transplanting and moving plants
Transplanting lilac bushes is a fairly straightforward process. It is very similar to the act of transplanting most other bushes or shrubs. Transplanting lilac bushes should always be done in the autumn months. Transplanting lilac bushes in warmer, windier weather will increase the likelihood of the root system drying out. The first step is to dig around the plant and fairly deep. The underground root structure of a lilac bush can sometimes get pretty large, and it is important not to damage any roots if possible.
Once the plant is up, remove much of the soil from around the roots
