I want to move a plant of the above berry which obviously needs to be against a wall with netting to climb over rather than the tomato cages that I supplied.

Trouble is, the plant in question has sent out canes 5m long at least but has never fruited [it was planted nearly 18 months ago now and faces west]. All my research suggests I cannot cut back any cane which hasn’t fruited but I think it would be unwise to attempt to move it as is.

I have a raspberry and a boysenberry with an identical issue. All three plants have new growth around the base but have sent out very long canes.

Do I take a chance and cut back these hugely long shoots – I don’t want to have a third summer with no fruit. If so, do I remove completely or just cut back – leaving how much – and when can this be done? Also, when is the best time to move?

Hi Carol, I think you are being too kind to your plants – too much food! I wonder if this has resulted in vegetative growth than flower and fruit growth. I would apply only one of your fertilisers in spring – say flower and fruit fertiliser.

You may have had dry berry which can attack the flowers and therefore no fruit formed. This is to do with the weather we have experienced this season. I would suggest you cut back on feed for spring.
Prune back in winter and burn all pruned and waste material.
If you think that there has never been any flowers, then it would be too much vegetative growth.

As you say best not to cut back hard, but I would recommend that you reduce the canes to 1.5m or similar, for moving. I presume that you have studied the pruning notes on Floricanes & Primocanes.
Do this cutting back once the plants are fully deciduous )without leaves

Thanks the Palmers Team
