A way of getting a good idea when it's the best time to plant hosta is to examine the USDA zone info for Claremont.

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 fully mature. You can get started a few weeks earlier by starting your hosta indoors.
