Andy,

When I move my ponytail palm out for the summer I have to prop it between other large pots or lean it next to a tree so it doesn't get blown over (much). The occasional storm usually topples lots of houseplants including potted trees, banana tree, and bamboo (22 inch pots).

This is what you call root bound. One of my bamboos ('Robert Young' is less than 3 years old) pulled out of an 18" pot ready to be planted into a 22" pot.
