1. What do you want the tree to do? (Pick one or more.)
Focal point for your landscape
Roots can extend two to three times beyond the canopy,
although, with most trees, the roots with the greatest potential
to cause damage are generally found within the area under the
2. How much space does the tree have to grow? Are
there any obstacles overhead, to the side, at ground level, or
No power lines overhead
If you are planting near power distribution lines that run through
residential areas, the most important thing to remember is the
30-FOOT RULE: Trees and plants within 30 feet of power lines should
not grow higher than 30 feet tall when fully grown. Consult your
nursery or landscape professional for trees whose mature height
does not exceed 30 feet.
No buildings in close proximity
Don’t plant trees that can grow large enough to contact buildings
or block signs. Trees that grow over roofs and rain gutters can create
maintenance problems and damage buildings.
No underground utilities
Do not dig or plant until you identify all nearby underground utility
lines, including cable, sewer, and power lines.
Do not plant trees
on top of underground lines.
Do not plant trees with aggressive roots
near underground utilities where their roots can damage the facilities.
No swimming pools near site
If trees will be near a pool, select trees that do not drop leaves
that will fall or blow into the pool.
No plants or other landscape features that may suffer in the shade
of a large tree
Ensure that large trees will not grow over and shade out smaller
trees, shrubs, and groundcovers.
No obstruction of scenic views
Ensure that the tree will not grow to block a desirable view for
you or your neighbors.
No nearby driveways/roadways/sidewalks
Select trees that have a high, clear trunk or that can be practically
pruned so as not to obstruct safe travel.
Do not plant large trees
near driveways, roadways, curbs, and sidewalks where their roots
may cause damage.
No nearby walls
Do not plant large trees near walls. Their roots may cause damage
No nearby property
Do not plant trees where roots can invade and damage neighboring
It’s important to identify and avoid any obstacles that could
restrict the canopy and root growth of your tree, or could be damaged
by any part of your tree. Also, identify any situation where your
tree could create a safety hazard or nuisance.
Tree shade is better than Venetian blinds, plastic coatings,
or reflective glass surfaces at cooling your home on hot, sunny
days. Shading walls and windows can reduce air conditioning
energy costs by 30 percent or more.
If obstacles are near the site, how far away from the planting site
are they? They must be far enough so that the top, canopy, or roots
of the tree do not interfere with these obstacles when the tree is
at its mature size and maximum growth range. It’s important
to note that roots can extend two to three times beyond the canopy.
With most trees, however, the roots with the greatest potential to
cause damage are generally found within the area under the canopy.
3. How are the planting conditions at the
Select a tree that will thrive or at least tolerate the growing
conditions of the planned site.
Quality of sunlight
Is there sufficient sunlight to ensure proper growth?
-Direct all day
-Filtered through overhead obstacles
Sufficient natural water
Natural availability of water may limit the selection of trees suitable
for the site, without artificial irrigation.
Quality of soil
The type of soil on site may limit your selection of plants to tolerant
Depth of the soil
Make sure the soil is deep enough to support the tree’s root
system. Most of the tree’s roots are confined to the top two
feet of the soil layer. A large tree may be inappropriate for shallow
or unstable soil.
Exposure to salt spray
If the planting site is near the beach, make certain that the tree
you select is salt tolerant.
Usual strong winds
If the site is windy, are the trees sensitive to or damaged by strong
4. Will the tree grow well in your neighborhood?
One easy way to answer this question is to take a look around your
neighborhood. See how others have used trees in their landscaping
design and find out what kinds of trees are growing well. Your local
plant nursery can also suggest appropriate trees for your climate
and soil conditions.
5. How much maintenance does the tree require?
-Is the tree low maintenance?
-Does the tree drop lots of leaves and/or fruit?
-What kind of maintenance can you reasonably provide?
If cleanup is a concern, don’t plant trees that are deciduous
