Braided Hibiscus care

Question

My red braided Hibiscus tree (it is a container)is blooming very well but it has started having yellow leaves. I used a systemic insecticide on it in the spring and do not see any kind of insect on the tree at all. I did start using Miricle grow bloom enhancer in the water once a week. It has been a very hot summer here in NC and I have had to water it daily or the new leaves start to wilt.I have read a lot online and there seems to be many different opinions on how to care for the tree. Any suggestions about what to do?
I also have another braided Hibiscus that bloomed well last year but has not bloomed this year at all. I took it in during the winter and followed all the recommendations for care. I also started using the bloom enhancer on the one once a week too and I finally have some buds appearing although not many. I do love these braided trees but feel as if I have 2 young children that require a lot of care. Anything you can suggest would be most appreciated. Thanks so much, Brenda
