Columnar English Oak

Description

The Columnar English Oak is a compact specimen perfect for small spaces, such as between a sidewalk and the street. Its narrow upright branches create a condensed pyramid of dark green leaves in the typical oak shape.

Planting Tips

Thirves in open, sunny areas with well drained soil. Give it consistent moisture, especially the first year after planting and fertilize with an all purpose slow release fertilizer in spring.

Suggestions

I was drawn to this tree for a couple of reasons. I found their small, classic "oakleaf" foliage and handsome acorns very appealing, but it was their strict columnar growth that really got my attention. You see, while this tree will grow to a whopping 50 feet plus when it matures, its width will never exceed much more than 10 feet. Standard English oaks, on the other hand, produce a tremendous spread with their limbs, often surpassing the height of the tree. So you can understand why this tall, thin oak is a welcome addition to the urban landscape scene. It took 3 years from the time I planted my "magnificent seven" to see them respond with some vigorous growth, but now they tower above the sidewalk nearly 20 feet.
