Answer: There in Whetstone you rarely get freezing temperatures and rarely get any snow so I wouldn't worry too much about frost. If you're growing tropical or sub-tropical plants such as hibiscus, you might want to cover your plants overnight if the weatherman predicts a freeze. Otherwise, everything should be okay.
Gourds grow just like squash - they're planted in the spring and they mature at the end of the summer. Seeds are usually available in the springtime at most garden centers and grocery stores.
Best wishes with your garden!
