25
Define soil compaction
When air is driven from the soil and water is unable to freely enter the root system (you get a hard pan formation and the nutrients won't go down without air or water)
26
What is a tool that uses an air compressor to send a high volume of air into the soil in a way that breaks up compacted soil without injuring the root structure?
Air spade
27
What is occurring when 12 inch holes are drilled and filled with course mixture, permitting water and air to enter?
Vertical mulching
28
Why does mulch need to be replaced?
To prevent germination of weeds, decomposition, and plant death
29
What is radial trenching and what is it used for?
- when narrow slits are cut in a spoke pattern around the tree (critical root zone and filled with topsoil or compost) - used for isolated lawn trees
30
What does edging refer to?
Cutting a sharp line of separation, usually between a planting and adjacent lawn
31
What does the act of edging use and what will it help reduce?
- uses an edging tool or flat-back spade to cut into the ground 6-8 inches and remove the wedge of sod - the sloped cut will reduce root competition and improve the soil, and retain a sharp turfline
32
____ is the removal of a portion of a plant to improve its appearance and health to control its growth and shape
pruning
33
____ are used to cut branches up to 1/4 inch in diameter
Hand pruners

____ are used to cut branches up to about 1/2 inch and have handles longer than hand pruners
Lopper pruners
35
____ is the most task-specific of all pruning tools and are used to shear and shape hedges. They are available as a scissor-like hand tool or as a wand-like power tool
Hedge shears
36
____ is used when a branch exceeds 1/2 inch in diameter
Hand pruning saw
37
What permits you to reach the upper part of the tree and you need to be cautious not to cut until you are certain of what is being severed?

the canopy, or the foliage of the tree
41
Define crotch
the point at which a branch meets the trunk of the tree or another large branch (kind of a joint)
42
Branches that originate from the underground root system are called
Suckers
43
____ ____ are the branches that develop along the trunk and branches of a tree (the latent/dormant buds that are waiting for the right circumstances to come, and sprout when those conditions arise)
Water sprouts
44
In shrubs, the best flower and fruit production are on the _____
younger branches
45
What differs younger branches of a shrub from the older branches?
- usually lighter in color | - thinner bark and in diameter
46
Define crown
the point at which branches and the root system meet
47
____ are prostate stems that are new shoots arising from existing roots (a long/thin stem that usually grows horizontally along the ground and produces roots and shoots at widely spaced nodes) What's an example?
- Stolons | - ex. strawberries
48
Define stock
- the root portion | - anything underground, anything keeping the root portion
49
_____ is if you want to grow a tree in an area where it's not an option and then put it on something that is close to the species that you want
Grafting
50
What is a benefit of winter pruning?
It's unblocked by foliage
51
What is a benefit of summer pruning?

When are center shoots shortened or removed from plants?
When the purpose is to create denser foliage

the younger branch
58
_____ is when the scaffold limb is removed without taking a long slice of bark with it when it falls and covering the wound with wood paint until it heals

59
What is the procedure of jump-cutting?

60
_____ is the removal of a shrub branch at or near the crown, or its point of origin
Thinning out
61
What is the shorteninf, rather than the total removal of a twig, and what does it encourage?
- Heading back | - encourages lateral growth

Define complete/gradual renewal
removing all mature wood over a 3-5 year period (gradual), or completely removing all stems to ground level (complete)
63
How should twigs be pruned?
To leave an outward pointing bud
64
What are the main focal points of a landscape and require lots of care?
Flower plantings
65
Flowering plants require more maintenance because of what?
- weeding - insects and disease - saggy if not pinched back - one-time blooms - bulbs need to be dug up
66
_____ lose their effectiveness if the soil is disturbed after application

67
Shallow roots, shaded areas and ____ may need to be watered daily to prevent wilting
plants in containers
68
When should annuals be fertilized?

69
When should bulbs be fertilized?
immediately after flowering (because the bulb has something for the shoots)
70
When should non-bulbous perennials be fertilized?
early spring (to enhance growth)
71
Define dead-heading
When dead flower blossoms must be continually removed
72
What is done with the thumb and forefinger right at the top of the stem?
