Can you tell me what this is on the rose stem?

Dipoloepis rosae is the gall wasp that causes this. the robin's pincushion is the plants wound response to the larvae of the wasp. they are just an interesting side effect of the world of nature.
there is nothing missing in the plant's nutritional, horticultural needs however.

Ooh, interesting, haven't seen one of these for a while... it will pass, no need to do anything unless you hate the look of it and you want to cut it out.

I hope you will leave it! These used to be a common sight on wild roses but haven't seen any for years.

Robin's Pin Cushion (Rose Bedeguar Gall). It's caused by gall wasps. It won't hurt the overall plant so there's no need to do anything but let the little bugs have a life cycle.
It may be an indication that the plant needs a bit more water & feed though
