Caroline I sympathise! There is a saying that growing vegetables is months of hard work followed by frequent disappointment which, although you may well agree with at the moment, isn't always true on reflection.
I get an immense amount of pleasure from my allotment on many levels especially as I don't have a garden, and I certainly don't have it just for the production of food. I have little sense of taste yet my own vegetables do taste different, if not better, but perhaps that's as much in the mind as anything. I always have the inevitiable ups and downs but at the end of the day I wouldn't want to not have a plot.
Gardeners have to optimistic otherwise we wouldn't bother to get out of the armchair, and as we always say...
there's always next year!
PS Grow early potatoes to avoid the slugs! I've not lifted my Desiree which I'll be doing during the week with a certain amount of trepidiation now, although here in London it's been a dry hot summer and relatively slug free.
I'm new here so don't know where everybody lives , but this summer has been particularly wet up here and this has helped increase the slug population by quite a few percent, so maincrops are suffering more than usual. I have grown all sorts of spuds this year and best were the Hhighland Burgundies and Edzell Blues, both for harvest and cleanliness. Not sure if the red / purple skins on these varieties played any small part in this though - will see how my Roosters fare this weekend. I am not going to be growing nearly so much veg next year as I just do not have the time to commit to it, and have decided to grow my tatties in polypots - so will see if helps alleviate problems with slugs too.
