Pruning Medlar
When and how — Mespilus germanica
Prune your medlar in December and January — the optimal month is usually January.
The next pruning window is December.
When to prune?
The fruit medlar is pruned in December and January.
Pruning fruit is about balancing growth and yield.
Fruit trees and bush fruits live in an eternal balance between leaf production (vigour) and fruit (yield). Prune too little and you get a dense plant with masses of small, disease-prone fruit. Prune too much and the plant reacts with watershoots and almost no fruit. The right line: once a year in winter dormancy (January–February) shape an open crown so light and air can reach every branch. With apple and pear, learn the difference between fruit spurs (short, 2–3-year-old wood — that's where the flowers come from) and wood buds (long whippy growth). Bush fruits need a different approach: redcurrant and gooseberry are pruned to an open goblet shape; blackcurrant needs renewal pruning where you remove one-third of the oldest stems at ground level each year.
How to prune medlar
Medlar requires very little pruning once established, which is one reason it suits low-maintenance gardens. Prune only in December or January, during full dormancy, to minimise sap bleeding and reduce the risk of disease entering wounds. Use clean, sharp secateurs for small branches and a pruning saw for anything thicker than your thumb. In the first few years after planting, focus on building a balanced, open framework. Remove any crossing, rubbing or inward-growing branches to create a clear centre that allows light and air to reach the interior. Aim for a goblet or vase shape with four to six well-spaced main branches radiating outwards. Cut back to an outward-facing bud to encourage the tree to spread rather than grow upright and congested. Once the tree matures, pruning is minimal. Remove dead, damaged or diseased wood whenever you spot it. Take out any suckers arising from the rootstock below the graft union. Thin overcrowded branches if the canopy becomes too dense, but avoid heavy cutting: medlar fruits on short spurs on older wood, and over-pruning reduces cropping. If a branch has become unproductive or awkwardly placed, remove it entirely at the base rather than shortening it. Medlar naturally develops an attractive, spreading habit, so resist the urge to shape it heavily. Light, thoughtful pruning every few years is all that's needed to keep the tree healthy and productive without compromising its graceful form.
Common mistakes
✗ Finally pruning after five years of neglect
A drastic prune after years of nothing triggers an explosion of watershoots and almost no fruit the next year. Better to gradually restore over 2–3 years than do everything in one winter.
✗ Pruning blackcurrant the way you prune redcurrant
Blackcurrant fruits on one-year-old wood, redcurrant on short, multi-year spurs. Prune a blackcurrant for shape (like redcurrant) and you'll harvest nothing.
✗ Pruning during frost
Wounds don't heal in frost and the wood can split. Wait for a frost-free day, even in winter dormancy.
Hold off on pruning
Better to wait than prune at the wrong moment. The next optimal window is December. Until then: leave the plant alone — only remove dead or diseased wood (which you can do year-round).
