Late-winter pruning: what to cut now
Late winter is the standard pruning window for most deciduous trees and shrubs in the Northeast. The structure is easy to see without leaves, the worst cold is usually over, and wounds start closing as soon as growth begins in spring. Per UMass Extension, how a shrub flowers decides when to cut it.
Prune from late February through March:
- Summer-flowering shrubs that bloom on new wood: panicle and smooth hydrangeas, rose-of-Sharon, summer-blooming spirea, beautyberry. See pruning hydrangeas by type.
- Deciduous shade and ornamental trees: remove dead, crossing and rubbing branches and narrow-angled leaders. Maples and birches may bleed sap if cut now. It looks alarming but does not harm the tree.
- Oaks: prune only in the dormant season. The New York State DEC asks residents not to prune oaks from April through July because of oak wilt.
Do not prune yet: forsythia, lilac, rhododendron, azalea, early spirea and bigleaf hydrangea. All have already set their flower buds. Roses, ornamental grasses and butterfly bush wait for March, as covered in the March guide.
Fruit trees, blueberries and grapes
Per UMass Extension's fruit pruning basics, dormant pruning of tree fruit starts in late winter. The goal is a strong framework and an open canopy where light reaches the fruiting wood and leaves dry quickly after rain.
- Apples and pears first: start with the oldest, largest trees on mild days in late February and work through March. Remove dead and diseased wood, water sprouts, and branches growing straight up or back toward the center. Cornell's fruit team recommends a few large, well-chosen cuts over many small ones. Hold off while hard freezes are still forecast; the March guide notes that pruning during stretches below 35°F at night raises the risk of wound injury.
- Peaches and nectarines last: these are pruned closest to bloom, since late-winter cuts on stone fruit are more prone to cold injury and canker.
- Blueberries: per UConn's blueberry pruning guide, remove the oldest, least productive canes at the base each winter, along with low, spreading and weak twiggy growth. See how to prune blueberries.
- Grapes: prune hard while dormant. Most of last year's growth comes off, leaving a set number of buds on renewal canes or spurs. Pruning late in the dormant season reduces the risk of cold injury.
Our fruit tree pruning guide covers the cuts in detail.
Felco F-2 bypass pruners
February and March are the busiest pruning weeks of the year in the Northeast, and sharp bypass pruners make the clean cuts that fruit trees, blueberries and summer-blooming shrubs need. See how we chose it.
Dormant oil: get ready, but check the conditions
Horticultural oil applied before bud break smothers overwintering scale insects, mite eggs and aphid eggs on fruit trees and ornamentals. Per Michigan State University Extension, oils are among the lowest-risk pesticides for beneficial insects, but timing and weather matter:
- Apply on a calm, dry day when the temperature is above 40°F and is not forecast to drop below freezing for the next 24 hours.
- Spray before buds open. In zone 7 that is late February into March. In zones 5–6, usually March, as the March guide notes.
- Only spray trees and shrubs with a known pest problem, such as scale on euonymus or magnolia, or mites and scale on fruit trees. Dormant oil is not a routine treatment.
- Check the label for plants that oil can injure. Blue-needled conifers such as blue spruce lose their blue color.
Seed starting: onions, leeks, peppers
Follow the calendar you built in January, counting back from your last frost date:
- Zone 7 (Long Island, NYC; last frost around April 1–7): peppers and eggplant from mid-February to March 1. Onions and leeks should already be up. Tomatoes wait until March.
- Zone 6 (Hartford, coastal CT, much of NJ and PA): onions, leeks and celery in early-to-mid February, then peppers and eggplant in late February or early March.
- Zone 5 (Albany, inland New England): onions and leeks in mid-to-late February. Peppers wait until early March.
Per Cornell Cooperative Extension, germinate peppers and eggplant warm (bottom heat helps), then move seedlings to cooler air under strong light. Water from below, run a small fan for air movement, and thin to one seedling per cell. See our seed starting guide for the full setup.
Cool-season transplants and forced branches
The frost-tolerant crops come next. Broccoli, cabbage, kohlrabi, lettuce and other cool-season transplants go outside several weeks before the last frost, so they are started indoors well ahead of the tomatoes:
- Zone 7: sow broccoli, cabbage and lettuce for transplants in mid-to-late February. They go out under row cover in late March, when the March guide's cool-season planting window opens.
- Zones 5–6: sow them in March for April planting.
- Order seed potatoes and onion sets now if you have not. Plant them when the soil reaches about 45°F.
Force flowering branches. UConn's February gardening tips include forcing branches of spring-flowering shrubs indoors. Cut stems of forsythia, flowering quince, pussy willow or cherry on a mild day, recut the ends under water, and stand them in a vase in a cool, bright room. They bloom in a few weeks. Take the stems from places you would thin out anyway. The rest of the shrub still gets pruned after it flowers.
Soil prep and early-season setup
February thaws tempt gardeners into the beds too early. The squeeze test in the March guide applies: if a handful of soil holds a ball and does not crumble when poked, it is too wet to dig. Working wet soil damages structure for the whole season.
- Spread compost on beds whenever the ground is frozen or firm enough to walk on without leaving deep footprints. Work it in later.
- Build or repair raised beds and cold frames now. A cold frame set up in February warms the soil for early lettuce and spinach in March on Long Island.
- Order lime only if a soil test called for it. Apply it once the ground thaws.
- Do not fertilize the lawn yet. Suffolk County and New York State prohibit lawn fertilizer until April 1, and New Jersey's homeowner blackout lasts until March 1.
Pests and animal damage to watch
- Spotted lanternfly egg masses: keep scraping them off bark, stone and outdoor furniture until the eggs hatch in late spring. Per Penn State Extension, scrape them into alcohol or hand sanitizer.
- Deer: late winter is often the hungriest time for deer. Keep netting on high-value shrubs and reapply repellents on mild days. The March guide explains how to rotate products.
- Rabbits and voles: as snow melts, check young trees for chewed bark at the base and repair or raise trunk guards.
- Salt: once beds thaw, a few deep waterings help leach salt out of root zones beside driveways and walks.
Common mistakes
| Mistake | Consequence | Correct approach |
|---|---|---|
| Pruning forsythia, lilac or rhododendron in February | Cuts off this spring's flowers | Prune spring bloomers right after they flower |
| Pruning peaches at the same time as apples | More cold injury and canker on stone fruit | Prune peaches and nectarines last, close to bloom |
| Spraying dormant oil on a cold or freezing day | Poor coverage and possible plant injury | Spray above 40°F with no freeze in the next 24 hours, before bud break |
| Starting tomatoes in February | Overgrown transplants long before outdoor conditions allow | Start tomatoes 6–8 weeks before last frost |
| Digging beds during a thaw | Compaction and clods that last all season | Use the squeeze test; wait until the soil crumbles |
| Topping trees to reduce their size | Weak, crowded regrowth and decay | Thin by removing whole branches back to a junction |
Frequently asked
Is February too early to prune fruit trees?
Late February is the start of the window in most of the Northeast, especially for large apple and pear trees that take a while to prune. Avoid pruning right before a forecast deep freeze, and save peaches for last. If you have only a couple of trees, March is equally good.
Can I prune my maple even though it bleeds sap?
Yes. Sap flow from late-winter cuts on maples and birches looks bad but does not harm the tree. If it bothers you, those species can be pruned in early summer after the leaves fully expand.
When do I start peppers on Long Island?
Mid-February to March 1, which is 8–10 weeks before the zone 7 last frost of around April 7. Peppers are slow to germinate and grow. Use bottom heat for germination and strong light afterward.
Should I remove winter mulch in February?
Not yet. Its job is to keep the soil frozen through February thaws. Pull it back gradually in March and April as new growth starts, and keep some nearby in case of a hard frost.
