I bought 2 topiaries for my front porch this summer. I potted them. They did wonderful. With winter approaching I brought them into my dining room because I don't know what kind of plant they are. They have small waxy leaves. One had little white flowers this summer. Fell off after a couple weeks. The other no. They hate the inside and are drying up because of the heater I guess. Gave them water. Losing leaves. Should I take them outside again or will the die in the cold? They are not evergreens. Help. Don't want to throw them away. Should I fertilize them? Not root bound.
