When to plant:	After the last frost when the weather gets warmer.

Since nolana do not do well in cold weather you need to wait until after the last frost before you can plant them.

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

The last month that you can plant nolana and expect a good harvest is probably September. You probably don't want to wait any later than that or else your nolana may not have a chance to grow to maturity. If you are starting your nolana indoors then you might be able to get away with starting them a little bit earlier.

Last Frost Date

The average date of last frost is January 31 in Ontario. You should expect an average low temperature of 30°F in the coldest months of winter.

It's important to remember that the actual date of last frost is just an average because it is based on the USDA zone info for Ontario and it will vary from year to year. Since half of the time in Ontario last frost occurs after January 31 be ready to protect your nolana in the event of one of those late frosts.
