Big gardening weekend in Montreal coming up

On my gardening calendar I see the Great Gardening Weekend put on by the Jardin Botanique de Montréal Friday through Sunday. On Saturday, Various Eco-quartiers around town are giving away annuals, perennials and, in some neighbourhoods, compost too. Saturday and Sunday, Gayla Trail's friend is holding her annual heirloom tomato sale. And there's a cleanup of the Champs des possibles in Mile End Saturday afternoon also.
