Before planting it is a good idea to find your USDA Zone info to estimate 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 common way of making a decision about when it's possible to plant hosta is to consult the USDA zone info for Pittsburg.

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 moderate cold which means that you can plant them a little bit earlier than other frost tender plants.

The earliest that you can plant hosta in Pittsburg is January. However, you really should wait until February if you don't want to take any chances.

The last month that you can plant hosta and expect a good harvest is probably October. Any later than that and your hosta may not have a chance to grow to maturity. Starting your hosta indoors is a great way to get them started a few weeks earlier.
