DO MY TREES NEED HELP?

A rule of thumb is that native trees require less maintenance than planted trees. There are two main
reasons. One, native trees are obviously the best adapted to this area; therefore, they will need little help
acquiring their nutrients from the soil and will be able to tolerate the hot, dry Texas summers. Introduced
trees, however, have a difficult time penetrating the hard limestone. Another soil problem is pH level: it is
very high in Austin. There are many trees that are commonly planted in Austin and do not do well because
they prefer a lower pH. If your trees are not well suited to Austin soil then they probably need help.
If you don't know what kind of soil your tree likes, find out.

The second reason is that planted trees have to deal with establishing root systems. If the tree you planted
came in a burlap sack, then don't expect to see any growth for a least three years.

Balled and burlaped trees will be in shock for a least this many years as a result of the tree's massive loss
of root system that took place when it was dug up from the wild. During this time of stress, your tree will
be prone to insect and disease attacks. If your tree was balled and burlaped it probably needs help.

Construction damaged trees usually need help, too.

SOME SIGNS TO LOOK FOR:

Light yellow colored leaves.
Holes in leaves.
Edges of leaf turned brown.
Spots on leaves.
No leaves on very tips of branches.
Thin crown compared to trees of same species in same area.
Early fall color and leaf drop.
Sap oozing out of trunk.
Bark flaking off.
Mushroom on trunk.
Severe infestation of ball moss.
