Do you ever look at one of the trees in your yard and notice small, raised areas on the foliage? Experts at East Coast Arbor Pro can answer this common question, “What are the bumps on leaves that appear?” Discover what causes the bumps, how they affect your tree’s health, and whether you need tree removal in Vero Beach, FL, for this issue.
Understanding Leaf Galls
When you get a mosquito bite or a pimple, it leaves a bump on your skin but tends to go away. However, if you break out in hives or have several bumps on your skin, it often signifies something more serious that needs immediate attention. The same logic applies to leaf galls.
These raised spots on leaves can appear on trees in Vero Beach sporadically or take over the entire structure. A few galls don’t pose significant concerns, but if they overwhelm a tree, it’s time to contact a professional arborist.
Common Causes of Leaf Galls

Insects
Several types of insects feed on leaves and cause minor injuries to the foliage. The affected leaf responds naturally by forming galls. However, the bumps usually appear long after the injury takes place and the insect moves on. Property owners typically see an influx of leaf galls after harsh winters leave trees especially vulnerable to leaf-feeding insects.
Fungi
If you don’t take proper care of your trees, you risk fungi like mold and mildew growing at the base of your tree. For example, if you struggle to get grass to grow beneath your tree and overwater it, the moisture can sprout fungi. This can ultimately lead to leaf galls that weaken your structure over time.
Take precautions like giving the grass under trees a set amount of water and don’t increase the amount if the grass seed fails to sprout.
Worms
Nematodes in your soil can rob the tree of nutrients and weaken it over time. Just as when leaf-feeding insects take hold, the tree responds to this injury by growing bumps on its foliage. Watch out for galls that overtake large trees with no obvious pests or fungi around, as this can be the result of underground worms.
How To Address Leaf Galls
You now know the answer to the question, “What are the bumps on leaves?” but are probably still wondering what you can do about them. Spotting only a few bumps isn’t a big deal but contact an arborist if the problem appears to be widespread. Experts will assess the tree’s health and recommend solutions such as:
- Pesticide application
- Fertilization
- Pruning
You can take matters into your own hands by spraying dormant oil on your foliage as it begins to bloom in early spring, as this deters insects from feeding. In severe cases, the tree’s structural integrity becomes compromised due to extensive decay and injury. The only way to keep your property safe is to remove the hazardous tree.
