Growing Green

with one comment

If you’ve visited The Arboretum this spring, have you noticed a few missing trees in the parking lot?


This past October, we removed 14 Catalpa trees from the parking lot found in the southwest corner of The Arboretum grounds.   Catalpas are beautiful park trees if planted in the right growing conditions, but unfortunately, our Catalpas were severely infected with Verticilium Wilt.  This fungus infects through the roots and is difficult to control once established.  Excess moisture from the spring exacerbated the infestation to the point of treatment and maintenance costs were no longer feasible.



 Thanks to a generous donation from Green Scene, The Arboretum will be able to replace the parking lot trees this spring.  We will replace the Catalpa with Honeylocust “Shademaster,” a successful street tree that is resistant to Verticilium Wilt and thrives in parking lot growing conditions. 


The Arboretum’s main objective has always been to provide a public green space for the education and enjoyment of our natural world.  The trees and flowers planted, classes taught and events hosted are the direct result of generous community organizations like Green Scene. 


Thank you, Green Scene, for your support!


If you would like to learn more about Green Scene, please visit their website at http://greensceneinc.org and plan on attending their annual plant sale on May 9, 2009.  The sale is 9:00 a.m. to noon at Cattle Congress in Waterloo.


**  Like most years, planting opportunities for 2009 exceed our abilities to plant.  There were other trees lost last season, but The Arboretum is choosing to only focus on the parking lot this year in order to not plant more that can be effectively cared for.  Also in 2009, the Planning & Operations Committee and Board of Directors will work together to develop a unified and simplified landscape design that emphasizes both horticulture and financial sustainability.

  1. I just heard that the Emerald Ash Borer is just across the Mississippi River in Wisconsin. Does the Arboretum have many ash trees?
