OHS Fall Issue of The Dibbler

The Fall issue of The Dibbler is out now!

Our award-winning*, member-driven publication is now available. With “Garden Stories in Black and White” you can cozy up with inspiring and beautiful articles written and illustrated by fellow OHS members. Take a look back at summer with a behind-the-scenes tour of the Royal Botanical Gardens, and think ahead to winter with tips for growing edible greens indoors. Read a killer book review and, just in time for Hallowe’en, take a walk through a garden that glows in the moonlight and lurks in the shadows. Learn about one of the lesser-known garden tools and Canada’s first Dominion Botanist. Regular columns include a specially curated list of new titles from the Ottawa Public Library’s collection and a peek inside the garden of an OHS Board member.

Lots to read on these crisp autumn days!

OHS and the Canadensis Native Tree Nursery Project

This year, OHS is happy to announce it has joined with Canadensis and the Ottawa Field Naturalists’ Club on a new initiative: “Canadensis Native Tree Nursery Project.”

This initiative has been welcomed by OHS members. It involves planting, overwintering, and growing native tree seeds. Once the seeds germinate and grow into young trees, they will ready to be moved to a native tree nursery established at Canadensis, with funding from the City of Ottawa, located on the planned site of a botanical garden near Dow’s Lake.

The long-term goal of this project is to improve biodiversity in the region. For further information on this project, please contact Kathleen Fischer at kfischer888@outlook.com or Jean Carr at jcarr@jardincanadensisgarden.ca.

Additional details available by clicking on the button below where you will be able to view, download and/or print the background, info and planting instruction sheet.

Note, participation in this project is open to members and the public.
