The Carolina Sapphire Cypress is a beautiful tree that can be found in the southeastern United States. It is known for its dark green leaves and blue-gray bark.
Unfortunately, many people are noticing that their Carolina Sapphire Cypress trees are starting to turn brown. In this blog post, we will explore the possible reasons why this is happening and how you can save your tree!
Why Is My Carolina Sapphire Cypress Turning Brown?
Overwatering, insect damage, fungal disease, and leaf burn are the most common causes of your Carolina Sapphire Cypress browning. The type of browning will help to identify the problem.
For example, if the leaves are brown and moist, it is most likely due to overwatering. Whereas if the leaves are brown and dry, it is most likely due to leaf burn. If the leaves are brown and have holes in them, it is probably due to insect damage.
I will now go over each of these problems in more detail and offer solutions on how to fix them.
1. Overwatering
The Carolina Sapphire Cypress is a drought-tolerant tree that does not need a lot of water. In fact, too much water can be harmful to the tree. If you are watering your tree more than once a week, it is likely that you are overwatering it.
To fix this problem, cut back on the amount of water you are giving your tree. Water it only when the soil is dry to the touch. If you live in an area with a lot of rain, make sure to drain any excess water from the roots of your tree.
The roots could be waterlogged, which is preventing the tree from getting the oxygen it needs. in fact, this can even cause root rot that will kill your tree.
If you think your tree has root rot, it is important to act quickly. Remove the tree from the ground and replant it in fresh, well-draining soil. You should also water your tree with a fungicide to help prevent the spread of disease.
If you think that overwatering is not the problem, continue reading to learn about other possible causes of browning.
2. Leaf Burn
Leaf burn is a common problem with Carolina Sapphire Cypress trees. It is caused by the tree getting too much sun or wind. The leaves of the tree will start to turn brown and dry out. This is especially common in areas of the country that have hot, dry summers.
To fix this problem, you can try to move your tree to a shadier spot. If that is not possible, you can also try to water your tree more often. This will help to keep the leaves from drying out.
You should also make sure that you are not using any chemicals on your tree that could be causing leaf burn. If you are using fertilizers, herbicides, or pesticides, switch to organic products.
3. Pests
Many different types of pests can cause problems for your Carolina Sapphire Cypress. Aphids, scale insects, and mites are all common pests that can infest the tree. These pests suck the sap out of the leaves, which causes them to turn brown and die.
To get rid of these pests, you can use a variety of methods. You can try to remove them by hand or with a hose. You can also use insecticidal soap or horticultural oil to kill them.
If you have a serious infestation, you may need to call a professional pest control company. Personally, I’ve had good success with neem oil (Amazon link), but there are many different products on the market that will work.
4. Fungal Disease
Fungal diseases are another common problem with Carolina Sapphire Cypress trees. These diseases are caused by fungi that live in the soil. They can attack the roots, trunk, and leaves of the tree.
Some common fungal diseases include root rot, powdery mildew, and leaf spot. These diseases can cause the leaves of your tree to turn brown and die.
To prevent these diseases from happening, make sure the garden is clean and free of debris. You should also water your tree at the base, not from above. This will help to keep the leaves dry and prevent fungi from growing.
If you think your tree has a fungal disease, you can treat it with a fungicide. There are many different products on the market. Again, neem oil is an effective fungicide that I’ve had good luck with.
Will Brown Carolina Sapphire Cypress Leaves Turn Green Again?
No, it is unlikely that brown leaves on a Carolina Sapphire Cypress will turn green again. Once the leaves have turned brown, they are dead. You can remove them from the tree to tidy it up, but they will not grow back.
The good news is that new growth will eventually replace the dead leaves. If you take care of your tree and give it the proper care, it will continue to thrive for many years.

Should I Remove Brown Leaves from My Carolina Sapphire Cypress?
There’s no need to remove brown leaves from your Carolina Sapphire Cypress unless they are interfering with the new growth. If the brown leaves are at the bottom of the tree, they will eventually fall off on their own.
However, you can tidy up your tree by removing any dead branches or leaves that are hanging down. This will help to improve the tree’s appearance and allow it to focus its energy on new growth.
Conclusion
In conclusion, brown leaves on a Carolina Sapphire Cypress are usually caused by one of four things: too much sun, pests, fungal disease, or leaf burn.

Hi, I have a Carolina blue sapphire.and had an live in loisville ky. And this past January we had a below zero cold snap. The leaves on the entire tree are brown, but the trunk and branches are still green. Should I leave tree alone, and wait till spring to see what tree leaves do. Or wait till spring and cut all of the brown
Leaves off. Also have some Leylands that are close to the street that have brown leaves on the street side. Should I leave alone an the warmer weather will bring them back out. Have a good one, Thank you for your feedback.
For your Carolina blue sapphire, since the trunk and branches are still green, there’s a good chance that it’s still alive. I would recommend waiting until spring to see if any new growth emerges. During this time, you can monitor the tree closely to assess its condition. If the brown leaves persist and new growth doesn’t appear by spring, you may need to consider pruning off the dead foliage to encourage new growth.
As for your Leyland trees, if the brown leaves are only on the street side, it’s possible that they were exposed to harsh conditions like road salt or pollutants. In many cases, Leyland trees can bounce back with the arrival of warmer weather. I would suggest waiting until spring and monitoring them closely. If the brown leaves don’t improve or if there’s no new growth by then, you can consider pruning them to encourage healthier growth.
