π± How to Care for Plane Tree to Prevent Anthracnose?
π§ How to Water
Water frequently during the first 2-3 years of growth until the root system is established. Mature trees tolerate drought but benefit from watering during prolonged dry spells. Avoid waterlogging the soilβprefer well-drained soils.
βοΈ Lighting
Plane trees require full sun (at least 6 hours of direct sunlight daily) to grow vigorously. In shaded locations, growth slows down, and the tree becomes more susceptible to fungal diseases.
πͺ΄ Ideal Soil
Adapts to clay, loamy, and sandy soils. Prefers fertile, deep, and well-drained soils with a pH between 5.5 and 8.0. Tolerates compacted and slightly alkaline soils, making it ideal for urban environments.
