Slimy Fungus on gravel

    This problem showed on a tarmac path at an elderly relatives home this year a few days after I had sprayed with a moss killer.  It died away but with the rain this week has come back with a vengeance. It has also spread to a small area which has astroturf.   The astoturf was laid 3 years ago on top of an old carpet in an effort to kill ground elder and has never had a problem before.  The area is alluvial soil in a chalk valley so the ph will be alkaline. 

    I will try the suggested treatments one by one starting with acidifying though I don't want to take the colour out of the astroturf.

    To all those who think astroturf has no place in a garden I would agree but the relative is 95 & it gives her a safe place to potter and tend raised planters.

  • Thank you for all the feed back from Bill Hall, Cob Cottb, Parker 0482 and others. Yes it is apparently called Nostoc Commune or Star Jelly and is a bacteria. I last wrote 11th March and YES my driveway is still clear. I have since seen 2 neighbour in the past week with it, one outside her front wall on the pavement, the other in his back garden between brick paving, both had used Round Up, it seems this could be the cause.  I've also had another problem, I had to cut down a rotting apple tree last year so I saved a section about 3ft high and put it in the front garden with plants growing out the holes left by the cut off Branches. About 2 weeks ago, after loads of rain, 100's of tiny toadstools appeared  covering an area 2-3 feet wide around the trunk, after a quick panic I made up my soda mix and in 24hours they had disappeared, so far the plants around the trunk look fine. I hope you are all having the same success with good old soda and can't wait to hear.

    Thank you plant pauper for directing me to this thread. Husband online just now ordering soda crystals. Fingers crossed ?

  • My father has the same problem after using roundup on his gravel driveway here in West Kerry, Ireland. Roundup must change the ph level in the soil then, he too said he never had it before spraying roundup and he's lived here for a very long time. We're going to try the washing soda solution.  A very interesting thread with what seems to be a simple and non toxic solution, wonderful! :) 

  • I cannot believe the great and practically instant results I have had using swimming pool PH Decreaser.

    i just scattered over the gunk as the rains started and voila, gunk is dead!

    Just noticed this slimey green plant on our gravel. It's been exceptionally wet this winter /spring. Husband has been spraying with round up so Will try the soda carbonate. Hope it works. Thank goodness for this site.

    Thanks for this discussion on the slim.  I too have used Round up and as a result have this terrible slippery slime covering my gravel driveway.  I'm thrilled to see that the Dri-Pak Soda Crystals work but wasn't sure how to apply to resolve the problem.  Could someone elaborate on whether you can just sprinkle on or do I need to make a solution and what would the best recipe for the solution?

    Also I see these Soda Crystals are located in England.  Does anyone know if there is an equivalent product here in the US?

    Thanks again!

    This may help Judy:

    Look for 'soda ash' or 'sodium carbonate'.  If you can't find any, the link above tells you how to turn baking soda (widely available anywhere) into it.

    A trowel in the hand is worth a thousand lost under a bush.

    Thanks Bob for the great link!  Any idea how exactly it should be applied?  Could I just sprinkle it on?

  • Hi from Australia, hey lucky us; we have it too! I have a clay based soil, covered in crushed rock. We had never had this slimy mess until a few months ago. I always weeded by hand but one day I went out and my husband had sprayed the weeds that were coming up through the gravel. This slimy mess appeared but I did not relate it until now. Two days ago I had relaid new gravel over the top of the old thinking this would save the slime returning. We had 40mm of rain in the 2 hours following and within a day the slime had returned. Wow, amazing (said with a lint of sarcasm)!. Anyway I have read these posts with interest this morning and will go and do what I need to do. Thanks
