The landing hole is made 50 cm deep. Half of it is covered with drainage elements - crushed stone, broken brick. A layer of compost or humus, a shovel of ash and 50 g of superphosphate is placed on top. A support for a garter is installed inside the hole. The stalk is pre-soaked in water to enhance root formation, then the hole is buried almost to drainage, it is closed, and a mound of earth about 20 cm high is formed on top.
