I'm seeking advise on how to bring our raspberries back into a disciplined
way of fruiting.

They have been allowed to go untended for a few years and now, end of
April,
are full of new green shoots.

If last year is anything to go by fruit will be few and far between.
Raspberries are like blackberies, they fruit on year old wood. Start on by
pruning them back to maybe four canes per crown. Pull out many of the
offshoot plants. Once this is done you can train them with tomato
cages...After you cut into them hard feed them with some 10-10-10.
