Worst year I can remember................

............in the 53 years since we came north to Cumbria
Just to list a few:
Out of 15 tomato plants in my greenhouse, I've dumped 8 due to blight
My late crop of broad beans are flat on the ground with canes and twine blown over due to last night's gales
Ditto my Runner and French beans
Birds beat me to my currant bushes
Again due to last night's gales, half my apple crop from six trees are on the ground and unripened

It has certainly been a weird year weather-wise 

I can remember a few others, so don't think it is anything new, climate-wise.... just a PITA!!

It's been a mixed year here.

Things that liked the wet and cool e.g. peas/sugarsnaps were amazing, but generally I'm getting a small harvest on each visit but nothing like the glut I would be expecting by now except in blackberries.

There are some unexpected surprises like my 3rd proper size aubergine so far off 1 plant (don't ask about the rest!) and the sweetcorn looks good (and tastes it!)

I’d endorse your view it’s been a tough year.
My beetroot didn’t really get going and my beans have been destroyed by slugs.
Fingers crossed my tomatoes at the plot ripen along with some other late sowing  and planting. Mind you just had a very tasty sweet corn cob hopefully next weeks promised sunshine will ripen a few more.

Yes, I've only had my allotment for 15 years but it's easily been the worst, by an order of magnitude.

I start the vast majority of my plants in module trays of 60 and I so I have far too many plants when it comes to actually planting them out. But even so, out of 40 brassicas I planted in early April I got 3 cabbages from. My entire June planting of lettuce and endives got eaten twice, that's over 80 plants with nothing to show for it. For my squash I planted over 20 plants, just for them to be eaten over and over, I have four plants remaining. The courgettes have produced two from over eight plants planted and eaten by slugs, only three survive but it's too cold for them to produce. My redcurrants produced nothing for some reason, same with the plum which hasn't produced anything for two years now.

Some things have worked, for example I've never had so many weeds as I have this year
 It's extraordinary how they grow so well, but perhaps understandable as it simply hasn't been dry enough to hoe for 14 months now.

The potatoes did well, blueberries did well, for some reason outside tomatoes have done well!!! Leeks look good, later plantings of brassicas have loved the wet cool weather so I should have loads of sprouts and PSB. Beetroot has done well. Still potential for the celeriac to do good as well. So it's not all doom and gloom. I should probably face charges in the Hague for the number of slugs I've killed but there are mitigating circumstances 

A couple of members mentioned rhubarb. Despite all the other failures I've got the best crop ever. Must be all the rain plus the fact that slugs leave it alone

Yes. Many bean seeds rotted in the ground or in their propagators, about 90% lost early on, cold/soggy. Everything went in late. Seeds germinated and were then instantly dried so died. Discovered a good wheeze with beetroot seeds:- pin down black pallet wrap over the rows, this keeps the soil from drying out and the germinating seeds being fried. As soon as any seedlings appear, remove the pallet wrap and water as normal, or they'll go all leggy.

Slugs have not been to bad a pest here. The new form of slug  pellets (e.g. Sluxx HP (approved for organic farming operations)) is excellent, apart from the fact that jackdaws seem to like them (a few deposits of blue jackdaw droppings by/on fence posts). I hope they get gizzard-ache, of course they're unharmed by pasta and ferric phosphate.
