Non-Fat Dry Milk/Calcium
Has anybody tried mixing non-fat dry milk into the soil around their tomato plants as an organic source for calcium? I think I read about this somewhere but not sure.
I actually think I tried this a couple of years ago and remember it preventing blossom-end rot, but drew ants.
What other calcium sources can I use instead of lime which neutalizes the soil too much? How about gypsom?
