Blackberry white drupelet syndrome

Never heard of it! I haven't been blackberry picking.... I am not good in heat so I've been hiding away making jewellery...hoping I haven't missed them all.

Too early for the blackberries around the hdgerows here! I keep looking when I am walking Kato but only manage to forage what I call 'King fruits' which are usually the earliet and biggest on the bush. Maybe another couple of weeks before I get out with my tupperware!
