Pruning Fruit Trees in Late Winter: Apple, Pear, Peach

When: after the cold, before the buds

Utah State gives both ends of the window for apples. Prune after the coldest part of winter, because pruning temporarily lowers the cold hardiness of the tissue around the cuts and early pruning puts the tree at risk of low-temperature injury. Prune before the buds swell, because after that the work knocks off blossoms and buds. UF/IFAS says the same for Florida: pruning stimulates tender new growth that a freeze damages, so prune late enough in winter that extreme cold has likely passed.

Iowa State calls late February to early April the best time to prune fruit trees in Iowa, finished before they break bud. University of Minnesota Extension prunes apples every year in March and avoids wet spells. Clemson does the major pruning of apples and pears in the dormant season, before active growth begins in spring.

The order: apples and pears, cherries, then peaches

University of Illinois Extension prunes apples and pears in late February and early March in central Illinois, cherries after them in mid-March before the buds begin to swell, and peaches last, as their buds start to swell and turn pink.

Clemson holds peaches back for a reason. It says not to prune peaches from October to January, and in the South Carolina mountains and Piedmont to wait until mid-February: pruning in late winter reduces the chance of winter injury and of infection by bacterial canker. Its young peaches are pruned in mid-February to early March.

How much to take

A quarter at most. Illinois says never prune more than 25% of a fruit tree’s wood in a single dormant season — its “pruning budget”. Going over sends the tree into survival mode, and it grows many water sprouts that then have to come out next season. Utah State explains why: dormant pruning leaves the roots with more reserves than the smaller canopy needs, so the tree pushes more new growth.

Less on young trees. Illinois says young trees with evenly developing scaffold branches need no pruning in their first two years, trees three to five years old only minor pruning, and trees over five moderate pruning. Clemson spends an apple’s first three years on training only and lets it carry a light crop in the fourth or fifth.

Heavy pruning, less fertilizer. Clemson says a heavily pruned tree may not need fertilizer for a year or two, and that a tree severely pruned in winter should not be fertilized that spring.

The cuts, in order

1. Dead, diseased and damaged wood. Illinois starts every tree this way, because dead and damaged wood can harbor insects and disease. Utah State cuts fire blight out 8 to 12 inches below the lowest sign of infection, and dips the tools in a 10% bleach solution (1 part bleach to 9 parts water) between cuts.
2. Water sprouts and suckers. UF/IFAS removes both completely: water sprouts grow along branches, often at pruning cuts, and suckers grow from the trunk or roots.
3. Crossing and inward branches. Where two branches cross, Illinois removes one; crossing branches shade each other, and dense canopies breed disease in long wet springs. Sunlight should reach every major branch.
4. Thinning cuts over heading cuts. A thinning cut removes a branch back to where it starts; a heading cut shortens it. Utah State says heading cuts stimulate vigorous growth just below the cut, so it shortens an overlapping branch with a thinning cut back to the scaffold. UF/IFAS says not to make heading cuts on wood over a year old.
5. Height last. Clemson controls a bearing tree’s height by cutting the top back to weaker side branches.

Apples and pears: a central leader

UF/IFAS, Clemson and Illinois train apples and pears to a central leader: one main trunk up the middle with several wide-angled limbs spaced around it, maturing to a pyramid. Utah State wants a cone, narrow at the top, so the top does not shade the bottom.

• Starting a whip. Clemson heads an unbranched one-year-old tree to 28 to 32 inches for a standard tree and 30 to 35 inches for spur-type and semi-dwarf ones; Utah State makes the cut at 30 to 36 inches.
• Choosing scaffolds. Clemson spaces scaffold branches at least 6 inches apart up the trunk and evenly around it, and removes branches that form angles of less than 45 degrees with the trunk. Utah State spreads them to about 60 degrees from the leader, just after bud break when the wood is most flexible, and never below horizontal.
• Pears. Clemson says pears naturally grow narrow, upright branches, so it weights them, ties them to pegs or braces them apart with spacer sticks.
• A neglected tree. Clemson opens the interior first, removing the upright, vigorous shoots that shade it, then keeps three to five well-angled lower scaffolds, and spreads the work over two or three seasons. UGA Extension also spreads the corrective pruning of a neglected apple over two or three seasons.

Summer pruning has its place too. Clemson removes water sprouts, root suckers and fire-blight-infected wood in early summer or after harvest, late August to early September; UGA Extension prunes in early June and early August as well as in winter. Utah State waits for hot, dry weather to summer-prune where fire blight has been a problem. For apple varieties, pollination and rootstocks, see the apple tree zones page.

Peaches: an open center

Clemson, UF/IFAS and Illinois train peaches to an open center, shaped like a vase, with no trunk up the middle. Clemson’s steps:

• At planting, cut the tree back to about 30 inches, just above a side branch or bud, and keep three or four wide-angled branches spread evenly up and around the trunk, the lowest about 15 inches and the highest about 30 inches from the ground.
• Each late winter, remove low-hanging, broken and diseased limbs, then the vigorous upright shoots growing inside the scaffolds, to keep the center open.
• Keep good fruiting wood. Peaches fruit on wood that grew the previous season. Clemson keeps shoots about the thickness of a pencil and 12 to 18 inches long, cuts a third off any over 24 inches, and removes shoots thinner than a pencil and branches that hang down in the shade.
• Keep it low. Clemson prefers a tree 8 to 9 feet tall, lowered by cutting the scaffolds back to an outward-growing shoot.
• In early or mid-July, it removes the very vigorous shoots growing inside the tree, and leaves the small ones.

Clemson warns never to prune a bearing peach so hard that thinning the fruit becomes unnecessary: it cuts the crop and the size of the tree.

Thinning the fruit

Pruning is half the job. Clemson says apple and pear trees set more fruit than they can carry, and that failing to thin it cuts next year’s flower buds and can leave the tree bearing only every other year. It thins by hand to one fruit per cluster, clusters about 6 inches apart, within the four to six weeks after full bloom when next year’s buds form. For peaches it thins about four weeks after full bloom, spacing the fruit about 6 inches apart.

Grapes, blueberries and cane fruit

Iowa State says early spring is also the best time to prune most small fruits with woody stems, such as grapes, raspberries, blueberries, gooseberries and currants. Each has its own method, on its own page: grapes, which lose most of last year’s growth every winter; blueberries; and raspberries and blackberries, where the canes decide.

Common mistakes

• Pruning before the coldest weather is over. The tissue around the cut loses cold hardiness for a time (Utah State).
• Pruning peaches in early winter. Clemson says never October to January.
• Pruning after the buds swell. It knocks off blossoms (Utah State).
• Taking more than a quarter. The tree answers with water sprouts (Illinois).
• Heading back old wood. UF/IFAS says it brings water sprouts and suckers and can disfigure the tree.
• Over-pruning a young tree. It delays fruit (Utah State).
• Skipping fruit thinning. Clemson says the tree may then bear only every other year.
