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 estimating when to plant hamelia is to check out the USDA zone info for Flagstaff.

When to plant:	After all chance of frost has passed.

Since hamelia require warm weather you have to wait until after the last frost has passed before you can plant them.

The last month that you can plant hamelia and expect a good harvest is probably August. You probably don't want to wait any later than that or else your hamelia may not have a chance to grow to maturity. If you are starting your hamelia indoors then you might be able to get away with starting them a little bit earlier.
