2021 - What I did today

My raspberries are not the healthiest but as they give me more fruit than I can cope with, I've not bothered to do much with them.  Most of them are unnamed summer fruiting with the odd autumn fruiting (I think) cane, or these could be summer fruiting stragglers.

One cage had 3 rows of rather nondescript plants, some in the shade of a copper beech.  The grand plan was to dig out one row and replace with Joan J.  It's a bit of a risk as I fear the existing ones have a virus.  So Saturday P helped me dig out one row, de-stone and weed, then I had several saved  supposedly autumn canes (I had tied orange binder twine  around  these in anticipation).  So we revised the grand plan and dug out the middle row too.  Today we dug a trench at the middle row site, filled with not quite rotted horse manure, topped with homemade compost and backfilled, then planted the best canes back. Tomorrow we'll dig the other trench in prep for 5 x Joan J ordered from Marshalls with free p&p and 10% discount.  I do realise all this should be done later in the autumn  but couldn't resist free p&p and 10% off :

                   

Do I trim down both summer and autumn canes to 1ft high?
