Overwintering Tropical Hibiscus - Knowledgebase Question

Pittsburgh, PA
Question by hess02

I am making my first attempt in overwintering a tropical hibiscus. Initially, my plant looked dead and then I noticed a few green leafs sprouting from the trunk of the plant. I put it under a plant light.

2 questions: How much water does this plant need and how many hours a day should it be kept under a plant light? Any other suggestions would be appreciated.
Thank you in advance.

You should be successful with your tropical hibiscus indoors if you keep the light on 14-16 hours a day, water when the soil begins to dry out and withhold fertilizer until it goes back outdoors next spring. When it is outside and actively blooming, you can keep the soil consistently moist (but not soggy wet) and feed every 2-3 weeks with a half=strength dilution of water soluable fertilizer (such as Miracid, Peter's or Schult'z). While your plant is indoors it will need less water and no fertilizer because the growth will be slower than when it's outdoors. Hope this sheds some light on your project!
