Shrub Problems Solved
Residential shrub pruning problems we solve throughout the NH Seacoast & Southern Maine
Most residential shrub problems develop gradually—overgrowth blocking windows, declining health from improper care, uneven shapes from repeated shearing, and plantings outgrowing their spaces. At Expert Pruning, we've spent 25+ years solving these problems using methods grounded in plant biology rather than quick fixes that create new issues.
Each problem requires a different approach. Overgrown shrubs need staged renovation. Unhealthy shrubs require diagnosis before cutting. Misshapen growth needs selective thinning, not more shearing. Shrubs blocking access need reduction to strong laterals, not topping. Understanding these differences produces lasting solutions.
Restoring Overgrown & Neglected Shrubs
Bringing severely overgrown plantings back to manageable size
We often see foundation plantings that have consumed windows, hedges that have merged into solid walls, and specimen shrubs that dominate entire beds. The instinct is to cut everything back hard, but severe reduction all at once often kills the plant or creates years of weak regrowth.
Our approach uses staged renovation over two to three seasons. First-year work removes no more than one-third of the plant, focusing on oldest stems at ground level. This allows light into the interior and stimulates dormant buds lower on the plant, producing controlled new growth rather than explosive water shoots.
🌱 Our Renovation Process
Year One: Remove up to one-third of oldest growth at base. Thin crossing branches. Allow plant to respond and assess vigor.
Year Two: Continue selective removal, shaping emerging growth. Reduce height gradually to strong laterals, never to stubs.
Year Three: Fine-tune form. Establish maintenance schedule that prevents future overgrowth—typically one pruning annually.
For shrubs with good regeneration capacity—lilacs, forsythia, spirea, viburnums—we can be more aggressive with ground-level removal. For plants that regenerate poorly—most needled evergreens, hollies, azaleas—we work conservatively, never cutting past green growth. Species identification drives the approach
A row of yews had grown to block first-floor windows completely, requiring expensive interior lighting during daylight hours. Previous contractors quoted removal and replacement at $4,200. We renovated over two seasons using selective reduction, bringing the hedge to four feet while maintaining density. Total cost: $840 over two years, and the mature hedge now needs only annual maintenance.
Diagnosing & Restoring Unhealthy Shrubs
Identifying causes of decline before pruning
⚠️ When NOT to Prune
Active dieback from disease or environmental stress. Severe nutrient deficiency (yellowing throughout plant). Recent transplant shock. Root damage from construction or soil compaction.
Action: Address underlying cause first. Allow recovery. Prune only dead wood until plant stabilizes.
✅ When Pruning Helps
Dense interior blocking light and air. Crossing branches creating wounds. Old unproductive wood on flowering shrubs. Recovery after pest/disease treatment.
Action: Light selective thinning improves air circulation. Remove damaged tissue. Limit to 15–20% removal on stressed plants.
We often see shrubs with yellowing leaves, sparse growth, dieback, or failure to flower—and the property owner's first instinct is to prune hoping to stimulate recovery. In most cases, pruning an already-stressed shrub makes decline worse. Unhealthy shrubs need diagnosis first, intervention second.
Common causes include poor drainage, compacted soil, nutrient deficiencies, disease or pest pressure, and damage from salt or drought. Each requires a different solution. We assess site conditions, examine soil, check for pests or disease, and evaluate recent weather before recommending any cutting.
For shrubs declining from compacted soil or poor drainage, we recommend soil amendment and aeration before pruning. For drought stress, we establish deep watering and wait for recovery. For pest or disease issues, we coordinate treatment timing—pruning diseased wood only after the problem is controlled, always disinfecting tools between cuts.
Our Diagnostic Approach
- Assess overall plant vigor and pattern of decline
- Examine soil conditions: drainage, compaction, pH
- Check for pest or disease indicators on leaves, stems, roots
- Evaluate site factors: light exposure, wind, salt exposure, recent disturbance
- Determine if pruning will help or harm given current plant state
- Address root causes before cutting, or work in coordination with treatment

Correcting Misshapen Shrubs
Restoring natural form through selective pruning
Misshapen shrubs usually result from repeated shearing with hedge trimmers or uneven access to sunlight. We see foundation plantings shaped into dense "meatballs" with bare interiors, one-sided shrubs etiolated toward light sources, and plants with gaps from storm damage or disease that never filled back in. Each pattern requires different correction strategies.
Shrubs repeatedly sheared develop a dense outer shell with no interior branching. When this shell is opened through selective thinning, light reaches dormant buds on interior wood, stimulating new growth that fills the plant from inside out. This takes two to three seasons but produces lasting natural form.
🎯 Selective Pruning Approach
For over-sheared shrubs: We thin the outer shell gradually, making cuts back to interior laterals rather than shearing tips. Light penetrates, dormant buds activate, interior fills naturally. Plant develops balanced branching throughout rather than just a surface layer of foliage.
For one-sided growth: We prune the dense side more heavily to redirect energy toward sparse areas. Remove competing growth. The plant rebalances over one to two seasons as resources flow to areas with less foliage.
For gappy or damaged areas: We assess whether the plant can regenerate in the gap or if relocation/replacement makes more sense. Some gaps close with patient selective work; others indicate the plant has outgrown suitability for the location.
Clearing Windows, Walkways & Entrances
Size reduction without creating long-term problems
✂️ Proper Reduction Technique
Identify target height based on clearance needs (window sills, walkway edges, entry visibility). Trace branches from tips back to suitable laterals at target height. Make clean cuts just above lateral junctions—never to stubs. Work branch by branch, never shearing across the top. Result: controlled size with strong structure and slower regrowth.
Shrubs blocking windows, pathways, or building access create both aesthetic and functional problems. The common solution is topping at the desired height, but this creates weak regrowth that returns faster than the original plant, requiring more frequent cutting and escalating costs.
Our approach uses reduction cuts to strong lateral branches. When we reduce a branch to a lateral that's at least one-third the diameter of the removed section, that lateral becomes the new growing point. The plant accepts this redirection without producing the explosive weak shoots that topping triggers.
For shrubs that have completely outgrown the space—mature sizes of 8-12 feet planted under 4-foot windows—we discuss whether ongoing reduction is cost-effective or if relocation and appropriate species selection makes more sense. Constantly fighting a plant's mature size creates perpetual expense. Sometimes the best solution is moving the plant to a suitable location and choosing a naturally compact species for the original spot.
A commercial property had topped foundation shrubs annually for eight years, spending $1,200 each visit to maintain window clearance. Within six months, regrowth blocked windows again. We removed the unsuitable species (rapid-growing burning bush) and installed compact evergreens with 3–4 foot mature heights. After installation cost of $2,800, the property now spends $300 annually on light maintenance—a 75% reduction in ongoing costs.
Why Our Solutions Last
Plant biology over quick fixes
All our shrub solutions work with plant biology rather than fighting it. Staged renovation respects recovery capacity. Diagnosis addresses root causes. Selective thinning maintains natural branching. Reduction cuts avoid triggering stress responses. These methods produce results that last years rather than months, with lower maintenance costs and healthier plants over time.
