The bald cypress tree is a hardy plant with a fighting spirit that can thrive in USDA Agriculture plant hardiness zones from 5 – 10. Most gardeners and horticulturists will find that this tree is easy to take care of and rarely runs into plant problems involving pests, fungal diseases, and environmental conditions. If your bald cypress plant is not thriving, find out why your bald cypress tree is turning brown.
Bald cypress trees are beautiful additions to any landscape, but like all trees, they can be affected by diseases. One common disease is blight, which can seriously impact the health and appearance of these trees. In this article, we’ll discuss what blight is, how to identify it on bald cypress trees, and most importantly, the steps you can take to get rid of blight and restore the health of your tree.
What is Blight?
Blight refers to a range of fungal diseases that affect plants, including bald cypress trees It is often caused by pathogens like Seiridium cardinale The most common type of blight in bald cypress is known as cypress blight or Seiridium canker. This fungal disease causes cankers, dieback of branches, and foliage problems.
Blight thrives in wet humid conditions. If left unchecked it can spread rapidly through the tree and eventually kill it. That’s why it’s crucial to identify blight early and take prompt action.
How to Identify Blight on Bald Cypress Trees
Here are the most common symptoms to look out for:
-
Leaf spots: Small, dark spots appear on the foliage. The spots may merge and turn brown, causing leaves to drop.
-
Falling leaves: Premature leaf drop, sometimes with discolored or spotted leaves.
-
Dieback: Tips of branches turn brown and die. The dieback spreads through the branches over time.
-
Cankers: Sunken, discolored areas on branches and trunk. Cankers disrupt nutrient flow.
-
Fungal growth: White/gray fungus visible on bark.
Carefully inspect your tree, especially after damp weather. Check for abnormalities in the foliage, branches, and trunk. Look inside the canopy for inner symptoms. Catching blight early makes treatment much easier.
How to Get Rid of Blight on Bald Cypress Trees
If you suspect blight, take action ASAP. Here are effective treatment methods:
1. Prune Infected Areas
Pruning is the first line of defense. Remove all branches with signs of blight. Cut at least 6 inches below visible disease. Sterilize tools between each cut to avoid spreading spores. Destroy the infected trimmings.
2. Apply Fungicides
Fungicides that contain active ingredients like copper, mancozeb, or chlorothalonil can treat cypress blight. Follow label directions carefully. Time applications to protect new growth. Repeat on a 7-14 day schedule as needed.
3. Improve Air Flow
Promote good air circulation through the canopy. This creates an environment unfavorable for fungal growth. Properly space trees when planting. Thin inner branches to open up the canopy.
4. Support Tree Health
Keep your bald cypress vigorous to resist infection. Water and fertilize appropriately. Avoid excess irrigation. Manage pests like cypress bark beetles that can weaken trees.
5. Clean Up Debris
Rake up and dispose of all fallen leaves and debris around the tree. This removes a source of spores that can reinfect the tree. Avoid wetting the foliage when watering.
6. Consider Replanting Resistant Varieties
Some cypress varieties have genetic resistance to blight. ‘Cascade’ and ‘Shawnee Brave’ are two options. Replant with one of these varieties for maximum blight protection.
Preventing Cypress Blight
Prevention is the best medicine when it comes to blight. Here are tips to avoid problems in the future:
-
Select a sunny, well-draining site to plant your bald cypress.
-
Space trees properly to allow air movement between canopies.
-
Water early in the day so foliage dries quickly. Avoid overhead irrigation.
-
Monitor weekly and treat any problems early.
-
Boost tree health with proper fertilization and pruning.
-
Remove leaves, twigs, and other debris from around the tree.
With quick action and good cultural practices, you can get rid of blight on your bald cypress tree. Stop this harmful disease in its tracks and keep your landscape looking lush and healthy.

What causes needle blight on Leyland cypress trees?
Needle blight is a disease caused by a fungus known as Passalora sequoia. This fungus usually attacks young Leyland cypress trees that are a year or a few years young. But, today, this fungus has evolved to attack even mature Leyland cypress trees. At first, the Leyland cypress leaves will assume a light-brownish look.
How do you harvest a bald cypress tree?
Collecting Seeds: Harvest mature cones from established bald cypress trees in the fall when they are fully developed but have not yet opened. Extracting Seeds: Allow the cones to dry for a few days until they open naturally. Remove the seeds from the cones and separate them from any debris.
