Gday. Areas? Do roses like full or partial sun, or shaded areas?
I like to plant roses in my house.
You will need a full sun location- 6 to 8 hours of sunlight.

I plan on planting the rose in a raised bed. Will that work?
Rose bushes should be planted when the soil is cool and moist. In regions within USDA hardiness zone 8, January is the best time to plant bare-root rose plants.

I purchased Mancozeb fungicide to stop the black spots on my rose leaves. It came in a pint bottle and the instructions just say to spray it on. There were no instructions that says just spray it on or dilute it. So I put it in a spray bottle and it wouldn't spray. Then I bought another spray bottle and it is still too thick to spray on. How am I supposed to put it on if it is too thick??? Am I supposed to dilute it or what/how to apply.
I can't speak to the products that you have or any application instructions; you will need to contact the manufacturer for any questions.
However these links are what we suggest for treatment of Black Spot disease.

I have oleanders that are 10 ft. tall and wanted to plant rose bushes around the base of the tall hedge of oleanders. Will the oleanders poison and kill anything that is grown in the same flower bed?
There are three issues that raise concern. One is that oleander toxins that are found in its leaves and stems may poison rose roots if they are crushed or allowed to remain on the ground. Will the roses receive 6+ hours of direct sunlight daily while under the oleander? And finally, oleander has an extensive and superficial root system that will compete with your roses for moisture and nutrients. In that competition, I pick oleander to win over the rose. Of course, you could grow roses in containers and avoid two of these potential problems. I have seen short, squat ceramic containers that appear to have enough room for the roots of a small rose.
