I find that my prayer plants like to be in smaller pots and Im adding pictures of mine and they are two yrs old that I know of . I took the smaller one off the other one and it did just fine . I have a neighbor who is a farmer and she gave me the bigger one off her plant that was at least ten yrs old and she told me that the plant likes to be root bound or pot bound should I say . anyways here are pics of mine . I never put them outside .
