PLACEMENT & CULTIVATION
Sunset hibiscus is a stunning flowering plant that not only adds beauty to your garden but also attracts butterflies and bees. It's versatile and can be grown in large containers on the patio or used in the mid to back border of a garden. The plant's seed pods are also eye-catching, covered with silky hairs that shine when backlit. Native to Southeast Asia, sunset hibiscus is related to the okra plant and is a common ingredient in Asian cuisines, including its leaves and flower buds. This tropical plant thrives in hot and humid climates, but surprisingly, it can also grow quickly and flower reliably in northern gardens.
Keep evenly moist, but not soggy.
Prefers neutral but will tolerate slightly acidic to slightly alkaline
Fertilize every couple of weeks with an organically sourced water-soluble fertilizer.
Diseases & Pests:
Place in an area with good circulation to prevent powdery mildew and rust. If such issues do arise, plants can be sprayed with an organic fungicide. If slugs are a problem, treat the surrounding soil with pelletized iron phosphate.
