Not all plants can survive frost or the onset of the cold season when winter comes. Plants that are rated hardy in zones 8 to 10 are most likely to die when you plant them in zones 6 or 7. This means they won’t be able to stick around and grow when spring arrives.

Having the right type of plants eliminates frustration of having to start over every growing season. Aside from knowing which zone you’re in, it’s best to do some research on the kind of plants that can grow in your climate.

For those who are planning to start a garden outdoors then you’ll have to follow the planting zone and get plants that can live in your zone.
