Common Reasons for Leafless Branches in Your Tree Canopy
Examining the appearance of all tree parts can give you a better idea of the vegetation’s overall health. Abnormal foliage provides helpful insight into the tree’s health. Whether the leaves turn colors when they’re not supposed to or begin to wilt and fall, you can’t ignore the signs of an ill tree.
Check out the top reasons why a tree canopy would start to lose leaves.
Drought
Instead of asking yourself, “How come the top half of my tree has no leaves?” ask yourself if your tree is receiving enough water. Drought can wreak havoc on tree and plant health by first impacting the roots and then other parts of the tree. The soil beneath your tree needs a sufficient amount of moisture to thrive and help the roots grow.
If the roots don’t get enough water, the rest of the tree will suffer the consequences. Since the canopy is the furthest distance from the roots, it will experience the effects of drought the worst, hence the leafless branches.
Nutrient Deficiency
Tree roots need plenty of moisture but they also need adequate nutrients within the soil. If the soil lacks key nutrients, the roots won’t thrive and the tree may start to lose leaves from the top down. The nutrient deficiency could stem from two separate issues:
- Improper soil: The soil could be the source of the problem upon testing.
- Girdling roots: Your tree’s roots may wrap around each other and make it harder to absorb moisture and nutrients.
If you suspect the top half of the tree has no leaves because of a nutrient deficiency, contact a local arborist to investigate.
Insect Infestation
Watch out for pests along the tree bark. Many unwanted insects feast on this part of the tree though some can migrate to the top of the tree and destroy your foliage.
Tree Diseases
Tree diseases quickly ruin vegetation and leave you with decaying, unsightly trees. One particular fungal infection that affects the tops of trees is called verticillium wilt. If your tree receives ample sunlight, water, and nutrients but the foliage suddenly drops on one side of the tree or near the top, reach out to a local arborist for a consultation.
What To Do If the Top Half of a Tree Has No Leaves
Once you determine the reason for your loss of foliage, it’s easy to figure out the best course of action. Discover common recommendations arborists make for resolving this issue below.
Water the Soil
You can’t control Mother Nature and end a drought whenever it starts to affect your plants. However, you don’t need to rely on rain for your tree canopy to appear full and vibrant. Make sure you water the soil around your tree if you start to notice changes in its appearance.
This is especially important if you live in a dry climate or go for long periods without rain. Be careful not to overwater the tree as this can have adverse effects.
Apply Fertilizer
Your tree might not look healthy and full because it’s not receiving the proper nutrients. Applying fertilizer around the base of the tree can help replenish the roots and promote healthy growth. Contact a tree service company that can test your soil and pinpoint the nutrients it lacks.
Experts will use the test results to concoct a custom fertilizer that takes care of your tree’s health issues. Opting for a generic fertilizer may not solve the problem so you end up wasting money.
Pest and Disease Management
While it helps to have an arborist to conduct soil testing, you definitely need professionals if pests or fungal infections are the reason the top half of your tree has no leaves. Certified arborists can identify the pests or tree diseases impacting your vegetation and provide solutions, such as:
- Applying pesticides
- Using fungicide applications
- Monitoring tree health going forward
You can restore your tree’s health as long as you’re proactive about eradicating the infestation and disease. No one is better equipped at this than professional arborists.
How To Enhance Tree Health
If the top half of a tree has no leaves, you can use this information to pinpoint the culprit and come up with a long-lasting solution. Caring for your property’s trees goes beyond these measures, however. The following tips will help your trees remain healthy over time:
- Prune overgrown branches regularly
- Be mindful of changes in trunk shape or bark appearance
- Fertilize the soil and apply mulch to retain moisture
- Recognize the signs of tree decay
Pruning your trees every year not only helps them look nicer but it also eliminates safety hazards from overgrown branches and promotes healthy growth. Using mulch around the tree’s base prevents the harmful effects of drought because the material keeps moisture inside the soil. Finally, understanding the signs of tree decay, including changes in the bark, means you can act quickly to reverse the effects.
