Clivias Covered in Caterpillars
I have one Clivia that is covered with caterpillars. I have trimmed it right down and have sprayed it with the Margaret Rose mixture. Do I need to spray again and, if so, how often? Do I need to add any form of fertiliser? The other Clivias do not have any caterpillars, but I will keep an eye on them.

I would spray about once a week for one month just to make sure you clear the pests out. I would not fertilize until you see the plant putting out new growth. Stressed plants can be easily burned by fertilizer, so it is best to wait for it to recover before doing that.
