Tyrone Brown, Sr.
At Brown's Tree Care we believe that it is important to
stay up to date and educated on current research in the
Arboriculture Community. That's why we regularly attend
classes and seminars taught by some of the top researchers
of Arboriculture in the nation.

Why Prune?
"Why should we prune our trees?" is a question
we get asked often. When done correctly, pruning trees is
healthy. Broken, dead, or diseased branches are pruned to
prevent pathogenic organisms from penetrating into adjacent
parts of the tree and to reduce spreading to other trees.
Pruning is an important control measure for fire blight,
black knot, several twig blights, some cankers, and crown
gall. Live branches are removed to permit penetration of
sunlight and circulation of air through the canopy. An open
canopy makes a less favorable site for fungus and bacteria.
Proper pruning of the tree crown can reduce wind resistance
and help prevent breakage. Branches that form an acute angle
of attachment are removed because they are especially prone
to breakage.
When branches having narrow crotch angles enlarge stress
on the crotch increases. Also, acutely angled braches often
have bark embedded (we call this included bark) in the branch
attachment, which causes a weak joint. These weak attachments
are prone to splitting and breaking out during ice storms
or high winds. Thus pruning can increase the structural
stability of trees.
About Mistletoe?
 Mistletoes
are parasitic plants that grow on woody plants taking nutrients
and moisture from their host. They infect many host. They
infest many trees especially Hackberry, Ash and Maple in
Texas. Mistletoes have green or gray-green stems and leaves.
The leaves are oval shaped, thick and firm in texture.
After mistletoe plants are 2 years old, they begin to grow
small white or pinkish berries that build up a pressure
inside and explode shooting sticky spores sticking to other
parts of the tree to reproduce. Humans and birds also spread
Mistletoe. If not removed, Mistletoe can seriously weaken
trees.
Special Note: Mistletoe plants are poisonous to humans.
