Potatoes in containers

Last years potato crop was extremely poor, and the few potatoes raised were mostly kept back for planting this year. This years crop has been very good, despite the dry summer and I have plenty safely stored away.

However last year I had quite a number of small potatoes which weren't worth cooking and really didn't merit being planted in the potato patch. What to do?

Normally I'll boil them up and feed them to the hens, but by the spring some of these had gone rather green.

At the beginning of the year I usually plant a few salad varieties for raising in the polytunnel for an early crop. These are planted in tubs and I use the compost out of containers planted in the previous summer to save cost. The fertility of the compost can be easily raised with the addition of suitable fertiliser. Usually these are harvested from early May and then the containers are vacant. (See  "Early Potatoes" February 2012)

This year I decided to reuse these containers and plant them up with these small green potatoes. I had plenty of compost to use out of the compost bins and it was an easy enough job to fill up the containers, set them on a piece of ground which I wasn't using, and plant in the potatoes. After that they got only the occasional watering.

Today I emptied them out. Yes, they should have been done earlier, and they have been on the list of jobs to do, but other things have got in the way. The compost was tipped out onto the potato patch and I was very pleasantly surprised by the quantity and quality of the crop. A good size, few blemishes, hardly any are green and with a quick hose down they are good enough to take to the kitchen.

Most are salad varieties but one is a good second early potato with a deep red skin, 'Maxine', a variety I haven't been able to get easily any more, so I'll keep that back for planting next year. Certainly the salad crop will make a pleasant change from the main crop which we are eating at present.

The other benefit has been the number and size of the earthworms that have been living in the containers. Many were probably small worms or eggs when they were emptied from the compost bin. They have now gone into the potato patch for the winter.

Was it worth doing? Yes, if you have suitable containers - they don't need to be very big, up to 40cm tall is deep enough, and a supply of compost. They were no trouble to keep over the summer and easily harvested. The crop was good for the size of the tubers that were planted. Main crop potatoes would not be the most suitable variety to use, unless you wanted to bulk up a few tubers for seed potatoes. Definitely worth doing if you've got an excess of small green potatoes and don't know what else to do with them.
