Thanks. I've actually had reasonable success with cherry tomatoes and herbs this year and have actually vowed to set up one of the composters we have again so there will be a supply of compost from next year.
For the tomatoes, I grew these in old flower buckets, which you can buy from Morrisons for 99 p for 6-8, depending on how generous they are feeling so I'll have a go at that again. I might also use the buckets for herbs as I think they do benefit from a larger pot too - these sit on a little patio just outside the kitchen door, although obviously might not work over winter.
So next year, I'll do the tomatoes again and I might have a go at potatoes in one of the buckets, just to see how it works, I could probably get a pound or two of baby potatoes, so it's just for fun really, rather than a serious food production/money saving exercise.
I know what you mean by just spending a few minutes each day keeping up with things, but it's difficult when you work long days and have other things to do, I found myself resenting the time it took to pot things on, or needing to water on a morning, because I hadn't done it the night before and if they were left any longer, they probably wouldn't survive a day in the sun.
