4.10 YOUNG TREE PRUNING

The reasons for young tree pruning may include, but are not limited to, reducing risk, maintaining or improving tree health and structure, improving aesthetics, or satisfying a specific need. Young trees with a potential to grow into a utility space should be removed or relocated.

4.10.1. AT PLANTING

Pruning should be limited to cleaning

Branches should be retained on the lower trunk.

4.10.2. ONCE ESTABLISHED

A central leader or leader(s) as appropriate should be developed.

A strong, properly spaced scaffold branch structure should be selected and maintained.

Rubbing and poorly attached branches should be removed.

Interfering branches should be reduced or removed.

Cleaning should be performed

4.10.3. SPECIALITY PRUNING TYPES

Consideration shall be given to the ability of a species to tolerate these types of pruning.

4.10.3.1. Espalier

Branches that extend outside the desired plane of growth shall be pruned or tied back.

Ties should be replaced as needed to prevent girdling the branches at the attachment site.

4.10.3.2. Pollarding

Consideration shall be given to the ability of the individual tree to respond to pollarding.

Management plans shall be made prior to the start of the pollarding process for routine removal of water sprouts.

Internodal cuts shall be made at specific locations to start the pollarding process. After the initial cuts are made, no additional internodal cut shall be made.

Water sprouts growing from the cut ends of branches (knuckles) should be removed annually during the dormant season.

4.10.3.3 Restoration

Restoration shall consist of selective pruning to improve the structure, form, and appearance of trees that have been severely headed, vandalized, or damaged.

Size range of parts, location in tree, and percentage of water sprouts to be removed should be specified.

4.10.3.4 Vista pruning

Vista pruning shall consist of selective pruning to allow a specific view.

Size range of parts, location in tree, and percentage of foliage to be removed should be specified.

4.10.4 PALM PRUNING

Palm pruning should be performed when fronds, fruit, or loose petioles may create a dangerous condition (can cause fire risk).

16

Live healthy fronds, initiating at an angle of 45 degrees or greater from the horizontal plane, should not be removed.

Fronds removed should be severed close to the petiole base without damaging living trunk tissue.

Palm peeling (shaving) should consist of the removal of only the dead frond bases at the point they make contact with the trunk without damaging living trunk tissue.

The use of climbing spurs is prohibited as the spurs leave wounds in the palm tree trunk that never heal in time, and are susceptible to disease and other illnesses.

4.10.5 UTILITY PRUNING

4.10.5.1 General

The purpose of utility pruning is to prevent the loss of service, comply with mandated clearance laws, prevent damage to equipment, avoid access impairment, and uphold the intended usage of the facility/utility space.

4.10.5.2 Utility crown reduction pruning

A pruning cut that removes a branch at its point of origin shall be made close to the trunk or parent limb, without cutting into the branch bark ridge or collar, or leaving a stub.

A pruning cut that reduces the length of a branch or parent stem should bisect the angle between its branch bark ridge and an imaginary line perpendicular to the branch or stem.

The final cut shall result in a flat surface with adjacent bark firmly attached.

When removing a dead branch, the final cut shall be made just outside the collar of living tissue.

Tree branches shall be removed in such a manner so as not to cause damage to other parts of the tree or to other plants or property. Branches too large to support with one hand shall be pre-cut to avoid splitting of the wood or tearing of the bark. Where necessary, ropes or other equipment shall be used to lower large branches or portions of branches to the ground.

A final cut that removes a branch with a narrow angle of attachment should be made from the bottom of the branch to prevent damage to the parent limb.

A minimum number of pruning cuts should be made to accomplish the purpose of facility/utility pruning. The natural structure of the tree should be considered.

Trees directly under and growing into the facility/utility space should be removed or pruned. Such pruning should be done by removing entire branches or by removing branches that have laterals growing into (or once pruned, will grow into) the facility/utility space.

Trees growing along the side and growing into or toward the facility/utility space should be pruned by removing entire branches. Branches that, when cut, will produce water sprouts that would grow into facilities and/or utility space should be removed.

Branches should be cut to laterals or the parent branch and not at a pre-established clearing limit. If clearance limits are established, pruning cuts should be made at laterals or parent branches outside the specified clearance zone.

4.10.5.3 Mechanical pruning

Cuts should be made close to the main stem, outside of the branch bark ridge and branch collar. Precautions should be taken to avoid stripping or tearing of bark or excessive wounding.

17

4.10.5.4 Lateral / Directional pruning

Involves the pruning of a leader back to a lower outward-growing limb (lateral).

For a tree growing directly under a power line the leader is drop-crotched to lower laterals. The top laterals are further pruned to direct subsequent growth away from the conductors.

Branches growing above the conductors are directed up and away from the conductors while those below are directed down and back. Plant growth regulators may be applied in applicable cases.

4.11 ACCEPTABLE PRUNING TECHNIQUES

The following figures have been reproduced from “Arboriculture: Integrated Management of Landscape Trees, Shrubs, and Vines” by Richard W. Harris, 2

nd edition. Some of the figures

have been modified in the interests of clarity.

Heading back

Figure 1: Heading back

Heading back is defined as pruning to a stub (lower branch), a small lateral (trunk) or a bud (terminal on small lateral). Heading back affects both the appearance and the growth of the tree. New growth is usually vigorous, upright and dense.

The value of heading back is therefore questioned with respect to utility pruning.

18

Thinning out

Figure 2: Thinning out

Thinning out is the removal of a lateral branch at its point of origin, or the shortening of a branch by cutting to a lateral large enough to assume the terminal role.

Reducing the height of a tree by thinning the terminal to a large lateral is also known as drop-crotching.

Drop-crotching is the preferred means of pruning.

The lateral to which a branch or trunk is cut should have at least one third to one half the diameter of the cut being made. Half is preferred.

Little or no stub remains.

The response to thinning is distributed more evenly throughout the plant than is the response to heading. The plant becomes more open but retains its natural form. Growth is less vigorous after thinning, compared to heading.

Pruning cuts

Figure 3: Pruning cuts

Flush cuts are not recommended due to their size and the resultant exposure of trunk tissue to the possibility of decay.

19

Natural target pruning (NTP) is the preferred means.

Pruning cuts are made close to, but beyond the bark ridge and the collar at the base of the branch.

With respect to Figure 3:

a) Left figure

Applied when the location of the branch bark ridge (A) and bark collar (B) are readily located.

Remove the limb by making the final cut (A-B) just to the outside of the branch bark ridge and collar.

b) Centre figure

Applied where the branch collar is not visible or the position of the collar needs to be verified.

2 methods to estimate the cut:

i. Estimate line (A-B) which is parallel to the branch to be removed, estimate the line of the bark ridge (A-C) – the angle formed between the lines (A-B) and (A-C) equals the angle of the line (A-E) with respect to line (A-C). [Alternatively, angle BAC should equal angle CAE].

ii. Obtain the line of the bark ridge (A-C), estimate the path of the imaginary vertical line (A-D) from point A – the angle formed between the imaginary line (A-D) and line (A-C) of the bark ridge equals the angle between the imaginary line (A-D) and the proposed cut-line (A-E). [Alternatively angle CAD should equal angle DAE].

The pruning cuts are made just outside the bark ridge and branch collar.

If the remaining stub is longer than wanted and / or the final pruning cut with a chain saw must be upwards because of the angle of the cut, the pruning cut can be made outside the branch ridge through the branch collar.

c) Right figure

Relevant to drop-crotching

The final cut is to be made along line (A-C).

Locate the branch bark ridge (A-D) and the line perpendicular to the branch to be removed by the cut (A-B).

Line (A-C) bisects the angle formed by the lines (A-D) and (A-B).

If in doubt, cut closer to line (A-B) than line (A-D). Cutting too close to (A-D) will weaken the remaining limb or branch attachment.

20

Application of hook-and-blade shears

Figure 4: application of hook-and-blade shears to small branches

Close cuts can be made by placing the blade against the bark ridge of the limb to be removed. A closer cut is achieved by placing the blade against the trunk, branch or limb that is to remain.

Close cuts reduce the number of shoots that may grow near the pruning cut.

To avoid splitting out when thinning a terminal to a lateral – leave a short stub and cut upwards.

Avoid crushing plant tissue with the anvil of the shears by ensuring the blade is keen, and utilising the correct cutting procedures.

With respect to Figure 4 – less effort is required when the blade cuts up (left pane) or diagonally (center pane), instead of down. Diagonal cuts must be 5 mm above the bud (right pane, indicated by the red arrow).

Figure 5: Application of hook-and-blade shears when cutting back to laterals.

With respect to Figure 5, place the anvil of the shears in the crotch and cut up parallel to the direction of the lateral. The blade of the shears should be keen. Leave a short stub so that the branch bark ridge of the lateral is not injured or cut. The correct procedure is indicated in the left pane with the affirming tick .

Failure to adhere to this technique will usually result in tragedy (right pane).

21

Hiding pruning cuts

Figure 6: Hiding pruning cuts from view

Attempts should be made in all cases to hide pruning cuts from view. This can be achieved by angling the cuts away from the direction of most frequent observation – typically pedestrian traffic or location-specific infrastructure.

Removal of large limbs

Figure 7: removal of limbs larger than 50 mm in 3 steps

This technique should be considered for branches larger than 25 mm, and is mandatory for branches larger than 50 mm in diameter.

The first cut is made on the underside of the branch approximately 300 mm from the crotch. The depth of the cut shall be 25% of the branch diameter. The second cut is then made within 25 mm of the first cut, on the top side of the limb – until the limb falls off. The second cut must be made further along the branch (further from the crotch) than the first cut – will prevent splitting.

The 3rd

cut neatens matters, and is placed just beyond the branch bark ridge – as discussed in pruning above.

22

Removal large branch: sharp angle of attachment

Figure 8: removal of a large branch with a sharp angle of attachment

The final point of attachment must be determined (A) and the cut must slope at approximately 40 to 50 degrees from the horizontal. The branch and the trunk are not united between (A) and (B).

Removal of dead branch stubs

Figure 9: Removal of dead branch stubs

A dead branch stub that has a collar of live wood should be cut just at the outer edge of the collar.

23

Shoot removal (sharp angle of attachment)

Figure 10: Shoot removal

On young trees, shoots with sharp angles of attachment or included bark should be pruned off when they are 150-200 mm long. A second bud will usually form a shoot with less vigour than the more upright shoots, and will grow at a wider angle free of included bark.

Temporary branches as protection

Figure 11: Temporary branches as protection

Branches below the lowest permanent branch will strengthen and protect the trunk. When young trees have not yet reached the desired height of the lowest scaffold, treat laterals as temporary branches. Remove vigorous laterals if less vigorous laterals can be selected.

24

The laterals can protect the trunk from the effects of the sun, shade and nourish the trunk. Bark on younger trees can be protected in this way and the damage in the right pane (Figure 11) can be avoided or reduced to a considerable degree.

The temporary branches can be reduced as the young tree develops and the trunk becomes more supportive.

Removal of water sprouts

Figure 12: Removal of young upright branches (water sprouts)

Occasionally a young vigorous branch will grow more upright than others and will compete with the leader. Unless the sector is devoid of other limbs, the upright branch should be removed.

Vertical and radial spacing of scaffold branches

Figure 13: Vertical and radial spacing of scaffold branches

On large-growing trees, the permanent scaffold branches should be well spaced vertically and radially.

Avoid one limb growing directly above another – this interferes in the nourishment of the higher limb, and the higher limb can unduly shade the lower limb.

25

Proper radial distribution of limbs

Figure 14: Proper radial distribution of limbs

Proper radial distribution of limbs will allow limbs adequate space for development.

Obtaining lateral branches

Figure 15: Obtaining lateral branches from vigorous growing young trees with strong apical dominance

Vigorous young trees with strong apical dominance may grow 2 m with no lateral branches forming (D). If the leader is pinched during the growing season when the terminal is 50-100 mm above the height desired for the first scaffold (A), two or more shoots may be encouraged to grow. Select a second one as a lateral and head it lightly if required. Head the others more severely (B). Repeat the process as long as the vigorously growing leader can be selected (C).

26

Upright growth of horizontal branch

Figure 16: Training a horizontal branch to grow upright

In contrast to upright branches, horizontal branches exhibit less vigour. To cause a horizontal branch to grow more upright, prune it back to an upright lateral (C), or cut it back to an upright facing bus (B ), or cut it back near the top of an arch (A) .

Obtaining better symmetry from wind-deformed tree

Figure 17: better symmetry from a wind-deformed tree

In windy sites, the top of the tree can be opened up by removing moderate sized branches. This will reduce the trees wind resistance, and accordingly the stress exhibited on the trunk and limbs.

A tree deformed by the wind can be made more symmetrical if branches on the windward side are headed back to a lateral or a bud pointing into the wind, if the leader is thinned to a more upright lateral, and if some of the downwind branches are shortened.

27

Selection of alternate leaders

Figure 18: the selection of alternate leaders

When a leader has been outgrown by one or more laterals, thin the leader back to one of its most vigorous and upright laterals. This lateral will then become the leader.

Maintenance of leaders by cutting-back

Figure 19: Maintenance of leaders by cutting back

Leaders can be maintained by heading back any laterals that may compete with it (A). Prune these laterals fairly severely if they are temporary (B). The tree will grow taller (C) than if it had not been pruned (D).

28

Removal of low spreading branch

Figure 20: Removal of a low spreading branch

If there is a suitable branch above, completely remove a low spreading branch (red arrow) instead of pruning it back to less drooping laterals. Beware of increasing trunk stress in the process.

Use of lower natural crown to lower tree height

Figure 21: Lowering tree height to lower natural crown

The major advantage of this procedure is that the tree will usually appear unpruned. In some instances the height of the tree can be lowered to below the height of the lower natural crown if there are adequate branches available.

29

Pruning-back for room

Figure 22: Pruning back closely spaced trees in order to create room

Crowded trees can become mishappen and their branches weakened by shading and rubbing. In some instances the smaller, or more deformed, or less desirably located trees should be removed. The remaining trees will grow into the new space with improved health and appearance.

Trees are often planted closer together than will be desirable when they reach mature size. As these trees begin to crowd, the less desirable ones should be pruned back more severely each year until they are removed (B).

This will allow proper development of the more permanent trees while retaining the value of the temporary trees.

Lateral / directional pruning

Figure 23: Lateral / directional pruning in proximity to utility services

Lateral or directional pruning involves pruning the leader back to a lower outward-growing limb (lateral). Examples are given in Figure 23.
