When to plant?
The best time to
plant a tree in our area is right after leaf-drop which occurs sometime
in mid to late November. December and early January are good times,
too.
Why is that?
In
our area, tree roots grow throughout the fall and winter because the
soil doesn’t freeze. A newly planted tree, although dormant above
ground, can develop new roots throughout November, December, January,
February, and March. That’s almost four full months of energy dedicated
almost entirely to root development! Fall-planted trees perform better
than trees planted in spring or summer and have the advantage of a more
developed root system when the warm months arrive.
- Choose a planting location
Consider whether a tree in the chosen location will shade your home or
air conditioning unit, or serve as a buffer for winter winds. Make sure
the tree will not block your view or interfere with water or sewer
mains, telephone or cable wires, or gas or electric lines as it matures.
- Allow generous room for growth
Ensure that the tree will have plenty of room to grow; both downward
and outward into the ground and upward and outward into the air above.
Locate a tree away from houses or other structures by at least half of
its estimated mature height. For example, allow 25 feet on all sides of
a tree that will grow to 50 feet. Be sure to space large trees 50 feet
apart, medium trees 35 feet apart, and small trees 20 feet apart.
- Evaluate planting area conditions
Determine whether the chosen location receives shade, dappled shade,
part shade or full sun. Evaluate soil type and moisture levels.
The Dallas metropolitan area has three major types of soils:
- Blackland Prairie - Deep, alkaline, clay-like, drains slowly.
- Escarpment -Shallow, alkaline, rocky, drains well.
- Sandy Loam - A mixture of sand and clay, deep, acidic, drains well.
Be sure to check other soil conditions that will affect the future
growth and success of your trees such as low fertility, compaction and
pollution contamination.
Don’t guess about something as important as your soil. For more information on getting your soil tested, check out http://soiltesting.tamu.edu/ .
Look for the following when purchasing a tree.
- Select a tree with a straight, single leader.
- Avoid damaged bark.
- Avoid broken or damaged limbs.
- If tree is dormant, scratch the bark to make sure it is moist and green inside.
- Make sure the root ball is moist or the container and soil is moist and the roots are not exposed .
Your planting hole should be as deep as the root ball and at least
twice as wide. Be sure to slope and roughen the sides of the hole so
roots can grow easily through the surrounding soil.
Handle the tree gently by the root ball or the container to prevent
trunk damage. If the tree is in a container, lay the tree on its side
and roll the container until it slips off of the root ball. Using a
sharp knife, slice the root system in four places to prevent circling
root growth in the ground.
Place the tree in the
center of the hole, making sure that it stands straight. The bottom of
the root ball should sit on the undisturbed soil. The top of the root
ball should be even with but no more than 2” higher than the
surrounding ground. If the root ball is burlapped, carefully cut away
and remove all binding strings, wire and material.
Fill the hole halfway with original soil. Soak the soil with water to
remove air pockets. Then add the remaining soil and soak again. Do not
add any fertilizer to the original soil. The tree’s root system will
develop better without additives.
Add 2 to 3 inches of mulch to the planting area. Mulch insulates the
soil, arrests weeds, retains moisture, adds nutrients, and prevents
soil compaction. Be sure to keep mulch away from the tree trunk.
Water your new tree on a regular basis for the first two years to
encourage a strong root system. During the summer, water once weekly if
there is no rainfall. Keep the soil moist, but avoid over watering. Too
much water makes leaves yellow or fall off.
Remove any protective trunk wrapping. Studies show that trunk wrap can
retain unwanted temperatures and moisture against the bark and invites
and conceals insect infestations. Remove all tags and labels. Prune
away dead or damaged limbs. (Do no other pruning at this time.) Add an
expandable collar to the base of the tree for protection from lawn care
machinery.
Avoid staking the tree unless it is
totally unstable. Staking can prevent the tree trunk’s adjustment to
winds and prevent the development of flexibility and normal taper. If
staking is necessary, use broad, flexible material to secure the tree
to the stakes. Remove the stakes after one or two growing seasons.
