My family loves rhubarb, but we can't get it to grow large enough to harvest in our yard. It's the strangest thing, since it seems to grow like a weed for everyone else. We've tried fertilizing, both liquid and manure, making sure the roots aren't too wet by putting them in a raised bed. This has been going on for something like 20 years. Neighbors down the road have lovely rhubarb. Has anyone heard of anything like this? Any ideas besides more fertilizer?
