I read somewhere that the caffeine in coffee is actually a self defense mechanism against disease in coffee plants and that some people actually spray coffee on there plants to prevent disease.

 

In the past year or two I have built up beneficial mycorrhizal fungi under my baby apple trees with wood chips and leaf mulch. Then recently I secured a source of free coffee grounds from a local convenience store to use as mulch. I am wondering if there is any chance the coffee grounds could kill off the fungi under my trees. Should I reserve the grounds for other uses or am I just paranoid about the effects of grounds on my fungi.

 

Any input appreciated,

Jim
