What do you mean by closed pots ? Tell me more. Howard


I have my lilies is plastic dishpans.
Every year or 2 I lift them out of the pond and divide them.
I stick plant tabs or jobs fertilizer sticks in the dirt
all around the roots.
I cover the dirt with egg size river rock to keep the fish
from digging in the dirt and I've never had trouble with
algae blooms from the fertilizer.
This has worked well for me for 5 years.

I know some folks plant their lilies bare root on the
bottom and just anchor them in place with rocks or bricks.
I don't know how they fertilize!

Peace!
