Rotting compost slime on cement under wisteria pegola

I have a wisteria growing on a pergola outside my kitchen window. During the winter months all the leaves fall onto cement. When It rains it leaves the wet leaves wet and rotting, (and there lies the problem). No amount of elbow grease and constant brushing, raking, and even squeegee pushing has been able to eliminate the green slime that forms year after year. I have tried a bleach. Does anyone know how to kill off or drastically reduce this very slippery green slime. The problem is worsened because it receives no afternoon sun creating a dark and flourishing environment. This space is a heavy trafficked area.

Did you use straight bleach?

Try Coke or vinegar and baking soda

How about some coarse salt, like the kind used on ice in winter, or maybe ice cream salt? Scrub with it, then sweep it up and rinse. It works on slug slime, so maybe it will work on this!

You may be able to eliminate the majority of the slime-building before it starts by "catching" the leaves as they drop. Place a tarp under the wisteria, then "dump" the tarp daily until all the leaves have fallen. I know it would be troublesome for a week or two but may be worth keeping the space dry and safe for walking in the winter.

Sound like a good idea I will give it a try. I was thinking about caustic soda or draino (it unblocks drains) This problem is awful, After a hard squeegee session a couple of days ago and i little leaf drop then rain, It looks like nothing has ever been done to it. It almost appears to, excrete from the cement when it gets wet. Blah
