I have a 10 year old potted Sago Palm. But since last few years whenever a new growth is about to produce new branches on the plant, it's been attacked by caterpillars and they eat away new tender growth. I tried Ganexine powder to control it but it's useless. Please advise me on any home remedies to ensure its new growth.
One more thing which I would like to add is that my plant is in a pot, medium sized. Should I move it to a larger one or is it ok with a medium size pot?
