Knopper Galls
Posted: Wed Aug 13, 2008 10:52 am
Dear All,
Whilst out and about in Lymm, Warrington yesterday I happened across a small Oak tree alongside the canal that was literally covered in Knopper galls caused by the gall wasp (Andricus quercuscalicis).
When I say covered there literally was only one or two acorns WITHOUT Knopper galls on them. Can I ask does anyone know whether we are having a good year for them ? Was this just an unlucky tree ?
Cheers,
Eric
