Happy New Year!
I do it and it works wonderfully for my tomatoes. I don't actually use it for peppers, but I should think they would love it too!
I also bought some red plastic (on sale) at Canadian Tire. The strips happened to fit my garden perfectly, but is rather skinny, so I have to put some newspapers under it, otherwise weeds still grow! It works fine as mulch.
I have noticed that the areas covered in black or red plastic seem to work better than the adjoining areas which are covered in a thick layer of pond weed. So there you are.
