If the mulch was in a wet pile or a plastic bag that got hot before it was spread, that can encourage fungus spores to grow. Also its best not to have mulch more than a few inches thick if you don't want stuff to grow in it. Is there a way to know if you are allergic to this or not? It is probably a mushroom, and may not affect you the same way as household mold. It could be if it was just broken up and spread around a little bit it would go away. Most fungus that grows on mulch isn't harmful as long as you don't eat it, but I don't know the extent of your alleries. I occassionally get fungus in the mulch on my property after alot of rain, but it usually doesn't last. Could you check with your doctor to find out if you are also allergic to this type of thing? Good Luck,

try spraying it with a bleach and water mix first to kill the mold. then the guys could dig it up with out worry of spreading it. best of luck with it and hope this helps.

I often get fungus in my mulch. I just stir it around a bit, and it seems to go away. I am allergic to household mold as well.

Be Safe, Rach

Thanks all for your input. If I did spray it with bleach and water would that kill the Rotadendrum(sp) it is underneath of? I probably don't have to worry about it but it looks worse now that it turned black than it did when it was white and would love to KILL it but not kill my bushes.

Thanks again. Anyone, please let me know if spraying it with bleach would harm the plant also.

Hi there~

Actually, spraying around your plant won't hurt the plant as long as you don't spray a ton of it. It will spot the leaves if you get the bleach on them though, so just be careful to spray on a still day. I have found that the mold will turn black and go away on it own once the mulch dries out a bit, so you may just want to turn it a little to aerate it and leave it alone. I've never had moldy mulch kill anything. Good luck!
