I can tell you from experience that gooseberries are fond of walnut trees,
and so I would suspect by extension all ribes.
The gooseberries have formed an inpenetrable phylanx around two walnut
saplings. Every year I mean to fight my way through and cut down those
saplings and
subjugate the gooseberries. Like the 300 Spartans they have withstood all
attacks. Worthy opponents, they.
