I had 3 that I planted a week ago, they didn't come up yet - I wasn't worried, but I wanted to double check them. The Columbus I had planted waaaaay too deep, I kept digging and digging before I finally found it about 6-8 inches down. It was my healthiest rhizome (had probably a dozen shoots on it), so I dug it back up and re-set it about an inch from the surface. Even still, the shoots had grown a couple inches toward the surface. I started to check on the magnum but only got about an inch down when I found a shoot with a green top. That'll break the surface in the next couple days. The third one (Mt. Hood) was a little deep also, moved it up to an inch or so from the surace.
I expect all three will break the surface by the end of the week. Planning to get a trellace setup later this week.
