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

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

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

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.

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.

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
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.

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.

Lighting
Full sun
Eastern hemlock has a preference for full intensity light exposure, but also displays resilience in semi-lit or completely shadowed areas. The plant’s native environment exhibits these light conditions, promoting healthy growth. Overexposure can be detrimental, though underexposure does not significantly impact its health.
Best Sunlight Practices
Transplant
6-12 inches
To ensure eastern hemlock's successful transplant, choose the ideal period of late-autumn to pre-winter months. This allows roots to establish before harsh weather arrives. Select a well-drained, shady location for eastern hemlock, and, when necessary, follow transplant tips for supportive growth.
Transplant Techniques
Temperature
-30 - 35 ℃
The eastern hemlock grows in a temperate climate and prefers a temperature range of 32 to 90 ℉ (0 to 32 ℃). It thrives in cooler temperatures and can tolerate winter frosts. During the summer months, it is recommended to provide shade to avoid excessive heat exposure.
Temp for Healthy Growth
Pruning
Winter
This coniferous evergreen is prized for its pyramidal shape and needle-like leaves. For eastern hemlock, annually prune in winter to maintain its dense form. Trim back new growth, avoiding older wood as it doesn't regenerate well. Remove dead or diseased branches to promote health and prevent pests. Pruning benefits eastern hemlock by encouraging a strong structure and enhancing its natural beauty, important in ornamental landscaping.
Pruning techniques
Propagation
Autumn,Winter
Eastern hemlock propagates ideally during autumn and winter through the methods of layering, cutting, and sowing. Propagation can be moderately challenging, and signs of successful propagation include new shoot growth. Maintain optimal humidity and semi-shaded environments for better results.
Propagation Techniques
Pollination
Difficult
The eastern hemlock primarily relies on wind for its pollination process. Instead of having flashy attractants, it's perfectly adapted to a passive approach, calmly waiting for wind currents to carry its tiny pollen particles. The timing of pollination is typically during spring, accompanied by a density of cones to improve the efficacy of wind pollination.
Pollination Techniques
Non-base branch withering
Non-base branch withering is a condition affecting Eastern hemlock. It causes branch decline and discoloration, leading to subsequent death if untreated. The disease poses key challenges for the health and survival of Eastern hemlock.

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.

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
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.
Prevention
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.

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

Indoor plants require adequate lighting for optimal growth. When natural sunlight is insufficient, particularly in winter or in less sunny spaces, artificial lights offer a vital solution, promoting faster, healthier growth.
1. Choose the right type of artificial light: LED lights are a popular choice for indoor plant lighting because they can be customized to provide the specific wavelengths of light that your plants need.
Full sun plants need 30-50W/sq ft of artificial light, partial sun plants need 20-30W/sq ft, and full shade plants need 10-20W/sq ft.
2. Determine the appropriate distance: Place the light source 12-36 inches above the plant to mimic natural sunlight.
3. Determine the duration: Mimic the length of natural daylight hours for your plant species. most plants need 8-12 hours of light per day.
Important Symptoms
Symptoms of Insufficient Light in %s
Eastern hemlock thrives in full sunlight but is sensitive to heat. As a plant commonly grown outdoors with abundant sunlight, it may exhibit subtle symptoms of light deficiency when placed in rooms with suboptimal lighting.
View more
(Symptom details and solutions)
Small leaves
New leaves may grow smaller in size compared to the previous ones once they have matured.
Leggy or sparse growth
The spaces between leaves or stems of your eastern hemlock may become longer, resulting in a thin and stretched-out appearance. This can make the plant look sparse and weak, and it may easily break or lean due to its own weight.
Faster leaf drop
When plants are exposed to low light conditions, they tend to shed older leaves early to conserve resources. Within a limited time, these resources can be utilized to grow new leaves until the plant's energy reserves are depleted.
Slower or no new growth
Eastern hemlock enters a survival mode when light conditions are poor, which leads to a halt in leaf production. As a result, the plant's growth becomes delayed or stops altogether.
Lighter-colored new leaves
Insufficient sunlight can cause leaves to develop irregular color patterns or appear pale. This indicates a lack of chlorophyll and essential nutrients.
Solutions
1. To ensure optimal growth, gradually move plants to a sunnier location each week, until they receive at least 6 hours of direct sunlight daily. Use a south-facing window and keep curtains open during the day for maximum sunlight exposure and nutrient accumulation.2. To provide additional light for your plant, consider using artificial light if it's large or not easily movable. Keep a desk or ceiling lamp on for at least 8 hours daily, or invest in professional plant grow lights for ample light.
Symptoms of Excessive light in %s
Eastern hemlock thrives in full sun exposure but is sensitive to heat. Although sunburn symptoms occasionally occur, they are unable to withstand intense sunlight in high-temperature environments.
View more
(Symptom details and solutions)
Chlorosis
Chlorosis is a condition where the plant's leaves lose their green color and turn yellow. This is due to the breakdown of chlorophyll from excessive sunlight, which negatively affects the plant's ability to photosynthesize.
Sunscald
Sunscald occurs when the plant's leaves or stems are damaged by intense sunlight exposure. It appears as pale, bleached, or necrotic areas on the plant tissue and can reduce the plant's overall health.
Leaf Curling
Leaf curling is a symptom where leaves curl or twist under extreme sunlight conditions. This is a defense mechanism used by the plant to reduce its surface area exposed to sunlight, minimizing water loss and damage.
Wilting
Wilting occurs when a plant loses turgor pressure and its leaves and stems begin to droop. Overexposure to sunlight can cause wilting by increasing the plant's water loss through transpiration, making it difficult for the plant to maintain adequate hydration.
Leaf Scorching
Leaf scorching is a symptom characterized by the appearance of brown, dry, and crispy edges or patches on leaves due to excessive sunlight. This can lead to a reduction in photosynthetic capacity and overall plant health.
Solutions
1. Move your plant to the optimal position where it can receive abundant sunlight but also have some shade. An east-facing window is an ideal choice as the morning sunlight is gentler. This way, your plant can enjoy ample sunlight while reducing the risk of sunburn.2. It is recommended to trim off any completely dehydrated or withered parts of the plant.

Essentials
The eastern hemlock grows in a temperate climate and prefers a temperature range of 32 to 90 ℉ (0 to 32 ℃). It thrives in cooler temperatures and can tolerate winter frosts. During the summer months, it is recommended to provide shade to avoid excessive heat exposure.
Regional wintering strategies
Eastern hemlock is highly cold-tolerant and does not require additional frost protection measures during winter. However, before the first freeze in autumn, it is recommended to water the plant generously to ensure the soil remains moist and enters a frozen state. This helps prevent drought and water scarcity for the plant during winter and early spring.
Important Symptoms
Symptoms of Low Temperature in Eastern hemlock
Eastern hemlock is extremely cold-tolerant, but the winter temperature should be maintained above {Limit_growth_temperature}. If the temperature drops below this threshold, although there may not be any noticeable changes during winter, the branches may become brittle and dry during springtime, and no new shoots will emerge.
Solutions
In spring, prune away any dead branches that have failed to produce new leaves.
Symptoms of High Temperature in Eastern hemlock
Eastern hemlock is not tolerant to high temperatures. When the temperature exceeds {Suitable_growth_temperature_max}, it may experience significant leaf drop, and in severe cases, the entire plant may wither and die.
Solutions
Trim away the sunburned and dried-up parts. Move the plant to a location that provides shade from the midday and afternoon sun, or use a shade cloth to create shade. Water the plant in the morning and evening to keep the soil moist.
