Five Rules for a Healthy, Long-Lived Tree
|
1.
|
Select only native or well-adapted trees for our area which have unblemished single trunks, firm root balls and more branches than clear trunk (i.e. no “lollipop” specimens). See the plant list for specific recommendations.
|
|
|
2.
|
Locate large trees (over 60 feet at
maturity) no closer than 20 feet
from a building; medium trees
(over 30 feet at maturity) no closer
than 15 feet from a building; small
trees (under 30 feet at maturity)
no closer than 10 feet from a
building; and all trees no closer
than 15 feet from a telephone
pole, fire hydrant, or driveway.
|
|
3.
|
Dig a hole, no deeper than the
root ball or container, but at least
twice as wide as the root ball
(preferably 3 to 5 times as wide).Place the root ball in the center
of the hole.
|
|
4.
|
Backfill the planting hole with a mixture of native soil and a small amount (less than 15%) of compost.
|
|
5.
|
Cover the planting area with three inches of mulch in a three foot radius. Do not make a berm (a tall ring) around the trunk and do not push soil or mulch up around the trunk. Both of these common practices can cause rotting at the tree base.
|
 |
Tree Drip Lines
The most active tree roots will be found in the top few inches of soil around the drip line (shown in red) of your tree. Protect the area in this zone during construction activities.
This is the area to target with slow release fertilizer during the fall and with a soaker
hose if irrigation is needed. |
Establishing a New Tree During Drought
A prolonged drought is not the ideal time to plant a new tree. But if you're diligent about watering appropriately, it can be done, and with very little additional water.
Just water your new tree by hand using our 3-2-1 watering plan. Be sure to soak the root ball thoroughly every time you water. But also be careful not to over-water. That can stress a new tree just as much as not watering enough.
