🌱 How to Care for Slender Vervain to Prevent Thrips?

💧 How to Water

Water deeply about once a week during the growing season; once established, Verbena rigida tolerates dry spells well and prefers to dry out between waterings. Avoid soggy, poorly drained soil, which encourages root rot.

☀️ Lighting

Give it at least 6 hours of direct sun daily. Full sun produces the densest flowering and sturdiest sandpaper-textured foliage; part shade leads to leggy growth and fewer blooms.

🪴 Ideal Soil

Adapts to sandy, loamy, clay, or chalky soils as long as drainage is good. Aim for neutral to slightly alkaline pH; heavy, waterlogged soil is its main enemy.
