After enjoying your oranges, set the peels aside instead of discarding them. Here’s how to dry them:
- Sun-drying: Lay the peels out on a tray in direct sunlight for 2–3 days, or until completely dry and crispy.
- Oven drying: Place them in a low-temperature oven (around 100°C or 210°F) for a few hours, checking regularly.
- Dehydrator or air drying: These methods also work, but may take longer. The key is to ensure no moisture remains.
The drier the peels, the easier they are to grind and the longer they’ll last in storage.
Step 2: Grind Into Powder
Once your peels are fully dry, break them into smaller pieces and place them in a blender, spice grinder, or food processor. Pulse until the peels become a fine or semi-coarse powder. A few small bits left behind won’t hurt, but the finer the powder, the easier it is to use.
Store the powder in a clean, airtight jar to keep it dry and ready for your next gardening session.
Two Powerful Ways to Use Orange Peel Powder in the Garden
1. Sprinkle It Directly Into the Soil
One of the simplest methods is to apply the powder around the base of your plants:
- Use 1–2 tablespoons per plant, depending on size.
- Gently work the powder into the top layer of soil using your fingers or a hand rake.
- Water the area lightly after applying.
This method gradually releases nutrients into the soil while also repelling soil-dwelling pests like ants and root-eating insects. It’s perfect for vegetable gardens, flower beds, fruit trees, or even potted plants.
2. Make a Natural Pest-Repelling Spray
To turn orange peel powder into a protective spray, follow this method:
Ingredients:
- 5 tablespoons of orange peel powder
- 2 liters of warm water
Instructions:
- Mix the powder with warm water in a large container or bowl.
- Let it sit for 30 to 60 minutes, allowing the beneficial compounds to infuse into the liquid.
- Strain the mixture through a fine cloth or sieve to remove any solid particles.
- Pour the liquid into a spray bottle.
How to use:
Spray the solution on your plant leaves — both top and underside — every few days or after rainfall. The citrus aroma acts as a natural repellent, keeping away aphids, ants, whiteflies, and other harmful insects.
You can use this spray on most plants, including edible crops, since it contains no chemicals or harmful additives.
