One of the best tools that you have as gardeners to help us figure out 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.

In Chester you can determine when it's possible to plant hosta by checking out the USDA zone info.

Planting Calendar for Hosta

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

Since hosta are moderately cold tolerant you can plant them just a bit earlier in the year than other frost tender plants.

The earliest that you can plant hosta in Chester 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 really do well. If you are starting your hosta indoors then you might be able to get away with starting them a little bit earlier.
