Lilac bush

Asked June 18, 2016, 11:36 AM EDT

I would like to know if i can transplant lilacs near my drainfield. I have a large row on another part of my property and thought about transplanting some. I live in very sandy soil and would like to use it as a windbreak. How far away should i plant them and is there a issue of them seeking out and wreaking my drainfield.
Thank you

You probably could plant the lilacs but the problem is their root system. They sucker and spread quite rapidly. Use plants that do not like water or wet soils near the septic system. This will prevent their root systems from interfering with the septic system. The larger the plant, the more extensive (not necessarily deeper) the root system.
