planting corn and watermelons

Question

When is it too late to plant corn and watermelons in south GA?

Answer 1

In a warmer climate such as yours, you can get by with late planting as you have a longer growing season. That said, you would have to water more since planting this late in the season, or even July, will mean summer's brutal heat on young, tender plantings. So if you are intending to grow these crops, I would certainly get them started now. Here is growing information on each: https://www.gardeningknowhow.com/edible/vegetables/corn/grow-sweet-corn.htm
