Q.calla lily, dahlias, elephant ear bulbs
I wanted to buy bulbs left over at the nursery; they’re getting rid of them. Since it is so late in the season, I was wondering if I could buy the bulbs, store them in the peat moss and plant them next year, instead of planting them now. I hope you can help. Thank you.
