Caitlin Ayling
Horticultural Consultant

Caitlin began her career in horticulture after graduating from Niagara College’s Horticultural Technician program in 2014. After a summer internship creating and managing a research trial garden followed by a season growing miniature roses under the greenhouse sun, she found her way to NVK Nurseries. She started in the propagation department, moving into the head grower position and putting her knowledge and practical experience to the test. After a few years, Caitlin followed her passion in plant health and narrowed her focus to integrated pest management in the greenhouse and outdoor container settings. 

When Caitlin isn’t scouting, spreading beneficial insects, brainstorming and planning with her fellow growers, she can be found enjoying her backyard space with her partner Andrew, daughter Kinsley and their dog Ollie. Living in Dundas, and backing onto the Niagara escarpment, allows Caitlin and her family to explore the green spaces and hiking trails right outside their door. Caitlin also enjoys working in her vegetable garden, battling backyard invasive species and promoting and incorporating more native plants in the landscape.
