Yukon Chief Sweet Corn

Yukon Chief Sweet Corn is one of the earliest varieties of corn. During good conditions, Yukon Chief is ready to eat in only 55 days. Golden yellow ears around 15cm long with a traditional sweet corn flavor. Sturdy dwarf plants reach around 100cm.  Germinates and grows well also in cooler soils. Developed at the University of Alaska, released in 1958. 20seeds/pack.

Normally corn grows to the height of 180cm. But higher varieties up to over 250cm occur. Dwarf varieties only around 60cm can also be grown in pots. Sweet corn is harvested when the silky threads are starting to wilt and the cobs are full and chubby. Popcorn, Flour corn, and Dent corn are harvested when they are completely mature and dry. If you live in an area with wet autumn you can harvest the cobs and hang them indoors for drying. When they are completely dry, they can be popped or ground into flour.

How to Grow

Corn can either be sown directly in the ground or cultivated indoors before planting the seedlings in the garden. The choice of method depends on your growing conditions and the variety of corn being grown. If you farm in a warmer area with a long summer season, sowing directly in the garden will save you a lot of work. If the season is too short in your area, you will risk not getting any harvest. If you are farming in a short-season area you can sow indoors and will "save time" by having plants some weeks old, ready for planting when the risk for frost is over. You can also choose a variety with a shorter development time. Some varieties are ready in only 55 days. 

If you sow indoors, use sterilized potting soil. Sow about 4cm deep. It is better to use deep pots instead of wide pots. Corn grows fast, so don't sow too early. About 4-6 weeks before planting is reasonable. Place at 25°C during germination. After sprouting, lower the temperature to avoid lanky plants. You might have to re-plant the seedling once or twice, depending on the pot size. Corn can not stand being affected by frost, so do not plant outdoors before the risk of frost is over. If you direct sow the temperature of the soil must be over 15°C, otherwise the seeds will rot. Plant the seedlings with 20-40cm spacing, depending on the variety.
