Description
The potato is the most productive tuber in the home garden and a grateful soil loosener in the crop rotation. One seed tuber turns into a whole bucketful by harvest, a classic that children enjoy too.
Care instructions
Lay the pre-sprouted tubers from April about a hand's width deep into loose soil and hill the plants up as soon as they are 20 cm tall; that protects the tubers from light and greening. Keep them moist in dry spells; harvest once the foliage has died back.
Soil & site

Soil type
sandy, loamy, humus-rich, well-drained, nutrient-rich
Feeding
Heavy feeder
Companion planting
Good neighbors
asparagus family (Asparagaceae)
particularly well establishedAsparagus and tomato benefit from each other. The tomato keeps the asparagus beetle away, and the asparagus repels threadworms that harm the tomato.

mint family (Lamiaceae)
particularly well establishedYou will find that basil next to tomato and pepper improves taste and keeps whiteflies and aphids away.

borage family (Boraginaceae)
Borage attracts pollinators and is supposed to keep tomato pests away from the nightshade family.

Rather not
amaryllis family (Amaryllidaceae)
Onions slow down the growth of nightshade family plants next to potatoes and tomatoes; the classic crop-rotation rule also applies in the bed side by side.

daisy family (Asteraceae)
Sunflowers release substances into the soil that inhibit potato tuber growth, and they also compete for water and nutrients.

gourd family (Cucurbitaceae)
You should avoid planting potato and cucumber together because they share disease pathogens such as leaf and brown rot and stand in each other's way as strong feeders.
