Trees are generally available from the nursery in one of the four forms:
|
"bare root
containerized container grown balled and burlaped" |
|
Bare-root trees are normally planted when (blank), before buds begin to grow.
|
dormant
|
|
(blank) roots can become a problem because they can constrict the vascular system in the trunk or in other roots.
|
Girdling
|
|
Planting holes should be dug (blank) to (blank) times the width of the root ball at the surface, with the sides sloping down to the diameter at the base of the root ball.
|
2 to 3
|
|
Trees that are dug in the nursery are often wrapped with (blank) to help keep the root ball intact and reduce exposure of the roots to air.
|
Burlap
|
|
The planting hole should never be (blank) than the root ball.
|
Deeper
|
|
in areas where the soil is heavy clay, plant trees with the rootball (blank) to (blank) inches ((blank) to (blank)cm) higher than the original grade.
|
"2 to 3
5 to 8" |
|
true/false-- research has shown that soil amendments generally do not assist the tree in establishment and growth.
|
TRUE
|
|
true/false-- digging a tree for transplanting can remove as much as 90 percent of the absorbing roots
|
TRUE
|
|
in temperate climates, the two best times to transplant most trees are (blank)(blank) and (blank).
|
early spring and fall
|
|
when transplanting a tree, the root ball should be (blank) to (blank) inches ((blank) to (blank)cm) diameter for every inch (centimeter) of tree caliper. in general, a root ball depth of (blank) to (blank) feet ((blank) to (blank)m) should be sufficient.
|
"10 to 12
25 to 30 2.5 to 3 .7 to.9" |
|
true/false-- if trees have wire baskets to help maintain the integrity of the root ball, these baskets should never be removed nor should the top portion be cut off at planting.
|
FALSE
|
|
true/false-- most of the new roots generated after planting will grow horizontally and near the soil surface.
|
TRUE
|
|
"Pre-digging to create a more densely rooted ball es called (blank)(blank).
|
Root Pruning
|
|
true/false-- staking of newly planted trees is not always necessary.
|
TRUE
|
|
"Name three adverse effects of staking or guying trees.
|
"a. wounding of trunk or branches
b. girdling if left in place too long c. less stable root development d. un even trunk wood and taper development" |
|
"true/false-- the material used to attach the tree to the stake should be broad, smooth, and flexible.
|
TRUE
|
|
warm soil temperatures and adequate soil (blank) are the optimal conditions for new root growth.
|
moisture
|
|
true/false-- in general, palms are easy to transplant
|
TRUE
|
|
when transplanting palms, the fronds are often tied up to protect the solitary (blank).
|
bud
|
|
Transplant shock is mainly due to (blank) stress from the greatly reduced root system.
|
water
|
|
if fertilizer is applied at planting, it should be a (blank)-(blank) release type to avoid excess salt build up in the root zone.
|
slow-release
|
|
True/false-- there is no advantage to pruning one-third of the tree crown at the time of planting
|
TRUE
|
|
the most important maintenance factor in survival of a newly planted tree is proper (blank)
|
irrigation/watering
|
|
true/false-- tree roots may suffocate if the tree receives too much water after planting.
|
TRUE
|
|
What are the advantages and disadvantages to planting each of the following ways:bare root, balled and bur-lapped and container grown?
|
"bare root- a. no girdled d. root rot
balled and burlapped- a. blank d. blank container grown- a easy handle d. girdled" |
|
why is the use of soil amendments in the back fill of planting holes no longer recommended
|
immediate change in soil texture and ph stresses the plant out
|
|
what are some of the special considerations of transplanting palms?
|
weak trunk & thin trunk
|
|
pruning of one-third of a trees crown to compensate for root loss when transplanting has not proven to be beneficial. why might this be the case?
|
photosynthesis is reduced, reducing root growth
|
|
staking or gying when planting a tree is
a. done only for bare- root trees b. not necessary for trees greater than 6 inches (15cm) diameter c. not always required or necessary d. for promoting a larger and stronger root system and better trunk taper |
not always required or necessary
|
|
planting a row of palms at barious depths to create a row of uniform height
a. will not be harmful as long as the soil is sandy and well drained b. can lead to death of the deeply plant trees c. is acceptable due to the deep rooting of palms d. is recommended to achieve deep rooting in sandy soils |
can lead to death of the deeply plant trees
|
|
placing gravel in the bottom of planting hole in a clay soil site will
a. improve drainage b. prevent formation of girdling roots c. restrict soil space and create a perched water table d. improve aeration and water infiltration |
restrict soil space and create a perched water table
|
|
when planting a container -grown tree,
a. separate and tease apart the roots to reduce girdling root formation b. place soft fill in the bottom of the planting hole to encourage tap root growth c. back fill the hole with soilless growth medium to encourage root growth d. none of the above |
separate and tease apart the roots to reduce girdling root formation
|
|
the most important reason to prune a tree when transplanting is to
a. compensate for root loss b. invigorate the tree c. reduce growth at the tips d. remove structurally weak or damaged branches |
remove structurally weak or damaged branches
