Eye-catching and distinctly tropical in appearance, plants from the Hibiscus genus are cultivated in temperate and tropical regions throughout the world. The tubular, brightly colored flower is well-recognized as an icon of Hawaii, and the flower is recognized as the national flower of both South Korea and Malaysia.
Hibiscus plants love full sunlight. Plant your hibiscus in a location where the plant will have a full day of sun. Well-drained soil is preferable for most hibiscus species. Swamp species such as the scarlet hibiscus (Hibiscus coccineus) and the halberdleaf marshmallow (Hibiscus laeviswill), however, will tolerate temporary flooding and poorly drained soils. These species may be planted near a pond edge or other moist areas of the garden.
Hibiscus plants can be planted any time of the year except winter. After you have a selected a site to plant your hibiscus, dig a hole about the depth of the plant's root ball and twice as wide. Place the plant in the hole, filling the hole with dirt about halfway. Water thoroughly before filling up the rest of the hole with soil, and then water again. If planting multiple hibiscuses, give at least 3 to 6 feet between each plant to prevent overcrowding.
Hibiscus plants are fairly low maintenance, but they should be given fertilizer frequently (twice a month) during warm months. Hibiscus plants can be pruned to keep the shrub looking fresh and healthy. Hibiscuses don't have many pests, but as with many plants, they are susceptible to aphids and white flies, so check the plant occasionally for holes in the leaves or the presence of small bugs. Keep the soil moist, especially during hot summer months.
