Ultimate Guide to Trimming Sitka Spruce

Last updated: Jan 25, 2026

Sitka Spruce trimming is a practical skill every homeowner can master to keep this iconic conifer healthy and gracefully shaped. If you're wondering how to prune Sitka Spruce or what the best time to prune Sitka Spruce is, you're in the right place.

Sitka Spruce, also called Sitka spruce or Oregon spruce, hails from the damp, coastal forests of the Pacific Northwest, from Alaska to northern California. This tall, stately evergreen is prized for its lush needles and graceful form, making it a standout in both large landscapes and urban yards. Below are its key traits to know at a glance.

  • Common names: Sitka Spruce, Sitka spruce, Oregon spruce
  • Native range: Pacific Northwest coast (Alaska to northern California)
  • Typical mature size: 60–100+ ft tall, 20–40 ft wide (varies with cultivar and site)
  • Growth rate: Moderate to fast when conditions are favorable
  • Visual characteristics: Narrow, conical silhouette; needles are dark to bluish-green and slightly stiff; bark is orange-brown and fissured; cones are slender and pointy
  • Why it’s popular: Provides substantial shade, a stately presence, good windbreak potential, and strong urban tolerance when properly maintained

Why proper trimming matters for Sitka Spruce: regular maintenance supports health, safety, and beauty. A well-structured canopy increases airflow, reduces disease pressure, and helps the tree withstand storms. It also prevents overcrowding, which can lead to weak unions and unbalanced growth. And because Sitka Spruce can grow rapidly, timely pruning helps avoid heavy, top-heavy canopies that look lopsided or risk limb breakage. Be mindful of possible issues like resin bleed after pruning and the tendency for rapid growth to crowd lower branches if not thinned appropriately.

  • Health and vigor: removes dead, diseased, or crossing wood to boost overall vitality
  • Hazard prevention: weak branches and dense canopies are thinned to reduce storm damage
  • Structural balance: selective thinning and shaping establish a strong, even silhouette
  • Disease and moisture control: improved airflow lowers humidity in the crown, reducing rot risk
  • Aesthetics: a clean, well-proportioned form that suits your landscape
  • Common challenges to guard against: avoid over-thinning or excessive pruning that can stress the tree; be mindful of sap flow and potential wound response

In this Sitka Spruce pruning guide, you’ll find practical, homeowner-friendly steps, tool recommendations, and regionally tailored tips that align with safe pruning practices. Learn when to prune, how to make clean cuts, and which techniques keep your tree growing strong without compromising its natural beauty.

Step-by-Step Sitka Spruce Trimming Techniques

Safety gear and tree assessment first: put on gloves, eye protection, and use sharp, clean tools; quickly check for deadwood, weak unions, and any hazards around the tree.

The three main pruning cuts for Sitka Spruce

  • Thinning cut — removes a branch at its origin or just outside the branch collar to open the canopy and improve air flow, light penetration, and structural clarity. Important for Sitka Spruce to reduce interior crowding without encouraging weak attachments.
  • Heading cut — removes the tip of a twig or shoot back to a bud or small branch to redirect growth. Useful for shaping or reducing overly dense, lanky growth, but can stimulate vigorous new shoots; use sparingly on spruce.
  • Reduction cut — trims a limb back to a sturdy lateral branch or bud union to decrease overall size while preserving the branch’s angle and natural habit. Keeps the tree healthy and helps control height or spread without shock to the trunk.

Step-by-step DIY trimming process

1. Plan and target the issues: identify weak branch unions, a densely crowded crown, and any growth that’s pushing the tree taller than you want. Mark priorities with chalk or ribbon so you prune purposefully, not impulsively.

2. Gather and check your gear: pruning saw or loppers, hand pruners, a pole saw if needed, a sturdy ladder, and safety gear. Keep a clear work zone, and have a partner on hand if you’re working with taller trees or high limbs.

3. Start with interior thinning cuts: remove a few crowded interior branches at their origin or just outside the branch collar to open light and air; avoid leaving bare stubs, and don’t remove more than about one-third of interior growth in a single visit.

4. Shape with selective heading cuts: for uneven or lanky outer growth, trim back tips to a healthy bud or lateral branch. Limit heading cuts on Sitka Spruce to avoid excessive dense tip growth and to keep the natural conical habit intact.

5. Reduce height or spread thoughtfully (use the 3-cut method for large limbs): if a top or long limb needs trimming, don’t shave it off in one go. Make a small underside notch to prevent bark tearing, then cut from the top just beyond the notch to relieve weight, and finally make the final cut just outside the branch collar to remove the stub. Always aim for a clean, rounded junction at the collar.

6. Clean up deadwood and undesirable growth: remove dead, broken, or crossing branches; prune water sprouts and vigorous vertical shoots that steal energy from the main framework. Step back after major removals to gauge how the tree breathes from the interior.

7. Step back, evaluate, and refine: inspect from multiple angles for balance, symmetry, and a natural silhouette. If a area still feels crowded or unbalanced, tiny follow-up cuts can fine-tune the form—do not rush a second round.

Young vs Mature Sitka Spruce: trimming guidance

  • Young Sitka Spruce: focus on building a strong scaffold. Prune gently to encourage outward branching, avoid heavy top pruning, and prioritize even spacing along the trunk. Use thinning cuts inside to improve light penetration and reduce future crowding.
  • Mature Sitka Spruce: prioritize safety, health, and long-term shape. Remove deadwood, weakly attached limbs, and heavy crossing branches gradually. Avoid removing more than about 20–25% of canopy in a single year, and prefer a series of lighter cuts over a single harsh prune.
  • General notes for both ages: always cut just outside the branch collar with a clean 30–45 degree angle, and never leave a stub. For large cuts, use the three-cut approach to control bark damage and limit tear-out, and ensure the final cut lands on healthy wood.

Last tip: step back, evaluate from multiple angles, and let the tree settle before doing any more pruning.

Essential Tools for Trimming Sitka Spruce

A well-chosen tool set makes Sitka spruce trimming safer, cleaner, and more efficient.

Hand Pruners / Secateurs

  • Best for: clean cuts on small, live shoots and sucker growth.
  • Branch size: effective up to about 1/2 inch (12 mm) in diameter; for thicker twigs, switch to loppers.
  • Species tips: use sharp bypass blades to avoid tearing live wood. Make the cut just outside the bud or at the branch collar for faster healing. Keep blades sharp and dry to prevent rust and sticking.

Loppers

  • Best for: mid-size branches and improving leverage on thicker growth without a ladder.
  • Branch size: handle roughly 1/2 to 1 1/2 inches (12–38 mm); some heavy-duty models cut up to 2 inches (50 mm) but avoid forcing through live wood near the trunk.
  • Species tips: choose bypass loppers for clean cuts; avoid crushing by rechecking the blade alignment and applying steady pressure. Use long handles to keep your hands away from the tree as you work around the crown.

Pruning Saw

  • Best for: deadwood, girdling cuts, and branches that are too thick for pruners or loppers.
  • Branch size: effective on branches roughly 1 to 3 inches (25–75 mm); for thicker limbs, switch to a pole saw or call a pro.
  • Species tips: opt for a fine-toothed, sharp blade; pull-stroke cuts give you better control and reduce kickback. Cut just outside the branch collar and avoid tearing the wood by making a clean back cut first if needed.

Pole Saw / Pruner

  • Best for: high branches beyond arm’s reach, reducing the need to climb or use ladders on tall Sitka spruces.
  • Branch size: comfortable on branches about 1 to 2 inches (25–50 mm) in diameter; some extensions handle up to about 3 inches (75 mm); very large limbs may require professional equipment.
  • Species tips: keep the pole stable and maintain a firm stance. Cut in sections, starting from the outer growth and working inward. Be mindful of sap buildup on blade and clean after each cut to prevent slipping.

Safety Gear (essential, quick reference)

  • Gloves to protect against splinters and abrasions; eye protection to shield from flying chips; a sturdy helmet with face shield when overhead pruning; solid, slip-resistant footwear to prevent slips on wet bark or mulch.

Tool Maintenance

  • Sharpening: keep blades and teeth sharp; a sharp tool makes cleaner cuts and reduces stress on the tree. Regularly hone pruners and loppers, and re-sharpen pruning saw teeth as needed.
  • Cleaning and sterilizing between cuts: wipe blades with a clean cloth and disinfect between trees to reduce disease spread in Sitka spruce. A quick wipe with isopropyl alcohol or a diluted bleach solution works well.
  • Storage: dry tools after use, coat blades with a light oil to prevent rust, and store with blades closed or sheathed to protect edges and fingers.

When to call in professionals

  • For branches thicker than about 4–6 inches (100–150 mm) or any cut that risks harming the trunk or major branches.
  • When branches are near power lines or pose a fall risk due to height or tree condition.
  • For very tall, mature Sitka Spruce trees where extensive crown work or complex rigging is required. If in doubt, professional arborists can assess structural integrity, pruning needs, and safety considerations.

Common Mistakes to Avoid When Trimming Sitka Spruce

Topping or Top-Pruning

  • What it is: Removing the very top of the tree or repeatedly cutting the leaders to stubs to reduce height.
  • Why it's harmful to Sitka Spruce: Sitka spruce relies on a single strong central leader and a natural conical shape. Topping disrupts that architecture, often triggering a flush of weakly attached shoots from the cuts and exposing interior wood to sun damage.
  • Consequences: Weak, uneven regrowth; increased risk of limb breakage in wind; larger wounds that heal slowly and invite pests or disease; a top-heavy crown that becomes unstable.
  • Alternative: Use gradual reduction cuts over several years. Limit height by shortening the top leader only to a robust lateral branch, making cuts just outside the branch collar and keeping the central leader intact whenever possible.

Over-Pruning (Removing Too Much Foliage in One Go)

  • What it is: Cutting away a large portion of live needles and shoots in a single session.
  • Why it's harmful: Sitka spruce stores energy in its foliage. Heavy cuts deprive the tree of photosynthesis, slow recovery, and stress the root system.
  • Consequences: Dieback, weak new growth, increased susceptibility to pests and disease, and an unattractive, sparse canopy.
  • Alternative: Prune in small, incremental steps across multiple years. Target only dead, damaged, crossing, or rubbing branches; avoid removing more than a small fraction of live foliage in a year.

Flush Cuts

  • What it is: Cutting directly against the trunk or removing a branch flush without leaving the branch collar intact.
  • Why it's harmful: The wound is large and exposed, and Sitka spruce heals slowly from such cuts.
  • Consequences: Decay and disease entry at the wound, reduced long-term vigor, and less natural wound closure.
  • Alternative: Always cut just outside the branch collar. Leave a clean, smooth wound size that the tree can compartmentalize and seal over time.

Stub Cuts

  • What it is: Leaving a stub by cutting inside the limb or stopping short of the branch collar.
  • Why it's harmful: A stub dries out or dies back, creating an entry point for pests and disease.
  • Consequences: Deadwood and decay radiating from the stub, potential branch failure, and ongoing maintenance trouble.
  • Alternative: Make clean cuts flush with the branch collar, removing the limb back to healthy wood.

Heading Cuts

  • What it is: Cutting a branch back to a point inside the canopy rather than to a lateral bud or side branch.
  • Why it's harmful: This produces dense, weakly structured shoots rather than a balanced growth pattern.
  • Consequences: Poor form, future pruning headaches, and increased risk of breakage in wind or ice.
  • Alternative: Remove branches back to a side branch or use a proper reduction cut to maintain strength and natural shape.

Lion-Tailing

  • What it is: Removing interior growth so only the outer ends retain needles (a “ticker-tape” crown).
  • Why it's harmful: It reduces even distribution of foliage and photosynthetic capacity; interior growth provides wind resistance and overall health.
  • Consequences: Top-heavy, weakly attached leaders, ragged appearance, and higher breakage risk.
  • Alternative: Thin evenly across the canopy, removing only crossing or rubbing growth. Preserve a balanced interior to maintain a healthy crown.

Pruning at the Wrong Time

  • What it is: Pruning when the tree is stressed by heat, drought, or late in the growing season.
  • Why it's harmful: Wounds heal slowly in hot or wet conditions; growth cycles can be disrupted.
  • Consequences: Persistent wounds, increased disease pressure, and poor callus formation.
  • Alternative: Plan pruning for late winter to early spring while the tree is dormant, avoiding extreme heat or drought periods and hot, rainy seasons.

Dull or Dirty Tools

  • What it is: Using blunt blades or tools contaminated with soil or plant material.
  • Why it's harmful: Torn tissue heals poorly and dirty tools spread pathogens.
  • Consequences: Slower healing, higher infection risk, and unsightly pruning scars.
  • Alternative: Sharpen and disinfect tools between cuts; wipe blades with a disinfectant or alcohol and prune cleanly with fresh cuts.

When Is the Best Time to Trim Sitka Spruce?

Timing matters as much as the cut itself. Prune Sitka Spruce when the tree is least stressed to promote clean wounds and quick recovery.

Primary pruning window for most Sitka Spruce: the dormant season—late winter to early spring before bud break. Pruning then minimizes stress, supports faster wound closure, makes structure easier to see, and lowers disease or pest risk.

Best Time Window for Sitka Spruce

Late winter to early spring, before bud break.

  • Why this window works: the tree is not actively growing, so cuts heal more cleanly and quickly. Energy is stored in the roots and trunk, which helps wounds close with less surge of new growth. Visibility of scaffold limbs is clearer, allowing better planning and safer cuts.
  • When to expect the least disruption: pruning in dormancy reduces stress and the chance of attracting pests looking for fresh wounds.

Seasonal Guidelines

  • Best overall time: late winter to early spring before bud break. Benefits include reduced stress, quicker wound healing, easier assessment of limb structure, and lower disease/pest risk.
  • Acceptable alternatives:
  • Light corrective pruning in summer for minor issues (e.g., removing a diseased limb or clearing crowded interior branches).
  • Immediate pruning for dead, damaged, or hazardous branches at any time to protect the tree and property.
  • Times to strictly avoid:
  • Late fall: higher risk of fungal spore activity and wound infection as conditions cool and damp.
  • Active growing season for heavy cuts on a spruce: large, flush cuts during vigorous growth can stress the tree and slow healing.
  • Summer heat or drought: pruning during extreme conditions increases water stress and reduces wound closure efficiency.

Sitka Spruce-Specific Notes

  • Sap flow and pruning: Sitka Spruce doesn’t typically “bleed” sap as dramatically as maples or birches, but large wounds in winter can dry and crack if temperatures swing. Keep cuts moderate and avoid heavy, multi-branch removals in deep cold.
  • Temperature considerations: avoid long, exposed wounds when it's very cold or icy, and avoid heavy cuts during heat waves that accompany drought.
  • Summer pruning: if you must prune in summer, keep cuts small, targeted, and prioritize removing dead or broken branches to minimize stress.
  • Health and pest considerations: pruning away dead wood helps reduce disease opportunities; structural pruning is best done gradually to preserve the tree’s natural form.

Influencing Factors

  • Local climate/region:
  • In milder zones, the window can begin earlier in late winter.
  • In colder climates, wait until mid- to late winter to protect new tissue from late freezes.
  • Tree age/health:
  • Younger trees tolerate pruning better and recover more quickly.
  • Older or stressed trees may require smaller, staged cuts and closer attention to overall structure.
  • Current conditions:
  • Avoid pruning in drought, after a hurricane or heavy storms, or during prolonged wet spells that keep wounds exposed to disease.

Quick Signs Your Sitka Spruce Needs Trim Soon

  • Dead or diseased branches
  • Crossing or rubbing limbs
  • Excessive height or canopy crowding
  • Poor lateral structure or weak scaffold growth
  • Storm damage or interior limbs with poor airflow

If you’re unsure, consider a professional assessment. A quick, well-timed prune keeps Sitka Spruce healthier, safer, and looking its best, season after season.

Different regions call for regionally tuned trims—timing, wound care, and airflow priorities shift with climate.

Pacific Northwest

  • Timing: Prune during late winter to early spring while the tree is dormant. Typical window: late February through March. Avoid wet, showery springs to minimize disease exposure.
  • Canopy work: Favor light shaping and removal of dead or crossing branches rather than big structural cuts. Preserve the natural conical form.
  • Airflow and disease: In humid coastal climates, open up the canopy a bit to improve air movement and reduce fungal pressure. Remove diseased wood promptly and sanitize tools between cuts.
  • Bleeders and nearby species: If you have maples or other sap-bleeding trees nearby, avoid summer pruning on those species; coordinate your landscape work so Sitka Spruce cuts stay in the dormant window.
  • Practical homeowner tips: Mulch around the root zone to protect moisture during summer dry spells, and water deeply during dry spells. Inspect for pests after trimming, especially bark beetles or spruce aphids.
  • Local tips: Common in rainy Portland or Seattle? Check our Pacific Northwest city guides for more localized advice.
  • Visual placeholders: Insert map of U.S. climate zones with Sitka Spruce highlights here. Photo of a well-pruned Sitka Spruce in a Pacific Northwest yard.

Alaska and Subarctic Regions

  • Timing: Prune in late winter to early spring after severe freezes pass but before new growth begins. Avoid mid-winter pruning during the coldest snaps.
  • Snow load and structure: Cut weak, high-weight limbs to reduce snow load risk, and tidy up any branches that could break under heavy snow.
  • Growth and stress: Sitka Spruce often grows slowly here; make small, incremental reductions rather than drastic size changes to minimize transplant shock.
  • Wound care: Let wounds callus naturally; avoid heavy use of pruning sealants in these climates.
  • Pests and sanitation: While disease pressure is lower than in humid zones, monitor for spruce beetle activity and keep pruning debris cleaned up to reduce attractants.
  • Practical homeowner tips: Keep a mulch ring and regular deep watering during dry spells; protect tender roots with organic mulch as soils freeze-thaw.
  • Local tips: Common in Anchorage or Fairbanks? See Alaska city guides for micro-regions.
  • Visual placeholders: Insert photo of Sitka Spruce in subarctic yard. Insert regional pest photo if applicable.

Northeast and Great Lakes

  • Timing: Late winter to early spring is ideal, after hard frosts but before budbreak. Avoid pruning in mid-winter when soils are frozen.
  • Canopy work: Focus on removing deadwood, fixing crossing limbs, and opening the canopy to improve airflow.
  • Disease prevention: In humid, hot summers, aggressive pruning late spring or summer can invite needle blight and canker; keep cuts small and compact. Sanitize blades between trees.
  • Species interactions: In humid mixed forests, winter-only windows are recommended for oaks and other disease-prone companions; plan Sitka pruning accordingly.
  • Practical homeowner tips: Monitor for spruce budworm in late summer; use light pruning hedges rather than heavy thinning. Keep soil evenly moist, especially after pruning.
  • Local tips: Common in Boston, New York, or Philadelphia? Check our Northeast city guides for localized tips.

Mountain West and Inland Northwest

  • Timing: Short growing season calls for pruning in late winter to early spring, avoiding late-spring frost risk.
  • Drought-aware trimming: Favor lighter cuts to reduce water demand; avoid removing large interior limbs that stress the tree in dry years.
  • Airflow and structure: Remove interior branches to improve air movement, but avoid excessive thinning that compromises vigor.
  • Species interactions: In drier climates with nearby deciduous trees, summer pruning can increase sap loss and stress; schedule around those considerations.
  • Practical homeowner tips: Water after trims if soils are dry, and mulch to conserve soil moisture. Watch for pests in hot summers.
  • Local tips: Denver or Boise tips? See Mountain West city guides for localized advice.
  • Visual placeholders: Insert landscape photo showing a lightly thinned Sitka Spruce in a dry-region yard. Insert climate map placeholder.

Southeast & Humid Subtropics

  • Timing: Winter pruning is preferred (January–February) to avoid heat and disease pressure; avoid pruning in wet heat periods.
  • Canopy strategy: Open the crown to improve airflow and reduce humidity pockets that foster disease.
  • Disease and pests: Humid climates raise needle blight and canker risk; remove diseased wood promptly and sanitize tools. Do not leave fresh wounds exposed to heavy rains.
  • Practical homeowner tips: Mulch after cuts to retain soil moisture; monitor for pests (spruce beetles and borers) after trimming.
  • Local tips: Common in Asheville, Atlanta, or Charlotte? Check Southeastern city guides for localized adjustments.
  • Visual placeholders: Photo of Sitka Spruce thriving in a mountain-Southeast landscape. Insert regional climate map.

Eco-friendly regional practices to consider: after trimming, leave clean wood chips around the base or chipped branches as mulch where allowed; these practices conserve soil moisture, support soil biology, and provide habitat for beneficial insects and wildlife in your region.

Care And Maintenance for Sitka Spruce

Watering Tips

  • Young trees (first 1–2 years): water regularly during dry spells. A deep soak 1–2 times per week helps establish a strong root system. Aim to moisten the soil to a depth of roughly 12–18 inches.
  • Established trees: prefer deep, infrequent watering. During droughts, soak every 2–3 weeks rather than daily light watering; use a soaker hose or slow-drip method to encourage deep root growth.
  • Deep vs. frequent: a thorough soak that reaches the root zone is better than short, shallow waterings. This builds resilience and helps Sitka spruce tolerate seasonal stress.
  • Seasonal adjustments: increase watering in hot, dry summers; reduce or pause in cool, wet climates once rainfall is steady. In coastal or high-rain areas, you may not need supplemental irrigation after establishment.
  • Signs of trouble: under-watered trees show drooping or bronze-tinted needles, needle tips browning, and dry soil that pulls away from the edges of the mulch ring. Over-watering shows as yellowing needles, soggy soil, a musty smell, or mushy, discolored roots.
  • Sitka-specific note: keep soil consistently moist but not waterlogged. A layer of mulch helps maintain even moisture around the root zone.

Mulching

  • Benefits: mulch improves moisture retention, reduces weed competition, moderates soil temperature, and supports a healthy micro‑environment for roots.
  • How to apply: spread 2–4 inches of organic mulch (shredded bark, wood chips, or pine needles) over the root zone. Extend the mulch ring outward to at least the drip line if possible.
  • Placement: keep mulch away from the trunk by a few inches to prevent rot and pest issues. Do not mound mulch into a volcano around the base.
  • Best materials: use well-aged or composted mulch; avoid freshly chipped material that can rob nitrogen or invite decay organisms.
  • Sitka note: because Sitka spruce roots are relatively shallow, consistent mulching helps protect roots from temperature swings and moisture loss.

Fertilization & Soil

  • Soil testing: start with a soil test every 2–3 years to determine nutrient needs and pH. Follow the test results for fertilizer type and rate.
  • When to fertilize: apply in early spring as growth begins, or after the soil has thawed. Avoid late-summer or fall feeding that may promote new growth vulnerable to winter damage.
  • Type of fertilizer: use slow-release or time-released formulations, or organic options (e.g., composted matter, feather/blood meal) based on soil test results. Apply evenly over the root zone and water in well.
  • Nitrogen caution: avoid excessive nitrogen. Sitka spruce benefits from balanced or slightly lower nitrogen inputs; too much N can encourage rapid, weak growth and increase pest vulnerability.
  • Signs of nutrient issues: pale or yellowing needles (especially older growth), stunted growth, or interveinal chlorosis indicate potential deficiencies. Adjust fertilization accordingly after soil testing.
  • Sitka-specific tip: keep pH in the mildly acidic range (roughly 5.5–6.5) for optimal nutrient availability. Adapt fertilizer type and rate to soil conditions and tree size.

Pest & Disease Monitoring

  • Common threats: spruce bark beetles and other bark beetles; aphids and spruce gall adelgids; fungal issues such as Cytospora canker and Rhizosphaera needle cast; root rot pathogens (Armillaria, Phytophthora) in poorly drained soils.
  • Early signs: thinning crown, resin flow or pitch tubes on the trunk, small exit holes, sticky honeydew, distorted or yellowing needles, cankers on branches, or wet, sunken root zones.
  • Prevention: promote tree vigor with proper watering and mulching; ensure good airflow by avoiding dense, overcrowded planting; prune to remove crowded or crossing limbs; keep tools clean to avoid spreading disease.
  • When to act: for minor issues, prune affected limbs and sanitize tools. For widespread thinning, persistent needle cast, or signs of cankers or root rot, consult a certified arborist for diagnosis and treatment options.

Other Routine Care

  • Winter protection: in exposed sites, protect young trees from desiccation by wind and sun with a lightweight barrier or windbreak; avoid heavy wrapping that traps moisture. Water adequately late fall to reduce winter drought stress.
  • Storm prep and recovery: inspect after storms for broken or leaning branches; prune damaged limbs promptly to reduce further injury and pest entry points.
  • Grass and vegetation control: keep a clear, weed-free zone around the trunk (1–2 feet) to reduce competition for water and nutrients; mulch helps with this and reduces mower damage.
  • Girdling roots and trunk health: periodically check for circling or girdling roots near the soil line. If you see roots wrapping around the trunk or tight root masses, call an arborist to evaluate and correct.
  • Pruning basics: minimal pruning is often best. If needed, perform light pruning in late winter to early spring before new growth.
