Winter Growing and Season Extension

Master the key methods and techniques to grow high-quality produce efficiently year-round, even in a nordic climate.

Having a year-round offering is possible!

Many small farms in northern climates have to deal with the stress of having to generate all of their annual revenue during the warm summer months. This reality often causes people to work tirelessly and burn out, but it does not have to be this way. In the past few years, customers’ expectations have changed and we have seen a rapid increase in the demand for fresh, local produce during the winter. Customer demand is so high that farms offering diversified crops during the winter often struggle to meet the demand – even if products are priced at a premium. By applying winter production and season extension techniques, farms can generate extra income that can reduce stress and contribute to a better quality of life and a more sustainable business.
