Gardening in the arctic and subarctic requires a knowledge of what techniques are needed to increase the chances for success. The two main differences that affect gardening encountered in the far North are cold soils and long days. Because planting begins late, usually the end of May or the first of June, the days' length is already very long and all the varieties Denali offers are not adversely affected by those long days. Our proven varieties, along with soil-warming techniques, are needed to assure success in the far North. The most common soil-warming techniques used are

1. the use of clear plastic fence as a windbreak to reduce the cooling effects from soil evaporation,
2. raised beds and raised rows to expose more of the soil's surface to the sun, which will result in quicker warming,
3. a clear plastic ground cover over the row area, which will provide a "greenhouse effect" with trapped superheated air, which will increase soil warming.
