Place the boxes in a bright, frost-free room. A room temperature of 15 degrees Celsius is excellent for forcing.

Note: As an alternative to the seed potatoes offered in stores, you can use organic potatoes. Unlike ordinary table potatoes, these are not treated with sprout stop.


Plant the well germinated potatoes in April or May in the top soil layer of the raised bed.

  • Germination length at planting time: about three to four centimeters
  • Dig 15 centimeter deep holes in bed surface
  • Spacing 20 to 25 centimeters
  • Insert tubers individually into holes with germ upwards
  • Optimal distance to the edge of the raised bed: 10 to 15 centimeters.
  • Finally, cover the tubers with crumbly vegetable or compost soil.

Potatoes belong to the plants that have a high demand for sun, nutrients and water. Only in this way can form large, delicious tubers. Water the raised bed with potatoes best in the early morning hours. Remove weeds regularly and loosen the soil every now and then.

Note: Additional fertilization during the growing season is not necessary.


Potato plants should also be mounded regularly when grown in raised beds. When the first green leaves are visible after four to five weeks, cover the plants completely with soil again. Repeat the mounding every two weeks. In this way, new roots are formed, so that many tubers can be formed. When the top edge of the raised bed is reached, let the plants grow. In this way, in the 40 centimeter thick layer can develop many delicious tubers.


Note: Simply give the raised bed soil to the compost. Together with other materials it becomes new humus again. You can also use the fill as an intermediate layer when building the next raised bed.


Depending on the variety, the potato harvest takes place between July and September. When the leaves wilt, soon is the right time to harvest. Allow the tubers to ripen in the ground for two weeks after the foliage dies.

Very carefully dig the tubers of potatoes out of the raised bed. Use primarily your hands or blunt shovels to do this. Pointed tools can damage the delicious tubers.

Potatoes will keep for several months if protected from light and moisture. Remove coarse dirt from freshly harvested tubers. Choose a dark, cool place in the cellar. The ideal storage temperature is 4 to 6 degrees Celsius. Layer the potatoes in an airy wooden crate. Alternatively, you can use jute bags or canvas bags. If potatoes nevertheless begin to sprout, you should consume them quickly.
