Actually, when we have visitors, we often share gardening tips 
My raised beds have been great this year and we've added a second hand greenhouse (it was dh's dad's which we finally dismantled and brought over to our place).
I've been enjoying courgettes, potatoes, purple podded peas, French beans (will we still be allowed them
), runner beans, broad beans, curly kale (none of the other brassicas are ready yet), lettuce, garlic, cucumbers, raspberries, redcurrants, blackcurrants and radishes. The re-planted asparagus bed should do well next year, judging by the growth this year. The tomatoes in the greenhouse are only just starting to ripen - hopefully that will now accelerate now that the Rosella is turning pink. The Victoria plum tree is absolutely laden with a plethora of plums but none are quite ripe yet.
I should be fine for bartering in the even of empty supermarket shelves
(also have a good sourdough starter so can make bread and am already stockpiling flour
)
