Is it Safe to Compost Potato Peels?

You might be wondering if composting potato peels is safe or not. It is absolutely safe to compost potato peels but only by employing proper methods and precautions. Anything that is biodegradable can be composted. So, potatoes with a huge inventory of minerals will obviously strengthen the soil and can help in plant growth if used as compost.

Just make sure that your compost does not grow potato blight (a fungal disease) while adding rotten potatoes in compost. Hence, instead of throwing potato peels, you can compost potato peels in your garden.

Potatoes contain minerals such as potassium, nitrogen, phosphorus, and magnesium, which help in the overall growth of the plant. Potato peels have been used as organic compost for decades as they tend to increase the fermentation process by creating a lot of heat.

Among the other common problems that can arise by adding potato peels to the compost pile, potato blight is the most fatal one. Potato blight is a fungal disease in potatoes which starts from the potato tubers resulting in rotting the whole potato sack.

Potato blight affects not only the potato but affects other crops as well. And adding potato peels with potato blight can rapidly increase the number of microorganisms that can negatively affect the plants. So, before adding potato peels to the compost pile, just make sure that there’s no possibility of potato blight.

Avoiding potatoes with blight in your compost is not that difficult, though. You can avoid adding store-bought and not-so-fresh potato peels into the compost pile.
