When to prune peach trees
Late winter, as late as practical, from about mid-February to early March in the Southeast, close to bloom. Peach trees (Prunus persica) flower on old wood, which sets the timing. Type your town for the dates at your weather station.

How to prune peach trees
- Peaches fruit only on shoots that grew the previous summer, so each year's pruning must leave plenty of last year's moderate-length shoots.
- Train to an open center (vase shape) with 3 or 4 wide-angled main limbs spaced around the trunk.
- Peaches respond to fairly heavy annual pruning; an Oregon State guide notes up to about half of last season's growth is commonly removed.
- In June or July, removing strong upright shoots that shade the middle helps next year's flower buds form.
- At planting, cut the young tree back to about 24 to 30 inches tall to force low side branches for the scaffold limbs.
- Keep the lowest scaffold limb roughly 15 to 20 inches above the ground and remove branches below that.
- Hold mature trees to about 7 to 9 feet tall so you can prune, thin and pick from the ground or a short ladder.
- The best fruiting shoots are about pencil thickness and roughly 12 to 18 inches long; very short, thin shoots give small fruit and can be removed.
- Hand-thin young fruit within about four to six weeks after bloom, leaving about 6 inches between peaches.
What to avoid
- Do not prune from fall through early winter. Cuts reduce cold hardiness and raise the risk of winter injury and canker infection.
- Avoid pruning ahead of a forecast hard cold snap.
- Do not prune so hard that you no longer need to thin fruit; that cuts the crop sharply.
Pruning window by zone
Counted from the typical last frost of each zone (the middle value among its towns of 10,000 people or more). Buds swell earlier in a warm spring, so watch the plant as well as the calendar.

| 5a | Apr 30 | Mar 19 to Apr 16 |
| 5b | Apr 28 | Mar 17 to Apr 14 |
| 6a | Apr 24 | Mar 13 to Apr 10 |

Regional notes
- Southeast: Clemson: mid-February to early March; in mountain and Piedmont areas wait until at least mid-February.
- Northeast: Penn State: not before late February.
