What are the winter pear tree pruning techniques? How are pear trees pruned in winter? Experienced gardeners are invited to share their advice.Winter pruning of pear trees is carried out after the leaves fall and before bud break. Its main purposes are to develop the tree shape, adjust the canopy structure, develop fruiting branch groups, adjust the number of flower buds, regulate the quality and quantity of branches, promote ventilation and light penetration, renew and rejuvenate the canopy, delay senescence, achieve a balance between growth and fruiting and stable high yields, and lay a good foundation for a bountiful harvest.
Zhongdiwang has organized the winter pruning techniques for pear trees according to tree age. The details are listed below for gardeners' reference.
Pruning methods for young pear trees:
The main purpose of pruning young pear trees is to shape them well, develop a good framework, encourage branching, and expand the canopy and promote branching for early fruiting.
For young pear trees, long branches can be lightly pruned and left unpruned, upright vigorous branches can be bent flat, and medium and short branches can be retained. The shoots that emerge should be used as much as possible to expand the canopy. Apart from thinning out some overly dense branches, pruning is generally not carried out.
On the main branches and secondary main branches of young pear trees, all overly dense branches, thin and weak branches, diseased and pest-infested branches, and branches that disrupt the tree shape should be cut off entirely. Long branches should be headed back to develop them into fruiting branch groups; medium and short branches should have their tips cut if vigorous, or be left unpruned if weak; branches with narrow angles should be spread, pulled, or weighted down by other methods to widen the branching angle, reduce apical dominance, and promote early flower bud formation.
Pruning methods for pear trees in full fruit period:
The main purpose of pruning pear trees in the full fruit period is to control tree growth, keep the tree within a predetermined range, and keep the canopy from becoming shaded, so as to facilitate ventilation and light penetration, maintain a vigorous and stable moderate tree vigor, and extend the full fruit period.
For pear trees with relatively vigorous growth, vigorous growth should be controlled, with more thinning out and less heading back, removing upright branches and keeping slanting branches, and retaining more flower buds so that the fruit load suppresses tree vigor and moves it toward moderate vigor; for trees with relatively weak vigor, heavier pruning should be used, heading back strong branches and thinning out weak branches; for some medium and short fruiting branches, heading back should be used, removing some flower buds and converting fruiting branches into vegetative branches to increase the proportion of vegetative branches.
For pear trees with stable vigor, the focus is on pruning the fruiting branch groups; for pear trees with a large number of flowers, inferior flower buds should be cut off, axillary flower branches should be headed back, and the ratio of fruiting branches to vegetative branches should be adjusted.
Pruning methods for pear trees in the senescent period:
Pruning of varying intensity should be carried out according to the degree of senescence of the pear tree. The purpose of pruning at this stage is to restore tree vigor, rejuvenate branch groups, and extend the fruiting years. Drooping perennial branches should be shortened back, and the point of shortening should be chosen at a good upward-facing branch; the leader branch should be a vigorous branch with vigorous buds so that it grows upward, and some flower buds should be cut off and weak branches thinned out.
Water sprouts should be used as much as possible to fill in the broken canopy, restore tree vigor, and regain high yields. For severely senescent pear trees, the canopy should be sawed off, leaving only the framework of the main and lateral branches, to promote the sprouting of latent buds, rebuild the canopy, and restore yield. When renovating senescent trees, fertilizer and water management and pest and disease control must be strengthened.
