🌱 How to Care for Japanese Camellia to Prevent Mealybugs?

💧 How to Water

Water every 7 days, or when the top 2 inches of soil feel dry. Rainwater or soft water is preferred in hard-water areas. Avoid waterlogged conditions — overly wet roots invite Phytophthora root rot.

Plant in dappled or partial shade; morning sun with afternoon shade is ideal. Avoid harsh midday sun, which can scorch flowers and foliage. Sheltered spots with indirect light from structures or taller plants work well.

Use acidic, organically rich, well-drained soil with pH 5.5–6.5. Ericaceous (acid) compost is ideal. A mix of garden soil, peat-free ericaceous compost, and perlite improves drainage. Never plant in chalky or waterlogged ground.
