These tubers were planted in a really crowded flower bed - right next to other tubers and a lot of Gladioulus but they are thriving. All 4 tubers are growing into small (approx 6) but beautiful plants. The flower bed was prepared with peat moss, soil and cow manure and compost, and is watered almost everyday. I did not put Preen around the tubers after planting and I noticed a few Poison Ivy after a few days. I planted these on the weekend of the 4th of July and although I do not see any buds yet, there is a lot of foliage and I am looking forward to their blooms.
