Green Potatoes

Hi,  Some of my seed potatoes that are in trays chitting are turning green, is this a problem and should I dump the green ones or just leave them as they are??. Any advice please.

Err   

You need to put them where it is dark all the time and light can't get to them.

I thought you chitted them in the light, that's where mine are............i'm really confused now.

I wouldn't worry about going green or soft, as long as the 'soft' is the drying out kind of soft not mushy soft. (And they're not looking like they're dead from dehydration! )
Chitting in the light will produce shorter chits. I have seen some seriously straggly chits on potatoes kept really dark so I think there's a happy medium to be had.  :happy:

 
I'm not an expert, though!
I chit mine in the dark because I always put them in a bag in the garage and forget about them!
nothing deliberate. 
But it seems to work - the chits are usually about 1/2 an inch when I put them in the ground and nice and fat.

I think I heard someone say that they put them on the windowsill for a day or so before they go in the ground.

Oh, now I've confused myself!
   

Potatoes chitted in the light, as they should be, will always turn green. They are perfectly OK.

You should start chitting about 6 weeks before you intend to plant. If the potatoes show no signs of sprouting bring them into a warm and light place for about a week to wake them up and break their dormancy. Once you can see chits growing move them to a cool and light place until planting time. The light will stop them from growing long chits.

If they start to get a bit soft and wrinkled some people spray them with water or dilute foliar feed. Personally I do not bother. They only usually get wrinkled if they are in dry central heated houses. Move them somewhere cooler.

Mine are in garage on a bench [light] and in the house.

when they chit, the have more than one shoot. I recall from when i was very young, my stepdad use to cut the seed potatoes in half to plant more out...he then trimmed any other shoots off so only 1 shoot per section being planted.  Is this the correct thing to do

Because he cut up the potato, his yield per 'seed' was less and could not support a lot of top growth, so he was correct in what he did. But if you plant a whole spud intact, there's no reason to trim the top shoots. In fact, you'd get more spuds by not trimming it on an uncut spud.
