Cherry Tree Removal at CUH

March 14th, 2012 by Soest Gardener, Riz Reyes

Our row of cherry trees along the driveway at CUH are scheduled to be removed this Thursday, March 15.

Though they’re starting to bloom, we have a severe infestations of blossom brown rot, a common fungal disease of cherries in the Pacific Northwest.

Fungicdal treatments are not a sustainable option. Our decision to display healthy plants available in the trade has left us with the option to choose plants that will be more adaptable to this site.

For more information, check out a post composed by Horticulture Supervisor, David Zuckerman, on the early flowering cherries along Azalea Way in Washington Park Arboretum.

Notice of Garden Renovation: Soest Garden Specimen Tree

October 4th, 2011 by Soest Gardener, Riz Reyes

Our Persian Ironwood tree slated to be replaced later this fall/winter

So after 13 years in the same raised bed, it’s time that one of our Persian Ironwood trees (Parrotia persica) be removed and replaced with another species.

It was suggested that every ten years or so, the specimen tree would be changed out to showcase different species that could be utilized to create the part shade environment intended for the perennials planted below. There’s also concern that a mature tree’s roots could damage the concrete wall if allowed to get large.

After leaf-drop this fall/winter, we will close off the Soest Garden for a day or so and have the tree removed. Some of the soil will be replace (and perennials moved temporarily, of course) and our new tree, a American smoke tree Continus obovatus, will be planted.

We will begin digging up perennials shortly and keeping them in the nursery until they can be replanted in the same bed. Signs will be posted describing the project and further notice will be made when the date of renovation is determined.
