Sprinkle Baking Soda on Cabbages (and other Brassicas) to Thwart Caterpillars If those small green cabbage worms have been making Swiss cheese of your cabbage, broccoli, and kale plants, try this trick: Make a 50/50 combination of flour and baking soda, and dust it all over whichever plants the cabbage worms are eating. They'll eat the combo while munching the leaves, and die within a day or so. Repeat as necessary.
Self made Miracle Grow. Put Epsom salts and sugar into each hole with your plant. It makes them grow larger, leafier and greener, use about 1 Tablespoon in a 1 to 1 ratio but I dont really measure it. You can also dissolve 1 Tablespoon into a gallon of water and use it to water your plants, trees, fruit trees, roses, flowering plants, squash,... all veggies. If you have already planted I would sprinkle around the plant and water it well
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!
Non toxic tomato worm control . I don't remember where I learned this, but I've been using this method for 30 yrs and it really works. Get yourself 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.
