Tree & Shrub Pruning Service
Purpose
Define the residential tree + shrub pruning service. Bad pruning kills plants OR creates lifelong scarring; correct pruning maintains health, shape, and bloom productivity. The variability is in WHEN and WHAT - different species need different timing, different cuts. This SOP covers the standard ornamental + landscape work; large-tree work + storm cleanup are separate.
Scope
Applies to:
- Ornamental shrubs and small trees (boxwood, holly, yews, viburnum, etc.)
- Flowering shrubs (hydrangea, lilac, forsythia, azaleas)
- Small ornamental trees < 25 ft tall (Japanese maple, dogwood, crepe myrtle)
- Residential hedges + screen plantings
Excludes large-tree work (anything requiring climbing or aerial lift - refer to certified arborist), and pruning of fruit trees in active commercial production (specialty service).
Responsibilities
- Dispatcher confirms species + customer expectations at booking; flags any "I want it taken down hard" requests for the experienced lead to consult on
- Lead technician runs the protocol; helps less-experienced crew identify species + cuts
- Customer is briefed on the right time to prune any plants we DIDN'T touch this visit
Procedure
- Customer briefing. "We'll prune what's appropriate for this time of year and let me know what each plant is - some plants we shouldn't touch this season."
- Identify each plant + when to prune it (rough rule, varies regionally):
- Spring-flowering shrubs (forsythia, lilac, azalea, rhododendron): prune AFTER bloom; pruning now removes next year's flower buds
- Summer-flowering shrubs (hydrangea paniculata, butterfly bush, panicle): prune in late winter / early spring
- Boxwood + holly + yew: prune any time; severe rejuvenation in early spring
- Hedges: shear 2 - 4x per season; major reshaping in late winter
- Japanese maple: light prune late winter; never remove > 25 % in a single year
- Tool selection by stem diameter:
- < 1/2": bypass hand pruner
- 1/2 - 1.5": bypass loppers
- 1.5 - 4": pruning saw
-
4": refer to arborist
- Three-cut rule for branches over 1" diameter - prevents bark tearing:
- First cut: 6" from trunk, undercut 1/3 through the bottom
- Second cut: 1 - 2" further out, cut down through the top (branch falls)
- Third cut: at the branch collar, clean
- Cut at the branch collar. Never flush-cut (kills the tree's healing ability). The branch collar is the swollen ridge where the branch meets the trunk; cut just outside it.
- Three D's first: Dead, Damaged, Diseased - remove these on every plant regardless of season.
- Then crossing branches that rub each other (one will eventually wound the other).
- Then shape. Light shaping cuts; don't remove > 25 % of live wood in a year.
- Clean up. Bag clippings or chip on-site per customer preference. Sweep walkways + driveways.
Acceptance Criteria
- Each plant pruned per its seasonally-appropriate guidance
- No flush cuts; all cuts at branch collar
- No more than 25 % live-wood removal on any single plant
- Clippings cleaned up; walkways swept
- Customer signs the field report with notes on what was + wasn't touched this season
"Topping" a tree (cutting back all branches uniformly to a stub height) is NOT pruning - it's a horticultural malpractice that creates structurally-weak regrowth and shortens the tree's life. If a customer requests topping, push back firmly: "Topping causes long-term damage. I can do a corrective prune that addresses your concern (height, view, etc.) without topping." If they insist, refuse the work or refer them to a different shop. Your reputation is downstream of every customer's tree health.
