Most hibiscus plants are of the tropical variety- they’ll want lots of sun and may not be able to survive freezing temperatures.

When attempting to grow hibiscus in zone 9, you’ll want to get the hardy hibiscus. These cultivars are cold-tolerant enough that they can survive a frost or two with little help from you. You can also get the tender varieties, but then you will have to bring them in to protect them from winter.

Regardless of variety, most hibiscus plants will thrive in full sun and soil that’s well-draining. You can put them in containers or the ground, and don’t forget to water on a schedule to keep the soil moist. The plant can get sunburned when they come into contact with afternoon sun, so it’s best to put them in a location where they get partial shade.

It’s recommended that you fertilize your hibiscus to get the most blooms.
