It's a very young sago, so if you want to give it a little bit of fertilizer, get some pelleted, time-release that is formulated specifically for palms, and give it a very small amount. Maybe about 1/4 of what the package recommends. This is because the plant is in a pot, and quite young. The fert won't dissipate as much in a pot as it would if the plant was in the ground.
Would you fill in your profile, so that we will see whereabouts you are? Gives us more info about your climate to help answer your questions better. Just city/state/country would be great. See mine in the upper right corner?
