Gerbera are one of those plants that can tolerate a tiny bit of cold weather which means that you can get them planted just a bit earlier than other plants that might not handle the cold.

The last month that you can plant gerbera and expect a good harvest is probably August. Any later than that and your gerbera may not have a chance to fully mature. Starting your gerbera indoors is a great way to get them started a few weeks earlier.
