Tree & Shrub Pruning Service

SOP Process Updated Jun 19, 2026 ยท Lawn Care

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

  1. 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."
  2. 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
  1. 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

  1. 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
  1. 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.
  2. Three D's first: Dead, Damaged, Diseased - remove these on every plant regardless of season.
  3. Then crossing branches that rub each other (one will eventually wound the other).
  4. Then shape. Light shaping cuts; don't remove > 25 % of live wood in a year.
  5. 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.
