I live near the coast in Los Angeles County, CA. I planted a one-gallon hibiscus about three months ago and it seemed to be doing fine.The weather has started to warm and the leaves are no longer dark green. They're a yellowish green with some of the older leaves becoming yellow along the edges. It has some new growth and a few flowers. I suspected the problem is over-watering due to heavy rain but the soil has dried out and things haven't improved. What's wrong?
Unfortunately yellow leaves can be a sign of any number of problems. Overwatering is always a prime suspect, so you're right to be thinking that way. How long has it been since the heavy rain? The plant might just need more time to recover. Another common culprit is nutrient deficiency. If you haven't fed your hibiscus yet this spring, try doing so now. That should help if it's lacking in nutrients, and if it's trying to recover from waterlogged roots, it can't hurt either.

I have several red hibiscus (do know the actual variety) that are about 2 to 3 feet high. I do not have a green house and really not enough room indoors to store them in the winter. I live in the Birmingham, Al area. Is there a good way to protect them outdoors when the weather approaches freezing?

I have a tropical hibiscus plant that I brought in over the winter. It has been healthy up until this past week. It has little yellow things growing up from the root. Is this a fungus or disease and would I be better off disposing of it and getting a new one?
It could be just a mushroom or fungi in the soil.

Is it normal for the tip of the plant to look like it was cut after the bloom has fallen off. even other tips without blooms look like they have been cut off and they have a white color to them also
Yes, the flowers drop off after 24 hours and sometimes can appear that they were cut.
