Ingredients

  • 1 gallon rainwater
  • 1 tablespoon ammonia
  • 1 tablespoon baking powder
  • 1 tablespoon salt
  • 1 tablespoon pepper
  • 1 rusty nail
  • 1 tablespoon Epsom salt

Instructions

  1. Combine 1 gallon of rainwater with 1 tablespoon of ammonia.
  2. Add 1 tablespoon of baking powder to the mixture.

  4. Drop in 1 rusty nail for added minerals.
  5. Stir in 1 tablespoon of Epsom salt.

Tips & Substitutions

For best results, use distilled ammonia to avoid impurities that may harm plants. If you don't have Epsom salt, magnesium sulfate can be a good substitute. Ensure your rainwater is collected properly to prevent contamination. Be cautious with the rusty nail; while it adds minerals, too much iron can harm sensitive plants. This mixture can be used as a base for homemade vegan recipes.

This homemade mixture pairs beautifully with other natural gardening methods, enhancing the overall health of your plants.

Storage & Reheating

Frequently Asked Questions

Can I use tap water instead of rainwater for this recipe?

While tap water can be used, it is often treated with chemicals that may harm beneficial microbes. Rainwater is preferred because it is chemical-free and provides a more natural nutrient source for your plants. If using tap water, let it sit out for 24 hours to allow chlorine to dissipate.

How often should I apply this plant food?

It's recommended to apply this mixture every 4-6 weeks during the growing season. Monitor your plants' health and adjust the frequency based on their needs. Over-fertilizing can lead to nutrient burn, so always ensure the soil is adequately moist before application.

Is this plant food safe for all types of plants?

Most plants will benefit from this homemade plant food, but sensitive plants may react negatively to the salts and minerals. Always do a patch test with a small amount on a single plant before widespread application. If in doubt, research specific needs for your plant types.
