Cane fruit on clay or on container?

[Heidi Tradescant]

I live in London and would love to start growing cane fruit.

My patio has a small stretch of clay soil, other than that I have to resort to containers.
What about
a) blackberries
b) loganberries
c) tayberries
d) Japanese wineberries ?

All seem to rather want "free draining rich soil" and are not considered really suitable for containers. Yet an offshoot of a local bramble seems to be happy enough. Should I risk the clay or rather opt for containers? How big would they have to be in the first two years? - Are there any other soft fruits you cold recommend for heavy soil?

Thank you in advance.

Blackberries, loganberries and tayberries can get very big - I wouldn't have thought a container was a great idea.

Clay soil is very nutritious for plants, and can be improved drainage wise by adding organic matter. Home-made compost, lawn clippings etc.

Do you have a fence you can train these fruit on?

Thank you, Rusty Lady,
Yes, I do have a fence. I live on an estate and we are all fenced in, big strong sturdy, black metal bars (prison springs to mind). That's why the idea of cane fruit came up in the first place. I had dug all organic material in in autumn I had, but my Oregon blackberry has given up by now. I took some rooted shoots off a local bramble and they are doing fine. I suppose try and learn it is...
Thanks again.

Raspberries are quite shallow rooted and seem to grow anywhere. A friend grew raspberries in a pot for several years - I know because she gave them to me afterwards!
