Why Do We Prune in Winter?
Pruning in winter when the tree is dormant allows for clear visibility without foliage in the way. It avoids exposing fresh wounds to disease and insects during the spring and summer growing seasons. Winter pruning also balances the top growth and root system, as roots continue growing underground. Finally, removing excess branches opens the canopy to sunlight and air circulation. Pruning apple & pear trees in particular is essential for disease prevention and sunlight exposure.
The Best Time in Winter to Prune
The optimal window for winter pruning is between late autumn after leaf drop and before early spring when buds begin to swell. Avoid pruning during hard frosts. Ideally, you should prune on a dry, calm day to give clean cuts and prevent wind damage. Late January to February is generally the best time but pay attention to your climate and tree varieties. Apple and pear trees are best pruned in late January/early February depending on your regional climate.
Winter Pruning: The Process
Making a Plan: Before lopping off branches, envision your goals. Consider tree size, planting location, desired harvest and aesthetics. Examine the structure and health. Look to eliminate diseased, damaged, congested, and crossing branches first. Judge the remaining branch angles and positions. Finally, aim to evenly distribute an open network throughout. Pay special attention to the centre clearance and airflow for fungus and disease-prone trees.
Removing wood: Start by cutting out all dead, diseased, and damaged branches. Saw off broken limbs completely. Also, remove branches that are rubbing together causing wounds or bark damage. Your cuts should be clean just outside the branch collar without leaving stubs.
Canopy Guidance: Generally, you should remove no more than 30 per cent of the total canopy per year. This prevents shock. First, remove inward-growing branches that are shading the centre. Cut overlapping branches to outward-facing buds or branches. Remove suckers sprouting from the base or roots. Apple and pear trees should follow the 30 per cent canopy removal rule to prevent stress on the tree.
Dehorning is the process of cutting back major scaffold branches over several years to rejuvenate ageing fruit trees. Spread dehorning cuts over 2-3 years for apple and pear trees to gradually renew productivity.
Repurposing Your Tree Prunings
The trimmings from properly timed winter pruning are full of excellent wood chips for garden mulching and biomass for the compost pile. Smaller pieces provide kindling for fireplaces and woodstoves. Shredded prunings can be used as pathway material or as a nutritious additive to livestock bedding.
Applying a diligent winter pruning regimen keeps fruit trees healthy, established, and productive for years to come. Follow the basic guidelines of timing, technique, and objectives provided here as a framework to develop an annual system adapted to your specific trees and climate. With pruners in hand and a watchful eye, your orchard will thrive.
