Seacoast NH Pruning Calendar | Portsmouth & Exeter
Seasonal pruning guidance for Portsmouth, Exeter, and the NH Seacoast
Pruning timing matters, but it is not a rigid set of dates on a calendar. Plants respond to light, temperature, dormancy, and growth cycles, and those factors shift slightly each year. Our pruning calendar for the NH Seacoast is designed as a seasonal framework, allowing us to adapt pruning decisions to each plant and each season rather than forcing work into fixed windows.
Homeowners in Portsmouth, North Hampton, Greenland, Exeter, and surrounding Seacoast communities benefit most when pruning follows plant biology instead of habit. This page outlines how we approach pruning throughout the year and why timing—especially winter pruning—plays such a critical role in long-term plant health.
Why Seasonal Timing Matters
Plants do not grow evenly throughout the year. Energy storage, bud formation, flowering, and structural growth all occur in specific seasonal phases, and pruning interacts directly with those processes. Cutting at the wrong time can reduce flowering, weaken structure, or trigger excessive regrowth.
Our team adjusts pruning plans based on the season, the plant species, and the goal of the work. An Exeter property that shifted from summer-only pruning to our seasonal calendar approach saw lilac flowering increase by approximately 60% and reduced annual maintenance visits from four to two—cutting pruning costs nearly in half. Timing is a tool, not a rule, and knowing when to wait is often just as important as knowing when to cut.
📅 Seasonal Pruning Quick Reference
- Spring: Assessment, cleanup, and post-bloom pruning for spring-flowering shrubs
- Summer: Size control, water sprout removal, and selective thinning
- Fall: Light cleanup only—avoid heavy structural work
- Winter: Major structural pruning, renovation, and long-term correction
Spring Pruning Guide
Spring pruning focuses on assessment, cleanup, and selective correction rather than heavy reduction. As plants break dormancy, we can clearly see winter damage, crossing branches, and structural issues that affect growth moving forward. This is also when flowering habits become especially important.
Shrubs such as lilac, forsythia, and magnolia are evaluated carefully, since many bloom on old wood and should only be pruned after flowering. In Portsmouth and Exeter landscapes, spring pruning is often light and intentional, setting plants up for balanced growth through the rest of the season.
Summer Pruning Guide
Summer pruning is about control and refinement, not renewal. We use this season to manage size, remove water sprouts, and correct fast-growing areas before they become problems. Done properly, summer pruning can reduce the need for heavier work later.
Evergreen shrubs like holly, boxwood, and arborvitae, as well as foundation plantings, often benefit from selective summer thinning. In warmer Seacoast areas such as North Hampton and Greenland, we remain conservative to avoid heat stress and unnecessary regrowth.
Fall Pruning Guide
Fall pruning requires restraint and clear purpose. While light cleanup and the removal of damaged or hazardous branches can be appropriate, most structural pruning is limited as plants begin shifting energy into roots and storage. Cutting too much at this stage can interfere with winter hardiness.
Deciduous shrubs and small ornamental trees are evaluated rather than aggressively pruned. Fall is often used to plan winter pruning work, especially for overgrown shrubs or structural issues that are best addressed during dormancy.

Winter Pruning Guide
Winter pruning is one of the most important—and most overlooked—seasons for residential landscapes. During dormancy, plant structure is fully visible, energy reserves are stable, and the risk of stress-induced regrowth is lowest. This makes winter the ideal time for major structural pruning and long-term correction.
Shrubs such as apple, crabapple, maple, dogwood, and many foundation shrubs respond exceptionally well to winter pruning. In Seacoast NH communities like Portsmouth and Exeter, winter work allows us to shape plants thoughtfully, reduce size safely, and set the stage for healthier spring growth.
❄️ Why Winter Pruning Is Ideal
- Full visibility: Deciduous plants are bare, revealing branch structure completely
- Stable energy reserves: Plants in dormancy tolerate removal better than during active growth
- Minimal stress response: Low risk of excessive regrowth or water sprouts
- Disease prevention: Many pathogens are dormant, reducing infection risk
- Property access: Frozen or snow-covered ground protects lawns and beds from equipment
Adapting the Calendar to Your Landscape
No two properties follow the calendar exactly. Sun exposure, wind, soil conditions, and plant maturity all influence how and when pruning should occur. Our seasonal approach allows us to adapt timing while staying grounded in plant biology.
This flexibility is especially important for established residential landscapes, where past pruning history often dictates what can be done safely in any given season.
