It’s important to know your garden zone so that you can plant the best varieties that will thrive in your area. Perennial hibiscus do best in zones 5-9 (21 degrees F/-1 degrees C at coldest), but tropical hibiscus need warmer temperatures (flower best at 60-90 degrees F/16-32 degrees C). If you live in a hot climate, hibiscus foliage will stay green and lush year-round. The flowers might take a break, but you’ll still have the vibrant leaves. However, if you live in a colder climate, the plant could die down into the ground like other perennials do. In that case, this article says you’ll want to cut the plant to about six inches above the ground to encourage re-growth when the weather warms up again.

2. Plant Your Hibiscus

Depending on your garden zone, you’ll want to choose your hibiscus variety accordingly. As far as hardy perennial hibiscus go, you’ll want to choose your location carefully, as the plant does not transplant well. Pick a spot that receives full sun and has rich, well-draining soil.

3. Keep Moist In Summer, Dry-ish In Winter

Keep your hibiscus well-hydrated in the summertime with moist soil. You’ll likely need to water daily for your flowers will to bloom in July and August. Keep in mind that these flowers might not last very long, but there are always new ones sprouting! As winter rolls around, make sure the soil is not soggy, and to protect your plant from a late spring frost, add mulch.

4. Fertilize Well

Some plants do not enjoy too much fertilizer. Hibiscus, however, is not one of those plants. Perennial hibiscus is a heavy feeder, so feel free to feed your flowers fertilizer rich with potassium and/or phosphorus. The main key here is that you should only fertilize during the summer when the blooms are budding. Your hibiscus does not need fertilizer in the winter, and it can actually burn the roots if it sits in the soil while your plant is dormant.

5. Give Your Hibiscus Friends!

Once you’ve got your beautiful hibiscus growing, give her some friends.Other flowers that go well with hibiscus are somewhat dependent upon the colour of your hibiscus. After all, you want an array of shades! For example, low-maintenance perennials such as Geranium Rozanne are great additions for hibiscus that don’t share their blue-violet hue.
