Can You Compost Watermelon Rind?

Chopped watermelon

Watermelon is the fruit of the summer. We don't know about you, but the amount of watermelon we eat during the summer months is probably a little extreme. The pink flesh of a watermelon is tasty and perfectly refreshing on hot days. However, watermelon is such a healthy snack option we won't be complaining anytime soon.

This, unfortunately, results in a lot of rinds going to the bin. Since many of us rarely eat watermelon rind, it can seem like a frightening amount of waste.

So can you compost the rinds of your watermelons? Well, simply put, yes, you can 100% compost them. Not only will this reduce your household waste, but it can give you organic, nutrient-rich compost all the time. Especially if you use a countertop composter like Lomi, it will only take a couple of days to compost your food scraps fully.

It is best to chop up the watermelon rind into small pieces and compost it with other scraps. Put a thin layer of brown compost ingredients such as shredded newspaper, cardboard, or dry leaves on top of the mixture. This will help absorb excess moisture.


Can Watermelon Rind Be Composted?

Watermelon rind is an excellent source of nitrogen, nutrients, trace minerals, calcium, potassium, and moisture, which are all important for composting watermelon rinds. When popping them into your compost pile, it's best to chop them up into small chunks.

In addition to the melon rinds, you need to add browns. Composting with only food scraps can cause problems such as a lack of oxygen, and the moist environment can breed unhealthy bacteria and fungus.

Dry leaves, twigs, and shredded paper are fantastic examples of suitable brown waste.

Some birds will peck at the rinds to remove the last flesh, making it very difficult to compost watermelon flesh. For this reason, if you keep chickens or have regular visitors to your bird feeder, hang up the rind near their food for two days. This allows the rinds to be cleaned before composting.

An alternative to keeping a compost pile if you have limited space is to use an advanced, environmentally friendly system called Lomi. This system is small enough to go in your kitchen and breaks down food waste, organic waste, and Lomi Approved materials such as watermelon rinds. The result is nutrient-rich dirt that can be incorporated into your soil for a healthier garden.



Is Watermelon Rind Good For Compost?

Watermelon rind is a fantastic addition to a compost heap. In fact, composting is the most eco-friendly method for disposing of these leftover organic materials.

Most kitchen scraps, such as leftover vegetables and watermelon, are considered the green matter. As a result, compost piles become nitrogen-rich environments, facilitating the growth and multiplication of microorganisms.

To balance green compost materials, "brown" compost materials are required. Compost piles use carbon as a slow-release source of energy to maintain microorganisms. Newspaper, cardboard, dry leaves, and twigs comprise brown compost.

For a compost heap to be successful, it must be given a balanced diet of approximately half green and half brown elements as well as moisture and oxygen.


Why Should You Compost Watermelon Rind?

The U.S Environmental Protection Agency (EPA) estimates that almost 30% of every household's waste in America comprises a garden and food waste. This is a massive amount of waste that we need to reduce if we want to be kinder to our planet.

Although the skin of a watermelon is entirely edible, most people don't eat it. So you're only two options after that is to bin it and send it to landfill, or compost melons and their rinds in your compost pile.

Choosing to compost your watermelon rinds means you are reducing the impact on your environment by sending less of your waste to landfill and repurposing it into something incredibly useful - compost.

Composting at home can produce cleaner and more nutrient-dense compost than you can buy in the store. No matter the size of your garden or the plants you choose to grow, fresh compost will always give them a more varied and natural nutrient source.

What does this mean? Your plants will grow better and stronger. That's a win in our books.


 

 


Can You Compost Watermelon Seeds?

Just like how easy it is to compost melons, watermelon seeds can also be composted. However, there is a chance that the seeds could germinate before they have fully decomposed.

During the composting process, heat is produced, and although you would think that a lot of heat would kill off most seeds, the temperature in most backyard compost bins will not reach a point to kill seeds. Unless you have an incredibly hot compost pile, there is a risk that your watermelon seeds may germinate.

You can prevent your compost from being ruined by sprouted seeds. If the seeds are allowed to dry out before composting fully, there is less risk that they will germinate. By roasting them in an oven, you can speed the process along.

Hungry birds may also become very interested in a few loose watermelon seeds, much like any fresh watermelon flesh you may have left behind on the melon rinds that have ended up on your compost pile.

So, if you accidentally threw in a few watermelon seeds and you don't want any unexpected watermelon seedlings to take root, you could allow your compost to sit (and further decompose) for another few months.

As long as you are prepared for little seedlings or have pre-roasted the seeds, it's perfectly fine to compost melon seeds.


6 Ways To Use Watermelon Rind

Perhaps you have too much green waste in your compost pile. Here are some creative ideas for repurposing the whole melon rind - lots of the ideas also work really well for other types of melon rind.


Pickle It

It is best to make a watermelon pickle a few days before you want to use it, so the pickled watermelon rinds have time to develop their distinctive flavor.


Make Chutney

Chutneys can be made using the white rind, which has been removed from the outer green skin. It is a perfect accompaniment to a spicy curry, grilled chicken, or fish.


Use It In A Curry

Remove the outer green peel, and use the white rind to make a curry as you would a vegetable. This is a specialty dish in parts of India. Paired with spicy chiles and warm spices, watermelon rind provides a subtly sweet, cool complement paired with spicy chiles and warm spices. Even with a relatively quick cook time, the rind soaks up lots of flavors and softens without becoming mushy.


Prepare It As Gazpacho

Candy It

Many things can be candied, such as lemons, oranges, and grapefruit peels, so why not watermelon rind? Candied watermelon rind can be created from the leftovers of this summer fruit.


Add It To A Countertop Composter

Add it to your Lomi. Lomi lessens GHG omissions such as methane to break down approved organic compounds like your watermelon rinds. Once the process is complete, you're left with rich soil that can help your garden flourish when mixed with soil. 


What Is The Best Way To Add Watermelon Rinds To Compost?

There are two layers of green and brown materials in a basic compost bin or pile, along with a little water. Brown matter contains dead leaves, twigs, and cardboard and contributes carbon to the environment.

Vegetable scraps and other leftover foods make up green materials or matter, which is typically fresher than brown matter. As the two layers break down, compost will form. The surface area for microbes to break down watermelon rinds and banana peels increases when the materials are cut into smaller pieces.

If you compost melon rind without chopping them into smaller pieces, they will take a long time to break down because the rinds are often very large after you scoop out the tasty fruit.


Can You Put Watermelon Rinds Down A Garbage Disposal?

Vegetable and fruits waste

Watermelon rinds shouldn't be put down in the garbage disposal. It is best not to dispose of fibrous food items such as watermelon flesh and rinds, celery, banana peels, carrot scraps, and potato peels in your garbage disposal. They can cause damage to appliances by jamming blades with their strings and fibers.

Smaller skins may become wrapped around the blades of your disposal, causing your disposal to remain blocked for a long period of time. Melon parts that are large and hard may also take a long time to grind, especially if they have already caused damage to the machine.

Instead of throwing them down the garbage disposal, head over to the compost bin. Watermelon rind benefits are many, and even after you have finished eating the watermelon, the rind can be composted, providing additional nutrients, moisture, and nitrogen for your compost pile. They are contributing to the final compost and subsequently the garden and plants.

Watermelon rind is an excellent source of nutrients, calcium, potassium, moisture, and other trace minerals essential to composting. Composting watermelon rind is a perfect way to reuse this part of the fruit!
