hollyhock and other tubers
I just got a ton of bagged Hollyhock tubers (or corms, or whatever) from costco. Also got from there Echinacea, liatris, and others.
Question: before I plant these (maybe next weekend, when it's warmer), should I soak the corms/tubers/whatever in water for some time before putting them underground? if so, how long should they soak?
