CODIT
Inhibits decay in a vertical direction. this is the weakest wall. Produced by gums and resins
Wall 1
Used to develop desired branch and canopy structure. Exs: structure pruning, clearance, deadwooding
Natural Pruning
Another name for epicormic growth
Suckers
Diameter of a branch in relation to parent branch or stem
Branch aspect ratio
3 reasons why we prune
Safety, health, aesthetics
Inhibits the movement of decay towards the central core of the stem. created by latewood cells
Wall 2
Used to maintain trees at a desired height. Species, size, and age dependent.
Pollarding
The reason why trees produce epicormic growth
Stress, overpruning, drought
The ratio at which likelihood of failure dramatically increases
50%
Benefits of Pruning
Increased fruit production, reduced risks, promote better tree health/ life expectancy, maintain aesthetics, curb appeal
Made up of ray cells. these cells inhibit the movement of decay RADIALLY, around the stem. this is the strongest wall.
Wall 3
Espalier
The phase in a tree's life when we want to do the heavier pruning
Juvenile/adolescence
Can slow the growth of a competing stem
Reduction pruning
maximum that can be pruned from a tree without causing irrecoverable damage
30%
New protective wall created by cambium layer. This creates a Barrier Zone. this is the STRONGEST wall
Wall 4
Used to maintain trees or shrubs in desired/uniform shape
Topiary
Trees don't heal, they ____
This is most common in branches with aspect ratios of 50-90%
Bark inclusion
when pruning, the ability of the tree to ___________ becomes reduced
Photosynthesize
4
how many walls are there in CODIT?
Combining pruning and branch training to create archways or allees
Pleaching
The ratio of the height of the lowest limb to the height of the total tree height
live crown ratio
