Karen Rissmeyer Selected as an Ohio Master Gardener of the Year

November 2024

DCMGA is very pleased to announce that Karen Rissmeyer has been named as one of only five Master Gardeners of the Year selected by OSUE!  

Her name was submitted  as a result of Karen's excellence in providing environmentally sound, research-based gardening practices to Delaware County school children.  

Although she only interned In 2022,  she has provided hours of education to children attending Dublin, Olentangy, and Delaware County schools, as well as a Brownie Troop, and at the Stratford Ecological Center.   All told she has taught more than 28 sessions In 14 different classrooms.

Karen accepted the role of Youth Garden Resources and Education  (YGRE) team leader in 2023 and has enlarged the program by involving more DCMGA members in the project and utilizing the knowledge, skills, and interests to develop more gardening subjects.

Immediately after earning MGV certification, Karen began volunteering at the Ohio Heritage Gardens (OHG), where she logged over 100 volunteer hours in 2023 alone.  She was chose by Hope Taft to serve as a formal OHG Tour Guide during the 2024 growing season.

We all congratulate Karen on her well-earned accolade and are sincerely grateful that she is part of DCMGA! 

Therapeutic Gardening Team

November 2024


We had such a great time with our friends at the Avalon of Lewis Center this month! Delaware County Master Gardener Marlene Suter shared with all of us her love for spring flowers. Marlene demonstrated for the residents how to plant bulbs in pots using the lasagna method. Our gardening friends said no to gloves and proceeded to dig into the soil with their bare hands! 

The residents planted a mixture of Barcelona/Triumph, Princely Mix, Single Late Pastel, and Jimmy Mix Triumph Tulips, with Sunlight and Thalia daffodils and Grape Hyacinths. Pumpkin muffins and pumpkin spice meringues were enjoyed by all.


A total of 10 large pots will be stored in the greenhouse until next spring when we look forward to the grand display. The tulips represent the Love, Friendship and Joy we share with our friends. The Daffodils symbolize the rebirth and hope of Spring, and the grape hyacinths embody sincerity. We are sincerely grateful to the Avalon of Lewis Center for welcoming us each and every month and wish them all a Happy Thanksgiving!

Here are the steps for the lasagna method of planting tulips:
