I so wish I could grow water lilies. I know part of it is that I don't plant them well. Pots are not big enough or have the right soil. I have a 33 gallon garbage can half full of plain garden soil that I was using to plant mine in. Then got derailed into using pea gravel since I make such a mess out of introducing the pots to the pond. Need to put them in a large sterlite container to settle down and get the soil really wet, THEN put it in the pond. Also a problem in that my pond has a very uneven floor and setting up cinder blocks for the pots to sit on is a problem. I don't think I can just sit the pots on the bottom as the plants would have to grow at least 18" to get to the surface. Stupid question, but wouldn't they 'drown' without CO2 access? It would surely be easier than trying to set up stands.
