Water pines regularly after planting to help establish strong roots. Pines require about 1 inch of water each week from either rain or home irrigation. Continue regular maintenance watering for the first two years of the plant's life. Arrange a circular sweat or soaker hose around the base of the tree.

The tree often turns totally brown and dies rapidly in the fall, but it may not be noticed until spring. The most common cause of brown pine needles occurs in the fall and is normal. Pines shed older needles similarly to other trees' fall foliage drop. The needle drop may be impressive in a large healthy tree.

Pine trees go about their essential work converting energy from the sun into the fuel they need to grow and survive – photosynthesis, in other words – via green leaves of a distinctive form shared by many other conifers: needles.
