Phenology explores the timing of cyclical events in nature. Your garden is part of the natural world. Rebecca Last Guenette is a scientist and Master Gardener. She wants you to know that if you tend your garden and pay close attention to how it works and develops during the seasons that you're a 'phenologist'.

She says , "Scientists today are increasingly turning to phenology to understand how climate change is affecting the natural world. As gardeners, an understanding of phenology can help us plan for continuous blooms, use natural pest control effectively, and contribute to climate research as citizen scientists.

In this episode we talk Victoria Day planting, earwig explosion, newly updated Canadian Hardiness Zones and Artificial Light At Night. It's a fun episode hosting by friend of The Garden Shift Tena van Andel and full of good advice.

Welcome to Season Three. This episode was recorded onsite at the Toronto Plant Market. As ecological gardeners it's important to know where your plants come from- who grows and sells them. If you are in and around Toronto this is the place to go. You will meet the owner Jonas and his terrific staff. When you visit go with questions and leave with answers. Plants are organized by ecological reference based on characteristics of the most common sites in Toronto- lawn alternatives, woodland, edible, hardscape, meadow/prairie and wet.

You may remember Douglas from Season 2. His storm infiltration boulevard in Etobicoke is well documented. Douglas joins to continue the conversation about all the critters who visit this garden space- grasshoppers, damselflies, wasps, bees and birds to name a handful few.

In this episode we continue on the theme of naturalized gardens and out dated by-laws that penalize gardeners who want to do their part for nature. The City of Burlington is taking ecologist Karen Barnes to court over her naturalized garden, that was deliberately planted, maintained, free of noxious weeds and not obstructing any sidewalk or sightline. It's been a battle that has seen her front and back garden mowed down by the City.

Listen in to Karen joined by her daughter Julia as they detail the case based on constitutional grounds and their aim to set a strong precedent in support of Canadians’ rights to freedom of expression through gardening.
