Can You Compost Watermelon Rind?

Watermelon rind consists of the tough outer skin and the crisp green flesh beyond the juicy red fruit. While it isn’t the tastiest part of the melon, the rind is packed with essential vitamins and minerals. When you add it to your compost, you introduce a component packed with nitrogen, potassium, zinc, magnesium, and other beneficial nutrients for your plants.

How to Add Watermelon Rind to Compost

A watermelon rind is part of the “green” material in compost, the nitrogen-rich component that helps feed nutrients to your plants. Along with watermelon rind, you can include food scraps, coffee grounds, and plant trimmings as green material.

Green material works alongside “brown” material to form a compost heap. Brown material consists of dry materials like newspapers, eggshells, twigs, dried leaves, and straw, providing carbon and appropriate airflow to maintain moisture levels. Keeping the compost from getting too soggy is crucial for proper decomposition and preventing stinky smells.

The ideal range for compost is 40%–60% moisture. When you squeeze a handful, it should feel like a damp sponge. Excessive moisture halts the flow of oxygen, which can kill off decomposing organisms. Compost also stores carbon dioxide and loses nutrients faster when it’s too wet.

Moisture is an essential consideration with watermelon rind because it introduces a lot to the heap. You’ll need to add plenty of brown material on top to absorb excess water. For most compost heaps, a 3:1 or 4:1 ratio of brown matter to green material will maintain the correct moisture and temperature levels.

You can help the organisms in your compost by cutting the watermelon rinds into chunks. Cut them into pieces less than 3 inches long to give them more edible surface area. Mix them with other green compost matter and layer on brown material to suck up excess moisture.
