USA High Tunnel for Eggplant Growing
A high tunnel for eggplant works well in warm climates where temperatures rarely drop below 59°F. Overhead cover reduces fruit sunscald, the main cosmetic defect causing market rejection, and protects against rain that triggers anthracnose. It is the ideal structure for growers who want to improve eggplant quality without the full investment of a closed greenhouse.
Technical Specs
Ideal Temperature
68 to 86 °F
Relative Humidity
60 to 75%
Crop Cycle
120 to 180 days
Yield vs Field
2 to 3×
Sunscald eliminated
Diffuse plastic reduces direct radiation that causes bronze patches on eggplant fruit surface, improving the percentage of first-grade marketable fruit.
Anthracnose protection
Overhead cover prevents rainfall that activates Colletotrichum spp. on ripe fruit, reducing post-harvest rot by up to 50%.
Harvest 2-3 weeks earlier
The warmer high tunnel microclimate accelerates the eggplant cycle, allowing market entry before open-field production from the same region.
Agronomist Tip
Place blue sticky traps from transplant day in eggplant high tunnels, thrips is the vector of Tomato spotted wilt virus (TSWV) that also attacks eggplant severely, and there is no cure once the plant is infected.
