Im in zone 7b in Maryland. I have Cinderella fairytale in a large pot. I have had it for 3 years. I got it from Palantine roses so it is grafted. It is about 4 feet tall (above the pot). I haven't planted it in the ground yet due to voles.
I have sprayed it with neem oil (I have been inconsistent with this), but I think I will stop spraying it with neem oil. The neem oil gets rid of the aphids in the spring, but in the summer this rose gets thrips. The thrips really affected a large flush of blooms this summer. I read that spraying for aphids in the spring means that beneficial insects who eat aphids will not come to the plant and those same insects eat the thrips later in the summer, or something along those lines. I am also going to plant more native perennials in order to attract said beneficial bugs.
This rose bush is very healthy. It has formed a very attractive shape. It's sturdy and holds the flowers upright. Also, the flowers last a long time. The flowers are beautiful. It has a large flush in spring and several smaller flushes afterwards. It looks very nice both close up and far away. Right now half of the bush is getting more shade, and that side blooms about half as much as the side in the sun. Consequently, I am going to move it completely into the sun. It has periods of times between flushes with no flowers on the bush.
I fertilize it with a diluted liquid fertilizer- either neptune's harvest, fox farm, or compost tea - at least 2 times a week. I water it every day during summer because it is in a pot. After a rainy period some of the leaves look yellowish, but I think this is because the rain washes the nutrients out of the pot. I never let water get on the leaves when watering it.
This rose has never had an outbreak of blackspot or any other disease. The main problem I have is with the sawfly larvae. I pick them off by hand every so often and that seems to keep it under control.
The fragrance of this rose is like a green apple. It's not a strong fragrance and not a distinguishing feature of this rose.
I think this rose would definitely prefer to be in the ground because it keeps sending roots out of the pot into the ground. I've read about planting a rose in a large growers pot with several holes in the bottom, and keeping the top of the pot a few inches above ground in order to keep the voles out. I think I may try that next spring.
6/24/2021- This rose continues to not succumb to blackspot or any other disease. However, I still have not been able to put it into the ground, and I think it is suffering in the pot because it is not very vigorous at all and is very slow to repeat this year.
