Looks live to me. My best guess for its loosing its leaves & not yet growing new ones is transplant shock. I'd be watering it more than twice a week unless rainfall was doing the job for me, watering every other day, giving the equivalent of a large watering can each time. The grass closely surrounding it may be drinking up the water, especially if the ground is not level where it's planted. Would give temporary shade from the heat of the sun in the meantime, good for any transplant in Summer.

Other remedies to try after adequate water for a week. like spraying the bare canes with Neptune's Harvest early in the evening when they're most likely to absorb it.

Ben's right - easier to start fresh than take the time to help a distressed rose recuperate. I'm a softhearted gardener, so give plants "nursing" care when needed. Very satisfying to see them rebound...

Welcome to the forum & the ongoing adventure of gardening! Sue

Thank you for the comments. I'm just going to leave it alone until next spring and see if I get anything. I am just worried that it will not make it through winter even though ours is very mild (daily mean of 4C or 30F). If it does not bounce back I will just replace it next spring. Thank you both :)

I have done something similar an an experiment--cutting back two roses way back after they had just bloomed. They just sulked the rest of the year and didn't do anything. But, they weren't dead. They did start growing the next spring, and I eventually re-grew them into full size plants. I think roses need some rest after blooming.

I can only think of a few things to add. Make sure the rose is well watered before the move. After I move roses I always provide shade until they recover from the move. If it's hot already after a week I slowly remove the shade material. Starting with letting the rose get morning sun. If she starts to wilt I recover it until the rose is ready.

Are those holes that I see in the wood where the rose was pruned. If yes you have bores. This could seriously affect the roses ability to grow back. In order to avoid the ones that drilling into pruned wood seal the cut with something like Elmers original glue.

Discoloration and moldy appearance not promising, I would discard it. Also don't do any future plantings in amended back-fill, if that is what you did. Use instead the same soil that came out of the hole, with mulch applied to the surface afterward.

Thanks for everyone's input. The hole on the cane is not damage from bore, it chipped when I pruned the die off from the top. I did use amended backfill with some compost, may I ask why not? Thanks again. It's too late in the season to plant new roses so I am just going to wait until next spring and see if it will survive the winter. Also, I forgot to mention that the rose is grafted onto Dr. Huey rootstock.

Remove grass until you have a 3 or 4 foot wide circle, and apply two inches of mulch. You may need to add another bag of mulch in October, to keep the rose from drying out over the winter.

With the loss of roots and the heat, the rose may simply be busy making new roots. As long as those canes stay green it has a chance. Where there's life there's hope!
