Answer: I think your new plants are simply adjusting to their new homes. It will take several weeks for the roots to become established and until then they will look a little puny. The soil may be richer than they have experienced in the past and they may be getting more moisture than they are accustomed to. Time will help them adjust. Until then, water them deeply once a week - twice a week if the weather is hot. New growth should emerge a healthy green. Best wishes with your new maples and lilac.
