Yes,Gattina..mainly for protection against frost..which you might not have now,but also to stop any potato's going green with the light,as they form..they need to be deep down..

I tried deep planting one year, against advice, and found that the potatoes took longer to develop and we did not get as great a crop as usual.

That's interesting, B & B, I wonder why it has that effect? I was just being lazy and trying to get out of doing some more work. No such luck!

I didn't have any problems with mine,Gattina..maybe 'my deep' isn't as deep as I made it seem..I dug in lots of homemade compost in th Autumn,then dug down to a spades depth to plant..bearing in mind,I only grew first and second earlies,salad potato's..as I didn't have space for later ones..they looked a lot deeper,by the time they had been earthed up.:o)..sorry if I misled you..you don't need to dig to Oz ! Lol.

I'm a very lazy gardener, Bloomer. They are already in at a depth of about 12". Unfortunately, our precious homemade compost has far too many bits of the garden to be spread over, but the soil itself is pretty good, having had years of well-rotted farmyard manure dug into it. The last lot was applied well over 2 years ago now, so I was hoping that it would be fit for potato planting. There's a lot of space, but rotating crops (there are a lot of those, too) becomes a bit of a challenge, year on year.

Sounds as though you will have some top notch spuds,Gattina..I agree about the rotating bit too..that's why I can't grow any more..I have tried them in pots,but the yield I got,wasn't worth the effort !...

Belt and braces, Bloomer, I have some salad potatoes growing in pots, too. We were told by some locals the other day that the "worms" that put holes into the potatoes we grew the first year we were here, came from the insanitary slurry our nearest neighbours had been putting on our land for the previous 12 years. We had, a few days before, taken delivery of a whole lorry-load of the stuff for rotting down over 2 years before we use it on the whole garden (root crops excepted). The smell out there is delightful (!), but it does get better. As the neighbours' son, Daniele, who had delivered it, wandered over this morning and said "You can hardly smell it now - just like cake!" All I can say is, it does seem to keep the deer out of the vegetable garden, and it's very good on the roses.
