Sounds like a lot of soil needed to pile into the box. Sure it's somewhat gradual, but once done and harvested, you still have a lot of dirt to deal with.

Larry - If you want to hill the potatoes, you can also use straw. That is what I used the last time that I grew them in fabric bags. But from what I understand only late potatoes benefit from this practice and not the early varieties like Yukon Gold. It is good to keep the potatoes covered because you don't want them to get green exposed to the sun. If the raised bed is deep enough, they will have enough room to expand. If you plant them now and we have a frost, they will survive if you cover them in cold nights.

Thanks Silvia. I got Canela Russet and Russian Fingerling. Both are 100 day varieties. I was planning to raise the bed with a combination of straw and compost/soil. Hopefully the straw will break down some and I can use it as make-up dirt for my other beds when the potatoes are done. The sand dune I'm living on can use all the organics I can throw at it.
