Before planting it is a good idea to find your USDA Zone info to estimate your garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Ontario you can estimate when you can plant millet by reviewing the USDA zone info.

Planting Calendar for Millet

It's probably not a good idea to plant millet until after the last frost has passed because they require warm weather.

The earliest that you can plant millet in Ontario is April. However, you really should wait until May if you don't want to take any chances.

The last month that you can plant millet and expect a good harvest is probably August. Any later than that and your millet may not have a chance to really do well. Starting your millet indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

It's important to remember that USDA zone info for Ontario is just an average and the actual date of last frost is different every year. Half of the time in Ontario you get a frost after April 15 so just be sure to be ready to protect your millet if you have a late frost.
