🌱 When to Direct-Sow Verbena Seeds

The key to success is warm soil. Wait until all danger of frost has passed and the soil temperature stays above 65°F (18°C) — typically late spring to early summer depending on your region.

• Zones 5–6: Mid-May through early June

• Zones 7–9: Late April through early May

• Zones 10–11: Early to mid-April

If soil is still cool, Verbena seeds may take longer to germinate or sprout unevenly.

🌿 Choosing the Right Spot

Pick a full-sun location with well-draining soil. Verbena loves heat and light — shaded spots will reduce blooms and make plants leggy.

For garden beds, mix in coarse sand or perlite to improve drainage. For large landscape areas, lightly rake soil before sowing and press seeds in gently without burying them deeply.

🌼 How to Sow Verbena Seeds Outdoors

1. Prepare the soil: Loosen the top 2–3 inches and remove debris.

2. Scatter the seeds: Sow Verbena seeds thinly and evenly across the bed.

3. Lightly press: Do not cover seeds deeply — just press them into moist soil.

4. Water gently: Keep soil lightly moist until germination (4–7 days).

5. Thin seedlings: Once true leaves form, thin to 10–12" apart for even growth.

💡 Pro Tip: Use floating row covers early on to keep birds and pests from disturbing young seedlings.

🌸 Feeding & Watering

• Fertilizer: Apply a balanced slow-release fertilizer at planting or use liquid feed at 100–125 ppm N once seedlings establish.

• Watering: Keep evenly moist but never soggy. Once mature, Verbena is drought-tolerant.

For best bloom, water deeply every 5–7 days during hot periods and remove spent blooms regularly.
