#MARAZKA The tropical hibiscus (Hibiscus rosa-sinensis) is an evergreen plant with large, vibrant flowers that bloom from summer to fall. It thrives in USDA zones 10-11 but is usually grown in pots since it can't withstand temperatures below 30F. With proper care, it remains healthy and produces abundant blooms. Soil and Site Tropical hibiscus requires well-drained, moist soil. For outdoor planting, enrich the soil with compost and ensure a pH near 6.8. In pots, use a potting mix for tropical plants and ensure the pot has drainage holes. The plant needs full sunlight, with some afternoon shade in hot climates. Water and Fertilizer The plant prefers evenly moist soil. Water potted hibiscus when the top half-inch of soil is dry and empty any excess water from the drainage tray. Outdoor plants need about 1-2 inches of water weekly, more during droughts. Both potted and garden hibiscus benefit from monthly fertilization in spring and summer with a fertilizer designed for tropical plants. Winter Care If temperatures drop below 50F, bring potted hibiscus indoors near a sunny window. Some leaf drop is normal; if the plant drops all its leaves, reduce watering but keep the soil slightly moist. Resume normal care when new growth appears. Both indoor and outdoor plants go semi-dormant in winter and only need watering when the soil feels dry. Mulch around outdoor plants to protect them from cold spells.
