Upcycled Watermelon Rind for Plant Care: Turn Kitchen Scraps into Plant Gold

I love making the most of what I have. Whenever I see trends like the current watermelon craze, I think beyond just the food and into how it fits a mindful home lifestyle. And here’s something most people don’t realise: that pale green rind we usually throw away? It’s plant gold.

Upcycled Watermelon Rind for Plant Care: Turn Kitchen Scraps into Plant Gold

Instead of binning it, you can upcycle watermelon rinds into a natural, nutrient-rich boost for your indoor plants. It’s a brilliant way to cut waste, support your greenery, and stay aligned with the slow-living, Japandi-inspired approach many of us love.

Why Is Watermelon Rind Good for Plants?

Watermelon rind is an excellent option for plant care. Watermelon rind is packed with water, natural sugars, and trace nutrients like potassium and phosphorus—key for healthy plant growth. When composted or fermented, it becomes a gentle, organic fertiliser that feeds your plants and improves soil health.

How to Turn Watermelon Rind into Plant Feed

Option 1: Quick Chop & Compost

1. Cut the watermelon rind into small chunks.

2. Add to your compost bin or a countertop compost caddy.

3. Mix with browns, such as shredded paper or dry leaves, to balance moisture.

4. Once broken down, use the compost to enrich your houseplant soil.

Option 2: DIY Liquid Fertiliser (Fermented Rind Tea)

If you don’t have a compost bin, you can still give your plants a boost with rind tea:

1. Chop watermelon rind into pieces.

2. Place the item in a jar and cover it with water.

3. Let it sit for 3–5 days at room temperature (it will ferment slightly).

4. Strain and dilute the liquid (1 part rind tea to 10 parts water).

5. Water your plants with this gentle tonic for extra nutrients.

Option 3: Direct Soil Boost

If you’re potting a new plant, bury a few rind pieces at the bottom of the pot before adding soil. As they decompose, they’ll release nutrients slowly. Be mindful to cover them well so they don’t attract pests.

Why It Fits a Japandi Lifestyle

Japandi style is characterised by simplicity, harmony, and a respect for natural resources. By reusing what you have—in this case, watermelon rinds—you’re reducing waste and giving back to your home environment. Additionally, healthier plants create the serene, green interiors we all love.

Final Thought

The next time you’re blending up a trendy watermelon smoothie, don’t toss the rinds. With a little care, they can transform into a zero-waste plant booster that keeps your greenery happy and thriving. Small habits like this turn everyday moments into a sustainable living practice—and that’s something worth sharing.

FAQs: Using Watermelon Rind for Plant Care

1. Can I put watermelon rind directly into plant pots?

Yes, but it’s best to bury small pieces deep under the soil or at the bottom during repotting to avoid attracting pests. Over time, the rind will break down and release nutrients into the soil.

2. Does watermelon rind attract pests?

It can if left exposed. Always bury rind pieces well under the soil or compost them first. Alternatively, use a fermented liquid fertiliser made from rind to avoid this issue.

3. Can I freeze watermelon rinds for later use?

Absolutely. Chop the rinds into small pieces, store them in an airtight bag, and freeze. When you’re ready, defrost and use them for compost or to make fertiliser tea.

4. How often should I use watermelon rind fertiliser on my plants?

For liquid rind tea, a dosage of once every 2–3 weeks is sufficient. Overuse can lead to overly wet soil or attract mould, so moderation is key.

5. Is watermelon rind safe for all houseplants?

Yes, most houseplants benefit from the extra nutrients, but be cautious not to overfeed delicate plants or those prone to root rot. Always dilute liquid fertilisers and ensure good drainage.
