The other day someone asked me about tay berries. They are a cross between a blackberry and a raspberry. We only have one bush grown on wires at the end of our raspberries. I am trying to train the branches diagonally. to encourage extra shoots. This is its second summer.
You have to wait for the berries to go a deep red otherwise they are a bit tart. So far the birds have not shown any interest, preferring to nibble the raspberries further along.
On the other side of the tay berry are two cultivated blackberries - they are full of flowers and young fruit and have made much better progress.
