It would carefully dig it up now, retaining as much of the root mass and surrounding soil as possible. Then repot it now in a generously sized, broad based attractive pot with good drainage holes, using quality potting soil. After potting up, water it once only now. Now cold store it with your other potted roses for the winter. Once a month or so over winter, check the roses for drying out, and water accordingly.

Alternatively, you could also repot it now in an appropriately sized (probably 7-10 gallon), black nursery pot now. Then come spring, find an attractive pot just big enough to accommodate the rose still kept in its black plastic nursery pot, pot in pot, so to say. Just make sure the decorative pot has drainage holes.

I would grow it pot cultured from now on.

Graft unions are a rose bush's weakest point, especially on a tree rose in a colder climate.

Thanks Moses!

I think that’s what I’ll do this weekend. The poor thing gets battered in the wind too. We had a nasty storm a few months back that twisted a brand new nasal cane and split it up the side. I ended up using a ton of string and sticks to secure the cane and it appears to slowly be healing. I think I’ll move it to this beautiful big green pot I have, keep it in the garage and take your advice. Then come spring I’ll move it to a more protected area with less wind and cold. Thank you so much for your help!

Kali,

You are very welcome.

I have a special fondness for tree roses. They are elegant, and lend an air of refinement to any garden. A visitor to you garden will be drawn to the tree roses immediately.

Another thing about tree roses....the fragrant ones put the roses up at nose level. You don't have to bend over to smell them! Older folks like me appreciate that asset.

Pot grown tree roses make them versatile. Move them to wherever you want them. Also, reorienting the pot with once a week half turns keeps the growth from growing lopsided.

I would support the trunk with a slender, but stiff, stout pole, pushed all the way down to the pot's bottom, and tied to it every 6 inches. You could even tie the trunk to the pole with complementary colored ribbon or raffia, making the ties more anesthetically appealing...kind of Alice in Wonderland looking.

If the top of the pole is long enough and extends about 8 inches above be the graft (it will be hidden when the rose leafs out), canes can be tied to it to keep them from snapping off in the wind. This would help take any strain off the graft union, too.

Enjoy your tree rose.
