Make sure to amend your soil before adding the mulch. Lilacs grow best in soil rich in organic matter. Wait to plant the lilacs so that you can keep an eye on the soil moisture after you plant them. Add mulch after about a month when you know that the lilacs are growing well. Keep the mulch about 6 inches from the base of the stems.
