Question 3

A ____ _____ is a process used to achieve the desired long-term form of a plant

Answer 3

Pruning system

Question 4

A ____ _____ system is performed with an understanding of a the tree’s natural characteristics and growth patterns, while allowing for changes in appearance. Most utility pruning falls under this system

Answer 6

Topping (roundover)

Question 7

A ____ ____ ____ is made when removing the smaller of two branches at a union, without cutting into the branch bark ridge or branch collar, or leaving a stub

Answer 7

Branch removal cut

Question 8

A ____ ____ removes the larger of two branches, or codominant stem, at a union, to a live lateral branch at least 1/3 the diameter of the stem/branch being removed. Should be done at a slight angle

Answer 8

Reduction cut

Question 9

A ___ _____ removes a branch or leader either between nodes, or to a much smaller lateral branch, or to a bud. Cutting an older branch or stem back to a stub in order to meet a structural objecting

Answer 9

Heading Cut

Question 10

Slightly enlarged growth point on a stem where leaves and buds arise

Answer 10

Node
