Presentation Transcript

Terms l.jpg

  • pruning - removal of parts of the top or root systems of plants

  • fruit spur - stubby, fruit bearing twig

Terms3 l.jpg

  • translocation - movement of water and soluble minerals from one part of the plant to another

Terms4 l.jpg

  • inhibit - prohibit or slow action

  • hormones - chemical compounds produced by plant. Regulate plant functions

Terms5 l.jpg

  • twig - very small branch of a tree

  • cane - stem of various fruits. Ex: raspberry

Terms6 l.jpg

  • shoot - small outgrowth on a bush

Facts l.jpg

  • generally has no specific season

  • continuous process

  • serves a purpose for the plant

Facts8 l.jpg

  • enhances ornamental value

  • generally prune with natural form of the plant, not against it

Purposes l.jpg

  • remove diseased, dead, or damaged limbs

  • restrict or promote growth

  • develop certain forms of growth

Methods of pruning l.jpg
Methods of pruning

  • root

  • shoot or stem

Stem pruning l.jpg
Stem pruning

  • reduces amount of growth

  • influences vegetative reproductive balance of the plant

  • reduces plant size, yield, and total amount of growth

Stem pruning12 l.jpg
Stem pruning

  • Increases supply of essential elements to the points of growth that remain

Stem pruning13 l.jpg
Stem pruning

  • promotes the making of cells and the utilization of carbohydrates

  • stimulates vegetative phase, retards reproductive phase

Root pruning l.jpg
Root pruning

  • affects total amount of growth made

  • reduces amount of available essential elements - causes dwarfing

Root pruning15 l.jpg
Root pruning

  • influences vegetative reproductive balance of plant

  • promotes root growth

Root pruning16 l.jpg
Root pruning

  • favors reproduction, retards vegetative phase

  • used to prepare plants for transplanting

Top pruning l.jpg
Top Pruning

  • heading back

  • thinning out

Heading back l.jpg
Heading back

  • terminal - top portion is removed

  • stimulates development of more points of growth

Heading back19 l.jpg
Heading back

  • induces compact, dense, or branched type of growth

  • removes hormones that inhibit branching

Thinning out l.jpg
Thinning out

  • entire twig, cane, or shoot is removed

  • does not prevent development of lateral buds

  • induces open type of growth

General rules l.jpg
General rules

  • use correct tools for the job

  • prune back to existing bud or to a side branch

  • never leave a stub!!!!!!!!!!

General rules22 l.jpg
General rules

  • cut larger limbs in three steps

  • draw the illustration on the board silly teacher! :)

General rules23 l.jpg
General Rules

  • pruning in summer results in greater dwarfing than pruning in late winter months

General rules24 l.jpg
General Rules

  • buy and plant trees and shrubs that have the characteristics and shape that you want

Pruning tools l.jpg
Pruning tools

  • thumb and forefinger

  • pinch off shoots

  • pinch off unwanted buds, long stems, and fruit spurs

  • snap off faded blooms or seed pods

Edgers l.jpg

  • enable user to stand and cut the edges of lawns

  • also used on ground covers

Grass shear l.jpg
Grass Shear

  • used to cut grass around sidewalks, driveways and planting beds

Lopping shears l.jpg
Lopping Shears

  • use when added leverage is needed

  • used for reaching into trees

  • small branches or twigs

Pruning shears l.jpg
Pruning Shears

  • many types

Hedge shears l.jpg
Hedge Shears

  • hand operated

  • electric or gas powered

Pruning saws l.jpg
Pruning Saws

  • cut quickly

  • useful in overhead work

  • straight or curved

Pole pruners saws l.jpg
Pole Pruners & Saws

  • used to cut or saw branches high overhead

  • telescoping - go up to 18 feet

How and when l.jpg
How and When

  • Deciduous Shade Trees

  • when - dormant - early spring before leafing out

  • exception - bleeder trees - Mid June

Bleeder trees l.jpg
Bleeder trees

  • Sugar Maple

What to look for l.jpg
What to look for

  • Central Leader - single leader

  • multiple leaders - narrow crotch angles in time will break

What to look for36 l.jpg
What to Look for

  • scaffold branches

  • crotch angle 45-90 degrees

  • limbs spirally arranged

  • prune off lower limbs 8-10 feet high

What to look for37 l.jpg
What to Look for

  • distance vertically between scaffold branches

  • lowest branch on SW side

  • remove suckers - weak wood

  • remove hangers

What to look for38 l.jpg
What to Look for

  • remove water sprouts

  • remove parts growing in toward center of trees

Fruit tree pruning l.jpg
Fruit Tree Pruning

  • spurs - majority of fruit production is borne on spurs

  • open tree up to let light into spurs

  • spurs bear fruit every other year

Evergreens l.jpg

  • don’t respond well to pruning

  • broadleaf - like deciduous flowering shrubs

Evergreens41 l.jpg

  • needle types - pines, spruce, fir, juniper, yews, respond better

  • spruce or fir - single needle prune back to 1/4 inch above axillary bud

Junipers yews l.jpg
Junipers & Yews

  • awl shaped needles

  • prune spring to mid summer

  • when temperature is above freezing

Slide43 l.jpg

  • candle growth - new growth from tip of branches, milky green color

  • remove 1/3 to 1/2 of candle growth in the spring

Deciduous shrubs l.jpg
Deciduous shrubs

  • spring flowering - lilac, honeysuckle

  • set flower buds during previous year

  • prune after flowering

Summer flowering l.jpg
Summer flowering

  • roses, hydrangia

  • set flower buds same year that they flower in spring

  • prune before bud set

Deciduous shrubs46 l.jpg
Deciduous shrubs

  • avoid August and September pruning for all deciduous material
