August 23rd – I don’t know what it is in the season, but the acorns this year are prolific and absolutely huge. With the dry summer I’d have expected the opposite, but they are absolutely huge. 

The fecundity of the crop is, however, being affected by the large amount of knopper galls, that from from acorns attacked by the knopper wasp. Also a peculiar seasonal phenomenon, they are very,. very red this year, whereas it’s usually just tinges of colour. 

Wonder why?
