Q.Disease on Rosemary Plant
The small rosemary tree that I bought in December is dying off. It was in a tiny plastic pot, so I repotted it in a nice terracotta pot. I noticed a growth on the stems and branches resembling little brown knobby bits. Do I need to spray it with something?

It sounds like scale is on the plant, though it could be a few different pests. Rosemary plants tend to be hard to grow indoors and are very susceptible to pests. I recommend spraying it with neem oil. Here is some more information to help you:
