Caring for your Hibiscus

Hibiscus (hy-BIS-kus)


A hibiscus plant will last for decades, producing papery blooms over a period of months each year.  Blooms, however, will last no more than two days.  Despite its showiness, hibiscus is one of the most reliable indoor flowering plants.

Light: Place in high light (southern exposure) in winter and medium (bright indirect) light the rest of the year.  Place outdoors in summer.

Water:   Keep soil uniformly moist, especially during bloom.  Raise humidity.  High humidity and moist soil are necessary to keep buds from dropping.

Temperature:     Maintain average temperature.  Avoid all drafts.

Comments:      Prune back ruthlessly after flowering.  May be summer or winter bloomer, depending on induced dormant period.  Induce dormancy by watering less and stopping feedings.  Feed every week during active growth.  Propagate by seed or tip cuttings from new growth.

Here are some additional tip on Hibiscus trees.

They are pretty susceptible to aphids.  We would recommend that you get a systemic insecticide and use it according to the directions.  We have them in our stores, or you can also get them anywhere that sells plants & fertilizer & the like.

Just before you bring it back into the building in the fall, as a deterrent to various insects, you should spray the plant with a mixture of 2/3 cup rubbing alcohol and 1/3 cup water.  This will also stop the plant blooming and makes it a good time to prune the plant back (see Comments).

The plant will want a spot with a lot of light when it goes inside.  South or west is good and be sure to avoid drafts.
