This is my second times I post here, I think. Actually I do not grow roses. I grow chilies. I have a couple of rose plants the other two are very small red. They are not in the containers and without any protection they survive the winter snow many years. Since last year I started take care of my roses, such as trim and fertilize :-).
The temperature here is now 1 C to 4 C, all my other plants are dying but this rose is blooming. I am very surprised to see her potential to deal this harsh climate. She has only two flowers.
It is the same plant. The leaves are a bit yellowish, I do not know the exact problems it may cause by the climate or nutrient deficiency. I have not fertilized about 2 months now. To see these yellowish leaves I am thinking to fertilize the plant. So I am requesting some advice here.
