I think it depends on your soil and their location. Did you plant them in individual pots, or are they together? If they are together then you should separate them before they have a chance to get bigger and make the job harder.

I've planted baby roses with similar sized roots straight out into the ground and they survived, but it does help to give them a bit of a boost in pots first. How big are they this spring? They shouldn't need a bigger pot, 3 gallons is plenty, but I reckon you can see how they look when they have well and truly broken dormancy and then decide whether to plant them out or let them grow a little longer. Some roses do better when planted out and others don't seem to mind being kept in pots.

Hope you are staying warm!

They are already separate, and I don’t have the bed prepared yet! I’ve never grown a climbing rose before so I’m worried they’d grow too big this year for their pots. I guess I don’t know what to expect. Thank you!

They are almost the same size as the photo, they didn’t do much yet, but still dormant

My experience with QS is that it roots tremendously easy and just takes off.

I had one in too much shade and when I went to move it it fell apart into three pieces. All survived.

The trellis one was on fell over in one of our windstorms and damaged a cane so I cut it up, dipped it in rooting hormone and stuck them in a pot-they all survived.

It‘s becoming the Peggy Martin of my yard :)

You can relax, there are some enormous roses crammed into one gallon pots around the stores every year and you get them home and plant them out and they do just fine. You've probably got a year before they get desperate.

Keep us posted how they do for you!! And welcome to the Rose forum :)
