I am caring for a palm for my daughter in law and would like to repot it. It is a parlour palm. I have had it for 2 + years and she had it for 7 yrs prior to that. It is happy in my east window as it constantly is getting its flowers (seed fronds). However each of the stalks have quite a bit of lean to the plant and I would like to plant it deeper. Is this possible or would I harm or kill it if I put it in the soil deeper?
