The leaves of the my Aloysia plant developed brown spots. Initially I thought they were tiny insects, so I washed the leaves and indeed some of the spots were removed, but other spots could not be removed. The brown spots look and feel like dry leaves in the autumn.
I cut all the branches with the leaves with brown spots, and a day or two later, I noticed tiny sprouts of fresh clean leaves starting to grow. Now my questions are:
- Are these brown spots only a sign of old age, so that the new leaves will be OK? Or, are they a sign of some illness that might infect the new leaves?
- What can I do with all the branches that I cut, with the brown-spotted leaves? After washing them well, can I use them for tea?
