One of the first steps you take when you are estimating your gardening schedule is find your 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.

One way of figuring out when it's a good idea to plant canna is to look at the USDA zone info for Vista.

Canna do not do well in cold weather which means that it's necessary to wait until it warms up after the last frost before you can plant them.

The earliest that you can plant canna in Vista 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 canna and expect a good harvest is probably September. Any later than that and your canna may not have a chance to really do well. You can get started a little bit earlier by starting your canna indoors.

Last Frost Date
