Family Betulaceae (Birch family)
Birch trees are all deciduous. Their size varies
depending on species; B. pendula, for example grows between
30 and 40 feet.
Optimum conditions for growth
Betula spp. grow best in full sun with
regular fertilizer and frequent irrigation. Given adequate water,
they can grow in various climatic zones, depending on the species.
Birch are relatively short-lived trees, especially in areas with
hot, dry summers, where birches usually decline and die within
about 20 years after planting. Birches are brittle and can be
damaged by wind and ice.
