Tips Of Mandeville Be Leaves Black.

The tips of my Mandeville leaves are turning brown/black and spreading. Also all the new growth and flower buds are withering and dying. There are webs on the plant. I sprayed with Neem oil. Which seemed to work, before the week was up it started attacking the new growth. Should I just continue to treat with Neem oil?

Yes, follow label instructions but it usually takes more than one application. If that doesn't seem to work, try an insecticidal soap.
