Pruning Trees
• Why do we prune
trees?
• For the tree’s health
• For flowers, foliage,
fruit, and stems
• For a pleasing shape
and size
• For safety
Tools Used in Pruning
Care of Pruning Tools and Equipment
• Provides users with more effective pruning
• Extends the life of the tool
1. Wipe blades after each use
2. Clean periodically with soap
and water
3. Sanitize or disinfect if tools come
in contact with diseased wood
4. Keep tools sharp
5. Oil tools often
6. Know how to properly use the tool
7. Use extra caution around utility lines
Deciduous Trees and Shrubs Pruning Schedule
• Have an active growth season in spring and
sometimes summer
• Drop leaves in autumn
• Spring-flowering
• Summer-flowering
• Shade
• Fruit
• The best time to prune depends on the plant’s
growth and when it flowers
Evergreen Trees and Shrubs Pruning Schedule
• Evergreens do not shed leaves like
deciduous plants
• No obvious dormant season
• Pruning in winter months reduces
sap and resin flow
• Broadleaf Evergreens: Prune
before new growth in the spring
• Narrowleaf Evergreens (conifers):
• Needleleaf: Prune only when the
tan candle is present
• Scale-leaf: Prune before new
growth in the spring
Tree Structure
Pruning Specific Parts of a Tree
• Areas for removal:
• Dead, diseased, or
injured parts
• Suckers and limbs that
rub together
• Branches growing in the
center
• Parallel branches
• Drooping branches
Pruning Cuts
• Three basic cuts for pruning trees:
• Drop-crotch
• Thinning
• Heading
Transplanting Stock
• Ball-and-burlap
• Bare-root
• Container
• Rooted cuttings
• Seedlings
• In Oklahoma, trees are
commonly planted during
their dormant stage:
• Early December to March
Transplanting Trees and Shrubs
• Planting Preparations
• Prepare the soil
• Choose transplanted stock carefully
• Plant trees and shrubs at correct depth
• Care of transplanted Trees and Shrubs
• Water plants regularly
• Supplement with fertilizer
if needed
• Prune young trees
Mulching
• The spreading of mulch over the soil
• Recommended when planting outdoors to reduce
maintenance and promote healthy plant growth
• Conserves moisture by
reducing evaporation
• Reduces compacting of a soil
• Helps soil maintain a
constant temperature
• Can be either organic or inorganic
