🌱 How to Care for Arbequina Olive to Prevent Anthracnose?

💧 How to Water

Water deeply once or twice a week during the first year to strengthen the roots; after that, space out the waterings and allow the soil to dry out thoroughly between them, as excess moisture promotes root rot.

Prefer sandy or loamy soil with excellent drainage and a pH between 5.5 and 8.5. Avoid waterlogged or dense clay soils, which favor root diseases.
