I've not grown any veg, but my plants are struggling too. Perhaps it was the very hot weather that we had earlier in the year during lockdown, that might have caused nature to get a bit confused.
Noticed far less snails than usual too.
Out in my garden today and mowed and edged both lawns and general tidy up. Although the plants I got from Homebase a few months ago has helped, my gardens are still lacking that big splash of summer colour that you would expect at this time of year.
