The sowing of leek is divided in 2 different groups: summer- and early autumnsowings or late autumn- and early wintersowings. This sowing guide is for the late autumn- and early wintersowing.
Sow indoors from February on. Sow in loose, airy and moist potting soil. Sow in trays and cover the seeds with a thin layer of soil. You can soak the seeds for a better and quicker germination approx. 24 hours prior to sowing in tepid water. Keep moist and warm. Make sure the temperature is as even as possible and don't let the temperature drop during the night. Put the seedlings, outdoors to harden them of by putting them outdoors during the day for 10 - 14 days from the beginning of May, when there's no longer any danger of nightfrosts. After this you can put the seedlings, when they're about as thick and as long as a pencil, outdoors in the soil. Remove 1/3 of the top and 1/3 of the roots to stimulate the growth.
You can sow outdoors under glass from the beginning of April. Sow in trays filled with loose, airy and moist potting soil. Cover the seeds with a thin layer of soil. Further you can do the same as with the indoor sowing.
Sow outdoors from the beginning of April in the soil. Choose a sunny plot with good, loose, airy and moisture retaining soil. Sow thinly and cover the seeds with a thin layer of soil. Keep them approx. 20 cm apart. Put the seedlings, when they're about as thick and as long as a pencil, outdoors on their permanent spot. Remove 1/3 of the top and 1/3 of the roots to stimulate the growth. Put them in a hole approx. 5 cm wide and 10 - 15 cm deep. Keep them approx. 20 cm apart. Pour water in the holes to wash the roots. You need to earth the stems of the leeks up, to maintain a nice white lower part of the stems. Be careful you don't put soil between the leaves of your leeks.
Late autumn- and early winterleek needs a lot of time to grow. Harvest these leeks from the end of July till the middle of May, in the following year. This leek has a good resistance againgst cold and frost and is kept on the land. Harvest the leeks a fresh as possible and use a pitchfork to get them carefully out of the soil. These leeks can be frozen to store.
