Hi All

I've recently taken over a garden, and discovered a few raspberries
growing among the undergrowth. The canes have been neglected, are
surrounded by rampant weeds, and produced a very meagre crop last year.

Will I be able to restore them to productive use by clearing away the
weeds, feeding, pruning, whatever else I have to do, or is the only
sensible thing to dig them up and plant new ones?

Any tips on the best way to do the preferred one of those options?

Thanks

Adam
