Growing Potatoes In Compost Bags

This season I am going to try growing three early red potato plants in compost bags. I have seen this done on Jamie At Home a while back and then saw it again on Down on the Allotment. I thought I would give them a try this year so I can have some red potatoes. Here is how I went about planting them:

First I sprouted some early red potatoes from last years garden.
I was lucky to find these lingering in the crisper, they are a little
small but they should amount to something.

I started the planting by jabbing some holes
in a typical sized bag of top soil for drainage.

I then cut the bag open, removed & stored half the soil and rolled
the top down. I then stuck the seed potato into the bag and topped
that will a few inches of soil.

I then grouped them together in the new lower bed I am putting in
for potted potatoes & tomatoes as well as herb, rhubarb and sunflowers.

Now my only concern is light penetrating the bags and turning the potatoes green. By the time they start growing I will have double bagged them into black plastic bags to stop the risk of having green potatoes.

Once the plants grow about 6" I will roll the bag up, fill it with the remaining soil to replicate hilling and hopefully harvest some early reds in July. If this approach works well I will start them early in the poly tunnel next year for an extra early crop.
