Step 1

Pick a big watermelon and eat the watermelon pulp, leaving only the watermelon skin

Step 2

Use a spoon to scrape off the red pulp in the watermelon skin, because the sugar content in the pulp is too high. Putting it together with the watermelon skin for composting is easy to attract small flying insects and ants

Step 3

Use the kitchen knife to cut the watermelon peel vertically into thin strips. When cutting, pay attention not to let the knife cut your hand

Step 4

Cut the watermelon skin horizontally with a kitchen knife and cut it into small dices one by one

Step 5

Put the watermelon peel into the plastic bottle, don't fill it too full, and leave space for one finger

Step 6

After the watermelon skin is packed, there is no need to add water to the plastic bottle, and then close the cover. The cover should not be too tight and leave some seams to avoid flatulence

Step 7

Put the plastic bottle containing watermelon peel on the sunny place on the balcony. The more the sun shines, the easier it is to rot and the faster it ripens

Step 8

Open the lid of the plastic bottle every day to breathe. Watermelon peel composting generally has no taste. If you are worried about taste, you can put in some orange peel

Step 9

In summer, water will come out after retting watermelon peel for 10 days and a half months. This water can be poured out and directly used to water and fertilize the flowers. The rest of the watermelon peel can be put in the bottle to continue drying until the watermelon peel no longer flows out. The remaining watermelon peel residue can be buried at the bottom of the pot as the base fertilizer for flowers

Step 10

If you are a novice and are worried that the retted watermelon peel water will burn the roots, you can dilute it according to the ratio of watermelon peel water: clear water = 1:10, and then water the flowers after dilution

Step 11

Fertilize the flowers with watermelon peel, the effect is very good! Azalea, jasmine, gardenia and Begonia are suitable for all kinds of flowers, and the fertilizer effect is mild without damaging the root
