Experts and BHG readers answer.
Thanks for writing. To start, make sure your rose garden is in full sun and has moist, well-drained soil that's rich in organic matter. Adding lots of compost to the soil before planting can help a lot, as can covering the soil with an inch or so of compost every spring.
Other than that, the most important thing is to choose rose varieties that are suited to your area. If you want the lowest-care roses around, I'd look at disease resistant shrub roses, such as the varieties featured in this slideshow: http://www.bhg.com/easyroses
