First of all the so-called "Ponytail Palm", Beaucarnea recurvata, is not a
palm but is instead a desert plant with a swollen bottle-shaped trunk
(pachycaul). Morning sun is not enough for the plant. Move it to a south or
west facing window instead. It will grow better in a more graveley soil mix
that drains quickly and does not stay moist. A constantly moist humusy soil
is bad for desert plants. Let the plants go dry between waterings. Also hold
back on the fertilizer. Quarter strength once a month is good enough.

(BTW, Beaucarnea is in the family Nolinaceae not the Agavaceae.)

om...
I've grown the two ponytail palms from seed. They are on the same
window sill (south-facing, but only gets direct morning sun due to
buildings in the way). The larger plant isn't doing very well. The
newer leaves are yellow and brownish, and it keeps getting worse. It
is potted in all-purpose potting soil (repotted less than 1 year ago)
which dries out between waterings.

I thought the issue might be lack of nutrients, although the sick
plant is in fresh soil (less than a year old) while the other has been
in the same smaller pot for about 3 years. I water them both with
Schultz all-purpose plant food. But the situation just keeps getting
worse.

If anyone has any idea what the problem might be, please email me. I
think I'm going to replace the potting soil.
