J, never thought of using tires for that. I have plenty of those! I have the same problem...agriculture land. We have cattle, they must have access to the pond, surrounding land gets litter for fertilizer also. I noticed after the FA dies off during the cooler months I got a GREAT bloom. I have limed, probably need to again as we live in a very acidic area.

Not trying to highjack, thanks for the idea!

J and Dono, do you have trouble with your potted plants during heavy rain events?? Do you use some kind of burlap, peat, or netting to keep the soil in place?

Pondfun, we haven't met, so WELCOME!! you are in a great place!
