Growing Considerations:

Short growing season of approximately 50 – 60 days.
- Consider using a covered or indoor growing facility such as a cold frame or greenhouse to extend the season.
- Consider a black soil cover to thaw soils more quickly in the spring in preparation for planting.
Typically, poor native soil that may be either rocky, poorly drained, or have low inherent fertility.
- Add organic matter and amend the soil specific to your site with the recommended fertilizers and amendments.
Day length due to high latitude can prove challenging and force growers to plan carefully.
- Add lighting or focus on planting in an area that receives maximum sunlight exposure.
