Betula grow throughout the world, and are known for their bark which, on all species except the gray birch, peels off in strips. These trees produce large amounts of pollen; they're thought to be responsible for up to 20% of hay fever cases in the northern hemisphere. Bark from betula has been used for centuries to create paper. Afghani texts from the first century were made using this type of bark, and the ancient Romans also wrote on birch paper. The trees' sap and syrup are traditional delicacies in some countries.
Water:
Originating from temperate regions, betula prefers moist, well-drained soil, requiring watering every 1-2 weeks to maintain consistent moisture without waterlogging. As a moderately drought-tolerant, deciduous species, betula sheds leaves seasonally, influencing its water uptake and conservation strategies.
Propagation:
Betula is primarily propagated through seeds, cuttings, and layering. Successful germination requires stratification for winter simulation. Use young wood for cuttings, maintain consistent moisture in well-drained soil, and provide partial to full sunlight. The propagation process can be moderately challenging, especially without cold winters.
