  • Add compost in a porous bag or directly into the water.
  • Aerate the mix with a pump or stir every day.
  • Brew for 24–48 hours until it is earthy scented.
  • Strain and use on soil or as a foliar spray.

Benefits of Compost Tea:

  • Makes plants more resistant to pests and diseases.
  • Increases soil microbial diversity.
  • Increases nutrient availability for plants.

Gardeners everywhere regard compost tea as one of the finest natural fertilizers to use to promote healthy growth without deleterious side effects.

Best Natural Fertilizers for Your Garden

In selecting the best natural fertilizers, look at what your soil requires most. Some of the best ones are:

  • Compost – Balanced, nutrient-dense soil conditioner.
  • Manure – Provides nitrogen, phosphorus, and potassium, particularly when well-rotted.
  • Bone Meal – A phosphorus-containing amendment for root growth.
  • Seaweed Extract – Supports plant resilience and growth.
  • Green Manure (Cover Crops) – Naturally enriches the soil by fixing nitrogen.

Each of these fertilizers functions in a different manner, so strategically using them together provides balanced nutrition. For instance, compost enhances soil health, whereas bone meal targets root establishment.

Vinegar spray

Diluted vinegar in water will benefit any plants that like acidic soil (e.g., blueberries and azaleas), by lowering the pH of the soil.

Wood ash

Wood ash can be spread, as it is a natural source of potassium and calcium.

Aloe vera gel

Aloe vera contains enzymes and growth hormones that help with seed germination and root development.

These enhancers are inexpensive ways to provide plants with a continuous source of nutrients and improve the harmony in the soil.
