So, already, to grow good potatoes and hope for an abundant harvest, favor a rich, supple and well-drained soil. If you have a soil well supplied with clay, prepare it in advance with loose and refined soil (easy to work), to be applied deeply to allow the tubers to grow in good conditions. Make sure the soil is neither too alkaline nor too acidic. The ideal pH should be between 5.1 to 6.0. Ideally, you should dig slits 15 cm deep to install the tubers, before covering them with soil, but without compressing it. Also remember to leave space between the potato plants. Around each, on absolutely all sides, keep a distance of 12 centimeters, so that they grow healthy.

But beware, any good gardener must respect this golden rule: never plant potatoes in the area where the tomatoes or eggplants were grown the previous year. Otherwise, they may attract a lot of parasites and other similar problems. The problem is that many people completely neglect this detail and mix their plantations without having precise knowledge on the subject. As they say, towels and tea towels don’t mix! Keep in mind that some vegetables may affect potato production if grown nearby. Which ? We are talking in particular regarding beans, broccoli, cabbage, corn, eggplant, garlic, onions, peas or even radishes. Not only will your potatoes not grow properly, but above all these inappropriate mixtures risk attracting an invasion of insect pests such as beetles. Likewise, potatoes also do not enjoy the company of cucumbers, melons, squash, tomatoes or sunflowers.

What plants can be associated with potatoes without risk?

So you wonder what would be the ideal companions for your potatoes this year? You can gladly cultivate them alongside certain aromatic herbs which will be very useful in the kitchen to concoct tasty dishes. Here are two to plant without hesitation!

What might be more delicious than a roast flavored with thyme and accompanied by sautéed potatoes? This very popular herb is known to have properties that improve the flavor of potatoes. As a bonus, thanks to the thymol, contained in the essential oil of thyme, you can be sure that harmful parasites will not disturb the plantation. As soon as the grass blooms,
thyme attracts hoverflies (midges) which control sap-sucking insects. And that’s not all: the more the thyme spreads, the more beneficial the ground cover is for driving out weeds, conserving humidity and maintaining a more stable temperature.

Another protective herb: oregano, both spicy and fragrant, remains the perfect plant to ward off pests that try to ravage your potatoes. As a bonus, it is deer resistant and makes an excellent ground cover. Not to mention that oregano flowers are an important source of nectar for some beneficial predators like lacewings. Finally, thanks to its antiseptic and antifungal properties, oregano is perfectly suited for the intercropping of nightshade plants, such as potatoes or brassicas (cabbage, turnips, broccoli, rapeseed, etc.).

What other vegetables should not be planted together?

Of course, to make your job easier, it would be very practical to mix cultures. But, as you have just seen, certain combinations may slow down the harvest. And, of course, that’s not your goal! So, to avoid problems, it is better to refrain from it. Are you worried regarding making an unintentional mistake? Do not worry, to ensure a robust harvest, we will guide you and reveal the alliances to avoid.

A priori, in a plate, the association is not ugly. But, in the vegetable garden, the two do not make a pair! Planted nearby, onions clearly retard the growth of beans, but also peas. On the other hand, for a happy neighborhood, peppers, lettuce and carrots go well with onions. As for beans, because they fix nitrogen well in the soil, vigorous growers like corn and potatoes love to grow alongside them.

Cabbage (and other brassica vegetables, such as broccoli and kohlrabi) inhibits the growth of nightshade family vegetables, such as peppers. So, no question of bringing them together. That said, peppers will grow abundantly near onions, tomatoes, and eggplants. And cabbage will find its happiness alongside mint, cucumber or lettuce.

Ouch! Don’t even consider intercropping sage with cucumber plants, it will noticeably stunt their growth and attract all sorts of pests. Your pretty cucumbers will grow peacefully near dill, peas and radishes. As for sage, its best location is near rosemary, cabbage, and even carrots. Enough to dissuade insects from destroying its culture.

  • Potatoes and courgettes

Going back to the potato, even if you love to eat them together, it is better to avoid growing them near zucchini. For what ? Although both of these vegetables grow quickly, potatoes are known to be voracious. They tend to deplete available nutrients in the soil, leaving zucchini struggling to survive. So it’s not the best choice. To promote a good harvest, the latter will be more serene alongside corn, melons and beans. Best to keep your potatoes in the area where you grow horseradish or herbs like basil and thyme.
