Winter pruning is the default for most deciduous fruit trees and ornamentals because the plant is dormant, the branch structure is visible, and cuts heal quickly once spring growth begins. UC Agriculture and Natural Resources recommends dormant-season pruning (December through February) for apple, pear, stone fruit, and grape in California's Central Coast climate. Summer pruning has its place for specific goals, but if you only prune once a year, winter is the safer bet.
When to Prune in Winter
Winter is the time for structural pruning: removing crossing branches, shaping the canopy, cutting out dead wood, and opening up the center of fruit trees for light and air circulation. With the leaves gone, you can see exactly what needs to go. This is when you make the big, decisive cuts that define your tree's shape for the year ahead.
For apple, pear, plum, and peach trees in Santa Cruz, prune in January or early February, after the coldest nights have passed but before buds start swelling. Grapevines should be pruned hard in late January. Roses get their major pruning in mid-January on the coast. One important exception: avoid pruning apricots and cherries in wet weather, as they are highly susceptible to bacterial canker. Wait for a dry spell, even if that means pruning in late February.
When to Prune in Summer
Summer pruning is your tool for controlling size, removing water sprouts (those vigorous vertical shoots), and thinning to improve fruit quality. If a fruit tree is growing too tall or too wide, summer pruning will slow that growth without triggering the aggressive regrowth response that winter pruning causes.
This is also the season to prune citrus, which should never be heavily pruned in winter. In Santa Cruz, citrus trees grow year-round and are best pruned lightly in late summer (August or September) to remove dead twigs, thin dense interior growth, and shape the canopy. For fig trees, summer pinching of branch tips in June encourages a second crop of figs in the fall. Consider summer pruning as the fine-tuning complement to winter's heavy structural work.
The Bottom Line for Santa Cruz Gardeners
Prune deciduous fruit trees in winter (January through mid-February) for structure, and again lightly in summer (June through August) for size control. If you skip one, skip summer. The winter pruning session is the one that really shapes your tree's productivity and health. For citrus, do your pruning in late summer instead. Keep pruning tools sharp and clean, and make cuts just outside the branch collar. And if you are unsure about a cut, leave it. You can always take more off later, but you cannot put a branch back.
This week: Sharpen your hand pruners and loppers. Clean the blades with rubbing alcohol. Mark your calendar for a winter pruning day in January, and take 10 minutes to study the branch structure of your fruit trees while the leaves are still on so you can plan your cuts.

Frequently Asked Questions
Should I prune my fruit trees in winter or summer?
Winter is the default for most deciduous fruit trees. UC Agriculture and Natural Resources recommends dormant-season pruning from December through February for apple, pear, stone fruit, and grape on the Central Coast. If you only prune once a year, choose winter.
What is winter pruning best for?
Structural work: removing crossing branches, shaping the canopy, cutting out dead wood, and opening the center for light and air. In Santa Cruz, prune apple, pear, plum, and peach in January or early February, but avoid pruning apricots and cherries in wet weather to prevent bacterial canker.
When should I prune citrus trees?
Citrus should never be heavily pruned in winter. In Santa Cruz, prune citrus lightly in late summer, around August or September, to remove dead twigs, thin dense interior growth, and shape the canopy.
What is summer pruning good for?
Summer pruning controls size, removes water sprouts, and thins to improve fruit quality without triggering the aggressive regrowth that winter pruning causes. June through August, after the spring growth flush, is the window in Santa Cruz.
