Last year was my first in the U.K.. After many trips back and forth I arrived for the duration on May 23rd.
My husband had hired an individual to start the kitchen garden (my earlier visits were dedicated to clearing ground and ridding the property of debris mounds...you couldn't walk through the kitchen garden upon our initial arrival).
This gentleman did a wonderful job of making sure the garden was in progress when I arrived and through the help of the local garden centres we managed to have quite a successful first year.
...then I heard about "Club Root" and other problems. I met an individual in our village who has a magnificant garden and cannot grow brassicas. He stated to me that he believed that he brought the problem in through a purchase of a plant from a garden centre. I then learned that our neighbor, also a very accomplished gardener, had this problem, and also a problem with his raspberries that he believed was due to his purchase of new stock.
I made a decision that all plants, outside of our seed potatoes, would come from seed grown with one brand of compost. I emptied our greenhouse, sterilized it, and also sterilized all pots on the property before they could be used for new plantings.
My quandry is that there are times when purchasing from a centre would be more convenient...leeks and tomatoes (I'm short of both this year) being an issue.
The space I have to work with is large.. (my first post in my personal Garden Diary gives an overview of the kitchen garden situation..
http://chat.allotment-garden.org/index.php?topic=57855.msg679776 ) and I'm willing to keep working from seed...but I'm truly looking for insight from U.K. gardeners who have lived, ate and breathed this environment for years...Am I being too protective and should I relax a little or just keep going according to my plan?
