P.S. I forgot to add that once it has started to recover you can slowly transition it to a sunnier spot.

Hmm I could totally be wrong but to me it looks like sunburn. Did you harden it off at all, or did it go straight from the shipping box to 5 hours of direct morning sun?

I agree with KS. Definitely follow her recommendation. When you have a few lant that needs to recover and esp. still in the pot, put it in part shade/part morning sun which isn’t too harsh for it. Keep it moderately watered.

Roses grow well in spring in “mild cool conditions w/light sun for 6 hrs.” That is their favorite way to grow. When they are weakened needing to recover they especially need those light sun/shade conditions. Remember tgey used to live in a green house with perfect easy to live in conditions. They aren’t used to hot harsh outdoor.

Also, if I keep my potted new roses outdoors for awhile before I plant them then I lower the pot part way into the ground to keep them from drying out. Pots easily dry out in hot sunny days more easily than in ground plants.

For your rose it’s important to first see it isnt “overwatered anymore.” And not to dried by the hot sun either.

Have fun! Best wishes on its recovery!

Magpie, I didnt even think about it when I put it out. I guess I burned it. is the black on the base also caused by sunburn?

black on stem can be cause by rotting in water unless it was extreme hot, too. Then maybe sunburn, too. Any extreme weather or care could cause die back-blackish in a rose. No worries. The leaves above that stem may die but the canes that have green at the base will grow new shoots. Just cut off any dead parts of rose, fully dead cane if at base and dead leaves and that encourages new growth. (We in colder climates have die back every winter, prune it off and enjoy watching new growth.) Leaves may wither for awhile as rose decides what part of it is healthiest. Keep the part that grows healthy and it will send out lots of new shoots as it begins to grow. Eventually, when it’s planted in good soil it will grow rapidly with much new growth.

i doubt sitting in water for a few hours one day had much of anything to do with all this.. besides .. if that would have caused a problem it would have been a root problems.. and it wouldnt have showed up in a few days ...

so its probably the sun problem ...

its was stressed from shipping .. the sun stressed it .. its stressed ... get it in full bright shade.. and let it settle down and hopefully it will releaf and get going ...

one other caveat.. thats a pretty small pot to ever have the pot itself in the sun.. it might allow the roots to get to hot.. wait for it.. stressing the plant even more ... and being on a brick patio in the sun you might take into consideration radiant heat from the brick ...

also.. if it was greenhosue grown.. thats a whole other level of light intensity stress ...

good job on the seller sending a new plant.. no matter what happens to this one ... you will have a free plant ...

in my MI .. later freezes are a thing.. and a hard hit rose can and will releaf ... if the plant is well established ... yours is not.. but there are still good odds it can recover and come back... if you put it in full bright shade.. and water it properly .. it is not a water loving houseplant .. so do not keep it sodden ... but dont let it go bone dry ...

When I get a new rose I gradually acclimate it to the sun. I start with an hour or two and gradually add more time over a week.

There is some great advise above.

Best wishes on the recovery
