Before planting it is a good idea to find your USDA Zone info to figure out your garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Portales you can determine when you can plant hosta by referring to 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 ok in mild cold which means that you can plant them a little earlier in the year than other plants that might not handle the cold.

The earliest that you can plant hosta in Portales 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. You probably don't want to wait any later than that or else your hosta may not have a chance to grow to maturity. If you are starting your hosta indoors then you might be able to get away with starting them a few weeks earlier.
