USA High Tunnel for Swiss Chard Growing
A high tunnel for chard is a practical, economical solution for growers who want to improve product presentation without the investment of a greenhouse. Rain and hail protection eliminates physical leaf damage, the main quality degradation factor in field-grown chard. In temperate climates with moderate rainfall, a high tunnel captures most of the greenhouse benefits for this crop.

No physical leaf damage
Rain and hail tear and stain chard leaves which are fragile, a high tunnel eliminates damage that degrades product from first to second grade.
Very low installation cost
For chard, a simple high tunnel structure provides adequate protection with minimal investment recovered in 1-2 production cycles.
Cold season cycle extension
The warmer tunnel microclimate protects chard from light frost that can burn outer leaves and make the product unmarketable.
Agronomist Tip
Stagger chard plantings every 15 days in high tunnels to maintain continuous harvest, concentrating all production in one period collapses local prices and wastes the competitive advantage of protected cultivation.
