🌱 How to Care for Scarlet Firethorn to Prevent Spider Mites?

💧 How to Water

Water deeply but infrequently — Pyracantha coccinea is highly drought-tolerant once established and prefers soil that dries out between waterings. Overwatering is the primary cause of root rot. During prolonged dry spells, water every 10–14 days. Avoid wetting foliage to reduce fungal disease risk.

☀️ Lighting

Plant in full sun (6+ hours of direct sunlight daily) for the best flowering and fruiting. Partial shade is tolerated but results in fewer flowers and berries, and increases disease susceptibility.

🪴 Ideal Soil

Tolerates a wide range of soils including clay, loam, chalk, and sand, provided drainage is good. Prefers slightly acidic to neutral pH (5.5–8.0). Avoid waterlogged conditions. Avoid overly rich soils — excess fertility promotes leafy growth at the expense of berries.
