Black Oak also known
as Yellow Oak and Yellow Barked Oak is a
relatively slow growing oak, maturing with a broad round crown, leaves
are 4-10 inches long, 3-8 inches wide, usually 7 to 9 lobed, lobes are
bristle tipped, thick and leathery, somewhat deeply indented, shiny dark green above turning a red or brown in fall.
The Black oak flowers in May, when the leaves are half grown, producing
catkins 4-6 inches long. Black Oak acorns take two years to mature and are 1/2-3/4" long,
kernel is yellow and bitter. This oak tree will tolerate a wide range of soils
but grows best on moist, organic, well drained acid soils and is not an
important lumber tree and is hard to transplant due to taproot unless grown in root bags.
The wood is heavy, hard, strong, red and is usually sold with Red Oak for
flooring. The national champion Black Oak is 131' tall in St. Clair County, Michigan.
Black Oak is moderately drought tolerant, prefers sandy loam, well drained and
a touch on the acid side. Black Oak can withstand polluted air, full sun and
should be planted more as it is a good landscape tree. Black Oak is native to the following states:

Pests & Disease
Cottony maple scale is found rarely on Black Oaks.
These overwinter as immature females on branches. The eggs mature in
June when mock orange is in full bloom. The egg sacks look like a white
fungus on the oak twigs. Not a serious pest of the Black Oak. Flat headed
apple tree borer is a common pest of oaks, maples, lindens and
crabapples. The female lays her eggs in wounds or cracks in the bark.
The eggs hatch a few weeks after lilacs bloom. Remove any tree wrap in the
spring. Larvae may be removed by hand. Gypsy moth and eastern tent
caterpillars eat the leaves of most deciduous trees but seems to prefer
Oak.The larvae hatch in late Apriland develop quickly to
ravenous little monsters. A heavy infestation of gypsy moths can weaken Oak
trees. An insecticide like Sevin can control the caterpillar stage of
development. There are some good natural controls available now to control
caterpillar populations. Spider mites can be controlled
by a miticide. Two lined chestnut borer is a primary pest of
Oaks. The adults lay their eggs in the cracks on the bark in late June. The
larvae burrows into the wood and can't easily be killed. The borer takes up
to two years to mature and exits thru a D shaped hole similar to it's cousin
the Ash borer. Keeping the oak tree healthy will prevent allot of problems
including the borer. Oak wilt is a major concern
especially in the red and black oak groups. Trees can go from healthy to
death in a few weeks. Wilt is caused by a fungus that can be transported by
a picnic beetle or by root grafts. Although it can not be cured it can be
prevented by only doing your pruning on a Black Oak in the fall or early
winter. Phytophthora root rot is a soil born pathogen.
This is not a common pest of the Black Oak.
