: I have a lilac bush planted on the northeast corner of my house. It has been there two years. This year it has a white dust or powder on it's leaves. It almost looks like mildew. What can I do to get rid of it?

Hi Theresa,

Your lilac has powdery mildew. You will need to spray with a horticultural oil in the spring. Clean up all fallen leaves this fall. When you water, water at the base of the plant. Often this comes from drought, even though it's called mildew. Give your lilac a cup of lime on the soil and scratch in. They like a more alkaline soil and will bloom better for you.

Here's a site with a recipe for your own sprays. Use one with oil in it for the lilac in the spring.

Good luck,
