A few posts back, someone asked about SuperThrive. A friend just brought me some from the States and I used it, as directed, on almost all my tropicals, including DR's and hibiscus. Whether it was that, or just a lucky combination of sun, rain and mild temps, I don't know, but things are blooming like crazy. I Googled SuperThrive and no one seems to know exactly what's in it, other than "vitamins and minerals." It seems to work best on plants that are not exactly thriving.
