Why do you want to plant a tree there?

Plant trees October through February
Preparing to Prune
How you
plant a tree will impact its entire life.
The right tree in the right place.

About poor nursery stock...
what to do when trees don't come with good structure?
The right tree,
at the right depth, with healthy roots, with water and mulch.
Planting and Pruning Best Practices
Structural Pruning at Planting
How you prune
a tree at planting will impact its entire life.
Leaves are food factories.

Chemicals produced in buds promote root growth.

Sugars produced by leaves help to feed the trunk and make it grow stronger.
Reduce structural defects
Create smaller wounds
Prune at Planting to:
Did You Know?
Step 1) Inspect your tree.
Visualize the mature tree.
Did You Know?
Limbs of a tree don't grow 'up'. They stay in place but continue to get larger.
Step 2) Identify a Main Leader
Trees with one main leader are more stable at maturity.
Look for:
Competing stems
Branches growing upright rather than horizontal
Crossing branches which may rub together
Dead or broken branches
Prune just enough to correct any problems and not so much that the tree is harmed.
Remove or Subordinate stems that will compete with the leader
Dead and broken branches
Crossing Branches
Know Your Pruning Cuts
Branch collars/branch bark ridges
Use 3 point cuts to prevent tearing...
Prevent Oak Wilt:
Prune at the hottest or
coldest time of the year.
Always sterilize tools before use.
Always paint your wounds on oak trees.
Important for long term tree health and survival
Provides best value to customers
Lower temperatures reduce transplant shock

Deciduous trees are dormant

Sometimes (not always) it rains more

Provide more value to customers
Make a plan!
Remember that this tree has the potential to become....
This big

Co-dominant stems tend to have 'included bark', and are more likely to split apart.
Joseph O'Brien, USDA Forest Service, Bugwood.org
Did you know?
Trees don't "heal", but can only try
to wall off a wound before it begins to decay.

Smaller wounds are more likely to close over before they decay than larger wounds.
Small pruning cut which has been successfully "walled off"
Larger wound which has begun to decay.
Happy customers...
Turn into repeat customers.
Many of the branches on a newly planted tree are temporary. They will not remain on the tree once it is mature.
Make your pruning cuts...

Caring for Trees During a Drought
Mulch Your Trees
Mulch helps to...
Insulate roots from temperature extremes
Reduces competition between turf, weeds,
& tree roots
Water Your Trees
Water at least once every two weeks during dry periods

Water about 5-10 gallons/inch trunk diameter

Apply water slowly for best absorption
For More Information...
Don't Hurt Your Trees
Fertilizers and 'Weed & Feed' can hurt trees, especially when applied during hot and dry conditions.
Herbicide Damage
Fertilizer Damage

~ Main Leader: a stem which will become the trunk of the tree
Joseph O'Brien, USDA Forest Service, Bugwood.org
Imagine the Full Grown Tree
Check Planting
Depth in Container
Dig the perfect hole: right depth and width
Remove container or burlap
Create soil ring
Water slowly and thoroughly
Stake the tree only if necessary
Adds organic matter and nutrients to soil
Slows moisture evaporation
Protects tree trunks from lawnmower and weed eater damage
Thank you for taking care of Austin's urban forest!
Use the 1/3 Rule
Prune a branch back to another branch at least 1/3 the size of the one being removed
Don't make 'topping cuts'
