Before planting it is a good idea to find your USDA Zone info to figure out your garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

The first chance to plant hosta in Zone 2b can be estimated by looking at 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 one of those plants that can tolerate a little bit of cold weather you can plant them a little bit earlier in the year than other plants that might not handle the cold.

The earliest that you can plant hosta in Zone 2b is April. However, you really should wait until May 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. Any later than that and your hosta may not have a chance to really do well. Starting your hosta indoors is a great way to get them started a little bit earlier.

Last Frost Date

Since the USDA zone info for Zone 2b is not always accurate the actual date of last frost can change quite a bit from year to year. Half of the time in Zone 2b it frosts late in the year after May 15 so make sure that you are ready to protect your hosta in the event of a surprise late frost.
