Why Your Lilac Leaves Are Curling: Why Is This?

If you have an outdoor garden, Lilac shrubs can be a great way to mix things up and make it look and smell great. You already know this.

A sign that you’ve been taking good care of your plants would also be if you keep getting the same kind of blooms year after year.

Is your Lilac bush having a hard time with its leaves?

If your plant’s leaves start to curl, that’s not a bad thing. It’s just a sign that something’s wrong with your plant and that you should pay attention.

Some of the most common reasons why Lilac leaves curl are when they get wet, have pests, or get powdery mildew.

Because of this, here are some of the problems and why they might be happening, then.


If you give plants too much water, the damage can be much worse. It can also be easy to forget to water your Lilacs.

As a result, the leaves of the shrub may curl up in an effort to keep as much moisture as possible. This is called “underwatering” or “dehydration.”

A simple answer and the simplest way to get curly leaves is what I’d look into first.

Because rot and other problems are bound to happen if you keep the soil wet for a long time, you don’t want to water Lilac trees too much.

Water Lilacs instead when the first inch or two of soil has dried out, making sure that the lower soil is still moist but not wet.

Even if you’ve been watering a lot, make sure you use soil that drains well.

Make sure your Lilac is getting enough water. If you think it hasn’t, just give it a drink.

Pests like to eat Lilac

Aphids, spider mites, and borers are some of the pests that can attack lilac plants.

These pests will eat the sap in the leaves, which will make them lose nutrients and change how the leaves look.

There are a lot of different kinds of pests that aren’t visible to us. You might see them hanging out on the stems of the plants, chewing on the leaves, or leaving behind signs like spider mite webbing.

As soon as pests start to bother your shrub, you should get rid of them. This will keep the bugs from spreading to other plants in your garden, and it will also keep the shrub safe.

Using a good quality neem oil spray can help get rid of these pests and keep them away for a long time.

There are some things to keep in mind, though. If you use the neem, try to only spray at night and let it dry so that the leaves don’t get burned by sunlight while the spray is still on them.

Once the pests are taken care of, you can just cut back any leaves that have been damaged. This will allow new growth to start.

Mildew that looks like powder

If you see spots or patches of a white powdery substance on your Lilac shrub, then chances are you have powdery mildew on your hands.

When there is a lot of humidity and not enough air movement, powdery mildew can grow.

This can make the leaves look weird and curl up, but it’s not bad and most of the time the plant can go on without any help.

If you want to get rid of powdery mildew, you can use any kind of fungicide or cut back the leaves that have it.

If you want to avoid this in the future, you can cut the shrub often to let more airflow through, or you can grow it in a more dry environment because the humidity is a big factor.
