I received this plant from my daughter who recently purchased a home; the former owner left her all her houseplants including 3 pots of Madagascar Palm. This specimen is leaning precariously; too shallow of a pot and not heavy enough I believe. I plan to repot it but my question is can I plant it deeper so that the soil reaches the green and thicker portion of the stem. Note the narrow portion of stem that is above the soil at present. Can I bury that thin portion of the stem? This is not a type of plant I am familiar with so appreciate any advice.
