Here in central Ohio, the wild raspberries usually start ripening the same time as the Mulberries do. The Mulberries have been ripening for over a week and the raspberries are no where near ripening. In fact they are only about 1/2 grown. Hopefully they will continue to grow and get nice and fat and juicy before they ripen! We have been getting rain at least once a week or more, so everything is growing like crazy! If they ever ripen I will post a pic of them!
I've noticed that my raspberries, tayberries and strawberries are very slow this year - only just in flower now. The blackcurrants and gooseberries are fine though and ripening as I type.
I checked our raspberry patch. Nothing so far. But getting rain about every 2 days. Need a week of nothing But Sunshine and warm winds.
Our reds aren't ready until about the first of July and the blacks usually follow that, but we took our row of black ones out last Fall and didn't replace them....yet and maybe never so I can't say for sure if I notice anything unusual this year.
