The Benefits of Companion Planting Potatoes and Onions

Growing vegetables together is becoming an increasingly popular way of gardening. Companion planting involves the process of growing different crops together in a way that benefits both plants. When it comes to potatoes and onions, these two plants can be considered as the perfect companions. Companion planting potatoes and onions have several benefits:

Pest Control

Potatoes are known for attracting Colorado potato beetles, while onions repel them. When planted together, the scent of onions repels the beetles and keeps them away from the potatoes. Furthermore, the strong scent of onions also helps to repel other pests such as carrot flies and aphids.

Soil Health

Planting potatoes and onions together can help improve soil health. Potatoes need a lot of nutrients, while onions do not require as many. By planting them together, the onions will help to absorb some of the excess nutrients, preventing the soil from becoming too rich. Additionally, onions can help to suppress weeds by releasing sulfur compounds into the soil, which inhibits weed growth.

Maximizing Space

Companion planting potatoes and onions is a great way to maximize space in your garden. By planting them together, you can save space and grow more crops in the same area. This is especially beneficial for those with small gardens or limited space.

How to Companion Plant Potatoes and Onions

Now that we know the benefits of companion planting potatoes and onions, let's take a look at how to plant them together. Here are some steps to follow:

Choose the Right Varieties

When it comes to companion planting, it is important to choose the right varieties of potatoes and onions. For example, early varieties of potatoes such as 'Red Norland' or 'Yukon Gold' are best planted with early-maturing onions like 'Walla Walla' or 'Red Baron.' This will ensure that both plants mature at around the same time.

Prepare the Soil

Before planting, it is important to prepare the soil properly. Potatoes prefer loose, well-draining soil, while onions prefer slightly acidic soil. To create the ideal environment for both plants, mix in some compost and peat moss to improve soil drainage and add sulfur to increase acidity.

Plant the Potatoes and Onions

To plant the potatoes and onions, dig a trench about 4-6 inches deep. Place the potato seedlings in the trench, leaving about 12 inches between each plant. Cover the potatoes with soil, leaving a small mound on top. Next, plant the onion sets about 4-6 inches away from the potatoes. Cover the onions with soil and water thoroughly.

Maintain the Plants

Once the potatoes and onions are planted, it is important to maintain them properly. Water the plants regularly, especially during dry spells. Mulch around the plants to help retain moisture and suppress weed growth. Additionally, keep an eye out for pests and diseases and take action immediately if you notice any issues.

Rotate Crops

To prevent soil-borne diseases and pests from building up in the soil, it is important to rotate your crops each year. This means planting potatoes and onions in a different location every year.
