One of many primary gardening chores {that a} backyard or allotment proprietor should carry out infrequently is pruning timber and shrubs. Most species of timber and shrubs require common pruning for good development, flowering, or fruiting. Every plant species requires an acceptable time of pruning (see tree and shrub pruning calendar). The climate can also be vital – if pruning is finished in spring or autumn, select a dry, sunny, and heat day, and in summer time don’t perform such procedures throughout scorching climate.
We additionally suggest studying the attention-grabbing article snow broom for deck.
Instruments mandatory for tree and shrub pruning operations:
The essential instrument is a secateurs – atypical or with prolonged arms. As well as, the tools ought to embody saws and numerous kinds of knives. Instruments used for chopping ought to be well-sharpened, cleaned, and disinfected. Denatured alcohol can be utilized for disinfection. Bigger chopping wounds ought to be handled with a wound lubricant (Funaben 3, Santar SM, Tervanol, Lac Balsam, or emulsion paint with a 2% addition of Funaben 4, Fundazol, Topsin, or Copper 50). These brokers facilitate the therapeutic of wounds ensuing from excision and include bactericidal and fungicidal elements.
How pruning ought to be carried out:
Skinny branches are all the time pruned above the bud – the outer one if the department grows vertically (the bud is to be directed from the trunk outward to ensure that the plant to develop outward) or above the highest bud if we’re coping with a department rising horizontally. A pruning shear is used as a instrument. Thicker branches are reduce with a noticed. Place of chopping – proper on the thickening on the root (for the so-called ring) or leaving just a few centimeter items (for the so-called pivot or stump). Stump chopping is advisable for cherry, candy cherry, plum, or apple timber. Reduce wounds ought to be leveled and cleaned with a pointy knife after which protected with an acceptable agent.
Strategies of pruning:
Pruning of cuttings – is carried out when it is advisable to plant a plant with naked roots. The roots ought to be reduce easily and the aboveground half ought to be pruned in order that the stability between the roots and shoots of the plant is maintained.
Formative pruning – is carried out on younger fruit timber. Its goal is to create a robust trunk and a well-lit, robust crown, able to supporting the load of the fruit. Such pruning is carried out in early spring.
Clear-cutting pruning – removes diseased, dry, and damaged shoots or these rising to the middle of the bush.
Rejuvenation pruning – is used for older vegetation and is meant to enhance the looks of the plant and stimulate flowering. Among the outdated shoots are reduce out and a brand new plant behavior is created from probably the most prolific younger shoots. It’s typically price entrusting an skilled gardener to carry out this process.
Pruning of cold-green shrubs:
In relation to pruning, this can be a group of vegetation which might be pruned often (besides yew). Most coniferous shrubs require (and tolerate) solely minor therapies of this kind. Primarily, withered, damaged, diseased, or frosted branches are pruned. Extra pruning is finished solely to these vegetation to which we deliberately wish to give some form. Evergreen deciduous shrubs want pruning solely in case of significant harm. Rhododendron shrubs might be rejuvenated by pruning single shoots (in early April).
Reducing decorative shrubs that shed their leaves:
That is already a barely tougher artwork, however it’s price chopping shrubs as a result of pruned vegetation bloom extra abundantly and have a greater behavior. Decorative shrubs shedding leaves are divided into two teams:
Early flowering shrubs – resembling forsythia, quince, cherry, or snapdragon type flower buds in autumn, so they’re pruned after they end flowering, in spring, shortening the lengthy shoots from 1/2 to 1/4 of their size. Pruning these shrubs earlier than flowering might outcome within the plant not blooming in any respect! Alternatively, you may skinny the shrub.
Willow iva – to keep up a pleasant plant behavior, it ought to be pruned recurrently. Carry out pruning instantly after flowering (late April, early Could), shortening the shoots to 1/4 size. If you’re pruning the grafted type then shorten the shoots to 1/3 of their size.
Forsythia requires annual pruning after flowering (Could). Reduce off 2/3 of the size of flowering shoots. If not pruned, forsythia shaves off the underside and blooms much less properly.
Shrubs and timber of almond ought to be pruned fairly not often – each 3-4 years and never too onerous as a result of the flowers bloom alongside all the size of the shoot.
In grafted vegetation, you additionally have to rigorously reduce the shoots rising from the rootstock (normally straight and skinny), which disfigure and weaken the plant.
Pruning of lilac (un) shrubs ought to be carried out instantly after flowering; the set seeds weaken and disfigure the plant. Root suckers of lilac ought to be systematically reduce to not weaken the plant.
Present blood currants require pruning – cut-out shoots 4 years outdated and older. Pruning ought to be completed in early spring, the place of chopping low to the bottom.
Tamarisks are pruned after flowering (June). Each few years a robust rejuvenation pruning is advisable – the plant will bloom extra abundantly and have a greater behavior. Frozen tamarisk shrubs ought to be pruned close to the bottom in March; they are going to sprout new shoots after this process.
Surprise bush doesn’t require common pruning, however it’s good to trim the bush just a little each 2-3 years. Pruning is carried out after flowering.
Shrubs that bloom in summer time and autumn – resembling hydrangea, pentacle, or buddleia – bloom throughout this 12 months’s development. They’re pruned in early spring when the chance of onerous frosts has handed.
Reducing roses – admittedly, roses are additionally shrubs, however their chopping requires a separate dialogue. Reducing roses is a barely extra sophisticated process than for different shrubs, primarily as a result of several types of roses are reduce otherwise. In early spring, broken and disease-infested shoots are reduce after mounding. Primary pruning is carried out in April within the interval after the final frost however earlier than the formation of recent shoots. Common pruning is required for large-flowered roses – their flowering will depend on it. The process ought to be carried out yearly, instantly after uncovering the bushes. Take away weak or broken shoots by chopping them with secateurs on the base. The remaining shoots are shortened by barely lower than half. Observe the rule that the stronger the shrub grows, the much less we reduce the shoots. On stronger-growing shrubs, we reduce from 6 to meshes, and on weaker-growing shrubs from 2 to 4 meshes. The place of chopping ought to be not more than half a cm above the mesh dealing with exterior the crown. Reduce barely diagonally. Reducing impacts the scale and variety of flowers and the time of flowering. Roses with severely shortened stems bloom later however their flowers are bigger and set on robust, lengthy stems. Flowers of much less shortened rose bushes will bloom earlier. The bushes could have extra flowers however they are going to be finer and the stems will likely be weaker and shorter.
When chopping multiflora roses (bedding roses) on every shoot depart the identical variety of eyes, that’s, from 2 to six. Weak shoots don’t reduce.
Reducing bush roses is just not mandatory, however infrequently you may reduce too dense or outdated shoots close to the bottom and form the bush a bit. The identical is finished with climbing roses, park roses, and wild roses.
Cowl roses don’t require common pruning – solely outdated and feral shoots are eliminated. In late autumn, solely diseased shoots are pruned and the longest branches are barely undercut.
American milin – frosted and dry shoots are eliminated. It is usually essential to shorten final 12 months’s shoots, on which there have been flowers. These procedures ought to be carried out in early spring. Reducing the plant causes extra plentiful flowering.

Stone species, resembling cherries, are reduce in August after the harvest. Peaches bear fruit on two-year-old shoots, and due to this fact all branches from which the fruit has been harvested ought to be reduce in half.
Pruning of fruit timber after planting
All newly planted fruit timber ought to be pruned. This is applicable to timber planted in each spring and autumn. The tops of the youngest shoots typically fail to lignify and freeze throughout the winter. Throughout spring pruning, examine if the wooden is just not browned. Whether it is, reduce the shoot all the way in which to wholesome, brilliant tissue. If the tree has a number of lateral shoots, you then solely have to shorten them barely. We reduce the information about 20-30 cm above the best branching.
