Quick Facts…

  • Trees provide shade, beauty and protection from harsh winter winds.
  • Trees help moderate temperature extremes and offset poor air quality.
  • Plant trees on the basis of space available, soil conditions, proximity to irrigation lines and water requirements.
  • Plant trees prone to storm breakage away from buildings, walks, and driveways.

Everyone enjoys the beauty a shade tree provides. Trees also reduce harsh winds, moderate temperature extremes, and offset poor air quality.

How to Select a Tree

To select a tree, consider the following factors.

Available space. The location you choose for each tree should have enough space to allow for growth without severe pruning. Check for obstructions of buildings, overhead utility lines and tall fences. If lateral space is limited, select a tree that has a narrow, upright growth habit. Refer to height, branch spread and shape in the tree list shown in Table 1. If overhead lines are near, you may want to choose small trees. (See fact sheet 7.418, Small Deciduous Trees.)

Soil conditions. Most trees perform best in well-drained soil. Dig a saucer-shaped hole that is 2 to 3 times the width of the ball. Remove soil from the top of the root ball to expose the root flare if not visible. When planting, make sure first root is at or one to two inches above grade.

Irrigation lines. If you have an underground irrigation system, plant trees to allow for the tree trunk and basal root flare to expand without encroaching on an irrigation pipe. Otherwise, tree roots may eventually compress the pipe and shut off the irrigation line.

Growth rates vs. brittleness. As a general rule, fast-growing trees tend to be brittle and can be damaged by limb breakage in storms. Plant these trees away from buildings, sidewalks, driveways and utility lines.

Water requirements. Trees vary in water requirements. Do not plant trees that have low water needs in heavily irrigated lawn areas or at the bottom of slopes. Plant trees with high water requirements in locations where supplemental watering is possible and desired. In dry years, fall and winter watering is critical to the health of trees. Trees under drought stress are more susceptible to insect and diseases. For details, see 7.211, Fall and Winter Watering.

Large Trees for Shade

Table 1 includes trees that will exceed 30 feet in height when fully grown. These trees should not be placed under or near power lines or other overhead structures. Use one-half of branch spread (diameter) indicated below to determine minimum distance from structures. Greater distance from structures may be desirable.

Description of Tree Shapes

The following tree shapes describe the general outline of the trees in the accompanying tree list. Use this chart in combination with height and branch spread to determine proper location of trees and ensure adequate clearance from obstacles.

columnar shape Figure 1: Columnar. Sides more or less parallel, much more tall than broad. conical shape Figure 4: Conical. Cone-shaped. Broad at base, tapering to a narrow top. upright spreading shape Figure 6: Upright spreading. A narrow vase shape.
weeping shape Figure 2. Weeping. Branches tend to weep downward. broad spreading shape Figure 5: Broad spreading. A wide vase shape. elliptical shape Figure 7: Elliptical. More tall than broad, widest branching at or near the middle.
round or globe shape Figure 3: Round or globe. About as broad as tall.
