Growing Grub
Here in France we suffer a lot with doryphores (Colorado Beetle). For the last few years I have grown my potatoes in straw which does seem to have reduced the number of beetles I've had to put up with.
1) A week or so before planting time (or, if you want to try and conserve water do this in winter), break open a few bales of straw and lay the wedges - tightly together - over your spud patch.
2) Soak for several days until saturated. (if doing over winter then forget this stage. The rain will do it for you)
3) Lay seed spuds over the soaked wedges and cover with loose straw. As the spuds grow just "earth up" with more loose straw
4) From time to time check the bottom is still damp. Water if required. I find that I rarely have to water
5)To harvest, or if you want just a few New Spuds, lift the loose straw and take what is wanted.
6) After all the spuds have been harvested you can either leave the straw in situ and re-use next year, dig it into the ground or move to a manure/compost heap to finish rotting down.
Sorry I haven't got any pics. I didn't think of taking any as I've used this method for a few years and I've also broken my camera when I had a fall.
