Growing Rare Conifers

Growing Rare Conifers

Posted by: Mark Krist

My name is Mark Krist. I received a Bachelors of Science degree through the College of Agriculture, Food and Environmental Sciences as an Urban Forester via the Natural Resources Management Department in 2007. I now serve as an Urban Forester through the College of Science & Math under the direction of Dr. Matt Ritter, Director of the Cal Poly Plant Conservatory. As the Urban Forester of the Cal Poly Plant Conservatory, I have had the pleasure to be involved in many important projects including the maintenance of this collection of rare conifers.

The attached pictures are of a collection of rare conifers currently being grown at the Leaning Pine Arboretum and slated to be planted in the future Math & Science Complex. The rare conifer collection is composed of 45 specimens representing 33 individual species. Recently the whole collection was transplanted to larger containers to promote continued growth. This was the second time the collection was “bumped.” The growing of the specimens on campus prior to the installation saves money and provides time to grow to a larger size.

This project is of particular interest because it represents a collaboration among the Horticulture and Crop Science Department (using the Horticulture Unit for space and resources), the College of Science & Math (the Cal Poly Plant Conservatory in the form of plant selection and maintenance) and the Cal Poly Grounds Department (who are the eventual landscape designers, and will install and maintain the plants). This collection is to be installed mid-2013 and that there are currently Landscape Architecture students formulating plans for class projects.

I would invite you to come visit the rare conifer collection at the Horticulture Unit, located in the Courtright shade house, to meet some new and fascinating specimens. All specimens are labeled and coincide with the following current container size listing.
