Product Description
Berry Tunnels for Strawberries, Blueberries & Soft Fruit
A berry tunnel is a semi-open, hot-dip galvanized steel structure that shelters soft fruit — strawberries, blueberries, raspberries and blackberries — from heavy rain, hail and harsh sun. Roll-up side walls provide continuous natural ventilation without mechanical cooling, helping limit rain-induced fruit rot. A polytunnel for berries can be set out on sloping or uneven ground without full site levelling.
Why Grow Soft Fruit Under a Tunnel
Berry crops lose marketable yield to weather. Rain on ripening fruit drives splitting and botrytis, hail bruises, and strong sun scorches. A berry tunnel keeps the canopy covered while the sides stay open, so air moves through the planting and foliage dries faster than under a sealed house. Growers use it to protect fruit quality and lengthen the picking window rather than to control the whole environment.

Berry Crops & Nursery Use
The same frame serves several high-value plantings. Covering and ventilation are chosen for the crop, so one layout can carry different varieties across the season.
| Crop | Why a tunnel helps |
|---|---|
| Strawberry | Keeps rain off ripening fruit, reducing splitting and fruit rot |
| Blueberry | Shields blossom and berries from hail and heavy rain |
| Raspberry & blackberry | Protects canes and soft fruit, and keeps picking conditions workable |
| Nursery / seedlings | Net-covered hoops give shade, airflow and pest exclusion for young plants |

Protecting Fruit Quality
Heavy rain. UV-stabilized film sheds water away from the rows, so fruit stays drier and splitting and botrytis pressure fall at harvest time.
Hail and wind. The covered arch takes the impact of hail and gusts that would otherwise bruise or scar soft fruit.
Harsh sun. Film or netting reduces direct exposure on berries during hot spells without sealing the crop in.
Humidity. Roll-up side walls let moist air escape, keeping the canopy ventilated and limiting the conditions that drive fruit rot.

Installation on Uneven Ground
 Screw-pile foundation being installed. | Berry fields are rarely perfectly flat. Because each bay repeats the same arch, the frame can follow the existing ground contour without full site levelling. Screw-pile foundations can replace a poured concrete base where soil conditions allow. Our engineering team confirms the foundation, covering and roll-up ventilation after reviewing wind exposure and local requirements for each project. |
Frequently Asked Questions
Which berry crops are best suited to tunnel growing?
Strawberry and raspberry are the most common, followed by blueberry and blackberry. The same frame also suits nursery and seedling production with netting. Covering and side ventilation are set to the crop and the local climate.
How does a berry tunnel reduce rain-induced fruit rot?
The film canopy sheds rain away from the rows so ripening fruit stays drier. Roll-up side walls then let humid air escape, which limits the damp canopy conditions that favour botrytis and splitting.
Do berry tunnels need fans or mechanical cooling in hot weather?
No. The semi-open design relies on roll-up side walls for natural ventilation, so heat and moisture leave the canopy without powered equipment. This is one reason the structure suits large field plantings.
