🌱 How to Care for Aleppo pine to Prevent Anthracnose?

💧 How to Water

Water regularly, approximately every 15 days, only during the first year after planting to encourage root establishment. After this period, the Aleppo pine manages on its own thanks to its high drought tolerance: avoid any additional watering, as excess water is more dangerous for it than a lack of it.

☀️ Lighting

Requires full sun exposure, with a minimum of 6 to 8 hours of direct light per day. It is one of the most light-demanding conifers: it tolerates neither shade nor prolonged partial shade, which weaken its growth.

🪴 Ideal Soil

Prefers light, sandy to stony soils, including limestone and nutrient-poor soils, provided they are perfectly draining. The pH can range from slightly acidic to frankly alkaline. The main risk is root asphyxiation in heavy or waterlogged soil, which promotes root rot.
