Hey Friends! Recently my rose's leaves have been curling up like if they were drying up, I have been watering every day like always, but I think it might have been a reaction to the recently applied fertilizer, but I followed the instructions and everything! Please help, I don't want my roses to get sick! :,(

(Yes, I know is not very visible in the pictures)

Spider mites?

I agree with porkpal; in the second photo, I see webbing ... my guess is spider mites.

I absolutely agree, mites!!!
As these insects suck the juices right out of the leaves, cell walls collapse and the leaves curl. That is the simplest way to explain.
Bayer's 3in 1 insect spray from garden center, Lowe's or Home Depot.
Put applicator on "mist" and spray plant thoroughly, top and bottom of leaves etc. in a week to day days, spray a second time and then in a week to ten days spray a third and final time.

@A_dinosaur ....

Spider mites prefer a HOT, dry climate to flourish. For me, they are easily controlled by washing the plants throughly with water ... especially the undersides of the leaves .... with just water for three days in a row. This breaks the breeding cycle. After that, you only need to wash your plants down once a week.

I have followed this practice for years and grow over 100 roses and have always been successful in controlling spider mites in my garden;

I have one rose that I call the canary-in-the-mine. It always gets spider mites first. As soon as I see it start to get spider mite damage, I go into action and wash down all of the roses to break the breeding cycle. I have never used any chemicals to control a mite infestation.

Of course, there are a lot of right ways to grow roses ...
