Don’t throw away watermelon rinds, use them to make fertilizer, it’s useful and costs no money!

Step 1

Pick a large watermelon and eat all the flesh, leaving only the rind.

Step 2

Use a spoon to scrape out the red flesh in the watermelon rind. This is because the flesh has too high a sugar content and if it is fermented together with the rind, it will easily attract small flies and ants.

Step 3

Use a kitchen knife to cut the watermelon rind vertically into thin strips. Be careful not to cut your hands with the knife when cutting!

Step 4

Use a kitchen knife to cut the watermelon rind horizontally and cut it into small pieces.

Step 5

Put the diced watermelon rind into a plastic bottle. Don't fill it too full, leave about a finger's worth of space.

Step 6

After putting the watermelon rinds in the bottle, do not add water to the plastic bottle. Then put on the lid. Do not close the lid too tightly, leave a gap to avoid bloating.

Step 7

Place the plastic bottle containing watermelon rinds in a sunny place on the balcony. The more sunlight they get, the easier it is for them to rot and the faster they will mature.

Step 8

Open the lid of the plastic bottle every day to let it air out. Watermelon rind compost generally has no odor. If you are worried about the odor, you can put some orange peel in it.

Step 9

In summer, watermelon rind will produce water after fermenting for 10 days to half a month. This water can be poured out and used directly to water the flowers and provide fertilizer. The remaining watermelon rind can be placed in a bottle and continue to be dried in the sun until the rind no longer releases water. We can bury the remaining watermelon rind residue at the bottom of the pot as base fertilizer for the flowers.

Step 10

If you are a beginner and are worried that the fermented watermelon rind water will burn the roots, you can dilute it in the ratio of 1:10 and then water the flowers after dilution.

Step 11

Using watermelon rinds to fertilize flowers is amazing! It is suitable for all kinds of flowers such as azalea, jasmine, gardenia, and crabapple, and the fertilizer has a mild effect without damaging the roots.
