Rasberry canes are not normally grown against a wall, they should be cut
down hard now and they will grow new canes from the roots during this year
and these will fruit next year (2009) after which they too are cut down
almost to the ground leaving next years new canes to fruit the following
year...and so on.

Disappointing to have to wait till 2009. Could he not cut down half the
canes and have a few raspberries this year?

Worth saying that one blackberry plant is adequate, but to get a
reasonable crop of raspberries you need several plants.

Strawberry plants do not come true from seed so most gardeners don't grow
that way, they buy in plants propagated from runners etc. That way you get
named varieties with known qualities.

Unless they were one of the alpine types which are usually grown from
seed
