Couple of questions - how long have the roses been in the same pots, and precisely how big are the pots, depth and width?

I'm not a fan of roses in pots. As the stems are still green and no signs of buds, I would take them out of the pots and try them in the open ground. At the end of the day, you've nothing to lose.

I'm not a fan of pots period, except for target practice.

The roots may have been attacked by vine weevil grubs. Check the soil for grubs which look like this: http://www.downgardenservices.org.uk/vineweevil.htm

If you find any, immediately treat the soil (and the soil in all other pots). Various products are available:

I'm with Jimmytheone on this - I reckon its the pots that are the problem - other than patio ones, roses generally don't do well in pots, so its probably a much larger, or actually, much deeper pot that's required, or in the ground with them. But without seeing the pots or knowing the measurements, its impossible to say 100%...

the pots were terracotta 14 "x 12"

thank you i have put them in garden to try there were no bugs in the roots

thank s to all

Hopefully they'll do better now - keep well watered during dry spells this year though, Bigalfie...
