Dichondra are barely cold tolerant which tells us that you can plant them slightly earlier than other frost tender plants.

The last month that you can plant dichondra and expect a good harvest is probably August. You probably don't want to wait any later than that or else your dichondra may not have a chance to really do well. Starting your dichondra indoors is a great way to get them started a few weeks earlier.
