
  • Avoid binding or wounding the roots and trunk whenever possible
  • Avoid excessive pruning
  • Disinfect all tools before working with plants to reduce the spread of disease

Fruit withering
plant poor
Fruit withering
Fungal infection or normal ripening can cause the fruit to dry out.
Overview
Overview
Fruit withering is common on many tree fruits, including apples, pears, peaches, cherries, and plums, as well as fruiting shrubs. It is caused by a fungal pathogen and will result in wrinkled and desiccated fruit.
Symptom Analysis
Symptom Analysis
Here are the most common symptoms in the order that they are likely to occur.
  1. Both leaves and blossom on the tips of branches will go brown and wither.
  2. Gray powdery patches will appear on infected leaves and flowers, and this will be most apparent after rain.
  3. Any fruit that does appear will turn wrinkled and fail to develop.
  4. Branch tips begin to die, progressing back to larger branches, causing general deterioration of the tree or plant.
Disease Cause
Disease Cause
The withering is caused by one of two fungal pathogens, one called Monilina laxa and the other called M. fructigen. The spores overwinter on infected plant material and are then spread the following spring by wind, rain, or animal vectors. The problem will start to become noticeable in mid-spring, but will increase in severity as summer progresses and the fungus grows. If not addressed, the disease will intensify and spread to other plants in the vicinity.
Solutions
Solutions
There are a number of appropriate solutions to control fruit withering:
  1. Remove any fruit as soon as it shows any signs of infection. Do not compost.
  2. Use a fungicide prior to leaf bud and then as per manufacturers instructions throughout the season.
Prevention
Prevention
Preventative measures include:
  1. Ensuring adequate spacing between plants or trees.
  2. Staking plants that are prone to tumbling to prevent moisture or humidity build up.
  3. Prune correctly so that there is adequate air movement and remove any dead or diseased branches that may carry spores.
  4. Practice good plant hygiene by removing fallen material and destroying it as soon as possible.

Crown gall
plant poor
Crown gall
Bacterial infections can cause abnormal brown or black growths on the trunk of the tree. These are also called crown galls.
Overview
Overview
Crown gall is a bacterial disease that affects many different species of shrubs. It produces unsightly growths called galls on stems, branches, and roots. These galls stunt the growth of plants and weaken them. This is because they disrupt the flow of water and nutrients from the roots up to other areas of the plant.
Crown gall growth is generally more rapid during warm weather. There are no chemical solutions available that will kill this disease. The presence of galls does not usually cause the death of a plant, however. These galls can easily be spread to other plants through contaminated tools or soil.
Symptom Analysis
Symptom Analysis
Crown gall is most often seen on lower branches. This disease appears as deformed growths on stems, branches, or roots that gradually enlarge over time.
As the galls enlarge, they become hard and woody. Their appearance is usually brown and corky. The plant will show symptoms of stunted growth and there may be evidence of tip dieback.
Disease Cause
Disease Cause
Crown gall is caused by the bacteria Agrobacterium tumefaciens. This bacteria lives in the soil, and can survive there for many years. It is spread onto the plant by water splashing up from contaminated soil. Infected pruning tools can also spread the disease onto plants.
The bacteria enter the plant through open wounds. These could be caused by chewing insects or damage from gardening tools such as lawnmowers. Pruning cuts that have not been treated can also be infected by this bacterial disease.
Once the bacteria have entered the plant, they stimulate rapid growth in plant cells, and this is what causes the abnormal growths.
Solutions
Solutions
  1. Remove infected tissue. Established trees can survive a crown gall infection, but the galls should be removed to improve the plant's appearance. Use pruning shears to remove the gall, then treat the wound with a pruning sealer. Discard pruned material by putting it in the trash or burning it to avoid infecting other plants. Sterilize the pruning shears after removing the galls.
  2. Remove the entire plant. If a small plant is infected with a serious case of crown gall, the best option is to remove the entire plant and burn it. This will prevent bacteria from spreading to other plants.
  3. Sterilize the soil. After removing infected tissue, sterilize the soil using heat. Alternatively, plant a gall-resistant plant in the same spot.
Prevention
Prevention
To prevent crown gall, avoid introducing and spreading the bacteria that causes it.
  1. Avoid infected plants. Inspect all new plants for symptoms. Dispose of any plants that show signs of crown gall.
  2. Sanitize pruning tools. Use an approved sanitizing solution to treat pruning shears both before and after use. A freshly-mixed solution of 1 part bleach to 9 parts water will be most effective.
  3. Avoid mounding soil around the crown of the plant, keeping this area as dry as possible. Remove dead branches and leaves to prevent the occurrence of pests and diseases.
  4. Utilize beneficial bacteria. The beneficial bacterium Agrobacterium radiobacter strain 84 can be used during planting to prevent crown gall. To use, simply dip bare-rooted plants in the solution, or water rooted plants with a solution of the aforementioned bacteria.
  5. Correct overly alkaline soils. Crown gall-causing bacteria thrive in alkaline soils, so check the pH level of the soil and reduce the alkalinity.

Fire ants
plant poor
Fire ants
Fire ants gnaw on the roots of plants and are aggressive toward people.
Overview
Overview
Fire ants are a group of ants that are known for their aggressive behavior and painful stings. Some fire ants are native and others are invasive from other countries. Once they reach plants, they climb them and chew away at leaves and flower buds.
Fire ants also kill and eat beneficial insects such as caterpillars, ladybugs, mantis, and native ants. They can be a problem any time temperatures are above freezing, but new infestations are most likely to appear when brought in via contaminated material such as potting soil or mulch, or when insecticides have harmed populations of beneficial insects that would otherwise control populations of fire ants.
They can be difficult to control, especially once populations become large. Plant damage is typically minor, but fire ants can destroy seedlings.
Symptom Analysis
Symptom Analysis
The number one symptom of fire ants is seeing the ants themselves which are red or black in color. Ant mounds in the ground are also signs. Fire ant mounds rarely exceed 46 cm in diameter. If a fire ant mound is disturbed, many fast-moving, aggressive ants will emerge. These ants will bite and then painfully sting.
Even if no ants are visible, their damage might be apparent. Chewed leaf and flower edges might indicate fire ants. Fully eaten seedlings are another sign.
Solutions
Solutions
Caution: fire ants are venomous and cause painful bites which can be fatal in the case of a rare but significant allergy.
Fire ants can be a painful pest to have around for you and your plants. Keeping them under control will ensure comfortable gardening for all.
For less severe cases:
  • Physically remove mounds. Dig out and remove entire mounds (remember, they go deeper than they seem).
  • Use citrus oil. Pour citrus oil, which is toxic to fire ants, down their holes.
For severe cases:
  • Use ant bait. For a chemical solution, broadcast insecticide bait formulated for fire ants in the area around a mound. Apply the bait during a dry evening so the ants can forage for it at night. Look for products that contain Indoxacarb.
  • Release phorid flies. Introduce or promote beneficial phorid flies to gardens. These parasitic flies attack invasive fire ants.
  • Hire a professional. Some ant baits are only available to professional exterminators. For serious cases of fire ants, consider hiring a professional.
Prevention
Prevention
Fire ants become more difficult to control as they establish themselves, so try to prevent them or treat them early.
  • Monitor new material. Do not bring in any soil or plants from known infested areas, unless if they are "Quarantine Approved." Make sure to check new material for fire ants.
  • Apply insecticide. Some warm and humid areas have high fire ants populations. In these areas, spread a granular fire ants insecticide such as Varsity in the spring near gardens to prevent these unwelcome visitors.
  • Treat early. Spot treat at the first sight of any fire ants mound, as larger mounds are more difficult to treat.

Blue Spruce Watering Instructions
Blue spruce is native to the harsh surroundings of the Western U.S.'s Rocky Mountains, exposed to relatively low annual precipitation. These resilient evergreens have adapted to profit from infrequent and unpredictable rainfall patterns. Their watering needs, therefore, reflect this, with the requirement for thorough watering but also appreciable durations of dryness in between. Over-watering or a lack of appropriate drainage could easily become detrimental, as they're adapted to endure periods without excess moisture.
When Should I Water My Blue Spruce?
Introduction
Proper and timely watering plays a crucial role in maintaining the overall health and development of the blue spruce. It contributes to its optimal growth, vibrant foliage, and resistance against diseases. Therefore, understanding the appropriate signals indicating when the plant should be watered is essential.
Soil Moisture Level
The moisture level of the soil is a key indicator for watering blue spruce. Check the soil by sticking your finger about 1 to 2 inches deep into the soil. If it feels dry at this depth, it's time to water the plant. If the soil is still moist, wait before watering to avoid over-watering.
Wilting Leaves
Wilting leaves are a clear sign that blue spruce requires watering. When leaves droop or become limp, it indicates that the plant is not receiving enough moisture. Watering the plant promptly can help revive the leaves and restore plant health.
Leaf Color
Pay attention to the color of the leaves on blue spruce. If the vibrant blue-green color of the needles starts fading or turning yellow, it is a sign of water stress. Yellowing or pale leaves indicate that the plant needs water.
Needle Texture
The texture of the needles on blue spruce can reveal its water needs. If the needles feel dry or brittle to the touch, it indicates water deficiency. Healthy needles should feel slightly soft and pliable.
Seasonal Changes
Observe the seasonal changes to determine watering needs. During hot and dry periods, blue spruce may require more frequent watering to compensate for water loss. In cooler seasons or during dormant periods, water sparingly to prevent waterlogged soil.
Early Watering Risks
Watering blue spruce too early, when the soil is still moist, could risk root rot, fungus infestation, and other root diseases due to over-watering.
Late Watering Risks
Watering blue spruce too late, when it has been excessively dry for an extended period, could risk temporary wilting and might stunt the plant's growth. In extreme conditions, it can lead to plant death due to dehydration.
Conclusion
Understanding these signs is critical to effectively manage the watering schedule for the blue spruce. Proper water management not only encourages its growth and health but also prolongs its life span.
How Should I Water My Blue Spruce?
Watering Requirements
Blue spruce, has specific watering needs and sensitivities that should be considered for optimal hydration.
Watering Technique
For blue spruce, it is recommended to water deeply and infrequently. This means providing a thorough watering once the top inch of the soil feels dry to the touch. Avoid overwatering, as blue spruce is susceptible to root rot. To ensure optimal hydration, it is also beneficial to water close to the roots rather than sprinkling water on the foliage. This helps prevent moisture-related diseases and encourages deep root growth.

Checking Soil Moisture
Regularly check the moisture level of blue spruce's soil by gently inserting your finger into the top inch of the soil. If it feels dry, it's time to water. If it remains moist, delay watering to prevent overhydration.
How Much Water Does Blue Spruce Really Need?
Introduction
Blue spruce is native to cold and dry regions, used to slow but deep watering patterns that mimic the melting of snow. It can survive and even thrive in slightly moist to dry conditions due to its drought-resistance properties.
Quantity
Blue spruce needs a considerable amount of water, dictated by pot size and plant size. For a young plant in a small pot, about half a gallon of water is desirable, while mature blue spruce in larger containers or outdoors might require several gallons to cover the root zone. The ideal approach is to water the plant till the moisture reaches the depth of the root system, typically several inches below the soil surface.
Signs of Correct Watering
The signs of sufficient water intake are shiny, silvery-blue needles and new growth. If the plant exhibits drooping, wilting, or fall-off of needles, it signifies underwatering. On the other hand, yellowing of needles, root rot, and slow growth might indicate overwatering for blue spruce.
Potential Risks
The main threat of overwatering blue spruce involves introducing fungal diseases, root decay, or even plant death. If blue spruce doesn't receive enough water, it may lead to desiccation of needles, plant weakening, increased susceptibility to pests, diseases, and eventually, plant death. Balancing watering is essential for the healthy growth of blue spruce.
Conclusion
Understanding and meeting the specific water requirements tailored to blue spruce is vital to ensure it grows and develops well outside of its natural, cold, and dry habitat. Ensuring the adequate water quantity while monitoring for signs of over or underwatering can maintain the plant's health and longevity.
