Plumbago Plants

About Plumbagos?

verry57 added on November 14, 2012 | Answered

I live in FL, zone 9. Why do my plumbagos have dark brown leaves in the joints of the branches? How often should I fertilize? I have very sandy soil but put rocks in the bottom of the hole before I planted and use black cow fertilizer on the surface and every 30 days or so use Miracle Gro. Is that right?

The dark leaves could be natural coloration, if the leaves are supple and healthy otherwise. If they are dried out, then it might be a fungus. A standard fungicide will treat that.

As far as the fertilizer, the Black Kow is fine every month. If you are using Miracle Gro, I would do it once every 2-3 months as it is a bit more potent.
