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 estimating when it's a good idea to plant hosta is to refer to the USDA zone info for Minot.

Planting Calendar for Hosta

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

Hosta can survive in moderate cold which means that you can plant them a little bit earlier in the year than other frost tender plants.

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

Last Frost Date

In Minot the average date of last frost happens on May 15. In the coldest months of winter you can expect an average low temperature of -30°F.

Just be sure to remember that the actual date of last frost is an average because it is based on the USDA zone info for Minot and it will vary from year to year. Half of the time in Minot it frosts late in the year after May 15 so make sure that you are ready to cover your hosta in the event of a late frost.
