ðŸŒą How to Care for Lavender to Prevent Grey Mould?

💧 How to Water

Water lavender deeply but infrequently, approximately every 10–14 days during the growing season. Allow the soil to dry out completely between waterings. Once established, lavender is highly drought tolerant. Never allow the soil to remain soggy — overwatering is the primary cause of lavender death, leading to root rot.

☀ïļ Lighting

Lavender requires full sun — a minimum of 6 to 8 hours of direct sunlight per day. Insufficient light reduces flowering and increases susceptibility to fungal diseases. Indoors, place the plant within one foot of a south-facing window.

ðŸŠī Ideal Soil

Plant in sandy, gravelly, or well-drained soil with low organic content. Avoid clay-rich or moisture-retentive soils. The ideal pH range is 6.5–7.5 (neutral to slightly alkaline). Amend heavy soil with coarse sand or perlite to improve drainage.
