When to prune viburnum
Like other garden trees and shrubs, it is better to cut the viburnum in the spring, before the start of sap flow. You can cut it in the fall, at the end of the leaf fall, but since it is difficult to know for sure when the frosts will strike, it is better to carry out serious pruning (rejuvenating or shaping) in the spring, and in the fall it is worth cutting the viburnum only for sanitary purposes.
Pruning viburnum in the spring
In nature, viburnum grows like a tree or in the form of a bush, and so it is formed - a bush or a tree. In the spring, before the start of sap flow, they carry out sanitary and then formative pruning of the viburnum: if you want the viburnum to grow as a tree, leave one vertical branch, and cut the rest into a ring, and remove the buds in the lower part of the stem where the bole is planned. 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. All this time you will have to remove the root shoots, otherwise, you will have a bush. Keep the bole clean by removing the resulting side shoots.
Whether you form a tree or let the viburnum grow as a bush, Plants suitable for Karachi, you need to cut the plant in any case, because with age, its crown will thicken and grow, and it will be more and more difficult for you to remove berries from it, and the quality of the fruits will begin to deteriorate over time, and the number will decrease.

The next year, replace another third of the old branches, and in the third year, replace the last third. Rejuvenating pruning of viburnum, shaped like a tree, is carried out according to the same scheme as similar pruning of fruit trees.

How to propagate viburnum
Viburnum is propagated by seeds and vegetatively - cuttings, avocado Plant, horizontal and vertical layering, and basal processes. Seed propagation is hampered by the fact that the seeds germinate within two years. The simplest and least time-consuming method of propagating viburnum with vertical layering.
Propagation of viburnum seeds
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. In the spring, after the return frosts have passed, the seedlings are planted in open ground, watered abundantly, and shaded from direct sunlight for the first time.
Propagation of viburnum by vertical layering
In autumn, the lower branches of young plants are shortened on the viburnum, leaving only 2-4 buds on them, and the stem is highly spudded. 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.
