Since coleus are not cold tolerant it's important to wait until after the last frost when the weather gets warmer before you can plant them.

The last month that you can plant coleus and expect a good harvest is probably August. If you wait any later than that and your coleus may not have a chance to fully mature. If you are starting your coleus indoors then you might be able to get away with starting them a little bit earlier.
