The genus hibiscus contains over 200 different species of flowering plants which are native to temperate and tropical regions around the world. The hibiscus genus includes both annuals and perennials, as well as shrubs and trees. They produce large, trumpet-shaped flowers that can be white, pink, red, orange, yellow or purple in color. Hibiscus plants require proper climate control, feeding and watering to grow and bloom successfully.
Plant hibiscus during either spring or fall and in a location that receives six to eight hours of direct sunlight each day. Use a potting soil made up of two parts garden soil, two parts peat moss and one part vermiculite.
Keep hibiscus plants in a location that receives constant temperatures between 65 and 75 degrees Fahrenheit. Any exposure to lower temperatures can cause the buds to drop or fail to form altogether. Use a thermometer to ensure the temperature stays within this range.
Water hibiscus three to four times per week, enough to keep the soil consistently moist, but not soggy. Never allow the soil to dry out completely, or the plant will wilt. Apply water to the hibiscus from the top to soak all of the soil, ensuring all roots come in contact with moisture.
Feed hibiscus plants using a balanced 20-20-20 NPK fertilizer once every three to four weeks. Dilute the fertilizer to half strength prior to applying by mixing with water. Reduce fertilizing to once every two months during winter.
Prune away any growth that is unattractive or unkempt to maintain a smaller plant with thicker foliage. Pinch off dead or dying flowers to encourage the growth of more blossoms and to prevent the production of seed.
