One of the best tools that you have as gardeners to help us determine your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

It's a good idea to figure out when to plant hosta by using the USDA zone info for Evansville.

Planting Calendar for Hosta

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

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

The earliest that you can plant hosta in Evansville 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. If you wait any later than that and your hosta may not have a chance to fully mature. You can get started a little bit earlier by starting your hosta indoors.
