Every year we grow some Potatoes in bags. A few inches of compost in the bottom of a sack, holes in bag to allow drainage, pop in 3 or 4 Potatoes per bag, cover with compost and there you have it. The ones above are Sarpo Mira. They were topped up with compost twice as they grew. They were not treated for blight and only now are they getting some spots on leaves.
They were harvested last week and as you can see there were lots of lovely little pink potatoes to be gathered. We emptied the bags into the wheelbarrow for easy access.
This lot is from one bag which contained 3 seed Potatoes. The Potatoes are small but I do find the bags don’t produce big Spuds.
This is the total from the 4 bags, a little over 10 lbs. Not bad for very little effort, delicious little organic Potatoes from our own garden.
The resulting barrowload of compost was used to top up one of the veg beds. I love little garden experiments like this, it proves you can grow spuds anywhere even without a garden.
In the long border this pink Astible is blooming,
and outside the polytunnel this container of Cosmos continues to provide colour. I love Cosmos and will save seeds from these for next years crop.

I’ve just done the same! After last year’s rain I’ve already planted four and have two more lots to go. One is and experiment with green new potatoes of the anya type from the supermarket. I’m going to see what they do. Experiments are such fun, aren’t they?
What a wonderful idea, I’m going to share this with my sister, she doesn’t have much for outdoor gardening space but could easily fit a couple bags like these. Thanks!
Looks like a fun thing to try. Thanks for the great idea!
Great post. I didn’t know you could grow plants in bags. Amazing!
Well that was seriously brilliant potato growing. I will definitely try this next spring. Thanks for the awesome idea!
Growing pots in bags seems to be getting more popular, must admit I do like big ones for baked pots and wedges/chips/fries.

I love cosmos and planted them this year after winning seeds, but the wet spring damped them off. I am glad to enjoy them in your garden. I am impressed with your nice crop of potatoes. I can imagine all the ways they will be cooked.
