Cultivation advice

Sowing

Sow the black seeds about 1cm deep in March-April indoors or in hotbeds. Keep the sowing warm during germination, 20-25°C, preferably. When the seedlings have sprouted put them in a light, airy, cool place. Especially during the last weeks before setting it is important that the temperature not be too high (max. 15°C), because the onions may begin to swell to early believing it to be summer. The plants become sturdier if the foliage is cut now and then to a height of 6 cm. Eat the cut off tops in the same way as spring onion. Set out in a plot as soon as the soil has warmed up a bit and the risk of frost is over. Set the onions shallowly and firmly! Onions develop for a long time and can only be sown outdoors in the southern parts of the country. 

Spacing

Sow 40-60 seeds/meter. Keep a mutual distance of 2-5 cm during pre-cultivation. Keep 10 cm between the plants outdoors and 25-50 cm between the rows! 
Sow 4-500 seeds in a 10 cm wide strip for sets!
250-300 seedlings/m is just about right for growing onion sets.

Harvest

Harvest the onions in dry weather! As soon as the tops of ¼ of the onions have begun to wither and fall, break down the tops of the rest of the onions. Pull them out in a few days and if the weather is dry and mild they can be allowed to remain on the ground for ab. 1 week to dry.  It is, however, safest to place them under a roof in an airy, dry place. You get the best keeping qualities if the onions are allowed to dry in warm air (30°C) for 1 week before trimming and placing them  in a dry, cool space, free of frost.
Onion sets should be harvested when they have grown to 1.5-2 cm in diameter, usually in August. Break down the tops and allow the onions to dry in the same way as the common onions. If the onion sets are kept in an airy and dry place at 30°C the whole winter the risk of bolts and attacks by mildew is small. If that is not possible a day at 40°C directly before setting helps some. Do not choose the big onion sets primarily! The larger onion sets the more bolts.

Seed

200-300 seeds/g, one portion yields 75-100 good seedlings for setting and is sufficient to sow a few meters directly and 20-30 g for 100m.  
A portion contains about 200 seeds.
