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

In Montevideo you can figure out when to plant myosotis by reviewing the USDA zone info.

Planting Calendar for Myosotis

Frost tolerance for myosotis:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Since myosotis are moderately cold tolerant you can plant them a little bit earlier in the year than other frost tender plants.

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

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

Last Frost Date

The average date of last frost is May 15 in Montevideo. You should expect an average low temperature of -25°F in the coldest months of winter.

Since the USDA zone info for Montevideo is just an average the actual date of last frost is different every year. Half of the time in Montevideo there is a last frost after May 15 so just be sure to be ready to cover your myosotis if you have one of those late frosts.
