Gallon of water, 1 chopped onion add to gal of water. let it sit under the sun for 3days and spray it over your veg plants, n flowers to keep bugs from eating the leaves.

Self made Miracle Grow. Put 1 Tbs. Epsom Salt, & 1 Tbs. Sugar into each hole with your plant. It makes them grow larger, leafier and greener. Or dissolve 1 Tbs. Epsom Salt into 1 Gallon of water and use it to water your plants, trees, fruit trees, roses, flowering plants, squash,and all other veggies. For plants you have planted in ground or pots sprinkle Epsom Salt on top of the dirt/potting soil and water well. See Link for other ideas.
