About Mint
Mint is extremely vigorous — grow in containers to prevent it from taking over your garden.
Plant in a container always — mint will spread aggressively otherwise. Harvest regularly to encourage bushy growth. Cut to the ground occasionally to rejuvenate. Easy to overwinter indoors.
Gardening in Ontario
Ontario spans several climate zones. Northern Ontario is Zone 3-4 with short seasons; southern Ontario is Zone 5-7 with long productive seasons. The Niagara Peninsula is one of Canada's premier fruit-growing regions.
