Choose an appropriate location. Lilacs prefer a sunny location with well-drained soil in an elevated area. Site selection is very important for proper growth.
Cut part of an existing lilac bush to start a new plant. Clip a well-developed root that is attached to the main bush and has shoots that are 1 or 2 feet tall. A good root system helps to ensure your new plant thrives. So take as much root as you can.
Dig a hole twice as big as the root system you clipped to allow easy root expansion.
Add compost to your soil. Lilacs love humus-rich soil.
Plant three to five lilac shoots together.
Tamp down the soil firmly using your shovel or boots, adding more soil as needed.
Water the lilac bush regularly the first three to four weeks to help roots re-establish themselves.
