Once a soil test (county extension agent) reported low boron in our garden. It explained the distorted radishes. Since then we've used a lot of compost and cover crops and things are fine. But we have a small patch of strawberries off in a different place and they are small and gnarled in a way that some have diagnosed as possibly boron deficient. I would like to add some. I assume I'd use either Borax (do they still make that?) or boric acid. But I have no idea about the amounts. Anything I find is discussed in terms of acres and hectares, etc., etc., and I can't face that much math. I wouldn't trust myself. Any advice?
