Rose leaves with dark patches on them have a fungal disease called Black Spot. This disease is caused by warm temperatures and humidity. It will eventually defoliate the plant and weaken it severely. You either have to spray the roses with a fungicide to keep the leaves healthy, or you have to plant roses that are highly resistant to blackspot. Fungicides are somewhat toxic and need to be applied regularly during the growing season. It is important to understand that they are a preventative, not a cure--you have to spray the roses BEFORE they get the disease--spraying will not cure the leaves already infected.





For a good list of roses that are highly disease resistant, look at the 'Earth Kind' list of roses developed by the state of Texas. These roses were tested over a long period of time to choose varieties that look good and bloom well with little use of chemicals.





As to the brown flowers, you may have another rose disease called Botrytis. This is a disease also prevented by fungicides, so if you spray for Black Spot disease, that should take care of the brown petals as well. Another cause of brown petals are a pest called Thrips, which are a very tiny insect that likes to rasp the edges of rose petals. They require frequent applications of pesticide to prevent. You can tell if you have thrips or not by shaking a flower over a piece of white paper. If tiny bugs will fall out of the flower and show up on the white paper--those are thrips.





Another way to go is, as before, plant types that are not so affected by Thrips. Thrips tend to prefer white and other very pale colored roses.Why does my roses bloom with dead pedals?
Home dept. Call the garden shop, and talk to the rose person, they can tell you what you need and how to do it. If yo bye plants there, if they die, or do what yours is doing they will replace them up to one year.
The black spots on your leaves is called Black Spot disease and you can get a liquid for this and you can get it at Wal-Mart and other nursery's. Your leaves are also turning brown and yellow,just spray them and make them all well.

It will only be a time that the roses will be attacked also. It sounds like you might have aphids eating at them. or a it might be blight. or fungus that attacks the leaves.
