Avoid planting near agastache or potatoes. It is said that planting 3 or 4 icicle radishes around the mound where you plant squash, and allowing them to grow and bloom, will prevent most pests of squash and cucumber.
Rosemary — Rosemary is a good companion for beans, Brassicas, and carrots. Rosemary repels cabbage moths, Mexican bean beetles, and carrot rust flies. Rudbeckia - All varieties of Rudbeckia are attractive to hoverflies and parasitoid wasps.
Rye — Fall rye gives off a chemical that inhibits the germination of weed seeds. This is known as allelopathy. Planted twice in a row, it can choke out several tough weed species for good. It produces masses of useful organic matter for tilling under or adding to the compost. Do not, however, plant it near cucumbers, which are sensitive to aromatic herbs.
Scabiosa - This plant is naturally attractive to hoverflies and predatory tachinid flies, making it very useful for pest control in organic companion planting. Spinach — A good companion for Brassicas, eggplants, leeks, lettuce, peas, radish, and strawberries, particularly.
Squash — Companions: corn, lettuce, melons, peas, and radish. Avoid planting near Brassicas or potatoes. Borage is said to improve the growth and flavour of squash. Marigolds and nasturtium repel numerous squash pest insects.
Strawberry — These little plants respond strongly to nearby plants. Couple them with beans, borage, garlic, lettuce, onions, peas, spinach, and thyme.
Avoid Brassicas, fennel, and kohlrabi. Summer Savory — This herb attracts honeybees, and repels cabbage moths. Planting it near beans and onions will improve the flavour of both.
Sunflower — Sunflowers planted near rows of corn are said to increase yields. Use sunflowers as beacons to attract pollinators to other crops, particularly squash and pumpkins, and any other crop that requires insect pollination. Sunflowers are attractive to a host of wild and domestic bees, and also ladybird beetles, which prey on aphids.
Swiss chard — Beans, Brassicas, and onions make the best companions for chard. Thyme — An all around beneficial plant for the garden, thyme is particularly worth planting near Brassicas as it repels cabbage moths , and strawberries, as it enhances flavour. Tithonia - Plant this so-called Mexican Torch to attract parasitoid wasps, parasitic flies, and soldier bugs to your garden.
They will act as a beacon for natural pest control. Tomatoes — Another sensitive plant when it comes to companions, tomatoes benefit from asparagus, basil, beans, borage, carrots, celery, chives, collards, cucumber, garlic, lettuce, marigold, mint, nasturtium, onion, parsley, and peppers.
Avoid planting alongside Brassicas and dill. Potatoes may spread blight to tomatoes, so keep them apart. Do no plant tomatoes near walnut trees. Turnip — Turnips are easygoing, but benefit from mint and pea companions. Vetch — Vetch has long roots that fix nitrogen in the soil, and provide masses of organic matter for tilling under. Do not let vetch go to seed, as it will come back strongly.
The seeds are toxic to chickens. Yarrow — Its scent repels aphids, but attracts hoverflies, lady beetles, and wasps that prey on garden grubs. The leaves and stems of yarrow contain enzymes that break down rapidly, so it can be added to the compost raw or as a tea to accelerate the heap. This differs according to the context. Plants that are said to repel pest insects need to be planted quite close to the crops they are meant to protect.
But plants like dill, that are generally attractive to predatory insects, can be planted anywhere in the garden. Meanwhile, when it comes to soil chemistry an example would be Brassicas and potatoes the acidic soil that potatoes thrive in can cause problems for some Brassicas. Damp, acidic soil can host club root for example , which can be a real problem for broccoli and Brussels sprouts. So a long row of potatoes next to a long row of broccoli is not recommended.
By practicing routine Crop Rotation, the right soil conditions can be maintained for the right crops, and soil borne diseases can be avoided altogether.

Thanks for your potato growing article. I have just begun to harvest my early crop of potatoes, I tried it in pots which didn't turn out so well, about 2 decent sized potatoes per pot yukon golds which don't yield much anyway but lots of tiny potatoes which would make great seed potatoes.
My question is can I replant those right now for a second harvest or do potatoes need chill hours before they will sprout again?
I have not been able to find the answer to this anywhere on the internet so please reply : Thank you! The growing period is spring to summer, when the soil and air are cool.
You can save some spuds to plant next season; be sure they are free of disease. I've never heard they need a chilling time, so I don't think so. I recommend you give it a shot, nothing to lose. But, you'd still get something, I'm sure. How high can I continue to hill redskin potatoes.
When should I stop if at All? I am growing potatoes mostly for "new" potatoes. My plants have just started to flower. Should I stop watering them? How long do I wait to harvest them? Thank you! If I were to dig at 8 inch deep hole by 6 inches wide and then plant the potato which is then covered by 3 inches. How do you keep the trench from filling up with water when it rains since there is only 3 inches covering the potatoes?
However, if your soil is more on the clayey side and it looks like it will be very rainy when you intend to plant potatoes, plant them in a shallower trench 5—6 inches deep and fill the trench completely at planting time to keep water from pooling. Be sure to still add more soil over top of the plant as it grows. I planted my potatoes a week ago and did the trench method. A few days later, we got soaking rains and the trenches filled with water and it sat like that for the next day. It's drained since but it's still extremely wet and there's more rain in the forecast.
Would you suggest digging up the potatoes and using another method for planting, filling the trenches with soil, or something else? Skip to main content. You are here Gardening » Growing Guides. Planting, Growing, and Harvesting Potatoes. By The Editors. When to Plant Potatoes Potatoes prefer cool weather. To avoid frost, consider starting potatoes 0 to 2 weeks after your last spring frost. You may plant earlier, as soon as soil can be worked, but be aware that some crops may be ruined by a frost or overly wet soil.
The soil should also not be so wet that it sticks together and is hard to work. Let it dry out a bit first. Choose a location that gets full sun—at least 6 hours of sunlight each day.
Grow potatoes in rows spaced about 3 feet apart. With a hoe or round-point shovel, dig a trench about 6 inches wide and 8 inches deep, tapering the bottom to about 3 inches wide. Spread and mix in fully-rotted manure or organic compost in the bottom of the trench before planting. Learn more about soil amendments and preparing soil for planting.
How to Plant Potatoes In each trench, place a seed potato piece cut side down every 12 to 14 inches and cover with 3 to 4 inches of soil. If your garden soil is very rocky, put the seed potato pieces directly on the ground.
Sprinkle with a mix of soil and compost. Cover them with straw or leaves, hilling the material up as the potatoes grow. The best starters are seed potatoes. Do not confuse seed potatoes with potato seeds or grocery produce! Select seed potatoes which have protruding eyes buds. Use a clean, sharp paring knife to cut large potatoes into pieces that are roughly the size of a golf ball, making sure that there are at least 2 eyes on each piece.
If you are cutting up potato pieces yourself, do so 1 to 2 days ahead of planting. After the potato plants have emerged, add organic mulch between the rows to conserve moisture, help with weed control, and cool the soil. Check out this excellent video to see how to plant potatoes. How to Grow Potatoes Hilling Potatoes A critical part of growing potatoes is to not let their tubers i. To combat this, we employ a technique called hilling.
Tips for growing and hilling potatoes: Do the hilling in the morning, when plants are at their tallest. During the heat of the day, plants start drooping. Maintain even moisture, especially from the time when sprouts appear until several weeks after they blossom. The plants need 1 to 2 inches of water per week.
If you water too much right after planting and not enough as the potatoes begin to form, the tubers can become misshapen. The last hilling should be done before the potato plants bloom, when the aboveground part of the plant is at least a foot tall. Hoe the dirt up around the base of the plant in order to cover the tubers as well as to support the plant. Plants that fit this description include: Beans Legumes While potatoes do not generally like to compete with other root crops, horseradish is actually considered an excellent companion plant for potatoes.
