Q.Cycad palm
I have a cycad palm. I purchased it and found it had bugs. Treated that, but in the meantime, the palms started to turn yellow and fall off. I still have the bottom part of the plant. Can I get that to grow and, if so, how? I have kept watering it in the hopes of it coming back.

If the base is firm, it is likely still alive and could recover.
Reduce the watering and only water when the the soil is dry.
Here is a link to refresh you on the care requirements.
