Care: Hibiscus love the sun and need moist, well-drained soil. Keeping these plants watered will result in larger flowers and lush foliage. Deadheading will improve the appearance of the plant, but is not necessary for continued bloom. It is best to plant Hibiscus in the garden before the heat of the summer arrives, and should be heavily mulched the first winter. In spring, cut back any remaining stems before new growth appears. Do not trim back in fall. A strong pair of loppers or a saw will be necessary to cut this plant back. Be advised that Hibiscus is always one of the last perennials to emerge in spring. Be patient, even if you think it is dead, it most likely isn't. Its vigorous growth rate more than makes up for this late start, however. Japanese beetles find these plants especially delicious. Fertilize with Proven Winners® Continuous Release Plant Food in spring and midsummer.
