Dusty from Tx Water Lilies says it is no chance of hybrid or tropical lilies spreading too much. In fact, he said if put in a container, they will not grow to near their full potential. I did put mine in containers with a mix of clay and bank sand,to start getting them established. Should be ready to set in pond edge by June when it will be down about 2 ft. From there I will start with well water to keep level hopefully stabilized 2 ft. over the lilies.
Now if you plant lotus, all bets are off.
Dont see how an inch or 2 of bentonite would negatively effect the lilies as their roots will spread out and down.
