Slimy Fungus on gravel

  • We had been fighting the green slime of nostoc on our gravel driveway for a number of years with no success.  We tried every kind of weed killer and moss killer.  We tried copper sulfate, lime, and straight bleach.  We tried burning it off.  We even resorted to spray paint to try to sufficate it.  Nothing worked until.......  baking soda.  We just got bags of baking soda (bicarbonate of soda) from the local feed store and spread it on the driveway using a drop spreader.  We put a heavy coat on because we have no idea of the concentration level needed.   Within a week the nostoc turned brown - which from experience we know is the "dead" color.  The cripsy black color is just a "waiting to be rehydrated" color.  We are going to play with the concentration and see if dissolving the baking soda in water and spraying will have the same effect - but for now we are happy with the results.

    Hope this helps someone else.  We felt we were fighting a losing battle to the slime!

    I want to make a suggestion and I believe I am right, Have any of you use round-up on your drive to get rid of weeds? I believe that there is a direct correlation between the Round-Up and the Blue Green Algae.

    I am very sure where this stuff started from and I would like for you to just think about it. Have you ever used Round-Up or a product that is similar to kill weeds on your driveway? I believe that is what started our Blue Green Algae problem. Something to think about!

    Have you tried using Jeyes fluid neat? That is quite good at killing algae.

    What about vinegar??  Just a thought.....

  • Wondering if jchventures has an update? I would love to know if the baking soda remedy is still holding as effective?

    Hi rlkatz, I used RoundUp only a month ago and now I have this Blue Green Algae, you may have a point here as I never had this before using Round Up.
