I thought most salad crops in winter were grown under cover in Spain and Morocco so not affected by the weather? Even if they were it’s hardly surprising that with EU grown crops, EU countries get first dibs.

Also British greenhouse growers haven’t been able to afford to heat their greenhouses.

I remember when I were a lass there were no tomatoes, cucumbers etc in the shops in winter. Salads were made with raw winter veg eg coleslaw. Remember making winter salad in cookery class at school. 

The other day on LBC radio the topic was discussed and thoroughly nailed. A wholesaler at Nine Elms (New Covent Garden Market) explained how it was only indirectly affected by Brexit. When there is plenty of produce about, it makes sense to sell to the UK that won't pay a decent price. When bad weather causes a shortage they are naturally going to sell it within Europe as a priority where they get a better price.

UK farmers are being squeezed out of the loop because the supermarkets won't pay enough to give the farmers a decent living and now that farmers are not receiving the subsidies they used to get from Brussels they are scaling down or quitting altogether. Bottom line appears to be that until UK shoppers are prepared to pay more for their food there will be wide fluctuations in supply and price.

The shops are empty here of veg like the above mentioned and more, and the press are saying its like that all over Europe, lying to us all still, just as long as they never print, IT'S BECAUSE OF BREXIT, I asked people in our village in France, and the shops are still full of all of the above as they usually are, Hook Line and Sinker we've been done...... Even Northern Ireland is not being affected.........

I managed to get Potatoes and onions and garlic today.......

We are back out to France in 2 weeks

Much though we all want to blame Brexit, I do not believe the problem is there. Nor do I think it is the EU looking after its own. Traders will sell to whomsoever pays the best price.

Morocco has suffered abnormally large snowfall and Southern Spain has also suffered bad weather, so there is less out-of-season vegetables available in Norther Europe. But is is available - unlike it seems in the UK. The prices here have gone up a great deal however. Small boxes of cherry toms were 99c a few weeks ago and are now 2.99€. There I think lies the problem. UK supermarket purchasing managers are just not prepared to pay the price required. No doubt their year end bonuses demand that they keep purchase prices below set levels and they are not prepared to lose their extra cash just to keep the customer happy.

I saw nothing in that article that can be laid at the doors of Brexit. Where the criticism comes is from a lack of government action or support post Brexit - but that is not Brexit per-se that is the problem. It is the government that is the problem.

I cannot ever remember where I bought a set of ladders a few years ago when someone asked where I got them. 

exile is right it has everything to do with Brexit.   it is worth a read.
