I have a large sword plant in my tank that has produced a long stalk with a
baby plant at the top near the top of my tank. It has no roots
yet...question is do I wait for roots to form to remove it and plant? My web
research seems to indicate that I need to wait for roots to form. The baby
has 8 to 10 nice 2" leaves at this point.

The most dependable way is to bury the base of the baby in your substrate. Roots
will form within days. If it is too hard to snake the long stalk back down to
the gravel, Just be patient, roots will probably form eventually.
