The message
from K contains these words:

The suggestion is that you train last year's growth into a fan shape,
and tie in all this year's shoots vertically.

Vertically? Vertically! Any bramble worth the name will be scraping the
sky if grown vertically!

Even in the first year up to fruit picking time? I grow the various
hybrids, and would expect about 8 ft.

Train them horizontally, and if you want new plants, bend the tips to
touch ground, where they will root.

If not, don't let the canes touch the ground.

then the autumn pruning is
simple - cut all the fan shoots at the base, untie the vertical bundle
and spread them out into a fan.

Remove wood which has fruited.

Isn't that what I said? Cut out at the base all the ones which have been
trained into the fan, which are the ones which are in their second year
and have borne fruit.

If you let last year's and this year's shoots mix in with each other,
untangling them all for pruning in the autumn is a real pain, especially
when you get to the stage of each shoot being 10 ft or so.

No problems, providing you only take short lengths - easier to feed into
the incinerator or on the bonfire thus.

It's a problem! I've done it. Taking short lengths doesn't help because
you keep having to push your hand through the tangle to get at the next
short length. Much easier to keep first and second year growth separate.
