The Ground Gets Lower

Wednesday, April 17, 2024
7:30 pm

"Ground gets Lower” Advise for all gardeners on how to stay gardening longer and maybe learn some new tricks on the way.

Aging, round, humour in a nutshell I was a chef for over 20 years, Blacksmith, Horse trainer, Riding instructor but the ones you want to know is my own Garden maintenance business for way too long, 40+ years and my clients are in majority, seniors, I am also a Horticultural and Design judge, so yes I know a little about a whole bunch of plants, was also OHA Director of District 6 which is a big area with 21 hort societies and in 2023 retired from the board of OHA as the Southwest rep where I helped the directors of all the other districts. Officially retired from it all, but you know once a volunteer always a volunteer. Still the admin on a bunch of Facebook pages, gardenontario the OHA’s group, District 6 page and Haldimand Horts page. My moto I strive to maintain is; if you can’t see the humour in what you are doing, Why are you doing it?

Rethinking Beauty: Inspiring Gardeners in a Changing World

Wednesday, June 21, 2023

This presentation will challenge us to ask, and maybe answer the questions: do you ever wonder how and why you garden? Are we just striving for something that is aesthetically pleasing to the eye? With 30 plus years of experience in the horticulture industry, Paul now finds himself questioning some traditional gardening practices as we face both climatic and biodiversity challenges. He believes we must have a closer look at the important role both private and public gardens play beyond their property lines.

Dreamers, Schemers and Builders: 
An Intro to the History of Royal Botanical Gardens

Wednesday, May 17, 2023

Royal Botanical Gardens is both Canada’s largest botanical garden and a group of important natural areas totalling over 1,000 ha. Its origins are a complex and fascinating story with roots in plans to beautify Hamilton in the early 20th Century. Thomas Baker McQuesten, a Hamilton politician and lawyer, developed the concept for a botanical garden of national significance in Hamilton after visiting RBG Kew and RBG Edinburgh in 1924. The city’s Board of Park Management promoted the idea, acquiring the first land in 1927. By 1934 Hamilton had more land in parks than any other city in Canada; much of it would later become RBG.
