I did this once with D. auriculata when I was growing seeds in an old
(homemade) tool "tray" - it was the only large sized tray I had at the time...
I used a gold-panning sieve to sift out the tubers - even then it was hard
work and somehow many still managed to escape! If you want to risk it, you
can carefully dig down around escaped peltata plants following the main shoot
from the rosette down to the tuber which can then be carefully lifted up
hopefully still attached and repotted. I wouldn't recommend this procedure
be used on your main plants or during the time when the plants are approaching
dormancy when they tend to produce "droppers" for the new tubers.
