Why is evergreen turning brown

Solution: You can try an anti-desiccant spray to help with the dryness. Problem: Evergreens attract a few common pests and diseases, like the pine beetle or cytospora canker disease. Browning needles can be a symptom of infection, along with small holes, sawdust or large cankers leaking white sap on branches. Solution: We recommend you call in an arborist to figure out a course of action. An anti-desiccant is a waxy coating sprayed on plants to shield them from moisture loss.

Applying the film in winter is said to safeguard trees until spring. For best results, we like to wait until the temperature drops to degrees F. Using the anti-desiccant in the right elements at the right time is essential to avoiding tree damage. Our technicians do one or two rounds of spraying the formula on dry needles in winter to help plants reduce moisture lose. Usually, these happen anytime between November and February, but your arborist will talk to you about what's right for your tree.

Then, your tree will be good to go for the season!

Winter weather woes Problem: Winter elements are notoriously tough on trees, but evergreens are especially vulnerable. Sunny days Problem: Take the already dry winter and add in the beating sun—now your tree has even thirstier needles.

An infecting intruder Problem: Evergreens attract a few common pests and diseases, like the pine beetle or cytospora canker disease. If you think this is the case, you can break up the soil and try to rehydrate. Often, browning will start in one small area and then quickly spread to the rest of the tree. If you catch it early, you might be able to clear everything simply by pruning the part away.

However, you will often have to go deeper. One of the most common diseases for evergreen trees is root rot. With this disease, you will see brown, wilted needles and sores running along the root system of the tree. Root rot is a fungus and can be quickly cleared by moving any damp soil away from the roots and allowing them to dry, according to Fort Collins Nursery. Another common problem for evergreen trees is rust. This is another fungal disease that causes powdery spores on the needles.

You have to prune the tree and remove every infected needle to clear it — which is why we suggest contacting a professional to limit the stress put on the tree. Evergreen browning can be caused by weather conditions. Too much rain can lead to root rot that will open your trees up to other issues. In general, browning is just a cry for help from your trees. This is often called dessication or leaf burn. Thorough watering from late summer through fall and topping the root zone of the evergreen with mulch can help avoid winter browning from dessication.

An evergreen tree, on the other hand, does not have that same ability. Once the needles or fronds turn brown, they stay brown.

Depending on the cause of the browning, an evergreen may be able to generate new growth from the tips, but sometimes the tree ends up looking like a tree made up of bottle brushes.

Many arborvitae trees succumbed to the drought of Once that species of evergreen begins to turn brown, there is not much you can do to save it. We had numerous reports of arborvitaes dying throughout the drought areas in Unfortunately, there is no amount of tree care that can bring those trees back.
