Greenhouse for Kale Growing
Greenhouse kale commands premium pricing in health food, restaurant and specialty grocery markets where clean, unblemished leaves are non-negotiable. A controlled environment prevents the physical leaf damage from rain, wind and hail that degrades field kale to second grade, and allows year-round production independent of seasonal weather. Baby kale and full-size kale both benefit significantly from greenhouse conditions.

Premium clean leaves year-round
Greenhouse cover produces unblemished leaves that meet the strict visual standards of specialty grocers, restaurants and fresh-cut processors.
No seasonal production gaps
Extreme summer heat or winter cold that limits field kale production becomes irrelevant, the greenhouse maintains optimal growing conditions year-round.
Baby kale viability
The controlled environment allows efficient baby kale production with 25-30 day harvest cycles, a high-value product requiring consistent leaf quality.
Agronomist Tip
Harvest outer kale leaves in the early morning when they are most turgid and cool, kale loses moisture quickly at midday temperatures, and leaves harvested in the heat have significantly shorter shelf life regardless of cold chain handling.
