Hi - we moved to a house a few years ago and inherited some very overgrown lilac bushes. I have been reading about pruning and think I have a good understanding of how to do that - my question is about one area of my yard that we recently cleared of brush and discovered many lilac plants with just one or two branches that I am assuming are suckers from an original plant (in pretty bad shape). This area of my yard would be totally fine to fill with lilac bushes - so my question is will these lilac plants grow into lilac bushes if they are in fact a product of one original lilac tree? Do I need to do anything to help this process along? Or should I cut them all back? They range in distance from what I assume to be the parent plant about 10 yards or so. Or am I totally wrong that they're from suckers and the original owner planted several bushes that just weren't thriving bc of overgrown brush?
I'm a TOTAL newbie - moved from Brooklyn and had just a balcony there. So assume a great level of ignorance when responding. Thank you for any advice you can give!!!!
