Blackcurrant Ben Connan growing

I am thinking of buying
Blackcurrant Ben Connan
What depth of soil should i plant it in and if i plant it in December time is that going to harm the plant ?

 

@JWK
Would you agree that if the intended site is exposed to wind, or the plants bare -rooted, that our OP should prune heavily, to two buds, so that the new bushes establish roots before top load?

 

Thanks for the reply , theres definitely not 18 inches of soil in the garden. Can anyone suggest a fruiting plant that will grown in maybe 4 or 5 inches of soil

 

What kind of soil do you have? It is always worthwhile providing details of (approx) location and soil type.
While 18" may be ideal, they will make the best of what there is. Plenty of organic matter/bonemeal will help. Mine do alright without that depth of viable soil, having marine clay /silt over chalk. You could look at blueberry, gooseberry,strawberry also. Blackcurrants will also grow in containers, so long as these are large enough (25litre +) so long as sufficient water is provided, you could also build raised beds.
