Non toxic tomato worm control . Get an old jar & poke holes in the lid. Fill the jar with plain white flour and sprinkle it liberally over your tomatoes. I've never had an issue with horn worms or other pests with this. I also use it on cabbage & broccoli with good luck.
SECRET Fertilizer :) My 'fertilizing cocktail' consists of mixing 1/2 bottle of cheap beer, 1 tablespoon of Epson salts, and 2 tablespoons of fish emulsion in a watering can (1-2 gallons). I do this to ALL my vegetable, flowers, and indoor plants. You will definitely notice the difference in a few weeks! Don't waste too much money on the beer. Cheapest still works great -- plants aren't picky!
