🌱 How to Care for Rocket Larkspur to Prevent Spider Mites?

💧 How to Water

Water once every 5–7 days when the top layer of soil (approx. 2–3 cm) dries out. Avoid waterlogging the soil — larkspur is sensitive to root rot. During long dry periods, shorten the interval to 3–4 days. Do not pour water directly onto the leaves or flowers.

☀️ Lighting

Place in a full sun location — at least 6 hours of direct sunlight per day. In warmer regions, slight afternoon shade is advisable to prevent the flowers from overheating. Lack of light causes the stems to become leggy and results in poor flowering.

🪴 Ideal Soil

It prefers fertile, deep, well-drained soil (sandy-loam) with a pH value of 6.5–7.5. Incorporate compost or well-rotted manure before planting. Lighten heavy clay soil with perlite or sand. Good drainage is key to preventing rot.
