Hi all. Earlier this year thecatsfather's dad died, and at the funeral several of us were given "Peace" roses (hybrid tea) in his memory. As we knew we were moving soon I put it into a reasonably big pot (about the size of a bucket), and it came with us when we moved last month.
It's grown lots and is now in glorious bloom (4 huge flowers, another 5 buds growing daily). It's getting quite big too (about 3 ft tall from the top of the pot). I don't want it to suffer from being in a pot too small, but equally I don't want to plant it out and risk it. So advice please, I'm presuming it's best to wait until it's finished flowering then plant out, but should I wait until the middle of winter then prune right back and transplant then? Or do it sooner so it can get some more time to grow without being constrained by the pot. On reading up I see it's potentially going to get quite big (my only rose previously has been a "Happy Anniversary" which is a smaller floribunda which has bloomed each year for the past 10 years in a similarly sized pot. Hadn't really considered that the Peace would get so big so quick
