Polytunnels
Protected cultivation in polytunnels ensures a high level of harvest reliability and excellent fruit quality. Depending on the region, protected cultivation allows for the first harvests as early as late April or early May. The extended harvest season is an additional advantage, especially for direct-sales operations, as it helps build customer loyalty.
Advantages of protected cultivation:
• Longer harvest season
• Consistent yields and high value added per unit area
• Work processes, sales, and distribution are easier to plan
• Low disease pressure, resulting in reduced need for plant protection
• High proportion of Grade 1 fruit
Consider the following when planning:
- Watering options
- Place in a location that is as sheltered from the wind as possible
- Investment costs
- Lead time for planting and installation
