Hello! Our home was built in 1973. We just moved in last year. There is a lovely lilac 'tree' growing in the SE corner of the side yard. This is not a bush, but has been pruned to be a tree and is about 15 feet tall. Knowing nothing about lilacs I planted ferns and hostas underneath. They are doing well - but I battle continuously with the lilac suckers! My question: transplant the ferns and hostas and allow the lilac suckers to grow into . . . . ? Or, just keep on pulling them up? But won't that damage the hostas and ferns?
