Can You Compost Potatoes

Yes, Potatoes are compostable material, however, it is a difficult process because it demands extra care and more advanced composting techniques. You can successfully compost potatoes, but after chopping them because if left intact, they can grow new ones or attract pests.

However, potato peelings and skins can rot down quickly, so you can easily compost them without worry. This comprehensive guide explores the detailed process of composting potatoes, including preparation practices and considerations. So, read until the end and be an informed gardener!

Can You Compost Potatoes

Yes, Potatoes are compostable material and a good addition to your compost pile. Potatoes belong to the finicky crop, they grow best, store well, and are prolific. However, they are prone to some potential diseases e.g. potato blight which is a fungal disease that destroys the stems and roots of plants. This disease also significantly affects tomatoes, potatoes, and peppers.

Potatoes are the favorite of this disease, so you will mostly find potato blight in potato plants. If there is a blight-diseased potato in the compost, it will be easier to recognize, so if you notice a diseased potato, then throw it away.

Do not add those potatoes to the compost if they have a disease or are infected. However, you can use potato peels off the infected or diseased potatoes to compost instead of using whole potatoes. Overall Potato scraps and peels are valuable additions to your compost bin. Their decomposition time is relatively quick and provides nutrients like potassium and phosphorus to your compost pile. 

Can Cooked Potatoes Be Composted

The composting of potatoes is not only limited to the raw ones instead, you can also compost cooked potatoes. Indeed, cooked potato compost works significantly in compost piles because cooked potatoes can break down quicker than raw potatoes. Just like humans can digest cooked potatoes quickly, compost gets all the nutrients from cooked potatoes quicker than uncooked potatoes.

Cooked potatoes break down quickly, so tiny micro-organisms absorb into the compost to digest quicker. Some people hate the decaying smell of cooked potatoes, so they hesitate to use them in compost. Do not add cooked potatoes to soil or compost if you think that way. But remember that it will take many years to break down and mix into the soil.

Adding cooked potatoes will give you the benefit that they will break down within a few months, and your garden plants will start growing faster and healthier before that time. So, if you are hesitant to add cooked potatoes to the compost, don’t worry, they will not harm your compost or plants. Just bear the decaying smell for a few days, you get used to it after a few days.

Cooked potatoes can quickly make your compost healthier and more nutritious than raw potatoes, so adding them will not be lost. Hence, addition of the cooked potatoes to your compost is highly beneficial. After composting them, you will notice that your plants or gardens regain their natural green colors within a few months. 

How Long Does it Take for Potatoes to Compose

Potatoe peels in a well-managed compost pile take about three to six months to decompose properly. Whereas, the whole potatoes and their pieces take time depending on the specific conditions like heat, moisture, and aeration. However, the time limit to decompose is between 3 months to a year. The addition of cooked and chopped potatoes in the compost pile will help them decompose more quickly.

How to Compost Potatoes

One of the easiest ways to reduce waste and improve your compost pile by adding essential nutrients is to compost potatoes. Here are tips on how to go about it:

1. Preparation

Separate the Potato pieces, including peels, and skins, and ditch the spoiled ones or other remnants. To speed up their decomposition, slice big pieces into smaller portions.

2. Balancing Ingredients

Due to their high nitrogen content, potatoes are one of the “green” materials used in composting. Mix two potato scraps with one part of brown materials such as dried leaves, straw, or shredded paper by volume to achieve this balance. This creates an environment that is perfect for decomposition.

3. Layering

Place potato scraps with other compost materials in layers, alternating between green and brown layers. This will ensure enough air movement in the pile and keep it from packing too tight.

4. Moisture

Water the compost pile regularly so that it remains moist but not saturated. Although these crops possess water, they can also take water from the pile. It is vital to monitor the moisture present and add more when necessary to keep the heap damp without getting soaked.

5. Turning

Turn in the compost pile regularly to aerate it and promote decomposition. This ensures a good distribution of heat and oxygen throughout the heap, which causes organic substances, including potatoes, to break down faster.

6. Cover

A tarp or lid on your compost bin helps retain moisture, effectively covering piles of waste material for decomposition. This keeps the smell within, while pests can also be locked out.

7. Patience

It usually takes weeks or months for potatoes to decay during composting, depending on various factors like temperature, moisture content, and the size of the potato pieces. Therefore, keep going until all the tubers are gone.

8. Harvest Compost

Once potatoes and other compost materials have fully decomposed, compost is ready for use, forming a dark, crumbly matter resembling soil. To feed the plants and enhance the fertility of your garden’s soil, you should harvest finished compost and mix it with the garden soil.

If you follow these steps, you can effectively turn potato peels into nutrient-rich compost for your garden. Keep an eye on the pile to ensure conditions are ideal for decomposition.

Best Potato Planting Practices

Whether you add potatoes in the garden, containers, or compost, a few potato composting practices will help you do the process successfully. These practices help you prevent blighted and diseased potatoes from composting and give your garden a chance to grow healthy. 

1. Buy Certified Seed Potatoes

Try to buy certified seed potatoes so that you have to face no blight potatoes. Spores can survive in dormant spuds, so choosing fresh and seed potatoes will prevent blight-infected potatoes. The store-bought potato seeds are good enough, however, they have a higher risk of blight in them. Hence, using them is not recommended.

When you are choosing potato seeds, always look for clear and diseased-free seeds. Almost all potato seeds are less or highly resistant to blight, so you must select the highly resistant seeds to ensure the best composting. Before introducing any potato variety to your garden, it will be better to research the potatoes and their seeds to check which ones are the best and which composting will suit your garden. 

2. Chit Seed Potato

Chit Seeds potatoes are best if you want healthy, blight-free potatoes for your compost. Chitting is when potatoes are sprouted before adding them into the compost. In this process, you have to check the planting calendar for the perfect time to compost potatoes into the soil.

For this purpose, you need a container with enough space to place potatoes upright and have proper air circulation space. Egg cartons are perfect for the process; you can set each potato with the eye upright. Next place this container at about 50–70 degrees Fahrenheit for a duration of four to six weeks.

In this time, sprouting shoots of potatoes became visible and you cut them into smaller pieces a few days before planting. Each piece of the potato must have three shoots; if there is a smaller seed potato, plant it whole. Ensure to grow the potatoes without breaking or harming them. The chitting process will prevent potatoes from being infected or blighted. 

3. Plan Your Vegetable Garden

Efficiently plan your vegetable garden as to prevent diseases or blights. Try to alternate the rows of potatoes with other varieties to prevent the chances of diseases or blights. In addition, plant the potatoes in a different space far from the peppers and tomatoes to prevent them. Try to find blight-resistant varieties. 

That will help you plant healthy potatoes when they grow blight-free, you can use them to add to the compost. Buying potato seeds from the store is inappropriate because they can be blighted. So make sure to grow blight-free potato seeds to ensure healthy compost later. 

Considerations for Composting Potatoes

While composting potatoes, there are a few things that you must consider. The amount you will use to add to the soil makes a difference. Any nitrogen-heavy waste should not overpower the compost. Make sure not to add too much waste into the soil, that waste in a compost pile should be made up of a nitrogen-rich source, such as fresh plant cuttings or grass clippings. 

Half of the waste you will add to the compost must have carbon-rich materials, like paper, brown garden waste, and cardboard because these waste materials help the compost grow healthy. If there is too much nitrogen or carbon, the decaying process of the materials will slow down. When you notice the balance of nitrogen and carbon is delicate, be cautious with smaller compost bins. 

It is better to watch for moisture and mix to ensure the compost potatoes decay smoothly. Make sure to keep your compost as wet as a kitchen sponge. To introduce fresh oxygen to the compost, mix the compost with a garden rake or similar tool for a week. This will keep your compost healthy and moist. Moist and airy compost is best for letting the materials break down quickly. 

Can Potatoes Affect the  Composting Process

There are a few problems created by potatoes that can potentially affect the composting process. The details of such factors are mentioned below: 

Microbial Activity

Microorganisms require aerobic conditions, with proper aeration to promote efficient decomposition. Excess of oxygen and moisture due to the over quantity of potato scraps led to anaerobic decomposition and often resulted in bad odor.

Moisture and Temperature

Potatoes in compost pile demand regular heat and turning resulting in increased nitrogen content in the compost pile. Thus, maintain the proper regulation, and ensure the aeration, dampness, and integration of carbon materials to balance the brown and green.
