Why is My Arborvitae Turning Brown in Summer?

If you have an arborvitae that’s turning brown in summer, it’s likely due to one of two reasons: drought or insect damage. Browning can also be caused by disease, but this is less common. If your arborvitae is in a location that gets full sun and has well-drained soil, it’s probably not getting enough water.

Water deeply once or twice a week during dry spells. If you suspect insect damage, look for signs of chewing or stinging insects such as aphids, caterpillars, or spider mites. These pests can be controlled with pesticides, but it’s best to consult a professional before using any chemicals on your plants.

If your arborvitae is turning brown in summer, it may be due to heat stress. Arborvitae are native to North America and prefer cooler temperatures. They can tolerate some heat, but if they’re exposed to too much sun and heat, the leaves will start to turn brown.

If you live in an area with hot summers, make sure to give your arborvitae some afternoon shade. You can also try misting the foliage with water on hot days. If the leaves are still turning brown, you may need to move the plant to a cooler location or provide more shade.

Arborvitae Turning Brown Too Much Water

If your arborvitae is turning brown, it may be because it’s getting too much water. Over-watering can cause the needles to turn brown and drop off the tree. It can also lead to root rot, which can kill the tree.

If you think your arborvitae is getting too much water, check the soil around the tree. If it’s soggy or wet, you may need to adjust your watering schedule.

If you’ve noticed that your arborvitae tree’s needles are turning brown, don’t panic! There are a few possible explanations for this phenomenon. First, it could be a natural occurrence called “winterburn.”

This happens when the needles are exposed to harsh winter conditions like wind and ice. The damage is usually most severe on the side of the tree that faces the prevailing winds. Winterburn is a cosmetic issue and won’t kill your tree, so there’s no need to treat it.

Just wait until spring, when the new growth will cover up the damaged needles. Another possibility is that your arborvitae is suffering from drought stress. This is a more serious problem, since it can eventually kill the tree if not addressed.

If you think drought stress might be to blame, check to see if the soil around your arborvitae is dry. If it is, give your tree a deep watering (enough to soak down to the roots) once a week until conditions improve. You may also need to adjust your sprinklers so they’re providing adequate coverage.

A third possibility is that your arborvitae has been attacked by insects or diseases. These problems are best addressed by a certified arborist or other professional with experience in diagnosing and treating such issues. So if you notice browning needles on your arborvitae, don’t despair!

There are several potential causes and solutions for this problem.

Your arborvitae may be turning brown inside for a few reasons. The most common is overwatering, as this can lead to root rot. If the soil is constantly wet, it doesn’t allow the roots to get the oxygen they need, and they will start to die.

Another possibility is that your arborvitae is getting too much sun. This can cause the leaves to scorch and turn brown. If you think either of these might be the problem, try adjusting your watering and pruning accordingly.

Newly Planted Arborvitae Turning Brown

If you’ve recently planted arborvitae and it’s already turning brown, don’t despair. There are a few possible reasons why this is happening, and most of them are easily remedied. One possibility is that the tree is not getting enough water.

Arborvitae are drought-resistant once they’re established, but when they’re first planted, they need to be watered regularly (about once a week) to help them get established. If you think this might be the problem, give your tree a good soaking and see if it greens up within a few days. Another possibility is that the tree is getting too much water.

This can happen if you’re watering it every day or if the area around the tree is particularly wet or soggy. If you think over-watering might be an issue, let the soil around the tree dry out for a few days before watering again. A third possibility is that the tree has been damaged by lawn equipment such as a weed whacker or lawn mower.

This damage usually appears as browning or fraying of the leaves on one side of the tree. If this is what’s happening, there’s not much you can do except try to prevent further damage by being careful when using lawn equipment near your arborvitae. Whatever the cause of your newly planted arborvitae turning brown, don’t give up hope!

With a little care and attention, it will soon be green and thriving again in no time!

Can You Save an Arborvitae That is Turning Brown?

Your arborvitae may be turning brown for a number of reasons. It could be due to drought, poor drainage, compacted soil, or damage from chemicals or salt. If you think your arborvitae is turning brown due to one of these reasons, you can try to save it with some simple steps.

Drought: If your arborvitae is turning brown due to drought, water it deeply and regularly during dry periods. Try to keep the soil moist but not soggy. Mulch around the base of the plant to help retain moisture.

Poor drainage: If your arborvitae is in an area with poor drainage, try planting it in a raised bed or mound. This will help improve drainage and prevent the roots from sitting in waterlogged soil. You can also improve drainage by aerating the soil around the plant and adding organic matter such as compost.

Compacted soil: Compacted soil can prevent water and nutrients from reaching the roots of your arborvitae. To loosen compacted soil, aerate it with a garden fork or other tool. You can also add organic matter such as compost to improve its structure.

What Causes an Arborvitae to Turn Brown?

If you have an arborvitae (Thuja occidentalis) that is turning brown, it is likely due to one of several reasons. First, the tree may be suffering from drought stress. This can happen if the tree is not getting enough water, either from rainfall or irrigation.

The leaves of the arborvitae will turn brown and curl up in order to conserve moisture. If this is the case, you’ll need to water your arborvitae more frequently. Second, the tree could be infected with a fungal disease called cedar-hawthorn rust.

This disease affects both cedar trees and hawthorns, and causes orange-brown lesions on the leaves of the arborvitae. If your tree has this disease, you’ll need to treat it with a fungicide. Finally, winter damage can also cause an arborvitae to turn brown.

The cold weather can damage the leaves of the tree, causing them to turn brown and drop off. If your arborvitae has suffered winter damage, it will likely recover on its own once warmer weather arrives.

What Does an Overwatered Arborvitae Look Like?

An overwatered arborvitae looks like it is wilting and/or has yellow leaves. The leaves may also be falling off the tree. If you think your arborvitae is overwatered, check the soil to see if it is wet or moist.

You can also check the leaves for signs of stress, such as browning or curling.

What Does a Dying Arborvitae Look Like?

When an arborvitae is dying, it will often turn brown or yellow. The leaves may also be discolored, and the tree may lose its needles. If the tree is not receiving enough water, it will begin to droop and the branches may become brittle.

If an arborvitae is dying from a disease or pest infestation, the leaves may fall off prematurely and the tree may produce less fruit.

Conclusion

If your arborvitae is turning brown in the summer, it could be due to a number of reasons. It could be drought stress, which is common in areas that experience little rainfall. Or, it could be due to too much sun exposure.

Arborvitae are native to shady areas and can scorch in direct sunlight. Another possibility is that the tree is being attacked by pests or diseases. If you suspect this is the case, you should contact a certified arborist or tree care professional for diagnosis and treatment options.
