🌱 How to Care for Woodland Sage to Prevent Thrips?

💧 How to Water

Water every 14 days during establishment; mature plants are drought-tolerant and often survive on rainfall alone in temperate climates. Always allow soil to dry completely between waterings. Overwatering causes root rot.

☀️ Lighting

Requires full sun—at least 6 hours of direct sunlight daily. More sun equals more flowers and sturdier stems. Tolerates partial shade but flowering will be reduced.

🪴 Ideal Soil

Prefers average to lean, well-drained soil with a pH of 6.0–8.0. Sandy or gravelly soils are ideal. Rich soil promotes excessive foliage at the expense of blooms. Never plant in waterlogged or clay-heavy ground.
