Care Guide
Shore Pine prefers moist, well-draining soil and a sunny location. It can tolerate some shade, but too much shade can result in a thinning of the crown. The tree is hardy in USDA zones 6-9. It requires moderate watering and fertilization during the growing season. It is important to avoid over-fertilization, as it can damage the tree.

Pine Weevils can cause significant damage to the tree by feeding on the bark and branches. Pine Needle Rust is a fungal disease that causes yellowing and premature dropping of needles.
