30 Potato Companion Plants And 8 Plants To Never Grow With

Earth up potatoes with high quality compost and mulch well with organic matter (such as seaweed, comfrey leaves etc..).Instead, choose companion plants for potatoes, to create polycultures or guilds around them to help them grow strong.In that article, you’ll find out more about how and why we use companion plants and create polycultures in an organic garden.While these claims have little scientific backing, there is a wealth of anecdotal evidence from gardeners and growers who swear to its efficacy.There is also some evidence to suggest that incorporating the organic material from horseradish plants into the soil around potatoes can, in certain circumstances, have pest controlling characteristics.It is the compound allyl isothiocyanate found in the plant which is said to have pest repelling properties.(Note, however, that horseradish is a member of the brassica plant family and can harbor common brassica pests, so should not be grown close to cabbages, kale, broccoli or other members of this plant family.).The pungent aroma of the garlic is said to repel certain species, and to confuse or distract others, making the primary plants in the bed more difficult for pests

growth of legumes such as peas and beans.Studies have suggested that yield on a certain area of land can be increased by intercropping of these two plants.In a warm climate, during hot summer weather, pea crops planted to provide shade to potatoes may also have a benefit, since the increased shade will reduce moisture loss from the soil and aid the potato crop, which requires relatively high levels of water.Studies into intercropping of beans and potatoes have shown that in certain circumstances, overall yield can be increased on a given area of land by planting the two together.Spinach is another example of a leafy green with shallow roots that can be sown around your potatoes early in the season.Sowing lettuce, spinach and other similar leafy greens will help you to make the most of the space you have available.Another benefit of sowing leafy greens like lettuce and spinach around young potato plants is that they can help to create good ground cover, which is another way to

they grow to fill the space and require the room and nutrients available.Radishes can also help the potatoes and the leafy greens planted alongside them by repelling flea beetles.Even better, harvest some thyme leaves ad sprinkle on your roast potatoes for a delicious flavor combo.Yarrow also attracts a range of beneficial insects, and its deep roots mean that it can be an effective dynamic accumulator.Yarrow grown as a companion alongside other aromatic herbs can also help increase their essential oil production, which can boost their pest-repelling or confusing properties.Grown

for growth alongside potatoes, it is not really a good idea.The primary reason why it is not a good idea to include brassicas and potatoes in the same growing area is that they do not enjoy the same conditions.The mulches you choose for these plants can be used to influence this factor, and help to prevent problems such as root knot in brassicas and scab in potatoes.The problem will growing

Potato companion plants can also act to create a better growing environment, whether that is providing beneficial shade, ground cover or by breaking up the soil.'Avoid monocultures – where the same type of vegetable crop is grown en masse or in rows – as this makes it much easier for pests and diseases to find their favorite plants and then spread quickly,' says Sue Sanderson.Beans and other legumes are good potato companion plants as they release nitrogen into the soil, which helps improve yields and crop quality.The pungent aroma of garlic and onions is thought to repel some pests and to confuse or distract others, putting them off the scent of the potatoes.Cilantro – or coriander – also attracts beneficial insects, such as ladybugs, hoverflies and wasps, while horseradish is understood to improve the disease resistance of potatoes by producing pest repelling odors and chemicals.Parsley and thyme are believed to be good planting companions for potatoes as they improve the flavor of the tubers, while also attracting beneficial insects, such as hoverflies.'Mint also makes an excellent companion plant as it deters pests, including whitefly, ants and mice, and the flowers attract bees, butterflies and hoverflies,' says herb specialist Jekka McVicar (opens in new tab).Petunias may also protect potatoes from certain pests by confusing them with their strong fragrance so that the insects can't find their target crop.'This may be because they compete for space, light, water, soil nutrients, or attract insects detrimental to the companion vegetables,' says gardening writer and photographer Leigh Clapp.Sunflowers do not make happy planting companions for potatoes as they excrete chemicals that can inhibit seed germination and stunt the growth of crops grown close by. .
