The calendar says that spring is here; unfortunately, Mother Nature has had other ideas. So while the snow dissipates and the ground thaws, you can begin potting up your tubers in preparation for taking cuttings – or for later planting in the ground.
While a greenhouse is nice, you don’t need one in order to take cuttings. A table with a fixture or two of inexpensive fluorescent lights hung over the table is sufficient. Make sure the lights can be adjusted so the plant growth is no more than 3- to 4-inches from the light; otherwise the plant will stretch.
Use a good peat-based potting mix that is damp (not wet) and pot the tuber so the eye is sitting just above the medium. You can bury the tuber, but you will have to move the medium aside to cut the stem close to the tuber. Cutting can be done when the plant has 2 sets of leaves. Using a disinfected blade or scalpel, cut the plant away from the tuber. Remove the bottom set of leaves and place the cut stem in the potting mix. You can use a rooting hormone if you wish, but it is often not necessary. Rooting should take place within 2 to 3 weeks, depending on the variety. This is a good way to increase your stock.
Another way is to come to the RIDS tuber sale on May 6th at 1:00 at the Cold Spring Community Center, North Kingstown, RI and pick up some of the beautiful varieties that will be on sale. Over 100 named varieties from giants to miniatures will be available. All tubers are reasonably priced.
