Before planting it is a good idea to find your USDA Zone info to figure out your garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

A way of estimating when to plant hosta is to refer to the USDA zone info for Concordia.

Planting Calendar for Hosta

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

Hosta do well in some cold which means that you can plant them just a bit earlier in the year than other frost tender plants.

The earliest that you can plant hosta in Concordia 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 hosta and expect a good harvest is probably September. 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
