10 Clever Ways to Reuse Food Scraps in Your Garden

Reusing food scraps in your garden is a simple and effective way to reduce waste while improving your soil and plant health.

Instead of throwing scraps in the trash, you can turn them into valuable resources for your garden.

Below are 10 clever ways to make the most of food leftovers, all while keeping your gardening efforts eco-friendly and sustainable.

1. Compost Your Food Scraps

Composting is the most popular way to reuse kitchen scraps. Turn vegetable peels, fruit cores, eggshells, and coffee grounds into nutrient-rich compost for your garden.

The compost improves soil quality, providing plants with essential nutrients. Start with a simple compost bin and avoid adding dairy, meat, or oily foods.

How to Start Composting

• Collect scraps in a small kitchen bin.
• Layer them with browns (like dry leaves) and greens (scraps).
• Keep the compost slightly moist and turn it regularly to speed decomposition.

2. Use Coffee Grounds as Fertilizer

Coffee grounds are an excellent nitrogen-rich addition to your garden. They help improve soil structure and provide nutrients for plants like roses, azaleas, and tomatoes, which thrive in slightly acidic soil.

Tip for Using Coffee Grounds

Sprinkle coffee grounds around the base of plants or mix them into the soil to enhance its quality. Avoid using too much as it can compact the soil.

3. Turn Eggshells into Plant Boosters

Eggshells are packed with calcium, an essential nutrient for plants like tomatoes and peppers to prevent blossom-end rot.

How to Use Eggshells

• Crush the eggshells into small pieces and scatter them around your plants.
• Add crushed shells to compost for an extra nutrient boost.
• Use them as biodegradable seed starters by filling halves with soil and seeds.

4. Make Banana Peel Fertilizer

Banana peels are rich in potassium and phosphorus, which help plants grow stronger and healthier.

Banana Peel Tea

Soak banana peels in water for 24-48 hours to create a natural liquid fertilizer. Pour this nutrient-packed water onto your plants for an easy growth boost.

5. Regrow Vegetables from Scraps

Did you know you can regrow vegetables like lettuce, celery, and green onions from their scraps? It’s a fun, sustainable way to reuse food leftovers.

Steps to Regrow Veggies

• Place the root ends of vegetables in a small container of water.
• Set it in a sunny spot and watch as new growth appears.
• Transfer the regrown veggie into soil for continued growth.

6. Use Citrus Peels to Repel Pests

Citrus peels, like those from oranges and lemons, are natural pest repellents. The scent keeps ants, mosquitoes, and cats away from your garden.

How to Apply Citrus Peels

Place citrus peels around plants or near garden entry points to deter pests. You can also create a spray by soaking peels in water overnight.

7. Feed Plants with Vegetable Cooking Water

Save the water used to boil vegetables—this nutrient-filled liquid makes a natural fertilizer for plants. It contains vitamins and minerals that leach from the vegetables during cooking.

How to Use Cooking Water

Let the water cool completely, then pour it around your plants. Avoid using salted water as it can harm plants.

8. Use Onion and Garlic Peels as Natural Mulch

Onion and garlic peels can act as a natural mulch, helping suppress weeds and retain moisture in the soil. They also contain sulfur compounds that deter pests.

How to Use Peels as Mulch

Scatter the peels around your plants or mix them into your compost pile to break down naturally.

9. Add Potato Peels to Compost

Potato peels are full of starch and minerals that help enrich your compost. However, make sure the scraps are free of mold or sprouting to prevent unwanted plants from growing.

Quick Tip

Mix potato peels well into your compost to ensure they break down evenly without attracting pests.

10. Use Nut Shells for Soil Aeration

Nut shells, like those from peanuts and pistachios, are perfect for improving soil drainage and aeration. They break down slowly, making them a long-term solution.

How to Use Nut Shells

Crush the shells into smaller pieces and mix them into your garden soil to keep it light and well-aerated.
