Lisianthus Spacing Guide for Cut Flower Production: Field vs High Tunnel + Netting Setup for Strong, Straight Stems
Share
🌸 Why Spacing Matters for Lisianthus Cut Flower Production
Lisianthus is one of the most valuable cut flowers you can grow, but spacing plays a major role in determining your results. Proper spacing directly impacts:
- Stem length and strength
- Bloom size and quality
- Airflow and disease prevention
- Yield per square foot
Spacing too tight can lead to weak stems and disease pressure, while spacing too wide reduces your total production. Finding the right balance is key to producing premium, market-quality stems.

🌾 Field Spacing for Lisianthus (Outdoor Production)
Growing lisianthus in the field requires spacing that supports airflow, plant health, and strong stems.
✅ Recommended Field Spacing:
- 6” x 6” → high-density production
- 6” x 8” → best overall balance
- 8” x 8” → premium stems, larger plants
🔥 Best Overall Choice:
👉 6” x 8” spacing
This provides:
- Strong stems
- Good airflow
- Efficient use of space
- Lower disease risk
🌿 Field Bed Layout
Most growers use:
- 3–5 rows per bed
- 30”–36” bed width
- 12”–18” walkways
This layout allows easy harvesting while maximizing plant density.
🌱 High Tunnel Spacing (Professional Production)
High tunnels allow for tighter spacing because conditions are controlled.
✅ Recommended High Tunnel Spacing:
- 4” x 6” → high production density
- 6” x 6” → standard professional setup
- 6” x 8” → premium stems
🔥 Best Setup:
👉 6” x 6” spacing
This gives:
- High yield per square foot
- Strong stems
- Consistent growth
🌡️ Why High Tunnel Spacing Works Differently
In a tunnel, you control:
- Temperature
- Irrigation
- Airflow
This allows plants to grow closer together with less disease pressure compared to field production.
🌸 Netting Lisianthus for Straight, Market-Ready Stems
Netting is one of the most important steps in lisianthus production.
Without support, plants will:
- Fall over
- Bend
- Produce unusable stems
🕸️ How to Net Lisianthus Properly
Use:
- Flower support netting (Hortonova style)
- 6” x 6” or 6” x 8” grid
Setup Layers:
- First layer at 6–8 inches
- Second layer at 12–18 inches
- Third layer for taller varieties if needed
👉 Plants grow through the netting, keeping stems straight and supported.
🔥 Pro Tip
Install netting early—before plants start leaning.
🌿 Field vs High Tunnel Netting
Field Growing:
- 2–3 layers recommended
- Strong staking required
- Wind protection is important
High Tunnel Growing:
- 1–2 layers often enough
- Less environmental stress
- More uniform growth
🌱 Spacing vs Yield Strategy
Tight Spacing:
- More stems per area
- Slightly thinner stems
Wider Spacing:
- Fewer plants
- Thicker, premium stems
👉 Many growers use a mix depending on their market goals.

What is the best spacing for lisianthus in the field?
👉 6” x 8” is the best balance for airflow, yield, and stem quality.
What spacing is best for high tunnels?
👉 6” x 6” is the most common professional spacing.
Do lisianthus plants need netting?
Yes—netting is essential for straight stems and market-quality flowers.
How many layers of netting should I use?
Typically 2–3 layers depending on plant height.
What happens if you don’t net lisianthus?
Plants will fall over, bend, and produce lower-quality stems.
Is wider spacing better for premium flowers?
Yes—wider spacing can produce thicker stems and larger blooms.
