Plant a river birch tree in spring or fall when the soil is moist and the temperatures are cool. This is a fast-growing tree that averages about 36 inches of growth per year. Dwarf varieties may grow a bit slower, taking 10 years or so to reach 10 feet. River birches are not particularly long-lived trees, however.

When should I plant a river birch tree?

The best time to plant birch trees is in the spring or fall, when the soil is moist and temperatures are cool. If planting in the fall, allow at least four to six weeks before the ground freezes to give the roots enough time to become established (see What to Plant in Your Fall Garden).

When should river birch trees be pruned?

The best times to prune river birch are during late spring, late fall and winter. Pruning in the spring before the first leaves emerge will cause the tree to lose sap, and fresh pruning cuts can attract birch borers in the summer.
