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.

A way of making a decision about when it's the best time to plant anchusa is to examine the USDA zone info for Gallup.

Planting Calendar for Anchusa

Frost tolerance for anchusa:	Very tolerant of frost.
When to plant:	Up to 7 weeks before last frost.

Anchusa are very cold tolerant which means that you can start planting them much earlier than other frost tender plants.

The earliest that you can plant anchusa in Gallup 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 anchusa and expect a good harvest is probably September. Any later than that and your anchusa may not have a chance to grow to maturity. Starting your anchusa indoors is a great way to get them started a little bit earlier.

Last Frost Date

Since the USDA zone info for Gallup may not be accurate from year to year the actual date of last frost is different every year. Half of the time in Gallup there is a last frost after April 15 so always be ready to cover your anchusa in the event of a late frost.
