14 Optimum attachment of scaffold branches

15 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. Conifer

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

35 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
