The 4 Zones

[wbfd22]

Since I'm new to this site, I find it quite interesting that different topics talk about what "zones" they are planting in

How do you classify each zone?? I live in Ontario, Canada. This means we have warm temperatures for approximately 4 months of the year, cooler temps for another 2-3 and snow for the other 6!! So which Zone am I in when I'm researching on this site??

Thanks for your help.....I'm quite enjoying this site!!

Your can find your Canadian Zone here:

The Atlas of Canada - Plant Hardiness Zones

You can roughly translate the USDA hardiness zones by finding out how low your area's temperatures can reach, and then use the chart below to find your corresponding zone. Zone 1: below -46 C (below -50 F)
Zone 2: -46 to -40 C (-50 to -40 F)
Zone 3: -40 to -34 C (-40 to -30 F)
Zone 4: -34 to -29 C (-30 to -20 F)
Zone 5: -29 to -23 C (-20 to -10 F)
Zone 6: -23 to -18 C (-10 to 0 F)
Zone 7: -18 to -12 C (0 to 10 F)
Zone 8: -12 to -7 C (10 to 20 F)
Zone 9: -7 to -1 C (20 to 30 F)
Zone 10: -1 to 4 C (30 to 40 F)
Zone 11: above 4 C (above 40 F)
