We have a fairly large sago palm that is growing out of its pot. We really don't want it to get any bigger. Is it OK to root prune the palm and put it back in the same, shallow pot? The palm is about 10 years old and is a beautiful specimen. We keep it in the heated poolhouse in the winter; outdoors the rest of the year in Pasco, WA.

Remove the plant from the soil and wash the roots down with water. Then take a clean pair of shears or scissors and trim away the roots. Repot in clean, well-draining potting soil. This article should also help: https://www.gardeningknowhow.com/houseplants/hpgen/prune-roots.htm
