RE: Potatoes - how deep? - Vinny - 24-01-2021
The only reason I earth up is if frost is forecast, and then it can't really be classed as earthing up because I only cover up any leaves that are showing with grass cuttings if I have any or soil if I haven't. I think earthing up CAUSES more green potatoes as they push out the side of the mound.
If it wasn't frosty my spuds would just be grown on the flat in an 8 to 10 inch hole planted using a bulb planter and some used compost added.

I just plant a little deeper, never really understood the concept of earthing up

In the same way tomatoes will root on the stem if it is buried, so will potatoes. Potatoes form on underground stems. Earthing up (or planting deep) increases the length of stem underground, so increases the opportunity for potatoes to develop. It must increase the yield or farmers would not use expensive ridge making machines when planting spuds. Planting extra deep is OK, but the plant has to use much more energy before leaves reach the surface and replace the energy used.

As far as I am concerned the jury is out? No-diggers seem to manage OK.

Local farms dont ridge here, so as mentioned, horses for courses

We all seem to have slightly different ways to grow spuds!! Fascinating.

It would be a bit boring if everyone gardened the same way.

Planting deeper would have the same effect as earthing up. It can increase the yield by lengthening the underground stem which the potatoes grow from. It may help some varieties more as some seem to bunch close to the stems while others grow more spread out.
If the seed is on the small size and planted 11" or a foot down, it may be knackered when it eventually reaches the light. It may be better still plant a foot down but leave it in a bit of a dip so only has to grow 4" before the light. Then fill in as it grows stronger.

I assume you are using the same variety of potato, I know probably a stupid question!

Yes Danny the same variety will be used and in all the same type of bucket, after I had posted about trying this I remembered something that Veggie had mentioned in the past about reading a book about a lady who used bales of hay or straw to grow her potatoes can't remember her name it's Stour or Stout or something similar so hope paper might do the same
