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.
Typically trees will need to be watered every one to two weeks in the summer, and every three to four weeks in the winter. You need to check your individual soil for moisture content before determining your personal water schedule. If the top few inches have thoroughly dried out, then its time to water again.
