The Q&A Archives: Deadheading Edelweiss

Question: Is it necessary to deadhead Edelweiss? If so, is it done when the inner part turns from yellow to brown?

Answer: Deadheading is done to prolong bloom periods especially for annual flowers, which can bloom throughout a season. The goal is to prevent the plant from expending energy going to seed. Perennials, including edelweiss, typically have shorter bloom periods, so deadheading is more a matter of "cosmetics" (to keep the plants looking neat), not necessity. (Edelweiss blooms approximately June - July, depending on local conditions.) It may help to prolong the bloom period somewhat. Edelweiss is short-lived, though, and it's more important to divide and replant it every couple of years to maintain its health and good looks. You may want to save your energy for that project!
