The Story

Native to a large area of the East and Midwest, the majestic Bur Oak is a part of our nation’s natural heritage. It is an iconic tree of farmlands and prairies, where venerable old specimens add their bold silhouettes to otherwise flat, wide open landscapes. Small groupings of Bur Oak serve as windbreaks from the never-ending winds that howl across the Plains. Birds gather in its branches, and deer, squirrels, and wild turkeys eat its acorns. Bur Oak gets its name from those jumbo-sized acorns, which are held in very large caps covered with a bur-like fringe. The oversized caps and acorns have a lot of character and make fun additions to fall craft projects.

The Details

Bur Oak is a supremely tough tree, able to shrug off bitter cold, drought, wind, and poor soils like few other trees can. This gentle giant can even survive in the city if there’s room enough for it to grow. In fact, Bur Oak is a past winner of the Society of Municipal Arborists Tree of the Year award for its ability to thrive in challenging urban sites.

How to Grow

Bur Oak is a slow-growing tree, but with optimum levels of water and fertilizer, its growth rate can be speeded up a bit. Use the Bower & Branch™ Water Element and our Soil Enhancer and Fertilizer Element to give your new tree exactly what it needs to flourish. Plant Bur Oak in full sun in any type of soil and mulch it with a layer of wood chips or bark. Make sure to also give it plenty of elbow room! Diseases and insect pests are generally no problem with this one, and you’ll rarely have to prune it.
