Hi everybody,
I am wanting to repot my hardy water lilies. This is the 3rd summer in this pot but it is a very large pot. They are in an aquatic gravel type soil now but I have a problem with algae bloom when I fertilize them. I planted them that way to keep from getting that stinky rancid soil that I have found when I bought some pond plants. Also I thought they could get their nutrients from the water plus help filter the water better planted in the gravel stuff. I have since learned that they need more fertilizer than that. How do I plant them in a clay mix and keep it from turning stinky? I think I read somewhere that using Osmocote with the gravel will not cause a algae bloom, is this right? Also, I would like to add some liquid iron to the water to help all the plants. Could someone tell me what type to get. I don't know if it matters but our water is pretty hard with ph around 9 and about 3000 gals with 7 comets, a dozen or so rosys, and a few frogs,
Thanks,
michelle
