Grow Lush, Thriving Plants for Less: DIY Liquid Fertiliser from Everyday Scraps.

Grow Lush, Thriving Plants for Less: DIY Liquid Fertiliser from Everyday Scraps.

Brewing liquid fertiliser from everyday scraps is a budget-friendly and eco-conscious way to nourish your plants. Let's explore how to create nutrient-rich concoctions from common household and garden materials:


Ingredient Powerhouse:

  • Kitchen Castoffs:

    • Fruit and Veggie Peels: Banana, potato, citrus, and more!
    • Coffee Grounds: Packed with nitrogen.
    • Eggshells: A calcium champion.
  • Yard and Garden Riches:

    • Grass Clippings: Another nitrogen source.
    • Weeds (pre-seed): Avoid spreading unwanted guests.
    • Plant Trimmings: Leaves, stems, and prunings.
  • Extra Boosters:

    • Manure: Aged or composted to prevent scorching.
    • Seaweed: Full of trace minerals.
    • Fish Scraps (heads, bones, guts) for a potent fish emulsion.



Brewing Methods:

  1. Compost Tea:

    • Ingredients: Compost or compostable materials (kitchen scraps, garden waste).
    • Recipe: Steep materials in a water-filled container for days or weeks, stirring occasionally.  Strain solids and dilute the mix before feeding your plants.
  2. Manure Tea:

    • Ingredients: Aged or composted manure (cow, horse, chicken).
    • Recipe: Submerge a burlap sack or pillowcase filled with manure in a bucket of water. Steep for days or weeks, stirring occasionally. Dilute before use to avoid harming plants.
  3. Weed Tea:

    • Ingredients: Weeds (pre-seed).
    • Recipe: Steep weeds in a water-filled container for several weeks. Strain solids and use the diluted liquid as fertiliser.
  4. Seaweed Elixir:

    • Ingredients: Fresh or dried seaweed (rinsed to remove excess salt).
    • Recipe: Steep well-rinsed and chopped seaweed in water for days or weeks. Strain solids and dilute them before using them as fertiliser.
  5. Fish Emulsion Power Food:

    • Ingredients: Fish scraps (heads, bones, guts).
    • Recipe: Fill a bucket with fish scraps and water, letting it ferment for weeks with occasional stirs. Strain solids and dilute them before using them as liquid fertiliser.


Fertiliser Wisdom:

  • Dilution is Key:

    Always dilute liquid fertilisers to prevent burning plants (typically 10 parts of water to 1 part fertiliser).
  • Application Options:

    Use liquid fertiliser as a soil drench or foliar spray.  Targeting the base of plants or leaves directly.
  • Feeding Frequency:

    Apply every 2-4 weeks during the growing season, adjusting based on plant needs and nutrient deficiencies.
  • Storage Secrets:

    Keep liquid fertilisers in sealed containers in a cool, dark place, using them within a few weeks for the best results.



By creating your liquid fertiliser from household scraps and garden waste, you're reducing waste, boosting soil health, and promoting vibrant plant growth – all without relying on synthetic chemicals.

It's a win-win for your garden and the environment!
