You can plant raspberries now but I'm not sure what you mean by 'in tubes' if it is the sort of thing used to protect young trees from rabbits and deer not really. What you can do is create a fruit cage and grow your raspberries in that.

I planted my successful raspberries when someone offered me some of their canes, when they looked like dead twigs with roots attached! It was late Autumn if I remember correctly. I'm fortunate not having to protect mine in tubes (I assume to mean tree tubes?), but I don't think they would make any difference to when you need to plant them. I would say plant them when the nursery suggests to, or like I did, taking and planting them when they don't have any leaves or fruit on.
I'm intrigued as to why you want to plant them in tubes? Do you have trouble with creatures nibbling young plants of yours?

Think they maybe mean TUBS?

Ah good point Donnaj, you can plant raspberry canes in tubs but they need to be pretty large ones! Much better off in the ground if possible.

Kazz late autumn and early spring are the times to plant raspberry canes.

I have my raspberry canes in tubs at the minute - as I'm not sure where I'm going to put them long term :)
They're in pots that are a good 2ft diameter at the top - probably about 35L ericaecous comport - got 4 canes per pot .... first year so finger's crossed they'll bear fruit.

They'll be okay for a year or so, not sure about long term. Our last lot of canes walked themselves forward a few inches every year. The ones we have now were only planted last March so can't say if they will do the same.
