Orange peels are more than kitchen waste—they are rich in nutrients that support plant growth. By using orange peel as fertilizer, gardeners can naturally improve soil health, increase plant resistance, and reduce waste. Whether composted, dried, or turned into liquid fertilizer, orange peels offer numerous benefits.

1. How to Make Orange Peel Liquid Fertilizer

To make orange peel liquid fertilizer, chop orange peels and soak them in water for 5–7 days. Use a 1:3 ratio (one part peels, three parts water). Stir daily. After steeping, strain the liquid and use it to water plants directly.

2. Orange Peel Fertilizer Benefits

• Rich in potassium, calcium, and magnesium
• Helps ward off pests naturally due to citrus oils
• Improves soil acidity balance
• Enhances microbial activity in the soil

3. Orange Peel Liquid Fertilizer for Plants

Orange peel liquid fertilizer is suitable for houseplants, flowering plants, and even leafy greens. It offers slow-release nutrition and promotes healthy foliage. Avoid overuse, and always dilute if the scent is too strong.

4. Orange Peels in Potted Plants

Small chopped pieces of orange peel can be added to potted plants’ topsoil. Cover them with a layer of mulch or soil to avoid attracting pests. Alternatively, add the peels to potting mix as compost.

5. Orange Peel Fertilizer NPK

Orange peels contain key macronutrients:

• N (Nitrogen): Moderate
• P (Phosphorus): Low
• K (Potassium): High

This makes orange peel fertilizer especially useful during the fruiting and flowering stages of plant growth.

6. How to Use Orange Peels for Plants

– Compost them with other kitchen waste
– Dry and crush into powder and mix with soil
– Make citrus peel tea (liquid fertilizer)
– Use directly in potted plants (in small amounts)

7. Orange Peel Fertilizer for Tomatoes

Tomatoes thrive on potassium-rich soil. Crushed or composted orange peels provide the potassium needed for strong stems, flowering, and fruit production. Use composted peels at the base of tomato plants or add peel tea weekly.

8. Banana and Orange Peel Fertilizer

Combining banana and orange peels creates a balanced organic fertilizer. Bananas provide phosphorus and potassium, while oranges offer calcium and pest control. Blend both into compost, or make a peel tea to apply as a foliar spray or soil drench.

Conclusion

Orange peels are an underrated yet powerful tool for natural gardening. From composting and potting mix to liquid fertilizers, they can help reduce waste while enhancing plant vitality. Try using them alone or paired with banana peels for a nutrient-rich blend.
