I have a rose called guinee. only small white flowers this year.?

Question

this rose had a beautiful deep red rose the first year, nothing last year and these flowers which look like hedgerow roses this year. what's wrong?

Answer 1

It's reverted.

Cultivated roses are usually grafted onto a briar root stock.  You have to be careful not to let it grow from the base or the briar will take over.

Have a good look at it and see if there's anything left of the cultivated rose - it will have bigger leaves.  If there is, cut off everything else right back to the main stem - or if it's growing out of the ground, back to the main root.  If there isn't, dig it up and use it for hedging.
