Carolina Sapphire Cypress Turning Brown? Here’s Why & How to Save It

The most common cause of browning Carolina Sapphire Cypress is overwatering. Carolina Sapphire Cypress prefers low, steady moisture levels and should be watered deeply but infrequently. If you notice your tree is turning brown, check the soil to see if it feels wet all the way down to the root ball, and if so, water less frequently.

The Carolina Sapphire Cypress is a popular tree with a pretty blue-green appearance. Many people choose this tree for their homes as well as in commercial landscaping. In this article, I am going to share with you what causes the browning of Carolina Sapphire Cypress trees and how to save them from dying.

Why Is My Carolina Sapphire Cypress Turning Brown?

Browning is a sign of stress. It can be caused by environmental stress, improper watering, cold weather damage, nutrient deficiencies, experimenting with fertilizers and soil products and disease.

Environmental Stress

Carolina sapphire cypress grows in the southwestern United States, where it is threatened by a number of environmental stresses. The tree’s leaves turn brown when it is under stress from drought or cold weather.

In the wild, Carolina sapphire cypress trees grow in dry, sandy soil in coastal areas of Mexico and Arizona. These trees are adapted to withstand periods of drought and can survive for long periods without water.

In fact, they can actually take advantage of dry conditions and grow more quickly than normal when there is less water available to them. However, when they are stressed by prolonged periods without water or cold temperatures, their leaves will turn brown and begin to drop off.


Carolina Sapphire Cypress is a great choice for your landscape because it’s very easy to grow, doesn’t need much attention, and has beautiful blue-green needle like leaves. It’s also tolerant of most soil conditions, including clay and poor drainage, which makes it a great choice for planting in areas with poor drainage or clay soils.

But one thing that can cause Carolina Sapphire Cypress to turn brown is overwatering. If you water your Carolina Sapphire Cypress too much, the roots will rot and die, causing the plant to turn brown or even die completely. You should water your Carolina Sapphire Cypress when the top inch of soil feels dry usually once every 2-3 days during spring and summer months and then once a week during fall and winter months when temperatures are lower and more moisture is needed.

Too little light

One of the most common reasons for Carolina Sapphire Cypress turning brown is a lack of sunlight.

Carolina Sapphire Cypress is a tree that loves the sun, and it needs lots of exposure to produce the vibrant blue coloration in its needles (the needles are what make this plant look like a Christmas tree). If you don’t give your Carolina Sapphire Cypress enough light, it will start to turn brown. This is because it’s spending too much energy trying to photosynthesize, and not enough energy producing chlorophyll.

The good news is that if you’re experiencing this issue with your plant, it’s easy to fix! Just increase the amount of light exposure that your tree gets on a daily basis. It should be planted in an area where there is at least six hours of full sun each day and not blocked by other objects or plants.

Overcrowding of plants

When plants are overcrowded, they tend to grow more slowly and their leaves will turn yellow or brown. This is because the plants are not getting enough sunlight, water, or nutrients. It is important to keep your plants at a good distance from each other so they can get plenty of light and water.

Cold Weather Damage

Cold weather can be brutal on the Carolina Sapphire Cypress trees. The cold temperatures and heavy snowfall can cause branches to snap, which can lead to major repairs or even entire tree removal.

If your area has experienced heavy snowfall this winter, chances are good that some of your Carolina Sapphire Cypress trees have been damaged by heavy ice accumulation.

Luckily, Carolina Sapphire Cypress trees are pretty resilient, so most of them will recover from these types of damage without much effort from you at all.

Nutrient Deficiencies

Carolina sapphire cypress trees are fast-growing evergreens that are naturally prone to nutrient deficiencies. They respond well to granular fertilizer that can be applied in spring, summer and autumn.


It’s important to note that the Carolina Sapphire Cypress is resistant to many diseases and pests, but it is still susceptible to some problems.

Canker disease

Canker disease is often caused by a type of fungus that affects plants in the Cupressaceae family. It’s most common in junipers, but it can also affect Carolina sapphire cypress and other species of cypresses. The disease causes brown spots to form on the leaves and stems of affected plants, which will eventually turn yellow or brown and fall off.

The best way to protect your plants from this type of fungal infection is to make sure they have plenty of sunlight and water during hot summer months (when they’re most likely to get sick), and to avoid overwatering them during cooler seasons. You should also inspect your plant regularly for signs of trouble for instance, if there are insects feeding on it or if the leaves are curling up in an abnormal way and remove any dead growth immediately so that it doesn’t spread further into healthy parts of the plant’s ecosystem.

Needle Blight

The needle blight caused by Cercospora sequoiae is one of the many reasons why Carolina Sapphire Cypress trees are turning brown.

The needle blight is a disease that affects the needles of Carolina Sapphire Cypress trees. The disease is caused by a fungal pathogen called Cercospora sequoiae. The needles turn brown and become brittle as they die, and eventually fall off the tree. This can cause significant damage to the tree’s overall health, which may cause it to die.

The disease can be spread through contaminated soil or tools used to prune infected plants, so it’s important to clean your tools after working with diseased plants in order to prevent further spread.

If you notice that your cypress is browning as a result of disease, prune away any infected branches immediately. You can use pruning shears or a saw to cut off the infected parts of your tree.

If there are leaves that are dead from disease on your tree, you can also use a garden hose to wash them away. If diseased leaves have fallen off and landed on the ground, remove them by hand. If possible, spray pesticides directly onto these fallen leaves in order to prevent additional spores from being released into the air.[su_youtube url=”” width=”500″ height=”360″]
