How to prune Jostaberry?

Hi All,
I have a Jostaberry bush and would like to know the correct way to prune it. Any details is welcome.

Regards,
Thomas

It does depend on how old the jostaberry is. If it's less than 3 years old, I'd leave it alone apart from removing anything dead, damaged or diseased.
I treat mine mostly like blackcurrants, which means that a third of the oldest stems are cut down to the base each year in winter. They fruit on wood that grew the previous year or year before that. If you leave the stems to get older than about 4 years, they get leggy and don't produce as much fruit.

and the plants end up about 8' in each direction...

Chop wildly with a large axe in any direction, stamp on the remains, set light to the branches, flait at it with a chainsaw and it will still shoot in all directions and give you loads of fruit, including where the branches dropped and took root  ..............::) ;D

Only 8 ft?  ;D

Mine are as vigorous, for certain. Funny enough, there's a bush on someone else's land nearby here which isn't, keep meaning to get some cuttings to see how they do next to my existing ones.
