Attention Horticulture Program Students

The 2020-2021 Catalog Year Programs of Study have been published (https://catalog.nvcc.edu/) and involve some considerable changes and improvements to the required courses for both Horticulture AAS Degrees. The following is to serve as a quick guide to these changes:

  • Remember that you will automatically stay in your current declared Catalog Year Program and that you can still graduate under that program. You may elect to be enrolled in the new Catalog Year Program if desired.
  • The following courses are considered equivalent (in degree requirement not in content) in all Catalog Years (but a course substitution request will still need to be submitted with your advisor):
    • HRT 251 Site Engineering is equal to HRT 259 Arboriculture
    • HRT 252 Construction Drawings is equal to Any Approved HRT Elective
    • HRT 246 Herbaceous Plants is equal to HRT 201 Landscape Plants I
    • HRT 247 Indoor Plants is equal to HRT 202 Landscape Plants II
    • HRT 125 Chemicals in Horticulture is equal to CHM 101 or higher

(HRT 125, HRT 251, HRT 252 have been eliminated from the program, HRT 246 and HRT 247 have been replaced with HRT 201 and HRT 202)

  • In most cases, if you are close to completion, it makes sense to stay in your current (historic) Catalog Year Program.
  • If you have specific types of financial aid or are relatively new to the Horticulture Program, it might make sense to elect to the new Catalog Year. Please contact your Advisor or Horticulture Instructor for specific questions.

Spring Plant Sale Cancelled

Please note that the spring plant sale has been cancelled due to COVID-19. Please contact us if you have any questions about the plant sale.

Every year The Horticulture Club hosts a Poinsettia sale inside the Loudoun Greenhouse during the first week of December. Many varieties of specialty Poinsettias are ordered in and then grown on by students until they are ready for the sale.

The club also grows a variety of annuals for two plant sales that are held in April. The spring campus greenhouse plant sale and the annual Leesburg Flower and Garden Festival in downtown Leesburg.

The Horticulture Department hosts a monthly Horticulture Club Meeting, taking part in trips, discussing market trends, events for members, and student presentations. The Horticulture Club is also in the works of offering scholarships and have scholarships available from outside organizations.

My life has been a continuing journey working more and more closely with plants. My original interest in horticulture and plant science began with growing edible plants and has since expanded to include all aspects of the plant kingdom but with a special interest in edible gardening (especially fruit), rare and unusual plants of all types, and trees and woody plants. I also value practices that are sustainable and align myself with the environmental and food justice movements. I have been teaching college-level horticulture classes since 2012 and began teaching at NOVA Horticulture full time in January 2018 after completing my MS in Horticulture from UC Davis in 2017 where I conducted research with USDA-ARS scientists in the National Plant Germplasm System (doing a phenotyping study of the National Prunus persica collection). I also have a bachelor’s degree in interdisciplinary studies from UC Berkeley. I have worked professionally in the field of horticulture since 2005 (farming, USDA forest service, nursery management, public gardens management, horticulture and greenhouse technician, and as a small business owner). I have been studying horticulture since 2007 at the college level, and gardening since I ran over tomato hornworm caterpillars on my tricycle in my father's vegetable garden in the Mojave desert of California. My wife is from Maryland and we are now happy to be in the Chesapeake Bay region raising our twin daughters.

I grew up 10 minutes from Longwood and Winterthur Gardens and with such extraordinary inspiration, I couldn’t avoid becoming a horticulturist! Over the years I have sustained a deep commitment to horticulture as a greenhouse perennial plant production grower, garden designer, and horticulture educator. While working on my Masters of Science in Horticulture at Virginia Tech, I produced a manual titled “Designing Sustainable Landscapes for Small Towns.”

Many of my horticultural accomplishments and writings were widely recognized at my previous posts as horticulture manager at Keswick Hall and Woodberry Forest School near Charlottesville, Virginia.

Expertise and Teaching

  • HRT 100 Introduction to Horticulture
  • HRT 115 Plant Propagation
  • HRT 121 Greenhouse Production
  • HRT 201 & 202 Landscape Plants I &II
  • HRT 207 Plant Pest Management (Plant Health Care)
  • HRT 245 Woody Plants

I have an extensive background in production horticulture which has provided me with a wealth of hands-on experience that I apply in the classroom every day. Additionally, I am an ISA certified arborist with the International Society of Arboriculture. I thrive in the practically-minded nature of the community college experience as I instruct and mentor my students.

In my free time, I enjoy searching for Big Trees, civic involvement with my church, dogs, photography, and hiking in as many National Parks as possible!

  • B.S. Plant Science, University of Delaware
