I planted two last week as well, one large willamette and one "twig" of a cascade. Getting panicky that i planted in the wrong soil ( MG veggie soil) i dug them up and replanted in potting soil. The cascade that came almost budless had 3 good strong buds forming and the Willamette had one inch long bud starting to sprout. Long story short, repotted on Monday, Willamette broke soil yesterday (wednesday) and cascade has not yet only because it is a much smaller rhizome than the other. I've only been watering about every 2-3 days as i don't want to drown them. From what i've read give them about 1-2 weeks on average to sprout, i wouldn't dig up until then.
