Seems to be an informed opinion?

I planted out my main-crop potatoes today. I did dig holes for them and gave them each some home made compost, recycling organic matter in situ. I do tend to dig but mainly because I don't keep on top of the weeds. The main one is probably grass which seems to seed all year round. I've not got round to the patch I grew onions in last year and it is now looking not much different from a lawn. I'll roughly dig it over just before planting out pumpkins and squash there with a bit of homemade fertilizer and compost.
