 Slide4

Why

pruning

We prune not because

to

get

more fruit

But we prune to

get

fruits

bigger

and of

higher

qualitySlide5

Two

types of pruning

Winter PruningWinter pruning is the regular

pruning

of fruit trees,

only

for

apple and

pear

.

Summer

Pruning

Summer

pruning

could

be

a

correction

and

preperation

for

winter

pruning

.

And

summer

pruning

can

reduce

the

vegetative

growthSlide6

Pruning

goals

To keep the tree young and vital, if

you

prune

you

care for

new fruit

wood

.

This

wood

will

produce

the fruit

for

the

next

years

.

To keep the

airy

shape

of the tree,

so

that

the branches

will

be

lightend

. And

because

the heat and

light

will

reach

the

fruits

.Slide7

Winter

Pruning

Apple and Pear With

winter

pruning

you start to prune away

: -

Competitors

-

Too

steep

branches

-

Abrasive

branches

-

Broken

branches

-

Dead

branches

On

too

steep

branches a tree

loses

his

energy

. Prune

those

branches

away

,

but

spare

at

least

3

or

4 branches

for

the tree to

lose

a bit of

his

energy

.Slide8

In order to

produce fruitSlide9

Fruit

buds and

growth buds

Grow

buds

are

located

on

the

twig

and are

initially

only

for

leaf

. These

growth

buds are

necessary to

ensure

the

growth

of the tree.

Fruit

buds

are

located

on

a short

twig

. At

this

fruit

buds

will

become

first

the

flower

.

Through

pollination

there

will

be

fruit.Slide10

Summer

Pruning

Apple and Pear In the period of end Juli and August

What

to prune

away

- A large

part of the unusable

shoots

It

reduces

vegetative

growth

By

improved

lighting

the tree is

less

sensitive

for

diseases

and

infestations

Better

lighting

allows

for

a

number

of

rasses

for

a

better

color and

flavor

Slide11

Pruning

Plums

Pruning plum trees may

only

take

place between

mid-April and

mid-September

.

Usually

plum

trees

will

be

pruned

after

the

harvest

.

Choose

a warm and dry day

to prune,

so

the

pruning

wounds

can

dry

quickly

.

Plum

trees

can

be

pruned

as

less

a

possible

-

Don’t

prune

away

more dan 1/3

-

By

overdue

of

pruning

try

to

divede

the

pruning

over

three

years

.

-

Try

to prune a

plum

tree as

less

as

possible

-

Saw

rather

a

large

branch

away

instead

of a

bunch

of

little

ones

.Slide12

How

to prune a plum tree

Prune away the problem branches Prune away

the branches

who

are

curved to far

by

an

excess

of fruit

Strong

upright

braches

can

be

bent

downwards

,

so

the hole branche will

get

sunlight

.

If

there

is

too

much

fruit

it

can

be thin out.Slide13

Important business

Don’t

prune plum trees during the winter the will be

extra sensitive

for

galenaPrune

plum trees

only

during

dry

weather

Disinfect

the

pruningtools

after

every

pruned

plum

tree.Slide14

Why

pruning

cherries On pruned cherry trees,

cherries

will

be

larger and

ripen

better

.

Older

trees

will

be

longer

vital

and

give

longer

production

Pruning

can

improve

the

production

Before

pruning

After

pruningSlide15

Pruning

Cherries

Pruning cherries in the youth stadium is almost the

same

as

pruning

of plums

When

cherries

are

older

,

only

the

crown

must

be

lightend

and the

problem

branches must

be

removed

.

Too

steep

branches

can

be

pruned

away

till

15cm

Fast

growing

shoots can

be

pruned

away

till

15cm

Yearly

2 á 3 fruit branches

can

be

pruned

away

till

15cmSlide16

How

to pruneSlide17

How

to prune

Creat smooth pruning wounds, the plant will

heal

the

wounds

faster. And the tree is less

alive

to

intrusion

of

bacteria

and fungi.

After

pruning

a fruit tree clean and

desinfect

the

pruning

tools.

Some

trees are

very

sensitive

for

bacteria

and fungi

Prune

not

to

far

away

form

the

buds

Make

sure

you

always

prune

away

from

the

bud

,

so

you

can

avoid

water

from

the

pruning

wound

on

the

bud

.
