The cutting of certain ornamental shrubs is carried out at different times, depending on the properties of the species and the desired effect. Coniferous bushes are cut only occasionally, since most species do not have the ability to reproduce truncated tops and truncated shoots from dormant buds, the lower ones. For pruning in this group of plants, they only correct the structure or habit. They are usually carried out at the end of the dormant period or after growth has ended. Yew trees are an exception among conifers, which can stand the cut perfectly, even deep, and have an exceptionally high ability to grow back from dormant buds, exposed and stimulated by light.
Evergreen deciduous shrubs are cut like conifers - at the end of the dormant period or after the end of growth.
Deciduous shrubs, the main decorative value of which are flowers, cuts at different times.
Blooming from buds formed during the previous growing season (Forsythia, Prunus triloba, Spiraea, Tamarix sp.) usually shines out after flowering, removing the oldest branches from overly thickened bushes. Loosening shrubs can be done by skillfully cutting flowering twigs or with flower buds, like nip. forsythia.
Flowering shrubs, ornamental fruit (Chaenomeles, Pyracantha) cut after fruit set, removing shoots without fruit from excessively thickened places. An intensive spring pruning usually causes numerous shoots to grow, which do not produce flower buds.
Shrubs blooming at the ends of this year's shoots (Buddleya, Call it, Philadelphus, Rosa, Spiraea bumalda, Spiraea japonica) it is usually cut during the dormant period. Intensive pruning of older shoots causes stronger regrowth of new ones and more magnificent flowering.
Shrubs of multiflorous roses (polyants) and large-flowered plants are usually cut in the spring after their discovery. Cutting the shoots to half their length in autumn makes it much easier to cover for the winter. In this case, a final spring cut is also necessary. Shrubs blooming on perennial twigs (Barberry, Cotoneaster, Crataegus) cut during the dormant period to remove older shoots, excessively thickening.
