Starting lilac suckers?
Part 1. I have a 70ft x 5 feet wide and 10ft high lilac hedge between me and the neighbor (he planted 30+ years ago, and he has now passed so I cant ask how he did it). We want to do the same thing in the back of our yard. It would be bout 80 long. How far apart would would I plant the suckers apart to make a nice hedge, and how big should the suckers be to plant?
Part 2. I have a 50ft by 4 ft raspberry garden there now how would you kill the raspberries off? I heard round up if I use that how long do I have to wait to plant the lilacs?
