Balled & Burlapped

Bare Root

Container Grown

Containerized

In what four forms are trees are generally available from the nurseries?

Dormant

Bare-root trees are normally planted when _______, before buds begin to grow.

Girdling

_______ roots can become a problem because they can constrict the vascular system in the trunk or in other roots.

2, 3

Planting holes should be dug ___ to ___ 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.

Burlap

Trees that are dug in the nursery are often wrapped with _______ to help keep the root ball intact & reduce exposure of roots to air.

Deeper

The planting hole should never be _______ than the root ball.

2, 3 (5, 8)

In areas where the soil is heavy clay, plant trees with the root ball ___ to ___ inches (___ to ___ cm) higher than the original grade.

True

True/False - Research has shown that soil amendments generally do not assist the tree in establishment & growth.

True

True/False - Digging a tree for transplanting can remove as much as 90 percent of the absorbing roots.

Early Spring, Fall

In temperate climates, the two best times to transplant most trees are _______ _______ & _______.

10 to 12 inches (25 - 30 cm), 2.5 to 3 feet (0.8 to 0.9 m)

When transplanting a tree, the root ball should be ___ to ___ inches (___ to ___ cm) diameter for every inch (cm) of tree caliper. In general, a root ball depth of ___ to ___ feet (___ to ___ m) should be sufficient.

False

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.

True

True/False - Most of the new roots generated after planting will grow horizontally & near the soil surface.

Root Pruning

Pre-digging to create a more densely rooted ball is called _______ _______.

True

True/False - Staking of newly planted trees is not always necessary.

Wounding of Trunk or Branches

Girdling (if left in place too long)

Less Stable Root Development

Uneven trunk wood & Taper Development

Name three adverse effects of staking or guying trees.

True

True/False - The material used to attach the tree to the stake should be broad, smooth & flexible.

Moisture

Warm soil temperatures & adequate soil _______ are optimal conditions for new root growth.

True

True/False - In general, palms are easy to transplant.

Bud

When transplanting palms, the fronds are often tied up to protect the solitary _______.

Water

Transplant shock is mainly due to _______ stress from the greatly reduced root system.

Slow-Release

If fertilizer is applied at planting, it should be a _______ - _______ type to avoid excess salt buildup in the root zone.

True

True/False - There is not advantage to pruning on-third of the tree crown at the time of planting.

Watering

The most important maintenance factor in the survival of a newly planted tree is proper _______.

True

True/False - Tree roots may suffocate if the tree receives too much water after planting.

C

Staking or guying when planting a tree is:

a.) done only for bare-root trees


b.) not necessary for trees greater than 6 inches (15 cm) in diameter


c.) not always required or necessary


d.) for promoting a larger & stronger root system & better trunk taper.


B

Planting a row of palms at various depths to create a row of uniform height:

a.) will not be harmful as long as the soil is sandy & well drained.


b.) can lead to death of the deeply planted trees.


c.) is acceptable due to the deep rooting of palms.


d.) is recommended to achieve deep rooting in sandy soils.




C

Placing gravel in the bottom of the planting hole in a clay soil site will

a.) improve drainage


b.) prevent the formation of girdling roots


c.) restrict soil space & create a perched water table


d.) improve aeration & water infiltration


A

When planting a container-grown tree:

a.) separate & 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.) backfill the hole with a soilless growth medium to encourage root growth.


d.) none of the above


D

The most important reason to prune a tree when transplanting it to:


a.) compensate for root loss


b.) invigorate the tree


c.) reduce growth at the tips


d.) remove structurally weak or damaged branches
