The bark of the tree is smooth and gray when young, but becomes rough and dark brown as it ages. The tree produces cones that are green when young, but turn brown and woody as they mature. The cones can remain on the tree for several years.

The tree should be watered deeply once a week during the growing season, and less frequently during the winter months. Fertilizer should be applied in early spring, using a slow-release fertilizer specifically formulated for conifers. The tree is hardy in zones 6 to 9.
Common Pests & Diseases
The Pinus Monophylla is generally resistant to pests and diseases. However, it can be susceptible to pine needle scale, which can cause yellowing and browning of the needles.

To prevent pest infestations, the tree should be regularly inspected and any affected branches or needles should be pruned and removed. Fungal diseases can also be a problem, especially in wet conditions. To prevent fungal infections, the tree should be planted in well-drained soil and any dead or diseased branches should be removed.
