Growing seed potatoes in containers

Late summer/early autumn is the perfect time to plant second crop seed potatoes in containers so that you have a delicious crop to go with your Christmas Lunch.

These potatoes don’t need chitting and it takes about 12- 14 weeks from planting to harvesting. Charlotte is always a reliable and delicious choice. The size of your container will be determined by how many tubers you want to plant but use containers at least 12in wide with drainage holes in the base – you can also buy special potato growing containers.

They have to be grown in a frost free environment so you can start them outside and then put them in the greenhouse or sheltered spot if there is a danger of frost – remember to think of this when you choose your container size as the larger the container the heavier it will be to move!

Start by adding a layer of potting compost or a mixture of soil/compost 4 in thick for a 12 inch pot but if you use a larger container it can be half filled.

Then plant one to 3 tubers per pot (depending on pot size) with about 12in space and cover with 6in of compost or soil.

As the foliage develops earth the potatoes up with further compost or soil until the container is full to within 2in of the top.

Keep well-watered and feed with a general purpose fertiliser.

In late autumn the foliage will yellow and die down and can be removed and composted.

Just leave the tubers in the pot and keep fairly dry until Christmas and you want to harvest.
