Why Grow Verbena from Seed?

Growing Verbena from seed gives growers more control over timing, cost, and variety selection compared to cuttings. With modern hybrid genetics, seed-grown Verbena now matches cutting-grown varieties for vigor, flower count, and color stability.

Top reasons to choose Verbena seeds:

• Consistent germination and plug uniformity

• Short crop time (6–7 weeks plug production)

• Excellent branching and trailing habit

• Adaptable for both upright and hanging basket types

• Strong garden performance and heat tolerance

For detailed plug production insight, see How to Grow Bacopa Seeds for Professional Plug Production | Nursery-Grade Tips — its moisture management and plug care parallels Verbena perfectly.

Professional Greenhouse Growing Conditions

Germination Stage (Days 1–7)

• Temperature: 73–76 °F (23–24 °C)

• Light: Not required for germination

• Moisture: Level 3 (moist, not wet)

• pH: 5.5–5.9  EC: 0.5–0.75 mS/cm

• Tray Size: 288-cell trays, one seed per cell

Water evenly but sparingly to avoid damping-off. Verbena prefers a slightly drier medium during early germination for better root initiation.

---

Plug Stage (Weeks 2–6)

After emergence, increase airflow and provide strong, consistent lighting:

• Temperature: 68–70 °F (20–21 °C)

• Light Duration: 14 hours per day for compact plants

• Light Intensity: 3,500–4,500 foot-candles

• Fertilizer: 75–125 ppm N

• Moisture Cycling: Alternate between Levels 3 and 4

Verbena plugs should be firm and well-rooted at transplant. Avoid stretching by maintaining proper light levels and spacing.

Container & Basket Finishing

Once transplanted, Verbena finishes rapidly under warm, bright conditions:

• Temperature: Day 70–72 °F / Night 64–66 °F

• Light: 4,000–6,000 ft-candles

• Media pH: 5.8–6.2  EC: 1.5–2.1 mS/cm

• Fertilizer: 125–175 ppm N

PGRs:

• Bonzi® drench at 1–3 ppm or B-Nine® spray at 3,500–5,000 ppm as needed.

Lighting & Growth Uniformity

Verbena thrives under long days — 14+ hours ensures early and even flowering. Supplemental lighting during short-day months is critical for high-quality blooms.

Use LEDs or HID lights to maintain a Daily Light Integral (DLI) of 12–14 mols/day. Verbena grown under high light will have tighter internodes, better branching, and stronger color saturation.

Disease & Pest Prevention

Common pests: Thrips, spider mites, and aphids.
Common diseases: Powdery mildew, Pythium, Rhizoctonia, and Tospovirus (TSWV).

Prevention tips:

• Start scouting early for thrips.

• Maintain moderate humidity and consistent airflow.

• Avoid wet foliage at night.

• Use preventative drenches for root diseases.
