The trunk is taken out for 2-3 years, and when it reaches a height of 1.5-2 m, the growth point is pinched to stimulate branching.

In order to accelerate the germination of viburnum seeds, they need to be subjected to pre-sowing treatment. Freshly harvested seeds are stacked with nylon stockings with wet sawdust and stored at room temperature for two months, and when they begin to germinate, they are placed in the bottom drawer of the refrigerator for a month, after which they are sown to a depth of 3-4 cm in boxes and wait for germination.

When in the spring the shoots from these buds grow by 8-10 cm, Air purifying plants in Karachi, are spudded again to a height of 4-5 cm. When the shoots stretch to 20-30 cm, they are dug up, pulled at the base with copper wire, and again spudded to a third of the height. After a couple of weeks, another hilling is carried out. By autumn, the shoots are dug up, separated and transplanted to a permanent place.
