1

average life of downtown/city/rural tree

7, 32, 150

2

where is the terminal and lateral bud

terminal- top
lateral- below top

3

what hormone is in the terminal bud and what does it control

auxin and it controls growth of lower lateral buds

4

if you remove the terminal bud what happens?

releases buds at or below the cut resulting in multiple sprouts

5

what does pruning do

control size, trains growth, encourages flowering and fruiting, corrective pruning, maintains health and appearance. safety concerns, rejuvenates old, overgrown plants, specialty (topiary, bonsai etc)

6

when do you corrective prune

if the plant is diseased, dead, dying, damaged, crossed branches, double leaders, waterspouts, suckers, root suckers, narrow crotch angles

7

things to prune with

pruning saw, pole pruners, chainsaw, hedge shears, disinfectant, secateurs

8

heading back pruning

removal of the terminal portion of a shoot back to a larger lateral branch or bud. this reduces height and hides cut
-to do this you prune back the branch to a lateral

9

thinning/renewal

completely remove 1/3 of largest diameter branches back to the base of the plant on a yearly basis. This opens the plant up and allows for new sucker growth

10

rejuvenation

severely cutting back stems of shrubs (used on suckering, fast growing, overgrown or leggy shrubs only)

11

pinching

removal of tips of shoots to allow for lateral branches to break. This increases bushiness of shrub

12

deadheading

spring flowering plants and pruning

bad time to Prune for a lot of plants because they're prone to disease this time of year or are sapping
-although the wound closes quicker
-dont prune until new, expanding growth has hardened off

23

pruning in early-mid summer

-bad time to prune (disease and insects active)
-retards further shoot growth
-good for spring flowering plants (produces flowers on previous seasons, older growth)
-note that is cuts off flower buds on summer flowering plants

24

when to prune early spring flowering plants

early summer

25

when to prune mid spring flowering plants

prune in early summer

26
