Hibiscus spp.

In cool, moderate areas, you can grow hibiscus and the rose of Sharon.They can survive in conditions between 60 and 90 degrees Fahrenheit and can withstand temperatures as low as 20 degrees. When the temperature drops below 30 degrees Fahrenheit and there is a danger of frost, bring container-grown plants inside.

Feed plants with a high potassium and high nitrogen fertilizer to promote plentiful, robust blooms with vibrant color. Organic fertilizers include seaweed extract and fish emulsion. Just before the bloom period begins, feed a half-strength solution, and keep doing so for at least a few weeks until flowering is finished.

Once established, hardy hibiscus benefits from annual winter pruning. After flowering, prune the plant back to maintain a neat appearance and to remove any dead, diseased, or broken branches or old wood that has grown in the middle of the plant. If you forcefully trim back, don't worry; this species can withstand it.

It is safe to have hibiscus plants around kids, toddlers, and newborns because neither the leaves nor the blossoms of the hibiscus plant are toxic to humans. Hibiscus sabdariffa's calyxes, leaves, and flowers are all edible. The calyxes are the main component of hibiscus tea, a tart beverage packed with vitamin C.
