nursery/landscape 22-26 set 5

Trees are fertilized with granular fertilized with granular fertilizer by spreading it within

• a four foot radius next to the trunk

• area covering the outer two-thirds of the distance between the trunk and the drip line at least 50% of the crown radius beyond drip line

• only within the distance of from the trunk to the drip line

• a thirty-foot radius from the trunk

landscape plans are generally included all of the following except

• a north orientation marker

• the number of each type of plant to be planted

• the mature height of the plant

• the mature with of the plant

which I most important to the financial health of a nursery/landscape business?

• net profit

• cost margin

• margin cost

• gross sales

an area of the landscape that includes spaces for such items as a clothesline and garbage cans is the area:

• service

• private

• public

• recreational

the optimum germination temperature for most bedding plant seeds is

• 60 to 65

• 75-85

• 50-55

• 65-75

Some seeds are produced in the fall and remain on or in the ground until they germinate in the spring. Exposing roots to the winter cold and moist soil is nature's method of----- the seed

• Acidifying

• sporulating

• stratifying

• scarifying

if a container-grown nursery crop has been over-watered for a long period, a grower might expect to find the roots in the following condition:

• the roots may be extra thick and bright white in color

• the roots growing though the drain holes in the bottom of the container

• the roots are dead or absent at the bottom of the container but healthier in the top portion of the container

• the roots are dead or absent at the top of the container but healthier in the bottom of the container

one reason modern horticulture fabrics used in landscaping are said to be better than black polyethylene film is they

• allow exchange of gases between soil and air

• completely control weeds

• prevent moisture from penetrating to deeply

• makes a better base for rock mulch

when alan finished sharping his rotary mower vibrated and shook so badly that he could hardly control it

• the spark plug was loose

• the blade was out of balance

• the blade had been over heated, effecting its temperament

• the blade was made from inferior metal

plants usually do not grow well in poorly drained soils because:

• plant roots become engorged with water in poorly drained soils

• poorly drained soils warm too quickly In spring

• the organic matter content of poorly drained soils is too high

• oxygen content is low in poorly drained soils
