What is wrong with my hibiscus?

Before the bloom could open, they fall off. There must be something wrong with what I'mdoing.

Reply:Hibiscus plants need A LOT of sunlight. If it was outside during the summer, and had to be brought inside, this will usually send it into a little bit of shock. I use grow lights for the season change, then the plant doesn't go into shock. Also, they require plenty of water.

Take a look there and they should have an answer for you.

Reply:It could be a number of things - thrips, too little or too much water, little or too much fertilizer, gall midge, too much heat.
Reply:Let 'em dry out a bit (just a bit). Hibiscus don't like "wet feet".





Also, many so-called hibiscus fertilizers are horrible for hibiscus (way too high on the phosphate). Try a tomato fertilizer or dig some Osmocote into the soil. A low middle number (7-2-7 or so) is a pretty good route.





Also, how long have these plants been in the same pots? They may be root bound, in which case you can root prune (trim a bit of the root ball all the way around, and do normal root bound procedures to encourage new roots) or simply pot up. For hibiscus potting soil, I mix regular potting soil with perlite, bark, and some cactus soil if I can find it -- also a little potting charcoal if I've got it. That makes a very well draining soil.
