Late frosts can last surprisingly late, even into summer, depending on where you live. Determine your USDA Hardiness Zone for more info on what relates to your specific region. A garden in Minnesota in Hardiness Zone 2 or Zone 3 naturally has much later frosts than a garden in Florida or Georgia in Hardiness Zone 9 or Zone 8. By understanding the Hardiness Zone your garden grows in, you can better determine late frosts and also discover which plants can thrive in your environment. Of course, checking your local news and weather channel will also help.
Nonetheless, we think every garden should have Harvest Guard on hand because you’ll need it to protect against late frosts, and it also works to protect plants from bad summer weather like torrential rain and hailstorms!
