What is the best way to water my Arborvitae?
If you decide to water your Arborvitae, 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 Arborvitae 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 Arborvitae too much or too little?
At times, overwatering can be the result of poor soils. Mainly, if the soil in which your Arborvitae 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 Arborvitae to a more favorable growing location. If you grow your Arborvitae 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 Arborvitae, 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 Arborvitae 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 Arborvitae may produce new growth, but that new growth may be discolored or prone to easy breakage. Another sign that the soil for your Arborvitae is too moist is if you notice standing water or that water is not draining quickly in your plant’s growing area. Underwatered Arborvitae trees will also have symptoms present in the foliage. In this case, the leaves may become sparse, brown. Usually, Arborvitae 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 Arborvitae?
A mature Arborvitae 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 Arborvitae is that this species does not tolerate standing water. As such, when in doubt, you should err on the side of not watering your Arborvitae rather than risking watering it too much.

How much water does my Arborvitae need?
The height of summer is one of the few times that you’ll need to water your Arborvitae. 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 Arborvitae.newly planted Arborvitae 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 Arborvitae through the seasons?
The Arborvitae 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 Arborvitae 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 Arborvitae at different growth stages?
Young Arborvitae 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 Arborvitae 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 Arborvitae tree.

What's the difference between watering Arborvitae indoors and outdoors?
It is far more common to grow the Arborvitae 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 Arborvitae 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 Arborvitae 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.

Dieback
Dieback Dieback
Dieback
Dieback is a tree disease that can severely affect Arborvitae. This disease causes a progressive death of tree tissues starting at the branches' tips, which can lead to the decline or death of the plant. It's primarily caused by fungi and can be aggravated by stress factors.
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.
Flower withering
Flower withering Flower withering
Flower withering
Flowers may dry out due to a sudden change in environment or because the plant has completed its normal flowering period.
Solutions: If flower withering is a natural progression due to age, there is nothing that can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible. For lack of water, immediately water the plant using room temperature rainwater, bottled spring water, or filtered tap water. Water container plants until excess water drains out the bottom; water in-ground plants until the soil is soaked but there isn’t standing water on the surface. In the event of nutritional deficiencies, the best solution is to use a granular or water-soluble liquid fertilizer, and apply it to the soil at about half the recommended dosage. Keep it off the leaves and make sure granular products are watered into the soil well. If the plant is infected with a bacterial or fungal pathogen, there is no course of treatment that cures the diseased plants. The best solution is to remove the infected plants and dispose of the plant material off-site. Do not put in a compost pile.
Underwatering
Underwatering Underwatering
Underwatering
Leaves may wilt for a variety of reasons.
Solutions: The easiest (and most obvious) way to address underwatering is to fully hydrate the plant. However, this must be done carefully. A common mistake that many gardeners make is to douse their underwatered plants with water. This can overwhelm the roots of the plant and shock its system, something that can be even more damaging than the lack of water to begin with. Instead, water thoroughly and slowly, taking breaks to let the water slowly saturate through the soil to get to the roots. Use room temperature water, as cold water might be too much of a shock. In the future, shorten the time between waterings. A good rule of thumb is to check the soil around each plant daily. If it’s dry to at least two inches down, it’s time to water. If a container plant is repeatedly drying out very quickly, repotting into a slower-draining container might be a good idea, too.
Brown spot
Brown spot Brown spot
Brown spot
This infection can cause brown spots or patches to appear on the plant.
Solutions: In minor cases of brown spot, there isn’t any need to treat the disease. However, if much of the foliage is affected and defoliation occurs, the plant will benefit from getting rid of the infection. It is recommended to start by applying organic treatment options, working up to the more potent synthetic, chemical fungicides if necessary. Organic options won’t kill the fungus, but will prevent it from spreading. Dissolve ½ teaspoon of baking soda and one teaspoon of liquid soap in a gallon of water. Using a spray bottle, spray on tops and bottoms of leaves until the mixture drips off. Repeat every two weeks until existing spots stop enlarging and new spots no longer appear. Spray a copper-based fungicidal soap on the leaves, coating the top and bottom leaf surfaces. Reapply as directed on the product label. Copper penetrates the leaf surface and prevents germination of spores so the fungus cannot spread. Apply an all-purpose fungicide to the entire plant, following the label instructions carefully.
Aged yellow and dry
Aged yellow and dry Aged yellow and dry
Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Solutions: If the yellowing and drying of leaves and flowers is a natural progression due to age, nothing can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible.

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

Flower withering
plant poor
Flower withering
Flowers may dry out due to a sudden change in environment or because the plant has completed its normal flowering period.
Overview
Overview
Flower withering occurs when flowers become weak, droopy, wilted, or faded until they can’t be revived. During withering, they begin to wrinkle and shrink until the flower becomes completely dry or dead.
Any flowers, regardless of the plant type or the climate they are grown in, are susceptible to withering. It is a worldwide problem across houseplants, herbs, flowering ornamentals, trees, shrubs, garden vegetables, and food crops.
Unlike wilting—which withering is often confused with—withering can be caused by different things and is often due to more than a lack of water. Withering can be fatal in severe cases.
Symptom Analysis
Symptom Analysis
Flower withering progresses from very mild cases to severe occurrences that kill the flower. The severity of the symptoms is related to the cause and how long the condition is allowed to progress before action is taken.
  • Wilted, droopy flowers
  • Petals and leaves begin to wrinkle
  • Brown papery streaks or spots appear on the petals and leaf tips
  • Flowerhead shrink in size
  • Petal color fades
  • Yellowing leaves
  • Complete death of the flower
Disease Cause
Disease Cause
The main causes of flower withering include natural age progress, lack of water, nutritional deficiencies, and bacterial or fungal diseases. It’s critical to determine the underlying cause when flower withering is noticed. This will guide the best course of action, if treatment is possible.
Check the soil for moisture and then closely examine the entire plant for signs of nutrient deficiencies. If neither of those appears to be the cause then cut open the stem below a flower. If a cross-section reveals brown or rust-colored stains it is safe to assume that this is a bacterial or fungal infection.
If the flower is nearing the end of its normal lifespan, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence, or cell aging and death. Cell division stops and the plant begins breaking down resources within the flower to use in other parts of the plant.
In all other cases, flower withering happens when the plant seals off the stem as a defense mechanism, stopping transport within the vascular system. This prevents further water loss through the flowers but also stops bacteria and fungi from moving to healthy parts of the plant. Once water and nutrient transport stops, the flower begins to wither and ultimately die.

Underwatering
Leaves may wilt for a variety of reasons.
Overview
Overview
Underwatering plants is one of the quickest ways to kill them. This is something that most gardeners are well aware of. Unfortunately, knowing exactly how much water a plant needs can be tricky, especially considering that underwatering and overwatering present similar symptoms in plants.
Therefore, it’s important to be vigilant and attentive to each plants’ individual needs.
Symptom Analysis
Symptom Analysis
As mentioned earlier, overwatering and underwatering present similar symptoms in plants. These symptoms include poor growth, wilted leaves, defoliation, and brown leaf tips or margins. Ultimately, both underwatering and overwatering can lead to the death of a plant.
The easiest way to determine whether a plant has too much water or too little is to look at the leaves. If underwatering is the culprit, the leaves will look brown and crunchy, while if it’s overwatering, they will appear yellow or a pale green in color.
When this issue first begins, there may be no noticeable symptoms at all, particularly in hardy or drought-tolerant plants. However, they will begin to wilt once they start suffering from a lack of water. The edges of the plant’s leaves will become brown or curled. Soil pulling away from the edges of the planter is a telltale sign, or a crispy, brittle stem.
Prolonged underwatering can cause a plant’s growth to become stunted. The leaves might drop and the plant can be more susceptible to pest infestations, too.
Disease Cause
Disease Cause
Underwatering is caused by, quite simply, not watering plants often or deeply enough. There is a heightened risk of underwatering if any of these situations apply:
  • Extreme heat and dry weather (when growing outdoors)
  • Grow lights or indoor lighting that is too bright or intense for the type of plant
  • Using fast-draining growing media such as sand

Brown spot
plant poor
Brown spot
This infection can cause brown spots or patches to appear on the plant.
Overview
Overview
Discolored spots on the foliage of plants are one of the most common disease problems people observe. These spots are caused by fungal and bacterial diseases, with most infections related to a fungal pathogen.
Brown spot can occurs on all houseplants, flowering ornamentals, vegetable plants, and leaves of trees, bushes, and shrubs. No plants are resistant to it, and the problem is worse in warm, wet environments. It can occur at any point in the life stage as long as leaves are present.
Small brownish spots appear on the foliage and enlarge as the disease progresses. In severe cases, the plant or tree is weakened when the lesions interrupt photosynthesis or cause defoliation.
Symptom Analysis
Symptom Analysis
In most cases, brown spot only affects a small percentage of the whole plant, appearing on a small amount of the leaves. A small infection only puts minor stress on the plant. However, if left untreated and the disease progresses over numerous seasons, it will severely impact the health and productivity of the infected specimen.
  • Sporulation begins (reproduction of the fungal spores), and tiny spots appear on leaves.
  • Placement is often random and scattered as diseases are spread through raindrops.
  • May appear on lower leaves and the interior of the plant where humidity is higher.
  • Brown spots enlarge and grow large enough to touch neighboring spots to form a more prominent blotch.
  • Leaf margins may turn yellow.
  • Tiny black dots (fruiting bodies of the fungi) appear in the dead spots.
  • Blotches grow in size until the entire leaf is brown.
  • The leaf falls off the plant.
Severe Symptoms
  • Partial or complete premature defoliation
  • Reduced growth
  • Increased susceptibility to pests and other diseases
Disease Cause
Disease Cause
Brown spot, or leaf spot, is a common descriptive term given to several diseases affecting the leaves of plants and trees. Around 85% of diseases exhibiting leaf spots are due to fungus or fungus-like organisms. Sometimes brown spot is caused by a bacterial infection, or insect activity with similar symptoms.
When conditions are warm and the leaf surfaces are wet, fungal spores being transported by wind or rain land on the surface and cling to it. They do not rupture the cell walls but grow in the space between the plant plasma membrane and the plant cell wall. As the spores reproduce, they release toxins and enzymes that cause necrotic spots (i.e., dead tissue) on the leaves, allowing the fungi to consume the products released when the cells degrade.

Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Overview
Overview
Regardless of the type of plant or where it is grown, at some point, it will begin to aged yellow and dry. This is a natural, unavoidable process that happens when the plant has completed all of the steps in its life.
Annual plants go through this process at the end of a single growing season. Perennial plants live for multiple years, if not tens or hundreds of years, but will still ultimately exhibit these symptoms.
Symptom Analysis
Symptom Analysis
When plants have progressed through their natural developmental stages and are nearing the end of their lifecycle, they begin showing signs of decline. Leaves will start to yellow and droop, and over time they turn papery brown and dry.
Once completely dry, the leaves begin to fall from the plant until the entire plant has dried out.
Disease Cause
Disease Cause
At the end of its life, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence or natural aging and death. Cell division stops, and the plant begins catabolizing resources to use in other parts of the plant.
As this happens, the tissues begin yellow and drying until the entire plant is desiccated and perishes.

Its ground cover is distinctive due to its leaves, which can be white, light yellow, or a variegated combination. These leaves, when added to the white flowers, create an appearance of snow that gives the plant its name.
Sweet william
Sweet william
There are two thoughts on the origin of the sweet william name. The first is that it was named after the Duke of Cumberland, William Augustus. The second is that the name came from the writings of Thomas Tusser, an English poet. In either case, this old-fashioned garden plant (Dianthus barbatus) is a lovely addition to any space.

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.

Flower withering
Flower withering Flower withering Flower withering
Flowers may dry out due to a sudden change in environment or because the plant has completed its normal flowering period.
Solutions: If flower withering is a natural progression due to age, there is nothing that can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible. For lack of water, immediately water the plant using room temperature rainwater, bottled spring water, or filtered tap water. Water container plants until excess water drains out the bottom; water in-ground plants until the soil is soaked but there isn’t standing water on the surface. In the event of nutritional deficiencies, the best solution is to use a granular or water-soluble liquid fertilizer, and apply it to the soil at about half the recommended dosage. Keep it off the leaves and make sure granular products are watered into the soil well. If the plant is infected with a bacterial or fungal pathogen, there is no course of treatment that cures the diseased plants. The best solution is to remove the infected plants and dispose of the plant material off-site. Do not put in a compost pile.

Underwatering
Underwatering Underwatering Underwatering
Leaves may wilt for a variety of reasons.
Solutions: The easiest (and most obvious) way to address underwatering is to fully hydrate the plant. However, this must be done carefully. A common mistake that many gardeners make is to douse their underwatered plants with water. This can overwhelm the roots of the plant and shock its system, something that can be even more damaging than the lack of water to begin with. Instead, water thoroughly and slowly, taking breaks to let the water slowly saturate through the soil to get to the roots. Use room temperature water, as cold water might be too much of a shock. In the future, shorten the time between waterings. A good rule of thumb is to check the soil around each plant daily. If it’s dry to at least two inches down, it’s time to water. If a container plant is repeatedly drying out very quickly, repotting into a slower-draining container might be a good idea, too.

Brown spot
Brown spot Brown spot Brown spot
This infection can cause brown spots or patches to appear on the plant.
Solutions: In minor cases of brown spot, there isn’t any need to treat the disease. However, if much of the foliage is affected and defoliation occurs, the plant will benefit from getting rid of the infection. It is recommended to start by applying organic treatment options, working up to the more potent synthetic, chemical fungicides if necessary. Organic options won’t kill the fungus, but will prevent it from spreading. Dissolve ½ teaspoon of baking soda and one teaspoon of liquid soap in a gallon of water. Using a spray bottle, spray on tops and bottoms of leaves until the mixture drips off. Repeat every two weeks until existing spots stop enlarging and new spots no longer appear. Spray a copper-based fungicidal soap on the leaves, coating the top and bottom leaf surfaces. Reapply as directed on the product label. Copper penetrates the leaf surface and prevents germination of spores so the fungus cannot spread. Apply an all-purpose fungicide to the entire plant, following the label instructions carefully.

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.

Flower withering
plant poor
Flower withering
Flowers may dry out due to a sudden change in environment or because the plant has completed its normal flowering period.
Overview
Overview
Flower withering occurs when flowers become weak, droopy, wilted, or faded until they can’t be revived. During withering, they begin to wrinkle and shrink until the flower becomes completely dry or dead.
Any flowers, regardless of the plant type or the climate they are grown in, are susceptible to withering. It is a worldwide problem across houseplants, herbs, flowering ornamentals, trees, shrubs, garden vegetables, and food crops.
Unlike wilting—which withering is often confused with—withering can be caused by different things and is often due to more than a lack of water. Withering can be fatal in severe cases.
Symptom Analysis
Symptom Analysis
Flower withering progresses from very mild cases to severe occurrences that kill the flower. The severity of the symptoms is related to the cause and how long the condition is allowed to progress before action is taken.
  • Wilted, droopy flowers
  • Petals and leaves begin to wrinkle
  • Brown papery streaks or spots appear on the petals and leaf tips
  • Flowerhead shrink in size
  • Petal color fades
  • Yellowing leaves
  • Complete death of the flower
Disease Cause
Disease Cause
The main causes of flower withering include natural age progress, lack of water, nutritional deficiencies, and bacterial or fungal diseases. It’s critical to determine the underlying cause when flower withering is noticed. This will guide the best course of action, if treatment is possible.
Check the soil for moisture and then closely examine the entire plant for signs of nutrient deficiencies. If neither of those appears to be the cause then cut open the stem below a flower. If a cross-section reveals brown or rust-colored stains it is safe to assume that this is a bacterial or fungal infection.
If the flower is nearing the end of its normal lifespan, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence, or cell aging and death. Cell division stops and the plant begins breaking down resources within the flower to use in other parts of the plant.
In all other cases, flower withering happens when the plant seals off the stem as a defense mechanism, stopping transport within the vascular system. This prevents further water loss through the flowers but also stops bacteria and fungi from moving to healthy parts of the plant. Once water and nutrient transport stops, the flower begins to wither and ultimately die.
Solutions
Solutions
If flower withering is a natural progression due to age, there is nothing that can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible.
For lack of water, immediately water the plant using room temperature rainwater, bottled spring water, or filtered tap water. Water container plants until excess water drains out the bottom; water in-ground plants until the soil is soaked but there isn’t standing water on the surface.
In the event of nutritional deficiencies, the best solution is to use a granular or water-soluble liquid fertilizer, and apply it to the soil at about half the recommended dosage. Keep it off the leaves and make sure granular products are watered into the soil well.
If the plant is infected with a bacterial or fungal pathogen, there is no course of treatment that cures the diseased plants. The best solution is to remove the infected plants and dispose of the plant material off-site. Do not put in a compost pile.
Prevention
Prevention
This is definitely one of those instances where prevention is more effective than cure. Here are some preventative measures for avoiding premature flower withering.
  • Water plants according to their needs -- either keep the soil slightly moist or allow the top inch or two to dry out before watering again.
  • Fertilize lightly on a consistent basis, depending upon the plant’s growth. Quick-growing plants and those that flower or develop fruit will need more frequent fertilizing than slow-growing plants.
  • Purchase plants that are certified disease- or pathogen-free.
  • Look for disease-resistant cultivars.
  • Isolate plants showing disease symptoms to prevent the spread to neighboring plants.
  • Practice good plant hygiene by removing any fallen plant material as soon as possible.

Underwatering
Leaves may wilt for a variety of reasons.
Overview
Overview
Underwatering plants is one of the quickest ways to kill them. This is something that most gardeners are well aware of. Unfortunately, knowing exactly how much water a plant needs can be tricky, especially considering that underwatering and overwatering present similar symptoms in plants.
Therefore, it’s important to be vigilant and attentive to each plants’ individual needs.
Symptom Analysis
Symptom Analysis
As mentioned earlier, overwatering and underwatering present similar symptoms in plants. These symptoms include poor growth, wilted leaves, defoliation, and brown leaf tips or margins. Ultimately, both underwatering and overwatering can lead to the death of a plant.
The easiest way to determine whether a plant has too much water or too little is to look at the leaves. If underwatering is the culprit, the leaves will look brown and crunchy, while if it’s overwatering, they will appear yellow or a pale green in color.
When this issue first begins, there may be no noticeable symptoms at all, particularly in hardy or drought-tolerant plants. However, they will begin to wilt once they start suffering from a lack of water. The edges of the plant’s leaves will become brown or curled. Soil pulling away from the edges of the planter is a telltale sign, or a crispy, brittle stem.
Prolonged underwatering can cause a plant’s growth to become stunted. The leaves might drop and the plant can be more susceptible to pest infestations, too.
Disease Cause
Disease Cause
Underwatering is caused by, quite simply, not watering plants often or deeply enough. There is a heightened risk of underwatering if any of these situations apply:
  • Extreme heat and dry weather (when growing outdoors)
  • Grow lights or indoor lighting that is too bright or intense for the type of plant
  • Using fast-draining growing media such as sand
Solutions
Solutions
The easiest (and most obvious) way to address underwatering is to fully hydrate the plant. However, this must be done carefully. A common mistake that many gardeners make is to douse their underwatered plants with water. This can overwhelm the roots of the plant and shock its system, something that can be even more damaging than the lack of water to begin with.
Instead, water thoroughly and slowly, taking breaks to let the water slowly saturate through the soil to get to the roots. Use room temperature water, as cold water might be too much of a shock.
In the future, shorten the time between waterings. A good rule of thumb is to check the soil around each plant daily. If it’s dry to at least two inches down, it’s time to water. If a container plant is repeatedly drying out very quickly, repotting into a slower-draining container might be a good idea, too.
Prevention
Prevention
Always check the soil before watering. If the top inch of soil feels moist, though not wet, the watering is perfect. If it’s dry, water it immediately. If it feels soggy, you avoid watering until it dries out a bit more.
Also, make sure the lighting is sufficient for the species. Plants grow faster and need more water when there is intense light or lots of heat. Being aware of these conditions and modifying them, if possible, is a good way to prevent underwatering. Many container plants are potted in soil mixtures mean to be well-draining. Adding materials that retain moisture, like compost or peat moss, can also prevent these symptoms.
Other tips to prevent underwatering include:
  • Choose pots with adequately-sized drainage holes
  • Avoid warm temperatures
  • Use large pots with additional soil (these take longer to dry out)
  • Avoid terracotta pots, which lose water quickly

Brown spot
plant poor
Brown spot
This infection can cause brown spots or patches to appear on the plant.
Overview
Overview
Discolored spots on the foliage of plants are one of the most common disease problems people observe. These spots are caused by fungal and bacterial diseases, with most infections related to a fungal pathogen.
Brown spot can occurs on all houseplants, flowering ornamentals, vegetable plants, and leaves of trees, bushes, and shrubs. No plants are resistant to it, and the problem is worse in warm, wet environments. It can occur at any point in the life stage as long as leaves are present.
Small brownish spots appear on the foliage and enlarge as the disease progresses. In severe cases, the plant or tree is weakened when the lesions interrupt photosynthesis or cause defoliation.
Symptom Analysis
Symptom Analysis
In most cases, brown spot only affects a small percentage of the whole plant, appearing on a small amount of the leaves. A small infection only puts minor stress on the plant. However, if left untreated and the disease progresses over numerous seasons, it will severely impact the health and productivity of the infected specimen.
  • Sporulation begins (reproduction of the fungal spores), and tiny spots appear on leaves.
  • Placement is often random and scattered as diseases are spread through raindrops.
  • May appear on lower leaves and the interior of the plant where humidity is higher.
  • Brown spots enlarge and grow large enough to touch neighboring spots to form a more prominent blotch.
  • Leaf margins may turn yellow.
  • Tiny black dots (fruiting bodies of the fungi) appear in the dead spots.
  • Blotches grow in size until the entire leaf is brown.
  • The leaf falls off the plant.
Severe Symptoms
  • Partial or complete premature defoliation
  • Reduced growth
  • Increased susceptibility to pests and other diseases
Disease Cause
Disease Cause
Brown spot, or leaf spot, is a common descriptive term given to several diseases affecting the leaves of plants and trees. Around 85% of diseases exhibiting leaf spots are due to fungus or fungus-like organisms. Sometimes brown spot is caused by a bacterial infection, or insect activity with similar symptoms.
When conditions are warm and the leaf surfaces are wet, fungal spores being transported by wind or rain land on the surface and cling to it. They do not rupture the cell walls but grow in the space between the plant plasma membrane and the plant cell wall. As the spores reproduce, they release toxins and enzymes that cause necrotic spots (i.e., dead tissue) on the leaves, allowing the fungi to consume the products released when the cells degrade.
Solutions
Solutions
In minor cases of brown spot, there isn’t any need to treat the disease. However, if much of the foliage is affected and defoliation occurs, the plant will benefit from getting rid of the infection. It is recommended to start by applying organic treatment options, working up to the more potent synthetic, chemical fungicides if necessary.
Organic options won’t kill the fungus, but will prevent it from spreading.
  1. Dissolve ½ teaspoon of baking soda and one teaspoon of liquid soap in a gallon of water. Using a spray bottle, spray on tops and bottoms of leaves until the mixture drips off. Repeat every two weeks until existing spots stop enlarging and new spots no longer appear.
  2. Spray a copper-based fungicidal soap on the leaves, coating the top and bottom leaf surfaces. Reapply as directed on the product label. Copper penetrates the leaf surface and prevents germination of spores so the fungus cannot spread.
  3. Apply an all-purpose fungicide to the entire plant, following the label instructions carefully.
Prevention
Prevention
Like many other diseases, it is easier to prevent brown spot than cure it, and this is done through cultural practices.
  • Clear fall leaves from the ground before winter to minimize places where fungi and bacteria can overwinter.
  • Maintain good air movement between plants through proper plant spacing.
  • Increase air circulation through the center of plants through pruning.
  • Thoroughly clean all pruning tools after working with diseased plants.
  • Never dispose of disease plant material in a compost pile.
  • Avoid overhead watering to keep moisture off of the foliage.
  • Keep plants healthy by providing adequate sunlight, water, and fertilizer.

Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Overview
Overview
Regardless of the type of plant or where it is grown, at some point, it will begin to aged yellow and dry. This is a natural, unavoidable process that happens when the plant has completed all of the steps in its life.
Annual plants go through this process at the end of a single growing season. Perennial plants live for multiple years, if not tens or hundreds of years, but will still ultimately exhibit these symptoms.
Symptom Analysis
Symptom Analysis
When plants have progressed through their natural developmental stages and are nearing the end of their lifecycle, they begin showing signs of decline. Leaves will start to yellow and droop, and over time they turn papery brown and dry.
Once completely dry, the leaves begin to fall from the plant until the entire plant has dried out.
Disease Cause
Disease Cause
At the end of its life, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence or natural aging and death. Cell division stops, and the plant begins catabolizing resources to use in other parts of the plant.
As this happens, the tissues begin yellow and drying until the entire plant is desiccated and perishes.
Solutions
Solutions
If the yellowing and drying of leaves and flowers is a natural progression due to age, nothing can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible.
Prevention
Prevention
Unfortunately, there is no way to prevent plants from dying of “old age.” To help prolong their life, and put off symptoms of aged yellow and dry for as long as possible, take care of them by giving them enough water, fertilizing them appropriately, and making sure they get enough sunlight.

Arborvitae Watering Instructions
Arborvitae hails from regions in North America, including the eastern United States and Canada. It thrives in various habitats such as woodlands, swamps, and moist areas with well-drained soil. This plant's native environment points to its preference for consistent moisture. Regular watering is essential for arborvitae, mimicking its natural habitat where it receives ample rainfall. However, it's important to avoid overwatering and ensure the soil remains moist, but not overly saturated, to prevent root rot.
When Should I Water My Arborvitae?
Introduction
Proper and timely watering plays a crucial role in maintaining the overall health and development of the arborvitae. 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
Check the soil moisture by inserting your finger 1 to 2 inches deep into the soil. If it feels dry at that depth, it's time to water the arborvitae plant.
Leaf Wilting
If the leaves of the arborvitae start to droop or appear wilted, it's a sign that the plant requires water. The drooping leaves are the plant's way of conserving water when it's under stress.
Yellowing Leaves
Yellowing or browning leaves on the arborvitae indicate water stress and a need for irrigation. When the leaves lose their vibrant green color and start turning yellow, it's a clear indication of watering requirements.
Cracked Soil Surface
A cracked soil surface around the arborvitae plant is a sign that the soil is excessively dry. The cracks indicate the need for immediate watering to prevent the plant from withering.
Stalled Growth
If the arborvitae plant's growth seems to have slowed down or come to a halt, it may be due to insufficient water. Proper watering can help stimulate growth and ensure healthy development.
Pre-Hibernation Watering
Before the arborvitae enters its dormant or hibernation phase, it's essential to provide thorough watering. This ensures the plant has enough moisture reserves to survive the winter period.
Risk of Overwatering
Overwatering the arborvitae can lead to root rot, fungal diseases, and general plant decline. It's crucial to avoid excessive watering and only provide water when the plant truly needs it.
Risk of Underwatering
Neglecting to water the arborvitae when it is in need can result in wilting, stunted growth, and potentially plant death. It's important to address watering needs promptly to prevent dehydration.
Conclusion

Moderate - arborvitae generally prefers water at room temperature (around 68-72°F or 20-22°C). Avoid using water that is too cold or too hot as extreme temperatures can shock the plant.
How Do Arborvitae's Watering Needs Change with the Seasons?
How to Water arborvitae in Spring?
As springtime commences, so does the new growth of arborvitae. During this period, ample watering is key to replacing the water the plant loses as new foliage emerges. A deep and thorough watering once a week may be necessary, especially if rainfall is infrequent. Ensure the soil is well-drained and does not become waterlogged as this can lead to root rot.
How to Water arborvitae in Summer?
During the warmer summer months, arborvitae requires more consistent watering. The increased temperature and sunlight can cause rapid evaporation which the plant may struggle to keep pace with. Nevertheless, it's crucial not to overwater; instead, strive for maintaining a consistently moist soil environment. Be cautious of signs of drought stress, such as browning leaves or reduced growth.
How to Water arborvitae in Autumn?
As autumn approaches and growth slows down, watering requirements for arborvitae also decrease. While cooler temperatures reduce evaporation, this plant still needs adequate watering to prepare for winter. Ensure the soil remains slightly moist and adjust watering as needed depending on rainfall levels and temperature.
How to Water arborvitae in Winter?
In winter, arborvitae enters a period of dormancy, meaning it requires less watering. However, ensure the plant does not completely dry out. Watch for symptoms of excessive dryness such as foliage browning or shedding, especially before a hard frost when moisture can prevent freeze damage. Water sparingly but deeply to reach the roots without causing waterlogging, as cold, wet conditions can lead to root diseases.
What Expert Tips Can Enhance Arborvitae Watering Routine?
Moisture Meter
Using a moisture meter can help assess arborvitae's deeper soil moisture needs and prevent over or under-watering. This plant prefers its soil to be mostly dry before the next watering, and a meter can effectively measure this.
Watering Time
Watering arborvitae early in the morning allows the water to penetrate the soil thoroughly before the high evaporation rates of mid-day. It also helps prevent fungal diseases by minimizing the plant's exposure to dampness.
Avoid Over-watering
One common mistake when watering arborvitae is over-watering. The plant prefers well-drained soil, and excessive water can lead to root rot and other issues. To avoid over-watering, make sure the soil has dried out at least 2 inches deep before watering again.
Deep Watering
Instead of frequent shallow watering, arborvitae benefits from deep watering. This encourages the plant's roots to grow deeper and establish a stronger foundation. Deep watering also helps the soil retain moisture for longer periods, reducing the need for frequent watering.
Mulching
Applying a layer of organic mulch around the base of arborvitae can help retain soil moisture and regulate temperature. Mulch also reduces weed growth and improves the overall health of the plant.
Signs of Thirst

Adjusting Watering in Special Conditions
During a heatwave, arborvitae may require more frequent watering due to increased evaporation and water loss. However, be cautious not to over-water as the plant still prefers well-drained soil. During extended periods of rain, reduce watering frequency to prevent waterlogging and root rot. When arborvitae is stressed, such as after transplanting, monitor moisture levels closely and adjust watering accordingly.
Rain Gauge
Using a rain gauge can help you determine whether arborvitae has received enough water from rainfall. If the gauge shows that the plant has received adequate moisture, you can adjust your watering schedule accordingly.
Proper Drainage
Ensuring proper drainage is vital for arborvitae as it helps prevent waterlogging and root rot. If your soil has poor drainage, consider amending it with organic matter or creating raised beds to improve water flow.
Assessing Soil Moisture
To assess soil moisture beyond the surface level, insert a screwdriver or thin rod into the soil. If it goes in smoothly and comes out without any significant resistance, the soil is likely adequately moist. If it requires significant effort to insert or comes out with wet clumps, the soil is overly saturated and may need time to dry out.
Considering Hydroponics? How to Manage a Water-Grown Arborvitae?
Overview of Hydroponics
Arborvitae is a plant that can be grown successfully using hydroponics, a method of growing plants without soil. Hydroponics involves growing plants in a water-based environment with added nutrients. This method can offer more control over nutrient levels, water availability, and growing conditions, which may be beneficial for the growth and management of arborvitae.
