If your lilac leaves are curling or turning brown, our yard expert can help you figure out what’s wrong. Also, find out if deer eat lilacs.
Lilac Leaves Affected by Disease and Drought
“The leaves on my lilac plant turn brown, making it look like it’s dying. At first, the plant is green and healthy.” It looks good again after a couple of weeks. During the summer, the process happens three or four times. “What’s going on?” The speaker of Birds & Blooms is Robert Snyder
Melinda Myers, a gardening expert: Those signs might be a reaction to times of drought. During the growing season, pay close attention to the lilac leaves and keep an eye on the amount of rain and watering to see if there is a link between the two. A lack of nutrients can also make leaves turn different colours. Usually, it shows up in a certain design or part of the plant.
Getting your soil tested will help you figure out what kind of fertiliser you need if this sounds like an option. When the earth is too wet or too dry, it can also lead to a lack of nutrients. In these situations, the plants can’t get nutrients from the dirt. If this is the case, giving it enough water will help.

Curling Lilac Leaves
“My lilac’s leaves curl up, and it’s never fully flowered.” “What could be wrong?” Sarah Hartzell, a Birds & Blooms fan
Melinda: Bacteria can cause lilac blight, which can make leaves curl. On the leaves and new stems, brown spots or sores may show up. The only way to control it is to cut off infected shoots below the diseased part. Between cuts, make sure to clean your tools with vinegar or a disinfectant spray.
Curled leaves that are green and free of spots could mean that the roots need more or less water. To get deep roots, try watering less often and more carefully. If you don’t give the lilac enough sunlight, too much fertiliser, or pruning before or after the flowering season (when it should have bloomed), it might not bloom again the next year.
Do Deer Eat Lilac Leaves?
“Three of my five lilac bushes have leaves that are lost or worn off.” I read that deer stay away from lilac, so what could be making them do that?” —Birds & Blooms fan Beverly Calderoni
Melinda: No plant is completely safe from deer. When deer browse, they tear plants apart, leaving behind torn tissue. But rabbits’ teeth are very sharp and can cut through things cleanly, like a bypass pruner. Most of the time, they have to be less than 3 feet from the ground to eat leaves. Some squirrels may rip off the bark and leaves at the same time.
Some animals might be scared away by scare methods, but most animals in cities and suburbs are used to seeing people, so this is not as effective. You might want to use a repellent like Plantskydd that says it can keep deer, foxes, and rabbits away and won’t get damaged by rain or snow. That way, you won’t have to apply as often.
