Moving allotment

As long as you add some general fertiliser, such as Growmore or Blood Fish & Bone it should be ok.

You can add container compost but I don't think they're keen on ericaceous compost.

If you are mixing some in with soil then any compost should be ok, I think, but ericaceous is usually recommended only for Blueberries. Also

Thompson and Morgan say

Raspberries can successfully be grown in containers on the patio as long as the container is of a reasonable size about 60cm (24in) diameter. Fill your container with a soil based compost such as John Innes No. 3 as this will add stability to your container and won't dry out as quickly as multi-purpose compost . Plant 6 raspberry canes around the edge of the container and gently firm them in and water them. As with all patio plants make sure the compost doesn't dry out and feed your raspberries regularly with a high potash fertiliser throughout the growing season to encourage lots of delicious fruit.
