One of the best tools that you have as gardeners to help us estimate your gardening schedule is the USDA zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

One way of making a decision about when it's possible to plant myosotis is to consult the USDA zone info for Oak Grove.

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 plants that are more sensitive to the cold.

The earliest that you can plant myosotis in Oak Grove 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 myosotis and expect a good harvest is probably September. Any later than that and your myosotis may not have a chance to fully mature. Starting your myosotis indoors is a great way to get them started a few weeks earlier.
