Deadheading by snapping out the faded flower trusses.

One year after deadheading.

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

36

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
