Feels odd to be asking such a basic question, but I can't seem to grow beets very well. And I do love beets. The tops look fine, and taste great, but the bottoms never seem to round out. Either they never develop at all or are conical and long. I have a couple of theories that I'd like some feedback on. 1) I'm not thinning them enough. 2) I'm planting them too late in the season (I'm in the IE in SoCal) 3) I'm not watering them deeply enough. Help and comments from those with success will be greatly appreciated. And Happy Father's Day to all the gardening dads!
