Hello, new to the forum and as I have noticed I'm not the only one with a leave yellowing problem. I recently purchased a topiary Hibiscus(Fiesta) and transplanted it into a pot for the patio. The plant looked somewhat malnourished when purchased but here in the south with the heat all looked pretty rough. Anyway I have done all I know to stop the yellowing of the leaves ; watering more, less , sprayed for aphids, thrips,(no sign of any insect) have fertilized once, added kelp, but still they are yellowing from bottom up. Also leaves are curling up like a Taco. anyone with some insight on what to do is appreciated. Wx here is mid 90's, Im watering once per day at dusk. My bush hibiscus are healthy,just the tree is struggling
Installing a drip irrigation for the patio to keep a constant moist. Here is a pic of my Hibiscus

I concur. Moving it from the nursery to the patio and placing it in full sun with hot temperatures was probably a shock to the system. Then, you had some inconsistent watering and that probably started the leaf yellowing and curling. In the summer, acclimate the plants a little (keep them in bright shade, then in morning sun, then in some afternoon sun). Then try to be more consistent with the watering and make sure you water enough and make sure the drainage holes are working. The root system apparently is not developed enough to handle all this. See below for watering suggestions in order to make sure you are also watering enough.

PS - do not apply insecticides if you do not see the insects (but that is ok if you are applying the insecticide early due to infestations on the previous year). Foliage sometimes "reacts" to chemicals this way and worse.

All hibiscus probably yellow every once in a while. Too much water not enough water too hot. Could be a number of reasons. If its in a pot you should probably water it everyday.
