How to Check Your Trees for Disease in Spring

During the winter months, your trees and shrubs are typically dormant meaning they won’t grow or produce new blooms until the weather warms up. This helps them preserve nutrients and can slow the progression of common diseases and pest infestations. But once the weather warms up and your trees and shrubs start to enter the growing season, you’ll want to be vigilant and watch for any early warning signs of disease before it has a chance to spread. Your Denver plant health care team is here to help. Here are a few steps you’ll want to take in early spring so you can schedule a treatment appointment quickly.

Check the Bark for Changes
When trees are diseased, it’s normal to see some changes in the bark’s appearance. You may notice pitting, holes, or even bark peeling up in places. This can also indicate the presence of harmful pests like Emerald Ash Borers, Mountain Pine Beetles, and others. 

Inspect your trees’ bark at least once a month. If you notice any changes, contact your plant health care team immediately. They’ll be able to assess the condition of your trees and determine if the changes to the bark are the result of disease.

Monitor Growth Often
Healthy trees tend to grow steadily throughout the warmer months. As the weather improves, start monitoring the growth for each tree on your property. If one is growing more slowly than others, growing in inconsistent ways, or not growing at all, call your plant health care team and let them inspect your trees for damage. Once they identify the underlying cause, they’ll be able to create a treatment plan to better protect your property.

Look for Visible Insects
Insects can damage trees directly, but they can also lead to an increase in fungal growth that hurts your trees’ abilities to produce new leaves and limbs. Check each tree on your property for visible signs of insect activity. Holes in the bark, burrow trails on the branches, and even live and visible insects are a surefire sign that you have a problem. Your plant health care team will be able to identify the pest and create a solution to help get rid of them.

Keep an Eye Out for Premature Leaf Discoloration
As the growing season starts, you should notice healthy green growth on your trees. But if you see discoloration of once-green leaves or leaves growing in yellow or splotchy, it’s likely that your tree is struggling. When caught early, your tree may be able to recover from whatever disease is affecting it so you can enjoy the same beautiful growth you’ve come to expect.

Make Sure It’s Firmly in Place
During the growing season, you’ll likely need to water your trees more often than you did during the winter months. Use this to your advantage. Every time you water, make sure the roots are still holding the tree firmly in the soil. If you notice any leaning or oversaturation in the soil, call your plant health care team immediately. 

Keep Your Trees Growing Well All Year Long
As spring weather starts to roll in, check your trees for early warning signs of disease and insect infestations. If you notice anything of concern, don’t wait. Contact Root Tree Service to schedule an assessment.
