I have bought mums every year for a long time. I wouldn't mind this if I could get them to come back each year. Someone said that I am not planting them deep enough. Is this right? Also, I want to leave them in pots so can I bring them in for the winter and save them?
I have 6 year old lime and lemon trees in pots that I bring in my back patio during winter but I wonder if I could plant them in ground instead of bringing them in because they are getting big and heavy. How do I keep them from freezing?
