Pruning Terms Video
oBud
A bud is an unexpanded shoot or flower. Buds occur at nodes singly or in
pairs and may be terminal (at the apex or tip of a shoot) or lateral (axillary
means in a leaf axil).
Terminal bud – at end of stem; lateral buds are all along the stem.
oTrunk
The main lower stem of a tree, usually covered with bark
oCrown
System of living branches and stems of a tree that are supported by the
trunk
oCanopy
Foliage; the sum of all the leaves and small twigs of a tree that are
supported by the crown
oCentral Leader
Single stem of a tree that runs vertically from the ground to the top of the
tree; 2:32
oScaffold or Support Branches
Attached to the central leader and structurally provide the main support for
all foliage
oExcurrent growth form
Trees with a dominant single central leader
oDecurrent growth form
Trees or shrubs with many leaders, none dominant
oColumnar growth form
Palms with a single leader with one terminal growing point
oPollarding
A pruning system in which the upper branches of a tree are removed to
promote the regrowth of a dense head of foliage and branches. Pollarding
has been common in Great Britain and Europe since medieval times. Trees
traditionally pollarded to either provide leafy digestible fodder for
livestock or to give kindling wood for fires; not useful today.
oTopping
Trees pruning in which the tree is headed back to lower the height of it;
power companies do this.
oPruning Practices that harm trees
Topping trees should NEVER be viewed as a normative or best practice
oShearing
Frequent removal of small amounts of foliar tissue or leaves
oNATURAL IS HEALTHY AND BEST
oTopiary
Special pruning practice, intensive, to create a specific shrub or tree,
various shapes, canopies and even animals.
oEspalier
The practice of controlling woody plant growth by pruning and possibly
grafting branches so that they grow in relatively flat planes, frequently in
formal patterns, against a structure such as a wall, fence, or trellis.
Pruning Tools Video
oHow to select the right tool for the right job…
Select and use the proper pruning tool is based on the stem or branch
caliper. Tool blades MUST be sharp.
Note: Use of all pruning equipment requires special training, safety
precautions, and safety gear.
oHand held pruners “snips”
If stem caliper is less than 3/8”, then use hand snips
3 kinds
oGrape and houseplant snips
oBypass snips
oAnvil snips
oLoopers
If stem caliper is less than 1”, then use loppers
Fiberglass or tubular steel handle loopers, or wood handle loopers
2 kinds (above)
oManual and Power Hedge Shears
Manual shears are like normal clippers
Power Hedge shears are like a electric saw
oShearing is used for the fast removal of fleshy stems with stem caliper less than
3/8” in order to create a formal plant appearance
oSaws
If stem caliper is greater than 1”, use a saw
If stem caliper is between 1-3”, use hand saw
If stem caliper is greater than 3”, use a power saw
Pruning Techniques Video
oHeading cut
Partial removal of a stem or branch
oThinning cut
Entire removal of a stem or branch
oInformal pruning technique; 1:44
Heading cuts, but the key is to not make heading cuts all the same length
but at various depths; staggered layers of cuts
Results in informal appearance
