Job Overview
This chapter qualifies you to prune a controlled group of shrubs and one small ground-accessible tree according to health, structure, clearance, and seasonal objectives. The finished work product is a set of correctly pruned plants with dead, diseased, and structurally unsound growth removed, proper cuts made at the branch collar, natural form preserved, canopy removal held within the approved limit, and a documented pruning record.
You will identify each plant and its pruning season, flowering habit, growth form, and objective; inspect for dead, diseased, broken, crossing, rubbing, weak, hazardous, and overextended branches; identify overhead hazards; inspect and sanitize tools; establish a debris and exclusion zone; remove dead, broken, and diseased growth first; make proper collar cuts and three-cuts on larger limbs; remove crossing and rubbing branches; thin shrubs from the interior; apply heading cuts only where appropriate; maintain plant-specific height, spread, and flowering-wood goals; avoid over-pruning and topping; remove suckers and water sprouts where appropriate; inspect the finished structure from multiple viewpoints; and document the work performed.
This chapter follows Chapter 1 through Chapter 16 in the book sequence. The plants pruned in this chapter were selected, sited, and planted in Chapters 8 through 10 and are maintained afterward under the fertilizing and watering cycle in Chapter 18. This chapter does not replant, relocate, or redesign any planting bed; it works only with the plant structure already established on site.
Skills You Will Demonstrate
- LS-097 — Identify the pruning objective for each plant based on species, season, flowering habit, and growth form.
- LS-098 — Remove dead, diseased, broken, and hazardous growth using sanitized tools.
- LS-099 — Make proper pruning cuts at the branch collar, including the three-cut method for larger limbs.
- LS-100 — Shape shrubs using thinning and heading cuts appropriate to the plant and objective.
- LS-101 — Avoid over-pruning by holding canopy removal within the approved limit and never topping a tree.
- LS-102 — Inspect finished plant structure from multiple viewpoints and document the pruning performed.
Where This Skill Fits
This chapter depends on the plant identification, spacing, and mature-size information recorded in Chapter 1 and applied during planting in Chapters 8 through 10. It uses the tool-inspection and sanitation habits introduced across the book and connects directly to Chapter 18, where fertilizing and watering decisions are informed by the plant condition observed here.
Pruning performed under this chapter does not replace specialist tree care. Any plant condition that exceeds the scope defined below is referred out rather than pruned under this chapter's authorization.
Scope and Intended Use
This chapter covers:
- identifying pruning season, flowering habit, growth form, and objective for each plant before cutting
- inspecting for dead, diseased, broken, crossing, rubbing, weak, hazardous, and overextended branches
- inspecting and sanitizing hand pruners, loppers, and saws
- establishing a debris drop and exclusion zone
- making proper collar cuts, including the three-cut method for branches large enough to tear bark
- removing crossing and rubbing branches and thinning shrubs from the interior
- using heading cuts only where compatible with the plant and objective
- maintaining plant-specific height, spread, flowering wood, and privacy goals within the approved canopy-removal limit
- removing suckers and water sprouts where appropriate
- inspecting structure from multiple viewpoints and documenting the work performed
This chapter does not authorize the learner to:
- prune large limbs, work from ladders with chainsaws, work near power lines, work above safe ground-access height, or prune storm-damaged or structurally unstable trees
- climb, use aerial equipment, or perform any pruning that requires a qualified tree-care professional
- make flush cuts, leave long stubs, top a tree, remove canopy beyond the approved limit, or apply wound paint unless specifically directed
- shear a plant that requires natural-form pruning, or apply heading cuts to a plant or objective for which they are not appropriate
Any condition exceeding this scope is referred to a qualified tree-care professional before any cut is made in that area.
Reference Conventions
Establish these references before pruning begins, and do not change them mid-project.
| Term | Definition |
|---|---|
| Branch collar | The slightly raised area where a branch joins a larger branch or trunk; the correct cut location for branch removal |
| Flush cut | A cut made too close to the trunk or parent branch that removes the branch collar; a prohibited cut in this chapter |
| Heading cut | A cut that shortens a branch to a bud or lateral branch, used only where compatible with the plant and objective |
| Thinning cut | A cut that removes an entire branch back to its point of origin, used to open the plant interior without stimulating dense regrowth |
| Three-cut method | The undercut, top cut, and final collar cut sequence used on branches large enough to tear bark if cut in a single pass |
| Approved canopy-removal limit | The maximum proportion of live canopy that may be removed in a single pruning cycle for the identified plant and objective |
| Debris drop zone | The marked area where cut material is dropped and contained during pruning |
Project and Reference Record
Before beginning the work, record the project identification directly on the pruning log:
Property address: ______________________ Plant group or bed reference: ______________________
Date started: ____________ Pruner name: ____________ Landscape Readiness Worksheet reference: ______
Prerequisites
- Access to the Landscape Readiness Worksheet plant identification, location, and mature-size notes from Chapter 1
- Confirmed identification of each plant's species, pruning season, and flowering habit
- Inspected and sanitized hand pruners, loppers, and pruning saw
- A marked debris drop and exclusion zone
- Confirmed absence of power lines, roofs, or other overhead hazards within reach of the pruning work, or confirmation that any such condition has been referred to a qualified tree-care professional
Common Field Fundamentals
Every pruning cut made in this chapter depends on four fundamentals: the correct objective for the specific plant, a sanitized and appropriate tool for the cut size, the correct cut location at the branch collar, and a canopy-removal limit that is never exceeded in a single cycle.
Objective and SeasonSpecies, flowering habit, growth form, and correct pruning window confirmed before cutting
Hazard ScreeningOverhead lines, roofs, unstable trunks, and storm damage identified before work begins
Tool SanitationPruners, loppers, and saws inspected and sanitized before use and between diseased plants
Removal OrderDead, diseased, and broken growth removed first, then structural and shaping cuts
Cut PlacementCollar cuts and the three-cut method used correctly on every applicable branch
Canopy LimitLive canopy removal held within the approved limit; no topping or flush cuts
Objective, Hazard Screening, and Stop-Work Conditions
Identify each plant and confirm pruning season, flowering habit, growth form, and objective before any cut is made. Identify power lines, roofs, windows, traffic, ladders, and overhead hazards within reach of the work. Stop work for large limbs, elevated chainsaw work, storm-damaged trees, power-line proximity, unstable trunks, or climbing requirements, and refer the condition to a qualified tree-care professional.

| Documentation | Every plant in the work group has a completed pruning-log entry with species, date, objective, and canopy percentage removed |
E. Preparation — Identification, Hazards, and Tool Setup
- Identify each plant and confirm pruning season, flowering habit, growth form, and objective. Record each on the pruning log before cutting.
- Inspect for dead, diseased, broken, crossing, rubbing, weak, hazardous, and overextended branches. Mark each condition found on the plant or in the log.
- Identify power lines, roofs, windows, traffic, ladders, and overhead hazards. Confirm the work can be completed entirely from safe ground access.
- Stop work for large limbs, elevated chainsaw work, storm-damaged trees, power-line proximity, unstable trunks, or climbing requirements. Refer any such condition to a qualified tree-care professional before continuing in that area.
- Inspect and sanitize hand pruners, loppers, and saws. Confirm cutting edges are sharp and clean before the first cut.
- Establish a debris drop and exclusion zone. Keep the zone clear of bystanders, pets, and unrelated tools.
F. Corrective and Structural Cuts
- Remove dead, broken, and diseased growth first. Cut back to healthy wood or to the point of origin as the condition requires.
- Make cuts just outside the branch collar. Confirm the collar location before each cut.
- Do not make flush cuts or leave long stubs. Recheck cut placement immediately after each cut.
- Use the three-cut method for branches large enough to tear bark. Make the undercut, the top cut, and the final collar cut in sequence.
- Remove crossing and rubbing branches selectively. Choose the branch with the weaker structure or poorer position for removal.
- Thin shrubs from the interior where appropriate. Remove selected branches back to their point of origin to open the plant without stimulating dense regrowth.
- Use heading cuts only where compatible with the plant and objective. Cut to a bud or lateral branch facing the intended growth direction.
- Do not shear plants that require natural-form pruning unless specified. Confirm the objective before applying any shearing cut.
G. Form Control, Sucker Removal, and Documentation
- Maintain plant-specific height, spread, flowering wood, and privacy goals. Reference the objective recorded in Section E, Step 1.
- Avoid removing more live canopy than the approved limit. Track cumulative removal as cutting proceeds.
- Do not top trees. Confirm the leader and primary scaffold branches remain intact.
- Remove suckers and water sprouts only where appropriate. Cut back to the point of origin.
- Inspect structure from multiple viewpoints. Walk around the plant and check the result from at least two sides.
- Clean tools between diseased plants where required. Sanitize before moving to the next plant showing disease symptoms.
- Remove debris and document pruning performed. Complete the pruning log for every plant in the work group.
Common Inspection Review
Review every pruned plant using the same checks regardless of species or bed location.
- Cut-placement check: confirm every cut is at the branch collar, with no flush cuts and no long stubs.
- Canopy-limit check: confirm no plant exceeds the approved canopy-removal limit for this cycle.
- Topping check: confirm no tree has been topped and no leader has been removed without justification.
- Sanitation check: confirm tools were sanitized before use and between diseased plants.
- Form check: confirm each plant's natural form is preserved unless shearing was specified.
- Documentation check: confirm every plant has a completed pruning-log entry.

Failure Points and Troubleshooting
Cleanup
This chapter ends with cleared debris, sanitized tools, and a completed pruning log retained for the maintenance record, not scattered clippings and an unrecorded visit.
- Remove all cut debris from the debris drop zone and the surrounding planting bed
- Separate compostable plant debris from diseased material requiring separate disposal
- Clean and sanitize hand pruners, loppers, and saws before storage
- Store tools dry and protected from the elements
- File the completed pruning log with the Landscape Readiness Worksheet where Chapter 18 can reference it
Field Terms
- Branch Collar
- The slightly raised area where a branch joins a larger branch or trunk; the correct cut location for branch removal.
- Flush Cut
- A cut made too close to the trunk or parent branch that removes the branch collar.
- Heading Cut
- A cut that shortens a branch to a bud or lateral branch.
- Thinning Cut
- A cut that removes an entire branch back to its point of origin.
- Three-Cut Method
- The undercut, top cut, and final collar cut sequence used on larger branches.
- Water Sprout
- Vigorous, often vertical growth arising from a branch, typically removed where inappropriate to the plant's form.
- Sucker
- Vigorous growth arising from the root system or base of the plant, typically removed.
- Approved Canopy-Removal Limit
- The maximum proportion of live canopy that may be removed in a single pruning cycle for the identified plant and objective.
Skill Check
- Why must the pruning objective, season, and flowering habit be identified before any cut is made?
- What conditions require the pruning work to stop and be referred to a qualified tree-care professional?
- Where is the correct location for a branch-removal cut, and what two errors does this chapter prohibit at that location?
- When is the three-cut method required, and what does each of the three cuts accomplish?
- What is the difference between a thinning cut and a heading cut, and when is each appropriate?
- Why does this chapter set an approved canopy-removal limit, and what must happen if that limit is reached mid-project?
- Why must tools be sanitized between diseased plants?
- Why does this chapter require inspecting the pruned plant from multiple viewpoints rather than one?
- Under what conditions are suckers and water sprouts removed?
- Why does this chapter prohibit topping a tree under any circumstance?

Performance Check
With all eight sections of the pruning log completed, review the finished work against the Acceptance Standards table and confirm every cut is placed correctly at the branch collar, no flush cuts, long stubs, or topped trees are present, canopy removal is within the approved limit for every plant, tools were sanitized as required, natural form is preserved unless shearing was specified, and every plant has a documented log entry. If any deficiency remains, correct or refer it and repeat the affected section review before closing the project.
Project Closeout
You have completed the seventeenth chapter in the landscaping project sequence: pruning shrubs, small trees, and overgrown plantings. This chapter required you to identify the pruning objective for each plant (LS-097), remove dead growth (LS-098), make proper pruning cuts (LS-099), shape shrubs (LS-100), avoid over-pruning (LS-101), and inspect plant structure (LS-102).
You now have a group of correctly pruned shrubs and a small tree with preserved natural form, controlled canopy removal, and a documented pruning record. That record carries directly into the next chapter: fertilizing, watering, and maintaining these same plantings using the condition observations made here.
File your completed pruning log with the Landscape Readiness Worksheet where Chapter 18 can reference it. Chapter 18 begins from the plant condition documented in this chapter.
