Lilac bushes are generally pest and disease resistant, but they can be affected by lilac leaf mining moths or thrips, which don't usually harm the plant's vigor.

Aphids, powdery mildew, and lilac borers are common lilac adversaries that can cause significant damage if left unchecked. Regularly inspect the leaves for any signs of trouble and address the issues promptly.

Leaf spot diseases, caused by various fungi, lead to the appearance of dark spots or lesions on lilac leaves. These spots can merge, causing the leaves to turn yellow and drop prematurely, weakening the plant.

Powdery mildew is a common fungal disease affecting lilac bushes, creating a powdery, white substance on the leaves. This unsightly occurrence not only mars the lilac's appearance but also weakens its ability to photosynthesize effectively.

To combat powdery mildew, ensure proper air circulation around the plant by pruning the lilac to allow air to flow freely through the branches. Watering the plant at the base early in the day can also prevent the foliage from staying damp, discouraging the fungus growth.

Root rot, a fungal disease caused by overly wet soil conditions, can seriously threaten lilac bushes. To prevent this issue, ensure the planting area has well-draining soil and avoid overwatering, especially in poorly draining soil.
