From what I can see, you've done a very good job at bringing your monster under control. Yes, it looks like a Hybrid Tea. The first one that comes to mind is Tropicana. An older, very tough HT that is still in commerce today because it is so tough and reliable. The biggest thing you can do for it right now is give it a lot of water. Think about how big the root system must be. A bush that size needs water to function in a proper way. It should start to shut down for the winter soon so don't feed it anything. Just keep it well watered. When spring comes around in your neck of the woods, get a bag of Esponia (SP?) from your local Lowes or Home Depot and sprinkle about a cup around the bush. It should look great when it blooms again in late spring.

Generally, Reno is zone 7a. You did a good job of taking out all of that dead wood. Most roses can tolerate your zone without winter protection. I would continue normal watering and give it a good fertilizer during mid to late April.

I would add compost around the base right now.

Is the rose surrounded by concrete?

@ken Thanks for the advice. Ill keep that in mind. The root system is probably pretty wild.

@DesertGarden Thanks for the clarification. Ive figured it will be fine; it's lived this long without help. Before I started watering it, it probably hadnt been watered for months. Yes the rose is surrounded by concrete, its only in a 1' by 1' diamond patch of dirt. The place where I work is right off an airport runway in a very industrial part of town.

That amazes me that a rose or trees I've seen planted like this can make it surrounded by concrete. You are really helping and more water and Epsoma or Rose Tone in Spring can really help but you don't have much room to put it on the soil there. Good luck!

It looks more like Chicago Peace to me. Tropicana does not have that variation of colours. My tropicana is more orange, definitely darker orange. This has the combination of orange and pink which CP has. I could be wrong as I am certainly not an expert.

I agree Tropicana (I grew 52 years ago as a 12 year old) is not this plant.

I've seen lots of roses, trees and all sorts of plants grow in tiny squares surrounded by concrete like this. I don't know how they manage but they do. I'm sure the root ball extends far and wide in all directions below that concrete. The problem is getting it sufficient water with such a small patch of soil to work with. But then again, it seems to have done just fine on its own, lol! From what I can see on the zone maps Reno is in zone 7a. You shouldn't have to worry about winterizing. As for an ID, I'd wait for the spring flush and take lots of pictures of the plant and the blooms in all stages. Then post here and maybe we can give you a better idea of what it might be.

I would say, don't prune anymore right now. It is not the time of year for this.

I think you have done a great job clearing the dead wood and opening up the old bush. It should look beautiful next Spring.
