
FRUITING HABIT
Prune weak growth hard and strong
growth light. Hard pruning lessens the
amount of flower buds being served by
tree and allows for better production from
the remaining bugs.
Heavy crops produce small
unsatisfactory fruits /
biennial bearing
Blossom thinning
BALANCE
Younger wood produces
finer fruit
10 days after blossom pinch out 9 of
every 10 blossoms

Apple & pear on 2 year wood
Sour cherry, peach & nectarine on

Plum, sweet cherry & apricot on 2 year
and older
Fruit thinning

ROOT
Best done on young trees in winter.
Lift, prune and replant.
Large trees done over 2 year span .
Stake after pruning.

CANKER - Generally affects apples.

CROWDED OR CROSSING - Touching branches
Heavily cankered trees
should be discarded. Cut tree below infected area where healthy
tissue resumes. Disinfect tools.
lead to bark/insect damage. Overcrowding creates stagnant air,
poor circulation.

BROKEN – Cut branches or exposed bark are susceptible to
water penetration.

TRAINED FORMS - Reduce growth and thin congested
spurs. Try to regain form, if not feasible, replace tree.
NEVER TAKE OFF MORE THAN ¼ OF TREE.

SPUR PRUNING - Shorten laterals to
increase fruiting side shoots. Continual spur
pruning eventually leads to congestion.
Pushes production closer to main branches.

THINNING – Pruning out spurs that
have become congested or overcrowded.
oTIP
PRUNING – Cut older shoots back to 1 or
2 buds. Remove shoots after 2 years of
fruiting.

SUMMER PRUNING – Formally trained
trees. Cordons, espalier and fan tree
forms. Used to restrict growth and
encourage fruiting bud formation.

AKA – The Lorette System Where all shoots, 6-9 inches are
pruned to 2 inch length. Creating a
woody base. Pruning is continued
throughout summer on shoots
stimulated from 1st round of pruning.
Also used to discourage secondary
growth.

Pruning in winter makes tree
susceptible to silver leaf
disease.
Prune for training at bud
burst in spring for new trees
and summer for established
trees.
Prune out diseased, dying or
dead wood immediately.
Remove shoots with narrow
forks or V angles.
Fruit thinning rarely needed.

Easier to grow in colder
climates.
