Oooh, Ash, I'm so pleased to have a fellow raised bedder!
This year I grew runner beans and climbing french beans (not in the raised bed though) I prepared the trench according to instructions with well rotten manure and newspaper and I had a very good crop of both, enough to eat and to freeze some too. I grew both from plants bought at the garden centre.
I planted cabbage seedlings and had a fantastic crop of cabbages, really big and heavy and very tasty. My tomatoes were useless as were my courgettes which usually grow like topsy, carrots were bad this year but last year were fantastic. Broad beans were planted from seed and didn't do any good at all. Last year had lots of shallots, didn't grow any this year. I put grit round the beans to deter slugs and cover the cabbage and cauliflower with netting to stop butterflies and am vigilant about picking off slugs. (More OH than me to be honest!)
So as you can see it has been very hit and miss for me. I would like to raise more from seed, having the greenhouse means this should be possible, but I haven't got to grips with when to plant etc. Maybe we could share seeds?
I have Carol Klein's book too and lots of other gardening books so I should be able to produce a fair amount of produce. It will be great to work together via the forum and give each other ideas and encouragement.
