I have a small pond with a water falls. The weeds are growing in the rocks and impossible to control.I need a weed/grass killer that will not harm my fish in the pond. Tried just pulling them but it does not work . Also tried to burn them out but they come backstronger. Any suggestions on controlling the weeds/grass in the rock of my water falls?Most weed killers are toxic to fish so they cannot be used for my weed problem

    Call a pond store, I'm sure they have run into before.

    Here are some homemade weed killers you could try:

    Most commercial weedkillers pose some type of danger to fish. Make one yourself to stop weeds and keep anything that comes into contact with the pond natural and nontoxic. One method is to combine 1 teaspoon of liquid dish detergent with 1 tablespoon of gin, 1 tablespoon of apple cider vinegar and 1 quart of water, and spray the solution on weeds. Another weedkiller is made by combining 1 quart of vinegar with 4 ounces of lemon juice concentrate; spray the mixture on weeds. Use vinegar with a 20 percent concentration for the best results.

    I'm a pond owner so I might be able to help with some info. We use 100% hydrogen peroxide on string algae in an effort to keep the 'stream' clean, as well as suspended algae that collects in the rocks. This product changes soon after being exposed to oxygen? And will not harm our goldfish. I googled and a strong % application to weeds acts as a weed killer. I would think applying it during hot/warm weather would be of benefit. Hope this helps.
