Denmark has four hardiness zones, ranging from zone 7a in the northernmost parts of Jutland to zone 8b in the southern islands like Lolland and Falster.
This variation reflects Denmark's maritime climate, which is influenced by its proximity to the North Sea, Baltic Sea, and Gulf Stream.

Denmark generally experiences a temperate maritime climate. Winter temperatures typically range from -4°C to 4°C, while summer temperatures average between 15°C and 25°C.
Extreme weather events can occasionally push temperatures outside these ranges. Understanding these climate patterns is crucial for successful gardening and crop management in Denmark.
Characteristics of Denmark’s Growing Regions
- Maritime climate with mild winters and cool summers
- Winter temperatures usually range from -4°C to 4°C
- Mild summers with average temperatures between 15°C and 25°C
- Consistent rainfall throughout the year, with slightly more precipitation in autumn and winter
- Long summer days due to northern latitude, but short winter days
- Occasional strong winds, especially in coastal areas
The primary growing season in Denmark typically spans 6 to 7 months, from April to October in most regions.
The exact length and timing of the growing season may fluctuate based on the particular region within Denmark and the year-to-year climatic variations.
Challenges of Growing in Denmark
Unpredictable Spring Weather
Danish gardeners often face the challenge of unpredictable spring weather. Late frosts can occur well into May, posing a risk to tender young plants and early crops. This unpredictability requires careful planning and sometimes requires protective measures like row covers or cold frames.
Coastal Wind Exposure
Much of Denmark is exposed to strong winds, particularly in coastal areas. These winds can damage plants, dry the soil quickly, and create a harsher microclimate. Gardeners must often implement windbreaks or choose wind-resistant plant varieties to mitigate this challenge.
Limited Light in Winter Months
Denmark's northern latitude results in very short days during winter months. From November to February, daylight can be limited to 7-8 hours daily, significantly restricting plant growth. This shortage of natural light can be a significant hurdle for year-round cultivation, especially for light-loving crops.
The Benefits of Using a Greenhouse in Denmark
Utilizing a greenhouse in Denmark offers gardeners a powerful solution to navigate the country's variable maritime climate.
Greenhouses provide a sheltered environment, lengthening the growing period, shielding plants from harsh North Sea winds, and boosting overall yield throughout the seasons.
Extend Your Growing Season
- Without a greenhouse:
The outdoor growing season in Denmark typically spans 6 to 7 months, from April through October in most regions. This period can limit cultivating heat-loving vegetables that thrive in warmer climates.
- With a greenhouse:
Greenhouses in Denmark can dramatically extend the growing season, often enabling cultivation from late February through November or even year-round for specific crops. This controlled setting protects plants from unexpected late frosts and provides a stable growing environment despite Denmark's frequently changing weather patterns.
Grow a Wider Variety of Vegetables
- Without a greenhouse:
Danish gardeners typically focus on cool-season and wind-tolerant vegetables for outdoor cultivation to adapt to the maritime climate. Some suitable options include:

- With a Greenhouse:
A greenhouse in Denmark allows for a significantly expanded range of vegetables to be grown throughout the year. Some examples of vegetables that flourish in Danish greenhouses include:
