My Virtual Lilac leaves are curling and some leaves are burnt at the ends.

Curling leaves and crispy edges are often a sign of not enough water. Since it is mid-September, you don’t need to worry about the lilac dying. Just give it a good soaking, at the base and not on the leaves. As we get closer to winter, it will be important to prepare and protect your lilac during the cold and sometimes dry winter months. Our preparing your plants for winter guide has great tips including winter watering.
