What do I need to know about mulch?
I have premium brown mulch that I want to put on the soil below my tomatoes, any tips, ideas or anything I need to know before I do it?
Edit: Do I need to replace it after a period of time? Does it get diseases of fungi or stuff that can be harmful to my plants?
I added that it's brown mulch, does that work on tomato plants, and my vegetable bed.
