How & When to Prune Trees and Shrubs

A Practical Pruning Guide for Bay Area Gardens

Pruning can improve plant structure, remove damaged growth, manage size, increase light and airflow, and help trees and shrubs fit their landscape.

But pruning is not simply about cutting a plant back.

The right timing and method depend on the plant, its age, why you are pruning it, and how it grows.

A good general rule is:

Know why you are making each cut before you make it.

Why Prune?

Plants may be pruned for several different reasons.

Remove Dead, Damaged, or Diseased Growth

Dead or damaged branches can often be removed when they are identified.

Removing problem branches can improve appearance and prevent damaged wood from interfering with healthy growth.

Improve Structure

Young trees can sometimes benefit from selective structural pruning that encourages a strong framework as they mature.

Good structure early in a tree's life can reduce the need for larger corrective cuts later.

Manage Size

Pruning can help manage plants growing near:

  • Buildings

  • Walkways

  • Windows

  • Fences

  • Driveways

  • Neighboring properties

  • Other plants

Pruning should work with the plant's natural growth habit rather than repeatedly forcing a large plant into a space that is too small.

Improve Light & Airflow

Selective thinning can allow more light and air through dense growth.

Avoid removing excessive foliage simply to "open up" a tree.

Maintain Hedges & Screens

Hedges and privacy plants often need regular shaping to maintain the desired height, width, and density.

Support Flowering or Fruit Production

Some flowering and fruiting plants benefit from specific pruning methods.

Timing matters because different plants produce flowers or fruit on different types of growth.

Before You Prune

Ask four questions:

1. What plant is this?

Different species respond differently to pruning.

2. Why am I pruning it?

Are you removing dead wood, controlling size, shaping a hedge, improving structure, or managing fruit production?

3. Is this the right season?

Timing can affect flowering, fruiting, new growth, and plant stress.

4. Can I safely reach the branch?

If the work requires climbing, large equipment, or working near structures or utility lines, professional help may be appropriate.

When Is the Best Time to Prune?

There is no single pruning season for every plant.

Timing depends on what you are pruning and what you want to accomplish.

Winter

Dormant-season pruning is common for many deciduous trees and fruit trees.

With the leaves gone, branch structure can also be easier to see.

However, not every plant should receive heavy winter pruning.

Late Winter & Early Spring

This is a common pruning period for many deciduous plants before or around the beginning of active spring growth.

Timing should still be based on the specific species.

Spring

Be careful with spring-flowering plants.

Many flowering shrubs and trees form flower buds before spring.

Pruning them immediately before flowering can remove much of that year's bloom.

For many spring-flowering plants, pruning after flowering may be more appropriate.

Summer

Summer pruning can sometimes be used for:

  • Light shaping

  • Managing vigorous growth

  • Removing unwanted shoots

  • Controlling size

  • Maintaining hedges

Avoid unnecessary heavy pruning during extreme heat or when a plant is already stressed.

Fall

Heavy pruning is often avoided in fall when it may encourage tender new growth before cooler weather.

Light corrective work or removal of damaged material may still be appropriate depending on the plant and conditions.

Understand How Your Plant Flowers

Before pruning a flowering plant, determine whether it blooms on older wood or new growth.

Plants That Flower on Older Growth

Some plants form flower buds on growth produced during the previous season.

Pruning at the wrong time can remove those buds.

Plants That Flower on New Growth

Other plants produce flowers on the current season's growth.

Their pruning timing can be different.

This is why a single pruning calendar does not work for every flowering shrub.

Basic Types of Pruning Cuts

Removal Cut

A branch is removed back to an appropriate branch junction or its point of origin.

This is commonly used for removing dead, damaged, crossing, or unwanted branches.

Reduction Cut

A branch is shortened back to an appropriate lateral branch.

This can help reduce length while maintaining a more natural branch structure.

Heading Cut

A branch or shoot is shortened without removing it back to a major branch junction.

Heading can stimulate new growth near the cut and is commonly used in certain shrubs and hedges.

It should be used intentionally rather than as the default method for every tree.

Where to Make a Pruning Cut

When removing a branch, avoid cutting randomly through the middle of the branch.

For many tree branches, the cut should be made just outside the natural branch collar without leaving a long stub or cutting flush into the trunk.

Correct cut placement can support the tree's natural response to pruning.

The Three-Cut Method for Larger Branches

A heavier branch can tear bark if it is removed with a single cut.

For branches that can be safely handled from the ground, the three-cut method can reduce this risk.

First Cut

Make an undercut partway through the branch away from the final cut location.

Second Cut

Make a second cut farther out to remove most of the branch weight.

Final Cut

Remove the remaining stub at the appropriate branch collar.

If the branch is large, high, heavy, or difficult to control safely, stop and use a qualified professional.

How Much Should You Prune?

Avoid removing large amounts of healthy canopy without a clear reason.

The amount a plant can tolerate depends on:

  • Species

  • Age

  • Health

  • Season

  • Type of pruning

  • Growing conditions

The commonly repeated "25% rule" should not be treated as a target.

Removing less is often better.

Make the cuts that are actually needed and reassess the plant before continuing.

Pruning Young Trees

Young trees are often easier to train than mature trees are to correct.

Early structural pruning may focus on:

  • Removing damaged branches

  • Addressing crossing or rubbing branches

  • Developing appropriate structure

  • Managing competing stems when appropriate

  • Maintaining a balanced canopy

Avoid aggressively removing healthy branches simply to make a newly planted tree look more "finished."

The leaves help the young tree produce energy while it establishes.

Newly Planted Trees

A newly planted tree generally does not need heavy pruning simply because it was planted.

Focus first on:

  • Correct planting depth

  • Root establishment

  • Watering

  • Stability

  • Overall plant health

Remove broken or damaged branches when needed.

Major shaping can often wait until the plant begins establishing.

See our Planting Guide

Pruning Mature Trees

Mature trees require more caution.

Large cuts can permanently change tree structure and create significant wounds.

Common mature-tree objectives may include:

  • Deadwood removal

  • Clearance

  • Structural correction

  • Selective reduction

  • Managing damaged branches

Large-tree pruning is not a good DIY project when climbing, rigging, chainsaws, or work over structures is involved.

Pruning Fruit Trees

Fruit-tree pruning depends heavily on the species.

Apples, pears, peaches, plums, cherries, figs, persimmons, citrus, and other fruit trees should not all be pruned the same way.

Pruning may be used to:

  • Develop structure

  • Manage height

  • Improve light penetration

  • Remove damaged wood

  • Manage fruiting wood

  • Make harvesting easier

Before pruning a fruit tree, identify the species and understand how it produces fruit.

Deciduous Fruit Trees

Many deciduous fruit trees are commonly pruned during dormancy, but the correct method varies.

For example, different fruit species produce crops on different ages and types of wood.

Excessive pruning can reduce fruit production or stimulate vigorous vegetative growth.

Citrus

Citrus generally does not require the same routine heavy dormant pruning used for many deciduous fruit trees.

Pruning is often focused on:

  • Dead or damaged branches

  • Unwanted shoots

  • Clearance

  • Size management

  • Access

Avoid unnecessarily opening the canopy or removing large amounts of healthy foliage.

Japanese Maples

Japanese maples are valued for their natural branch structure.

Pruning should usually be selective.

Common goals include:

  • Removing dead branches

  • Correcting crossing growth

  • Improving visibility of the branch structure

  • Light shaping

Avoid turning a naturally graceful Japanese maple into a heavily sheared form.

Flowering Trees & Shrubs

Timing is especially important for flowering plants.

Before pruning, determine when the plant flowers and where its flower buds develop.

Pruning immediately before bloom can remove much of the display you were trying to improve.

For many spring-flowering shrubs, pruning after flowering is a useful general approach.

Hedges & Privacy Plants

Hedges often need more regular pruning than specimen trees.

Common goals include:

  • Maintaining height

  • Controlling width

  • Encouraging density

  • Keeping pathways clear

  • Maintaining a clean outline

Whenever possible, avoid allowing the upper part of a hedge to become much wider than the lower part.

A broader base can help light reach lower foliage.

Privacy Trees

Plants used for screening should not automatically be topped at the desired final height.

The correct approach depends on the species and the type of screen you are trying to create.

Before pruning, consider:

  • Desired final height

  • Desired width

  • Natural plant form

  • Density

  • Neighboring structures

  • Long-term maintenance

Roses

Rose pruning depends on the type of rose and the local growing season.

Pruning may include:

  • Removing dead or weak growth

  • Improving structure

  • Managing size

  • Removing crossing stems

  • Encouraging productive new growth

Climbing roses, shrub roses, and other rose types may require different methods.

Suckers & Water Sprouts

Some trees produce vigorous shoots from the base, roots, trunk, or branches.

Before removing them, identify why they are occurring.

For grafted plants, growth emerging from below the graft union may come from the rootstock rather than the desired cultivar.

Dead, Diseased & Damaged Branches

Damaged branches can often be addressed when discovered.

Look for:

  • Broken branches

  • Dead wood

  • Rubbing branches

  • Split limbs

  • Diseased-looking tissue

If disease is suspected, identify the problem before doing extensive pruning.

Some plant diseases require more specific timing or sanitation practices.

Should Pruning Tools Be Disinfected?

Clean, sharp tools make better cuts.

Tool sanitation can also be important when working with plants where disease transmission is a concern.

The appropriate cleaning method depends on the plant and disease risk.

At minimum, avoid moving obviously contaminated plant material from one plant to another with dirty tools.

Choose the Right Tool

Hand Pruners

Useful for smaller stems and detailed pruning.

Loppers

Provide additional leverage for somewhat larger branches that can still be safely handled by hand.

Pruning Saw

Useful for branches too large for hand pruners or loppers.

Hedge Shears

Designed for shaping appropriate hedge material rather than structural tree pruning.

Always use tools appropriate for the size of the branch.

Do not force a small hand tool through wood it was not designed to cut.

Common Pruning Mistakes

Topping Trees

Cutting major branches back indiscriminately to reduce tree height can damage structure and create weak, vigorous regrowth.

Better: Use appropriate reduction techniques or professional evaluation.

Removing Too Much at Once

Heavy pruning can stress a plant and dramatically change its growth response.

Better: Remove only what is needed.

Cutting Too Close to the Trunk

Flush cuts can damage trunk tissue.

Better: Preserve the appropriate branch collar.

Leaving Long Stubs

Long branch stubs do not create good final cuts.

Better: Make the cut at the appropriate branch junction.

Pruning Every Plant at the Same Time

Different plants have different flowering, fruiting, and growth cycles.

Better: Prune according to the plant.

Using Dull Tools

Dull blades can crush or tear plant tissue.

Better: Keep pruning tools clean and sharp.

Topping a Tree to Keep It Small

A tree that is naturally too large for its location may require repeated aggressive pruning.

Better: Choose an appropriately sized plant whenever possible.

When to Call a Professional

Consider professional help when pruning involves:

  • Large branches

  • Tall mature trees

  • Climbing

  • Chainsaw work above ground

  • Branches over buildings

  • Branches near utility lines

  • Storm-damaged trees

  • Significant structural defects

  • Large-scale canopy reduction

  • Work requiring rigging or specialized equipment

Do not attempt work near energized utility lines.

Frequently Asked Questions

When is the best time to prune trees in the Bay Area?

It depends on the species and the reason for pruning.

Many deciduous trees are commonly pruned during dormancy, while flowering trees and shrubs may need different timing.

Can I prune a tree in summer?

Light pruning and size management may be appropriate for some plants during summer.

Avoid unnecessary heavy pruning during extreme heat or when the tree is stressed.

Should I prune a newly planted tree?

Usually only as needed for broken, damaged, or clearly problematic branches.

A newly planted tree needs healthy foliage while its root system establishes.

How much of a tree can I remove at once?

There is no percentage that should be treated as a pruning goal.

Remove only what is necessary and avoid excessive canopy loss.

Should I seal pruning cuts?

Routine pruning cuts generally should not automatically be covered with wound paint or sealant.

Some specific pest or disease situations may require different practices.

When should I prune flowering shrubs?

It depends on when the plant forms flower buds.

Many spring-flowering shrubs are commonly pruned after flowering so the current bloom is not removed.

Can I top a tree to make it shorter?

Topping is generally not a good way to manage mature tree height.

Appropriate reduction pruning or professional evaluation is usually a better approach.

Do citrus trees need annual pruning?

Not necessarily.

Citrus often needs relatively limited pruning compared with many deciduous fruit trees.
