I have a beautiful yellow Hibiscus-- not sure exactly the variety but the attached image is of one of its blooms. Right now my biggest problem is the fact that its completely infested with little black bugs (possibly aphids?). Last summer it bloomed a few times but the flowers fell off as soon as they were completely opened, it seemed. Now it blooms halfway and the bugs take over the blossom and kill it. I can also show an image of one of the infested unopened buds, but I can't seem to figure out a way to attach more than one image to this post.
Anyway, now one or two of the leaves are starting to yellow, and I'm curious if there's a way to eliminate this problem, and/or something I can do to ensure that this summer, the plant flourishes. I'm in the middle/end of a chilly winter season so I don't expect even indoors that the hibiscus will be at its prime until the spring, but I'd like to know ahead of time what I can do to prep it for a fruitful and beautiful summer blooming season.
Any help is appreciated!
