A line of rough bark running from branch-trunk crotch into the trunk bark.
Swollen area of tissue that forms around the base of a branch.

Pruning back laterals that have grown taller than terminal leader.
Growth resulting at season’s end from pruning vigorous laterals.

New Spring growth on spruce branch.
Pinch back new growth 50% on spruce and other
whorled conifers.

Topping
• Removes tree canopy– Resulting in limited tree food making and the loss of stored food
reserves
• Removed leaves exposes bark to direct sun rays– Resulting in scalding & even death to the tissue
• Removes existing buds that produce normal branches• Removes terminal buds that produce root inducing
hormones– Results in reducing a trees ability to form new nutrient and
moisture absorbing roots

Topping
• Large stubs seldom seal properly– Resulting in vulnerable to decay fungi and insects
• Stimulates dense, bush-like water sprouts– Resulting in structurally weak growth susceptible to wind and ice
damage.
• Topping disfigures trees– Looks ugly and unnatural
