The tomatoes on my plants started to ripen with a bad case end blossom rot last month because there wasn't enough calcium in the soil to allow the tomato plant to grow well (this was news to me.)
I gave my tomatoes a good dose of this exact organic tomato fertilizer to get the calcium party started. I also started watering my tomato plants with a few teaspoons of powdered milk dissolved into my watering can. (Disclosure: I am including affiliate links in this post for your convenience.)
The only reason I used powdered not fat milk instead of watering down regular milk is I bought the no fat milk by mistake and didn't realize it until I used to make a batch of failed yogurt. Turns out my yogurt's loss is my tomato's gain.
After a week of having more little fails than successes laying bathroom
tile and sourcing material for a new costume commission, I finally have
a big, fat, huge win! My tomatoes are ripening and there isn't any black rot eating away at the end of the tomato!
My tomatoes are on the small side for Roma tomatoes but that probably has to do to the lack of calcium in the soil from the time I planted them. At least I know what not to do next year!
