What can I do to "save" my hisbiscus plant?

Question

I bought a hibiscus "tree" this summer, filled with beautiful flowers. Of course they are gone now, but the leaves of the plant are turning yellow and dropping off. Is this usual for the winter? Also I notice that the original pot it came in, may be too small. It's roots are showing on the top of the dirt. Any info you can give me would be greatly appreciated.

Answer 1

Check the bottom of the pot.  If there are roots coming out of the drain hole, repot.  It is a good idea to loosen any compacted roots when repotting.  Give them a drink of fertilizer.  

Heat and humidity encourage blooms (mine are still flowering).

Cuttings will root in water.

Answer 2

I am watching your answers as I want to save mine over the winter.  I am waiting to re-pot mine until just before the frost.

Answer 3

It's a clear sign the plant needs to be re-potted. The yellow leaves show nutrient deficiency. Re-plant in a bigger pot (Don't take any of the soil away from the roots!) and add little fertilizer. For the first few days keep the plant out of direct sunlight as it needs to un-stress from re-potting.

Also: with Hibiscus always be on the look-out for white mealy bugs. If you see leaves curling up before they grow to full size: spray with "Sevin" bug killer. You can find it at your local garden center.
