6 Step Pear Tree Summer Pruning Routine with Felco 7 Secateurs on Conference

Conference is a tip-and-spur bearer, which is why summer pruning rewards it more than most varieties. Cut back the long whippy growth in late summer and you redirect sap into the fruit buds clustered along the older wood, instead of feeding another metre of leaf-heavy extension shoot. The Modified Lorette System, set out by the Royal Horticultural Society for trained pears, puts the main window between mid July and the third week of August across most temperate climates. The exact start depends on your tree: wait until the bottom third of this year’s new shoots has turned woody and stiffened to a pale brown.

The Felco 7 earns its place here because of the rotating handle. A summer prune on a mature Conference can mean two hundred cuts in a session, and the swivelling lower grip takes the repetitive strain off the base of the thumb. The blade is the same hardened steel as the Felco 2, but the ergonomics change how long you can keep the cuts clean before fatigue starts dragging the wood.

Step one: strip the blade before you touch the tree

Sap residue from earlier jobs carries bacterial canker and brown rot spores. Pseudomonas syringae, the canker organism, moves on dirty steel as readily as on wind and rain. Before the first cut, wipe the Felco 7 blade with a cloth dampened in surgical spirit or a 70 percent isopropyl solution, working into the pivot where gum collects. If the blade has been sitting since spring, run it twice through the Felco 902 carbide sharpener at the factory angle, three light passes per side, until a fingernail catches on the edge without snagging.

A blunt blade crushes the shoot instead of severing it, and a crushed Conference stub dies back further than a clean cut, leaving a ragged entry point for infection. Test the closing action: the spring should snap the handles open the instant you release pressure. If it lags, the spring has clogged with dried sap and needs a drop of light machine oil at the pivot bolt.

Step two: read the shoot before deciding the length

Walk the tree first. On a mature Conference espalier or bush you are looking at three kinds of growth, and each gets a different treatment. The current season’s extension shoots, the long pale ones over about 20 centimetres, are your main targets. Side laterals growing directly off the main framework branches get cut back to three leaves above the basal cluster, counting from where the leaves bunch at the base of the shoot. Shoots growing off existing spurs, the older knobbly fruiting wood, get shortened to one leaf above their own basal cluster.

The basal cluster is the giveaway. At the bottom of each new shoot, three or four leaves sit close together before the spacing opens out up the stem. That tight rosette marks where the wood has firmed and where the fruit buds will form for next year. Cut above it and you preserve those buds. Cut below it into the clustered zone and you lose the fruiting potential for that spur entirely.

Step three: the lateral cut

For a lateral growing off the framework, count three full leaves above the basal cluster and cut just above the third. Angle the Felco 7 so the blade, not the anvil-style counter-blade, sits against the part you are keeping. The cut should sit roughly 5 millimetres above the bud, sloping away from it so water runs off rather than pooling on the bud itself. Pears are slower than apples to seal a wound, so a clean angled cut matters more here than on a vigorous plum.

Do not cut flush to the bud and do not leave a long snag. A stub longer than about a centimetre dies back and becomes a foothold for canker working its way down into the framework branch.

Step four: the spur sub-laterals

Shoots arising from established spur systems get the shorter treatment: one leaf above the basal cluster. This is the cut that builds fruiting wood over years. A Conference spur that has been summer pruned consistently will carry six to ten fruit buds within four or five seasons, where an unpruned equivalent throws another extension shoot and bears nothing useful.

Go slowly through the spur systems because they crowd over time. If a spur has become a congested fist of old wood with five or six competing sub-laterals, this is the moment to thin it. Keep the two or three best-placed sub-laterals, each pruned to one leaf above its cluster, and remove the rest entirely back to the spur base. An overcrowded spur shades its own fruit buds and produces small, poorly coloured pears.

The difference shows in the fruit. A well-spaced spur ripens Conference to its full elongated shape with the russet skin Conference is known for; a congested one gives you a cluster of stunted fruit competing for the same light and sap.

There is a temptation to rush this stage because it is finicky and the cuts are small. Resist it. The spurs are where next year’s crop lives, and a careless thinning here costs you fruit twelve months out, long after you have forgotten the afternoon you hurried.

Mature trees may have forty or fifty spur systems. Work along one framework branch at a time and finish it before moving on, so you do not lose track of which spurs you have already addressed.

Step five: secondary regrowth in early September

A hard summer prune sometimes triggers a flush of soft secondary shoots from the cut points within three or four weeks, especially on vigorous rootstocks like Quince A. In early September, go back over the tree and pinch or cut these secondary shoots back to one leaf. Leaving them lets the tree push sappy autumn growth that will not harden before the first frosts and dies back over winter.

Step six: clear the prunings and seal the routine

Gather every cut shoot off the ground. Conference prunings carry brown rot and scab spores that overwinter in leaf litter and reinfect the tree the following spring. Pear scab, caused by Venturia pirina, survives in fallen material and releases ascospores during wet spring weather precisely when the new leaves are most vulnerable.

Do not feed the cuttings to a slow compost heap near the tree. They want either a hot heap that reaches 60 degrees Celsius and breaks the spores down, or the council green bin. The healthy leaf material you strip during pruning is a separate question: clean pear leaves rot down into a decent leaf mould over a couple of years, but keep anything showing the olive-brown blotches of scab well away from that pile.

Wipe the Felco 7 down again at the end of the session, the same surgical spirit pass you started with, and store it closed. A blade put away dirty in August is a blade that spreads last year’s problems into next year’s wood.

How the timing changes by climate

The RHS window assumes a British or northern European summer. In a hotter, drier climate the wood firms earlier and the prune can move into late June or early July; in a cool maritime garden it can slip to the very end of August. The signal is the wood, not the calendar. Squeeze the base of an extension shoot between thumb and forefinger. If it bends like a green bean, it is too early and the cut will provoke regrowth. If it resists and the bark has gone matt and pale, the shoot is ready.

Prune too early and the tree answers every cut with two new soft shoots, and you spend September chasing regrowth you created. Prune too late, once the leaves yellow and start to drop, and you lose the redirection effect entirely because the sap has already withdrawn into the framework for winter. The narrow middle window is where the technique actually works.

One open question sits behind all six steps: how much vigour does your rootstock bring to the fight? A Conference on Quince C behaves nothing like the same variety on a seedling pear rootstock, and the pruning intensity that calms one will starve the other. Watch what the tree does in the three weeks after you cut, and let next summer’s routine answer for the rootstock you actually have.
