i have had a plant a friend's mom gave to me, a spiky slow grower for a year and never knew what it was. cruising google i discovered i have a pony tail palm, a very young one, with no trunk to speak of but coming straight out the bulb. it has green shoots coming from the top, and maybe looks to have about 6 growth spurts as the leaves are arranged from the bulb. the fully grown trees look gorgeous and all my other plants are growing new shoots every day. i just repotted it into a larger pot, with rich loam/peat and a drainage dish. my apt is semi-humid and anywhere from 67 to 73 degrees F. how do i make this thing grow?
