Is is just that the gulf stream is stuck at the moment making our weather weird. Last year I grew a great set of muscles draging water up and down the lotty and some days it was too hot to work.
I know what you mean Sandy, this wet weather is playing havoc with my bingo wings this year
I just believe in working with nature as much as possible. Use mulches to slow down weed growth, remove grass paths if you struggle to keep on top of cutting. Put up wind protection on an exposed site, cover plants with cloches or net, use raised beds f your soil is cold clay to provide more drainage and allow the soil to warm up faster. Put a pond in the end of your plot that floods in winter rather than cursing every year when it drowns your plants (I realise this year people have faced exceptional problems - but I mean a plot that has issues every winter).
You also have to learn lessons from your experiences. When my plants showed signs of poor pollination, I installed HM bug hotels and planted flowers to encourage the pollinators. When my pak choi got ravaged by pigeons, I netted them the next time. When I had to pull up a load of my brassicas when cabbage white infested them, I invested in some environmesh and built cloches, etc. When I lost all my early courgettes one year because I planted them out too early, I had to sow some more - so now I grow mine on into the largest pots I can and plant them out when I am really sure the frost has passed.
And, sadly, you also have to admit when you simply can't grow certain things on your plot. Many fellow plot-holders don't grow onions because of the white rot issue, some don't grow potatoes any more because of blight. I grow salads at home mainly and not at the plot to avoid flea beetle.
I still grow onions, despite my plot suffering with white rot because I like to try different approaches to lessen its impact - but I then don't cry into my watering can when I have to throw affected ones out.
Sometimes, I think some gardeners are guilty of thinking they can work against nature - you are on a road to nowhere on this one. Of course, there are also years when nothing seems to work and has others have said, you just resign yourself to it being one of those years and then you reach for the seed catalogue for inspiration for next year!
