Double Standard, organic seeds



Sweet Corn. Is a traditional, early, openly pollinated sweetcorn of 2 colours. It germinates better in cool soil than most sorts and is unaffected by less than fortunate weather in May. The cobs vary a little but are usually 17 cm long with 12 rows of yellow and white grains of corn. Completely yellow cobs do occur occasionally. Double Standard is an excellent sort which is tastier and crispier than average. If you save ripe seeds yourself you can get completely white, early corn, if you sow only the white ones. A portion contains about 30 seeds.

Cultivation advice


Sow indoors or in a hotbed, about 4 cm deep, 4-6 weeks before planting outdoors and keep a temperature of around 25°C during germination. Lower the temperature after sprouting to prevent lanky seedlings. If the seed was scattered, pot on the plants to separate pots, when they have grown 5-10 cm tall.
Corn is affected by frost, so do not set out the plants outdoors until the risk of frost is over and the soil has warmed up. Corn can be sown directly outdoors in southerly, warm places in Central Sweden. The temperature of the soil must be at least 15°C otherwise untreated seeds will rot. Covering with fibre-cloth before and during sprouting raises the temperature a few degrees.


Keep 20-30 cm between the plants and 70-80 cm between the rows or cultivate in double rows of 10-15 cm between every second row.


Sweet Corn is ready for harvest when the silky threads have wilted, the cobs grown thick and blunt and the seeds are pale yellow. When pressing a nail into a grain of corn a somewhat viscous, milk-white juice emerges. Poach the cobs immediately and enjoy! They can also be frozen or preserved. 


Normally 3-5 seeds/g one portion yields 20-25 excellent seedlings for setting out. 200 g sows 100 m.  
A portion contains about 30 seeds.
