The guy is correct in that it isn't a palm, but a cycad. Some people treat them more like succulents and cacti because of their tolerance for dry conditions, but it is best to water them regularly. It probably doesn't need to be repotted, because they don't have huge root systems, and they grow very slowly as well. However, I would remove the glued-together rocks from the top of the soil.

They like full sun, but make sure to acclimate it first to outdoor sunlight if that's where you plan to keep it. Otherwise, it will get sunburn and the leaflets will turn brown.

Cycads grow in "flushes" where all the leaves come out at once, not one by one. So if it isn't growing, don't worry. Eventually, it will flush a new set of leaves.

Not sure what else I'm leaving out...Good luck with your new sago. Don't expect it to double in size any time in the near future though...that could take years.

Thank you so much for your help, islandbreeze.
