Answer: Hibiscus trees will grow to a height of 6-8'. You?re going to get the most flowers and best growth by placing your Hibiscus in full sun. Try to keep the plants out of windy areas. The plants will thrive outdoors where the night temperature normally doesn?t drop below 50 degrees. Hibiscus are used outdoors in tropical climates for landscape. Avoid excessive cold and hot areas.
It is important that you keep the soil of the Hibiscus moist at all times. Saturate the soil at each watering. To test and see if you need to water, place your fingers on the top of the soil; if it feels dry to the touch it is time to water your Hibiscus. Water your plant at least 3 to 4 times a week (outside). Don?t allow the plant to sit in standing or puddled water.
Hibiscus respond well to normal house plant fertilizers. Trim the branches to maintain the desired shape.
Hibiscus flowers open daily and last for only one day, after which they die. Your plants will probably have flowers that have opened during transit and have fallen off and started to rot. This is normal. Simply remove all wilted or unsightly flowers and keep grooming daily.
Aphids can occasionally attack new growth, look at some of the insecticidal soaps as an option to control them.
Good luck with your new plants!
