;) mulch from leaves dont work, too short period to downgrade, too big risk for pests and parasites or mold/fungus to have perfect conditions. Thats my view. Science on my side too ;))
I believe that sick or dying plants create sounds/waves which attracks all worries even more to them. I noticed with my outdoors plants, if one is struggling, thats the one who will have all diseases, rest is perfect ...
But untill you try yourself, its hard to hear others.
Have fun !
