Help your August plant grow big and strong.

Here´s what´s ahead:

Getting started

Radishes are the perfect plants for beginners! They grow quickly, thrive in a vegetable patch, but also in a balcony box, and they are tasty and healthy. You can sow radishes on the windowsill from February to September. Direct sowing outdoors (balcony or bed) is possible from March to August. By the way, the fast-germinating radishes help you to mark slow-germinating vegetable plants in your bed. For example, if you sow radish seeds in the same row as carrot seeds, the radishes will shoot out of the soil and show you where it is better not to weed.

The most important information at a glance:

  • Germination depth: 0.5 - 1 cm

  • Temperature: 12 - 15 °C

  • Germination period: 5 - 10 days

  • Sowing indoors: February - September

  • Relocate outdoors: from March

  • Direct sowing outdoors: March - August

  • Harvest radish/seeds: April - October/September

  • Plant spacing: 5 cm

  • Root depth: 15 cm

  • Location: sunny

  • Nutrient requirements: low


Sowing in a pot:

  • Sowing on the windowsill is possible as early as February. From March on you can take the pots outside or sow your seeds directly on the balcony.

  • Fill pots or balcony boxes with all-purpose soil and make holes (1 cm deep, 5 cm apart) in the soil with your finger.

  • Take the seed paper from your calendar and tear it into small pieces.

  • Spread the pieces (one seed per hole).

  • Cover the seeds with a thin layer of soil (approx. 0.5 - 1 cm).

  • Place the pots on a bright windowsill.

  • Keep the soil moist until the seedlings start to sprout.

Direct sowing outdoors (balcony or bed):

  • From March to August, you can sow the seeds directly outside.

  • Make grooves in your vegetable patch with a spacing of 15 cm.

  • Tear your seed paper into small snippets.

  • Spread the seed shreds in the rows at a distance of 5 cm.

  • Cover the seeds with a thin layer of soil (approx. 0.5 - 1 cm).

  • Moisten the soil regularly.

  • If the seedlings grow too close together, you will have to thin them out (remove some of the weaker plants) so that the others can continue to grow well.



  • Sunny

  • Soil: rich in humus and loose

  • Good neighbours: bean, pea, strawberry, cabbage, lettuce, carrot, pepper, lettuce, radish, salsify, spinach

  • Bad neighbours: cucumber, mustard, onion


  • Water regularly, especially during dry periods.

  • Fertilizing is not necessary

  • Loosen soil regularly with a cultivator or hoe

Diseases and pests

  • Ground fleas: as a preventive measure, loosen the soil regularly and keep the soil moist.

  • Cabbage flies: put up protective nets as a preventive measure.

  • Aphids: if infested, release beneficial insects (e.g. lacewing larvae) or spray with diluted neem oil.

Harvest & Storage

  • Harvest about 4 - 8 weeks after sowing.

  • Harvest the radishes earlier rather than later, older tubers can taste woody.

  • Best used right after harvesting.

  • Wrapped in a damp cloth, they can be stored in the fridge for a few days.



  • Spicy flavour and beautiful reddish colouring that adds a splash of colour to your plate.

  • Perfect with salads and sandwiches

  • Contains lots of vitamin C
