It's probably pot bound and may be too wet. Unfortunately sometimes when you buy those little plants with the rocks or sand glued to the top of the pot the plant may already be dead underneath. I'd get it out of that pot and have a look at the roots. If they are still healthy, you will want to put your plant into a gritty, fast draining soil, gravel, sand mixture. Cheryl

Thanks Cheryl for your help. I'll remove it from the pot and have a look. I was surprised that the stones were actually glued on. When I bought it I thought it was just a layer for decorative purposes.

I took the sago out of the pot Cheryl and I'm surprised it lasted as long as it did. Some of the glue had gone down into the soil and it was like a rock. The roots were very dry so I removed all the rock hard soil put it in new fast draining and will now wait and see if it was too late or if it will bouce back.

Thanks again.
