I would wait until the temperatures are higher Arwadoo.....The frost may not hurt the parent plant but I think it would make short work of any graft. Also, the bushes aren't actively growing much when the temperatures are low. You want the growth of the plant to be active so that the graft will be successfully "absorbed" into the parent.

Hello Gilli
Thank u for the response.
Under the circumstancesprevaling will the scion wood be cut and utilised as and when the temperature improves or will the scion wood have to be severed and stored now. The buds in the would be scions are already swoolen and looks like breaking open.

I have always understood that the grafting process should take place very quickly with the cut scion being immediately placed onto the stock plant. The cut pieces will dry out very quickly - sometimes within seconds. The best time to graft is when the blooms are fading and petals dropping on the scion plant, but before the buds swell in preparation for the next flowering. I think storing the scion would be risky.

The condition prescribed will be followed Thanku
I have uploaded a photo of a foolish rose who has braved the snow and is in bloom withsnow allround.

Good luck with it Arwadoo.....Be sure to post a pic of your grafted rose. :o)
