Growing Onions

You can grow onions in different ways. The fastest method is of course using onion bulbs. They can be eaten in the same year. But it is also very nice to start the sowing process from the beginning and grow onions from seeds. There are also onion seeds whose cultivation takes 1 year in total.

Sowing and growing onions

Sow between March and mid-April in rows 25 cm apart and about 5 mm deep. Thin out later so that the plants are about 5-10 cm apart.

Planting onion sets can be done in March and April with a planting distance of 25 x 10 cm. Store the onion sets in a cool and dry place before planting out.

Location and soil

For the cultivation of all types of onions, a loose soil structure, rich in humus and evenly moist, promotes growth. Onions prefer a sunny, warm spot.
