Since hosta are moderately cold tolerant you can plant them just a bit earlier in the year than plants that are more sensitive to the cold.

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. Starting your hosta indoors is a great way to get them started a little bit earlier.
