I have grown potatoes in sacks for the last few years but the harvest is nothing to write home about - do you think I should feed them - or will that just make more foliage instead of potatoes. n.b. There is plenty of garden compost mixed in with the potting compost.
Specialist organic potato fertiliser made a difference to my sack potatoes last year but this year I am just growing outside, using organic seaweed meal at planting. Try liquid seaweed Magicrop.
Elaine, when I mix my potting compost I add a good sprinkle of BFB and then feed the spuds with a commercial tomato fertilizer once the tops get to a decent size. I supplement this with my own seaweed feed.
This year I'm also experimenting with a commercial slow release potato fertilizer added at planting time. Results will be published when crop is lifted.
I didn't know you could get a fertilizer specifically for tatties - you live and learn.
Elaine..you can use home made seaweed or nettle liquid feeds, no need to buy!!
yep I agree with Jan. It works for me
The only real advantage of the commercial pelleted feed over home-made is that it is slower release. As long as you don't mind feeding every week with nettle tea, etc. you should get similar results. I have about 70 containers of spuds so it takes a lot of feed.
70? Are you insane!
That's the nicest thing anybody's said to me all week!!
We get through a lot of potatoes in our house.
Are they all in containers or do you grow in the ground as well - which crop better for you?
All in containers which vary from flower buckets through polypots to fish boxes and an old wheelbarrow. Yields per square yard/metre used are actually higher than growing in the open ground which is why I dispensed with the daft idea of growing veg in rows several years ago.
