I dug out someone's large lilac tree by mistake
I really need help! I am redoing an overgrown garden in my co-op and I decided to dig out a few huge plants that were left behind by the previous owner. I dug out a plant/tree and threw it away and then found out someone really liked it and it is a lilac tree. I have retrieved it and need to know if I can replant it and what steps I should take or is it a lost cause? HOpefully someone can advise me.
