Growing Tatties in a bin query

[Bravehearted]

I am growing four maincrop potatoes in my old plastic bin. I planted them with four inches of soil below them and have been adding soil from time to time to cover the green foliage. When should I stop covering the plants?. The soil level is up to about two foot now. I have also another variety growing in a black bag soil level on them is about six inches above the tuber.
Any advice would be appreciated.

Come on guys, I posted this question over an hour ago. There must be at least one Potato gowing NERD out there! Prove me right!!

If you see potatoes starting to come through the soil cover them if not they will
go green

keep adding soil everytime the shoots come through till you are at the top of the container. This will give the longest underground stems and the most spuds.

Thanks Woofgang consider it done. Manjo I knew about the green tatty thingy but I'm a bit aways from harvesting.

the other sting spuds need is plenty of water.
