Handbags (The sad, the bad and the ugly. Non-productive stuff here.)
ayrefield - one of the drawbacks of growing potatoes in sacks is that you never get as many as when you grow in the ground - this is often due to watering - a few of mine didn't have enough water this year. Did you grow new potatoes (often called earlies - these grow quickest)? Someone gave me a great tip this year - instead of emptying the growbag out when the potatoes have flowered - stick your hand in and have a feel - if they are the size you want then take a few but leave the plant and bag as they are - apparently you can do this several times and you get more of a crop - I don't think the compost matters but they need a feed or rotted muck in the bottom.
ps - I never buy peat-based compost now - as we need the peat bogs for the environment. The coconut fibre, I find, is in most forms of compost now - especially organic ones - I also come across a lot of conker shells.
