There are certain factors to keep in mind when planting lilacs.

The first thing to take care of is the location. Choose an area that receives plenty of afternoon sun along with a well-drained water system. Lilacs favor good drainage; planting them slightly on an elevated surface is always recommended.

After you plant the bushes, water them deeply and add an extra layer of mulch. Try planting the lilacs in an area that receives at least 6 hours of continuous sunlight every day.
