One of the best tools that you have as gardeners to help us determine your gardening schedule is the USDA zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Montevideo you can estimate when it's a good idea to plant hosta by reviewing the USDA zone info.

Planting Calendar for Hosta

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

Hosta are moderately cold tolerant which tells us that you can plant them a little bit earlier than other plants that might not handle the cold.

The earliest that you can plant hosta in Montevideo is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant hosta and expect a good harvest is probably August. You probably don't want to wait any later than that or else your hosta may not have a chance to really do well. You can get started a little bit earlier by starting your hosta indoors.
