How often do you water a baby pine tree in a pot?

Pine trees planted in the landscape will need to be watered for the first year after planting. Watch the weather and when you have not had rain in four or five days, give your pines a long deep drink of water.

In the next couple of years, watch the weather and again, when the weather is inordinately dry water your trees. A slow deep soaking is better than dumping a quick bucket on them.

After five years, the only time you need to water is if you experience a drought.
