Hardy means strong, bold, or capable of prevailing through tough conditions. If it wouldn’t make sense to replace hardy with strong or bold, then you probably want hearty, whose main meanings are (1) expressed warmly, (2) providing abundant nourishment, and (3) unequivocal.
Think of hardy as related to hard, and hearty as related to heart. Things that are hardy are strong and hard, while things that are hearty often come from the heart, warm the heart, or give heart. It might also help to remember that hardy often describes people, while hearty usually describes inanimate things. There are exceptions, though.
These distinctions extend to all derivative words, including hardier, heartier, hardiest, heartiest, hardily, and heartily.
