Plattsburgh, NY, Feb 22, 2010 — Horticulturist Amy Ivy says she spent time this past weekend propagating a whole new generation of houseplants. Geraniums, a goldfish plant, a jade tree -- all got a fresh start. Amy, with the Cornell Cooperative Extension Service, is a true green thumb. But according to what she told Martha Foley, starting new plants from old ones isn't only for the expert gardener.
