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.

The first chance to plant hosta in Piedmont should be figured out 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.

Hosta do well in a little bit of cold which tells us that you can plant them a little bit earlier in the year than other frost tender plants.

The earliest that you can plant hosta in Piedmont 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. 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 couple of weeks earlier.

Last Frost Date

On average the last frost has passed is on April 15 in Piedmont. In the coldest months of winter you should expect an average low temperature of 5°F.

Since the USDA zone info for Piedmont may not be accurate from year to year the actual date of last frost changes from year to year. Half of the time in Piedmont there is a last frost after April 15 so just be sure to be ready to protect your hosta in the event of a late frost.
