Before planting it is a good idea to find your USDA Zone info to determine your garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

One way of determining when it's the best time to plant hamelia is to examine the USDA zone info for Roma.

Hamelia do not do well in cold weather which tells us that it's necessary to wait until it warms up after the last frost has passed before you can plant them.

The earliest that you can plant hamelia in Roma 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 hamelia and expect a good harvest is probably September. You probably don't want to wait any later than that or else your hamelia may not have a chance to grow to maturity. Starting your hamelia indoors is a great way to get them started a few weeks earlier.

Last Frost Date
