Tulamaleen Raspberries with deep roots?

[fishpond]

Tulameen Raspberries planted in winter 2011.
Good enough crops including this year.
Alkaline soil--clay + flint +chalk + plenty of calcium carbonate.
Plants this year were showing severe signs of chlorosis so I made the decision to replant in a new bed with plenty of depth and plenty of manure.
Still with me?
Dug some up today to replant in new bed (yes, I know should be done during the dormant season---if it works it works, if it doesn't --I haven't lost anything)
All roots were going straight down over a foot and in one case over 2 foot so they're out of the manured zone --into chalk subsoil and probably waterlogged--which explains the state they were in.
But why straight down roots.
They have been watered, all be it with a PH of 7.
But , why straight down?????
Any ideas, no matter how silly it may seem?

Really no idea unless they took the easy route through loose topsoil. That's no more than a guess mind.

Had a quick looksee on gurgle and found this caveat on a sales website.

"This plant is protected by the Plant Variety Rights. Illegal propagation without a licence will lead to prosecution."

Now everyman and his dog propagates new canes from their raspberries after all, they propagate naturally. A bit unrealistic

to expect folks not to do so

Suspect it's more about propagating to sell on rather than for personal consumption

I think Alison is right as usual. The UK.gov page says,

"These rights only apply if the plants are being used for commercial purposes - they do not apply to any act done for private and non-commercial purposes, for experimental purposes or for the purpose of breeding another variety."

Am going to print this off and remind OH

I find that raspberries do go down deep and we have topsoil that is over 3ft deep, i have some that go under the veg patch and come up 12ft away yet I put down screening to 3ft depth and it must have got under that, if it goes any deeper the Chinese will be selling copies of it...
