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.
If you have more trees to water than you can get to in the two hour weekly period try putting them on a rotation so they get a good watering every 2 to 3 weeks or even 4 if you have that many trees. It would be better to do a good, deep watering once every few weeks than to apply a little water to each tree.
