One of the best tools that you have as gardeners to help us figure out 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 Vail you can estimate when to plant heuchera by referring to the USDA zone info.

Planting Calendar for Heuchera

Frost tolerance for heuchera:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Since heuchera do well in moderate cold 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 heuchera in Vail 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 heuchera and expect a good harvest is probably August. Any later than that and your heuchera may not have a chance to really do well. Starting your heuchera indoors is a great way to get them started a little bit earlier.

Last Frost Date
