Last growing season I started no dig and having watched numerous permaculture youtube clips I did a straw mulch over all my fruit and veg plots. As Charles says I had a huge slug problem especially on potatoes, I hardly had any undamaged spuds.
The straw doesn’t rot down in one season either so I have now had to rake it all off and put it into the compost heap.
The only successful use of straw was on my soft fruit beds as a weed supressing method but I still used well rotted muck first, I’m not sure I’ll add any more straw this year if I can get hold of some well rotted muck instead.
