There's another way to 'encourage' them to grow plantlets; <g>
I posted a few weeks ago about a sword that I'd prematurely divided. Ripped
it right in half; one part got all the roots, the other just got a chunk of
the crown.
The part without roots did just great. It's happily sent off new roots, and
is sending up new leaves like crazy.
The other chunk, however, seemed to just deteriorate. The leaves got
yellow; it didn't seem to be sending off any new leaves; finally, I pulled
it up from the back of the tank to look at it. It had seven new plantlets
at the root!
I stuck them all in a newly set up planted tank, and in a week, they've
doubled in size (from about 3 inches tall, to 6 inches or so). Thank
goodness the PVAS auction is next week... !
