Bloom Season – Usually blooms in May and possibly as early as April, depending on weather conditions.
Bloom Color – Male flowers first show up in yellow-green oak catkins. The leaves of the white oak are bluish-green.
Height at Maturity –The white oak tree can grow to a height of 50’ to 80’.
Soil Type Preferred – White oaks prefer slightly acidic to neutral soil that is moist, well-drained, and deep.
Sun or Shade – Full sun is best, but they also do well in partial shade with at least 4 hours of direct, unfiltered sun per day.
White oak trees make an excellent shade tree for any yard with a canopy spread of 50’ to 80’.
During the fall, the leaves of the white oak tree turn beautiful shades of red or burgundy. They are known for their solid branches and can live for centuries. White oaks are a fairly slow-growing tree that grows about 12 inches to 24 inches per year.
Even though they prefer well-drained acidic soils, they tolerate alkaline, shallow, or urban soils.
They will survive dry or drought periods and occasionally wet soils. White oaks are sensitive to changes in grades and compacted soils. They have a deep taproot that makes them hard to move or transplant once they are established.
Like other oak trees, white oaks produce acorns. Their acorns are as large as 1 inch, with a cap covering the top quarter of the acorn. They do not produce acorns every year, and they can start producing acorns when they are 20 to 30 years old. Weather conditions like excessive rain, drought, and wind can affect acorn production. Acorns from white oak trees mature in a single season.
