Nutgrass Control with Molasses

Liquid Molasses Controls Nutgrass

The best control for nutgrass appears to be molasses, believe it or not. Drench problem spots with

liquid horticultural molasses

at ¼ to ½ cup per gallon of water. Start with about a gallon of drench per 9 – 10 sq. ft. This simple technique fires up the microbes in the soil and the nutgrass simply fades away. It takes a while to work and requires at least 2 – 3 applications. As opposed to toxic chemicals, it makes the soil heathlier with every application.

product to speed up the process if turf and other good plants can be avoided. Physically removing the damaged weeds obviously also speeds up the process.

Before and After

And finally here’s an interesting report on using this technique.

You suggested that we use molasses to stop nutgrass. We tried it and it did not kill the nut grass. Thought I had made a mistake until I dug it up and low and behold — NO NUTS in the nutgrass. The molasses stopped the development of the nodes that stay in the ground when you pull up the plants. It worked! Just thought I would pass that discovery on!

M.A., Rowlett

Thanks very much for the report. That explains why it takes more than one application of the molasses to kill the tops.
