A dear friend of mine gave me a cutting off her HUGE and prolific plant about 1.5 years ago. Around the same time, I believe I brought some insects in with some bad potting soil. I have sprayed with Bayer Natria Insect, disease & mite control as well as another Bayer insect killer. After I treat, I usually find dead insects around the plant which look like fruit flies. The plant seems to put out new growth but looks wilted.
