Raspberries not growing

Seasons greetings to all and hopefully some assistance gained.

I live in Cyprus (Mediterranean) and brought some raspberry canes from Crimea 4 years ago. They were planted in large pots with potting compost. They grow to 15 inches high and have buds on them, but the buds never open and the canes do not grow any further. Its like theyre in a suspended state.

For 2 years they were in sunlight (strong in the summer) so for the last year are now in a sheltered place with lots of light but no direct sun light. Still no growth. Can anyone give me pointers please.

Thanks in advance.

Can you post a picture or two Doug?

Im certainly no photographer either but here goes. They just sit with small buds that never come to anything.

See if they are rootbound. They would benefit from a bigger pot

Soil too alkaline? Temperatures too high? (Probably not since you mentioned you took them out of direct sunlight.) Raspberry bush dwarf virus? Also check for these http://www.extension.umn.edu/garden/yard-garden/fruit/integrated-pest-management-for-home-raspberry-growers/cane-diseases/

I have now replanted outside against a stone wall for some protection but some dailly direct sunlight. The roots were pretty tight and wet when I opened the pot so heres hoping.

Thanks

A pretty standard rule for berries:
Blackberries = Full Sun
Raspberries = Afternoon shade
