I only found out a few weeks ago that digging oyster shells into the dirt will help with tomato blossom rot, which my tomatoes get.
Hard to see here but I did sprinkle some oyster shells in...
I watered them and then covered them with some plastic using some tent poles Art found in a dumpster..
Art wrapped some stakes on the long sides of the plastic and secured them with staples, this will keep the plastic in place keeping my tomatoes warm and dry. Luckily Art had the plastic on hand, recycled from something else so these makeshift greenhouses were free, and that's very good.
