The soil for planting birch is loosened at a depth of 3 centimeters while harvesting weeds. Circles are mulched near the trunk with peat or peat compost, and sprinkled with wood shavings, the thickness of which is about 15 cm. Dry branches are pruned in spring.

One of the birch pests are pipe beetles. They damage young leaves and shoots. And a large colony can quickly destroy a tree. If the plant is affected by this beetle, then it is better to burn the leaves, and dig up the near-stem circles.

Pests such as the nun silkworm and the Corydalis bucephalus gnaw at the leaves of the Daurian birch down to the veins. It is advisable to shake off the caterpillars, and treat the tree with insecticides. If the May beetle larva has damaged the roots of a birch, then you need to dig up the trunk circle and check the ground for parasites.

Young DaurianBirch


Dahurian birch is propagated by sowing seeds, which are collected during the maturation of earrings. Almost universal germination drops rapidly, so it is better to sow immediately or in late autumn. Dried seeds are stored in an airtight container until a suitable seedling period. With such storage, 100% germination is maintained for two years.

Distinguishes Daurian birch speed and good survival, shoots grow into strong specimens. If the seeds are freshly harvested, then they are sensitive to light: in a dark room they germinate at a temperature of +15 … +32 ° C. At a temperature of 15 ° and below, sprouts are produced only with proper lighting. Before sowing, the seeds must be stratified at a temperature of 1 to 10 ° for 2-3 months. You can also treat them with gibberellic acid at a concentration of 100 mg / l during the day. This will protect the seeds from diseases and pests.
