Q.Will adding more soil around an existing lilac bush harm it?
I am building a raised flower bed around and older lilac bush and was told that adding more soil will kill the lilac bush. Will this harm or kill my lilac bush?
When we first moved into our home in town, two lilac bushes had portions of their root systems poking up through the ground surface. I cover the areas with 6 to 8 inches of new amended soils and they did just fine. So adding more soils for your raised flower beds should not be a problem.
