Spring onions are a delicious ingredient in hearty dishes and salads. The culture is uncomplicated, because the plant turns out to be grateful and undemanding. Since it is a perennial, you can harvest the fresh leaves over several years.
Spring onions can be topped up
Plant early seedlings
Spring onions can be grown in planters from spring to autumn. If the young plants are strong enough, they can move outdoors in late summer. You can plant spring onions on harvested beds, because they get along well with the available nutrients. The planting is done in double rows with a distance of five centimeters, whereby there should be a distance of 2.5 centimeters between the plants. The next double row is about 30 to 40 cm away.
Set split instances
The spring onions grow in clumps, with the individual clumps consisting of several shoots. These can be dug up and shared. Make sure that each section has at least three shoots. Place the plants in the bed at a sufficient distance from each other. This allows you to multiply a plant continuously, so you don't have to sow spring bulbs.
Let the spring onions grow back
Purchased spring onions are perfect for breeding, even if the roots have dried up. Harvest the green parts of the plant and leave a shoot about three to five centimeters long on the white root tuber. This forms the basis for propagation.
water glass method
Place the root in a glass of water and change it after 48 to 72 hours. Fresh shoots appear after a few weeks, which you can harvest continuously. Since this hydroponic culture does not provide sufficient nutrients, the lifespan in the glass is limited. After two to three harvests, the plant is exhausted.
earth method
The harvest will be more productive if you plant the onion bulbs in the ground. A plant pot or the garden bed is suitable for further cultivation. The perennial spring onion sprout and in this way provides fresh supplies every two to three weeks.
