We have mentioned the problem we have with tropical waterlily
overgrowth in Repotting
Overgrown Tropicals but this one is a slightly different
case. Our Nymphaea 'Smoulder' grew toward the center of
the pond and needed to be moved back to the edge. Like most hybrids
of N. ampla, 'Smoulder' tends to grow somewhat sideways.
The shovel is at one end of the one-year growth rhizome, the
crown at the other.
With a sharp knife we cut the huge rhizome
near the crown
and removed it.
We dug up and floated the plant back toward the edge of the pond.
The shovel is again included for scale.
'Smoulder' is safely reinstalled in the sand bottom,
anchored with rocks.
