The USDA Zone info is a great tool for gardeners to help us estimate your gardening schedule. 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 you can plant myosotis is to examine the USDA zone info for Adel.

Planting Calendar for Myosotis

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

Since myosotis do well in moderate cold you can plant them a little earlier in the year than other frost tender plants.

The earliest that you can plant myosotis in Adel 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 grow to maturity. You can get started a little bit earlier by starting your myosotis indoors.

In Adel the average date of last frost happens on March 15. You should expect an average low temperature of 15°F in the coldest months of winter.

Since the USDA zone info for Adel is not always accurate the actual date of last frost changes from year to year. Half of the time in Adel it frosts late in the year after March 15 so always be ready to cover your myosotis in the event of a surprise late frost.
