The USDA Zone info is a great tool for gardeners to help us determine your gardening schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Inverness you can estimate when it's possible to plant hosta by looking at the USDA zone info.

Planting Calendar for Hosta

When to plant:	Up to 5 weeks before last frost.

Hosta tend to make it in some cold which means 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 Inverness 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. You probably don't want to wait any later than that or else your hosta may not have a chance to grow to maturity. You can get started a few weeks earlier by starting your hosta indoors.
