What Is High Tunnel Production?
A high tunnel is an unheated structure covered with greenhouse plastic that protects crops from rain, wind, and temperature extremes while allowing growers to extend the growing season.
Unlike heated greenhouses, high tunnels rely primarily on sunlight for warmth while providing a much more stable growing environment than open fields.
Many commercial flower farms now produce Lisianthus almost exclusively in high tunnels.
What Is Field-Grown Lisianthus?
Field-grown Lisianthus is planted directly outdoors once the danger of frost has passed.
With proper soil preparation and irrigation, field production can produce beautiful flowers while reducing infrastructure costs.
For growers with large planting areas, field production remains an excellent option.
Earlier Harvest
High Tunnel
One of the biggest advantages of high tunnels is earlier production.
Protected plants:
- Warm faster in spring
- Grow more consistently
- Reach flowering sooner
- Often produce marketable stems weeks before outdoor crops
Earlier flowers often command higher prices at local markets.
Field Production
Outdoor production depends entirely on weather.
Cool springs, heavy rain, and fluctuating temperatures can delay flowering compared to protected growing.
Stem Quality
High tunnels usually produce:
- Straighter stems
- Longer stems
- Cleaner foliage
- Better overall presentation
Because plants are protected from heavy rainfall and strong winds, stem damage is greatly reduced.
Field-grown plants can still produce excellent stems but are more affected by weather conditions.
Disease Pressure
High tunnels provide protection from rain, reducing splash-borne diseases on foliage and flowers.
However, growers must monitor:
- Humidity
- Air circulation
- Ventilation
Without proper airflow, fungal diseases can still develop.
Field production often has better natural airflow but greater exposure to prolonged rainfall, which can increase disease pressure depending on the season.
Water Management
High Tunnel
Most growers use drip irrigation, allowing precise watering while keeping foliage dry.
This promotes healthier plants and reduces many disease problems.
Field Production
Outdoor crops rely on rainfall plus supplemental irrigation during dry periods.
Too much rain can occasionally reduce flower quality or slow harvesting.
Flower Quality
High Tunnel Lisianthus often produces:
- Larger blooms
- More uniform flowers
- Cleaner petals
- Better color development
- Premium florist quality
Field-grown Lisianthus still produces beautiful blooms but may experience occasional weather-related imperfections.
Production Costs
Field production generally costs less because no permanent structure is required.
High tunnels require an initial investment but often repay growers through:
- Earlier harvests
- Higher-quality stems
- Extended production
- Greater market value
Many commercial flower farmers find the investment worthwhile over time.
Which Method Is Best?
Choose High Tunnel Production if you want:
- Earlier flowers
- Premium stem quality
- Better weather protection
- Extended harvest season
- Professional cut flower production
Choose Field Production if you want:
- Lower startup costs
- Larger planting areas
- Simple production methods
- Excellent outdoor performance
Many experienced growers use both systems to spread production across the growing season.
Don't Forget Companion Flowers
Many flower farmers grow Snapdragon Chantilly Mix alongside Lisianthus because Snapdragons bloom earlier and create beautiful bouquet combinations.
Together, these premium cut flowers provide continuous harvests and stunning floral arrangements.

Final Thoughts
Both high tunnel and field-grown Lisianthus can produce spectacular flowers.
If your goal is premium florist-quality stems, earlier harvests, and greater protection from unpredictable weather, high tunnels provide significant advantages.
If you're working with larger acreage or keeping startup costs low, field production remains an excellent choice that can still produce beautiful, marketable blooms.
Many professional flower farmers combine both growing methods to maximize production throughout the season while reducing weather-related risks.
No matter which system you choose, starting with quality seed, healthy plugs, fertile soil, and consistent care will reward you with some of the finest cut flowers you can grow.
Frequently Asked Questions
Is a high tunnel better than growing Lisianthus in the field?
For premium cut flower production, many growers prefer high tunnels because they offer earlier harvests, straighter stems, and protection from harsh weather.
Can Lisianthus grow well outdoors?
Yes. Lisianthus grows very well outdoors in fertile, well-drained soil with full sun and consistent watering.
Does a high tunnel reduce disease?
It can reduce diseases caused by rainfall, but proper ventilation is still essential to prevent humidity-related fungal issues.
Which method produces longer stems?
High tunnel production generally results in longer, straighter stems that are ideal for florists and bouquet production.
Is field production less expensive?
Yes. Growing directly in the field usually requires a lower initial investment than building a high tunnel.
Can I grow Snapdragons with Lisianthus?
Absolutely. Many flower farmers grow Snapdragons and Lisianthus together because they bloom at different times and create beautiful mixed bouquets.
