Plant an Oak!
(But not a Pin Oak)

Created by The Midwest Tree Whisperer a friend of our local urban trees, in association with Grow Native

Our great state of Missouri is the native home to a diversity of native oak species adapted to a variety of site conditions - from the rocky hilltops of the Ozarks, to the rich soils of the valleys, and the fertile basins of our wonderful rivers and streams.

Why NOT a Pin Oak, a Missouri native species?
While pin oaks thrive and prosper in their bottomlands, trees planted in alkaline (high calcium) soils develop iron chlorosis, which leads to poor health and yellow to yellowish-green foliage - a common condition exhibited on prairie soils and at many of our urban and suburban landscapes containing significant deposits of crushed limestone remaining from construction site activities.

Choose the RIGHT tree for the RIGHT place.
Choose the RIGHT tree for the RIGHT place. With our native oaks, there are alternate species to choose which are better adapted to the challenging conditions of urban and suburban sites with significantly disturbed soils - high clay content and high soil PH (alkaline) - along with the rigors of our diverse climatic environment.
