7 Natural Homemade Fertilizers for Your Garden

7 Natural Homemade Fertilizers for Your Garden

Any gardener knows that fertilizers are important to maximize growth, but for those concerned about what’s in consumer fertilizers, there are numerous methods for creating your own fertilizer that will equal if not out perform products like Miracle Grow and other chemical laced products.

Natural liquid fertilizers are nutrient-rich solutions made from organic materials that can be easily absorbed by plants. These fertilizers often use common household and garden waste products, making them cost-effective and environmentally friendly alternatives to chemical fertilizers.

Why Make Your Own Natural Liquid Fertilizers

Sustainability: Natural liquid fertilizers are a cornerstone of sustainable gardening. By repurposing organic waste materials, such as kitchen scraps and garden clippings, these fertilizers minimize reliance on synthetic chemicals. This reduction in synthetic input decreases the carbon footprint of your garden and helps preserve natural ecosystems by reducing chemical runoff and soil degradation. Incorporating natural liquid fertilizers into your gardening routine supports a closed-loop system that benefits both your plants and the environment.

Nutrient-Rich: These fertilizers are packed with essential macronutrients and micronutrients. They provide nitrogen, phosphorus, and potassium in balanced proportions, ensuring comprehensive nutrition for your plants. Additionally, they supply trace elements like calcium, magnesium, and iron, which are important for various plant physiological functions. This rich nutrient profile promotes vigorous growth, enhances flowering and fruiting, and strengthens plants’ resistance to diseases and pests.

Easy Absorption: The liquid form of these fertilizers allows for rapid absorption and assimilation by plants. Unlike granular or solid fertilizers, which need to break down in the soil, liquid fertilizers deliver nutrients directly to the plant roots and foliage. This immediate availability accelerates nutrient uptake, leading to quicker visible results such as greener foliage, stronger stems, and more abundant blooms. This efficiency makes natural liquid fertilizers an excellent choice for both foliar feeding and soil drenching.

Soil Health: Beyond nourishing plants, natural liquid fertilizers improve soil health. They enhance soil structure by increasing its organic matter content, which improves aeration, water retention, and root penetration. Moreover, these fertilizers foster a healthy soil microbiome by providing food for beneficial microorganisms. These microbes, in turn, decompose organic matter, release nutrients, and form symbiotic relationships with plant roots. The result is a dynamic and fertile soil environment that supports long-term garden productivity and resilience.

Common Types of Natural Liquid Fertilizers

  1. Seaweed Fertilizer: Seaweed or kelp provides a broad spectrum of nutrients and growth hormones that enhance plant vigor and stress resistance. Seaweed fertilizer is especially beneficial during the early stages of plant growth and for helping plants recover from transplant shock​ (Misfit Gardening)​.
  2. Manure Tea: Aged manure from herbivores like cows, horses, and chickens steeped in water creates a nutrient-dense fertilizer high in nitrogen and other essential nutrients. Manure tea is excellent for heavy-feeding plants like corn and tomatoes during their vegetative growth stage​ (Epic Gardening)​.
  3. Banana Peel Fertilizer: Soaking banana peels in water releases potassium and other micronutrients beneficial for plant growth. This fertilizer is ideal during the flowering and fruiting stages of plants like tomatoes, peppers, and cucumbers​ (Misfit Gardening)​.
  4. Grass Clippings Tea: Fresh grass clippings are rich in nitrogen, making them perfect for leafy green vegetables. Steeping grass clippings in water creates a liquid fertilizer that boosts foliage growth early in the growing season​ (Misfit Gardening)​.
  5. Fish Emulsion: Made from fish waste, fish emulsion is high in nitrogen and other nutrients. It is excellent for all-purpose fertilizing and can be particularly beneficial for seedlings and young plants to support robust early growth​ (Epic Gardening)​.
  6. Coffee Ground Fertilizer:
    • Ingredients: Used coffee grounds, water.
    • Instructions: Mix used coffee grounds with water and let sit for a few days. Strain and use the liquid as a nitrogen-rich feed for acid-loving plants like blueberries and roses​ (Epic Gardening)​.
  7. Molasses Fertilizer:
    • Ingredients: Molasses, water.
    • Instructions: Dissolve 1-2 tablespoons of molasses in a gallon of water. Use this mixture to feed plants, providing them with a quick source of energy and boosting beneficial microbial activity in the soil​ (Epic Gardening)​.

DIY Methods for Making Natural Liquid Fertilizers

  1. Seaweed Fertilizer:
    • Ingredients: Fresh or dried seaweed, water.
    • Instructions: Rinse seaweed to remove salt, then soak in a bucket of water for 2-3 weeks. Strain and dilute 1 part seaweed solution to 5 parts water​ (Misfit Gardening)​.
  2. Manure Tea:
    • Ingredients: Aged manure, water, mesh bag.
    • Instructions: Place manure in a mesh bag and submerge in water for 4-8 weeks. Stir occasionally. Strain and dilute 1 part manure tea to 10 parts water before applying​ (Epic Gardening)​.
  3. Banana Peel Fertilizer:
    • Ingredients: Banana peels, water.
    • Instructions: Place chopped banana peels in a jar, fill with water, and let sit for 1-2 weeks. Use the liquid as a nutrient-rich feed diluted at a 1:5 ratio​ (Misfit Gardening)​.
  4. Grass Clippings Tea:
    • Ingredients: Fresh grass clippings, water.
    • Instructions: Fill a bucket with fresh grass clippings and cover with water. Let it steep for 1-2 weeks. Strain and dilute at a 1:10 ratio before use​ (Misfit Gardening)​.
  5. Fish Emulsion:
    • Ingredients: Fish scraps, water.
    • Instructions: Place fish scraps in a container, cover with water, and let sit for 2-3 weeks. Stir occasionally. Strain and dilute 1 part fish emulsion to 5 parts water​ (Epic Gardening)​.
  6. Coffee Ground Fertilizer:
    • Ingredients: Used coffee grounds, water.
    • Instructions: Mix used coffee grounds with water and let sit for a few days. Strain and use the liquid as a nitrogen-rich feed for acid-loving plants like blueberries and roses​ (Epic Gardening)​.
  7. Molasses Fertilizer:
    • Ingredients: Molasses, water.
    • Instructions: Dissolve 1-2 tablespoons of molasses in a gallon of water. Use this mixture to feed plants, providing them with a quick source of energy and boosting beneficial microbial activity in the soil​ (Epic Gardening)​.

Best Practices for Application

  1. Dilution: Always dilute concentrated fertilizers to prevent root burn and ensure even distribution. A common dilution ratio is 1 part fertilizer to 10-15 parts water.
  2. Timing: Apply liquid fertilizers during the early morning or late evening to reduce evaporation and maximize absorption.
  3. Frequency: Depending on the type and plant needs, apply natural liquid fertilizers every 1-2 weeks.
  4. Life Cycle Stage: Tailor the fertilizer to the plant’s growth stage. For example, use nitrogen-rich fertilizers like grass clippings tea during vegetative growth and potassium-rich fertilizers like banana peel fertilizer during flowering and fruiting stages.
  5. Storage: Store prepared liquid fertilizers in a cool, dark place. Use within a few weeks to prevent fermentation and loss of nutrient potency.
