I’m curious how this works out for you.I had to order a new pump for my pond. The last one shorted out and kept popping the GFI. One the new pump gets here I need to drain the pond and refill it with fresh water. Normally this would be just a Fall activity, but since the old pump stopped working properly the pond has gotten nasty.
All that said, I'm thinking about pumping the dirty water over the garden. It's adjacent to the pond. I used to do this when there were just fish in the pond. With my ducks having access to the pond it gets muckier and I'm dealing with a different firm of waste. The garden is pretty dormant right now also... but I'm don't want to over fertilize potentially and ruin the soil for Spring - especially with all the planning I'm doing. Any reason I shouldn't put the pond water on the garden?
I’m planning to use my ducks pool water for an existing garden but the plants are mature. I too would be more concerned with microbes but can you turn the soil a few times and maybe water it down a time or two to help that?
