Keeping your garden lush and thriving doesn’t have to mean spending big on store-bought fertilizers. In fact, some of the best plant food can be made right in your kitchen or backyard using natural ingredients you probably already have. These DIY organic fertilizers are simple, effective, and eco-friendly — helping your plants grow strong without harsh chemicals.

1. Compost Tea: The Garden Superfood

Compost tea is packed with nutrients and beneficial microbes that promote healthy soil and strong roots.

How to Make It:

1. Fill a 5-gallon bucket one-third full with mature compost.
2. Add water until full and let it steep for 24–48 hours, stirring occasionally.
3. Strain out the solids and use the liquid to water your plants or spray directly onto leaves.

Pro Tip: Use compost tea within a few days for maximum potency.

2. Banana Peel Fertilizer for Potassium Boost

Banana peels are rich in potassium, magnesium, and calcium — nutrients essential for flowering and fruiting plants like tomatoes and roses.

How to Use:

• Soil Boost: Chop banana peels into small pieces and bury them near plant roots.
• Liquid Version: Soak peels in water for 2–3 days, then use the infused water to nourish your plants.

4. Coffee Grounds for Acid-Loving Plants

Used coffee grounds add nitrogen and organic matter to the soil, perfect for blueberries, azaleas, and hydrangeas.

How to Use:

• Mix grounds directly into the top layer of soil.
• Or, compost them first to balance acidity before spreading.

5. Epsom Salt Solution for Magnesium and Sulfur

Epsom salt supports chlorophyll production and improves nutrient absorption.

Recipe:

Use as a foliar spray or soil drench once a month for leafy greens and peppers.

Dissolve 1 tablespoon of Epsom salt per gallon of water.

6. Seaweed or Kelp Fertilizer for Trace Minerals

If you live near the coast, seaweed is a goldmine of trace nutrients.

How to Make:

1. Rinse fresh seaweed to remove salt.
2. Soak in a bucket of water for a few weeks.
3. Strain and dilute 1 part seaweed water to 2 parts fresh water before applying.
