Ponds "They do have significant maintenance needs, so if you are avoiding growing things hoping for simplicity, other options may be better." LOL. I loved our garden pond but I had to dredge it daily from all the rocks being tossed into them, not leaving much room for the fish. Maintenance was better after I upgraded the filter. But the fish couldn't keep up with eating the mosquito larvae. Still, I miss the pond.
I did this. My suggestion would be to add cardboard or something up the sides to hold water. My garden did SO WELL, but it dried out easily. Also, in the individual holes, I planted herbs, green peppers and zucchini. They did excellent also!! - Garden Ideas
