Before planting it is a good idea to find your USDA Zone info to estimate 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 figuring out when it's possible to plant begonias is to consult the USDA zone info for Richland.

The last month that you can plant begonias and expect a good harvest is probably August. You probably don't want to wait any later than that or else your begonias may not have a chance to fully mature. You can get started a few weeks earlier by starting your begonias indoors.
