We have a 30-year-old grapevine that climbs around the dining-room
window. In all those 30 years it has never produced anything edible, but
we like the shape of the leaves, so have left it. This year, for the
first time ever, we had a huge harvest of grapes. We picked most, but
left those hanging prettily from above the window - and for the last
three weeks or so the we have had red admirals almost non-stop on the
grapes. They seem to be licking them.... I am glad they are finding
something before their awesome journey across the Channel, and maybe
across the Mediterranean - I just hope they aren't leaving it too late!
