I brought my hibiscus plant indoor for the cool temperatures and the buds have a brown spore dots on them. I do see small ant like insects crawling around the base. How can I kill these bugs??
It is possible to grow some eucalyptus species in a pot, but they do grow quickly, so they are not the best to keep indoors long-term. It would eventually need to be transplanted outside or given away. I am not sure what species you have, so I am not sure whether it would survive in Massachusetts.
There are people who make bonsai eucalyptus, but that is something you would need to consult an expert about. There may be a bonsai club or society in your area that could help you.
Perhaps drying the foliage would be the best solution?
