If you’ve been throwing away kitchen scraps, you’ve also been throwing away free fertilizer. At Vegglo, we show you how to convert your organic waste into a powerful liquid feed—compost tea. It’s rich in nutrients, easy to make, and perfect for small urban gardens, balconies, and sack farms.

🍌 What Is Compost Tea?

Compost tea is a liquid fertilizer made by soaking decomposed organic matter or food waste in water. It acts like a natural tonic, delivering nutrients directly to your plants’ roots and leaves—without any synthetic chemicals.

Benefits of Compost Tea:

  • Boosts plant growth and leaf color
  • Improves soil health and microbial activity
  • Fights off diseases naturally
  • Reduces waste and saves money

🧃 How to Make Compost Tea from Kitchen Waste

You Will Need:

  • 1 bucket (10–20L)
  • Vegetable scraps, fruit peels, eggshells, tea leaves, crushed charcoal
  • Water (preferably rainwater or dechlorinated tap water)
  • Old sock or porous cloth (optional, for straining)
  • A stirring stick

Instructions:

  1. Add chopped scraps to half-fill your bucket
  2. Fill with water until 2–3 inches from the top
  3. Cover loosely (allow air in but keep flies out)
  4. Stir once daily for 7–10 days
  5. Strain the liquid and dilute it: 1 part compost tea to 3 parts water

Use the remaining solids in your sack garden or compost pile.

✅ What You Can Use:

  • Banana peels – potassium boost
  • Eggshells – calcium for strong cell walls
  • Onion skins – antifungal properties
  • Vegetable peels – nitrogen and trace minerals

❌ What to Avoid:

  • Oily food or cooked leftovers
  • Meat, fish, or dairy (they attract pests and rot)
  • Chili or heavily spiced scraps
  • Citrus peels in large amounts (too acidic)

🌿 How to Apply Compost Tea

  • Pour at the base of plants every 7–10 days
  • Use a spray bottle for foliar feeding on spinach, sukuma, and herbs
  • Apply in the morning or evening (not under strong sun)
