Juniper out, roses in
First of all, getting those roots out is going to take some work. Old junipers are hard to remove, and if they are really large you might have to resort to a backhoe. Or you might want to hire a local landscape crew to dig up these established roots. Once the roots are gone, add a layer of fresh soil, compost, peat moss, or rotted manure and till it into the existing soil. Roses require good drainage, so you need a loose, friable soil. Because you are a beginning gardener, I suggest that you plant easy-care roses, such as shrub roses. Keep in mind that shrub roses vary in size. Plant them at least 3 feet apart; if you have the space, consider planting groups of three of the same variety and color together. Look for hardy shrub roses that are on their own roots (not grafted). Some popular and easy-to-grow roses that will bloom throughout the summer are 'Carefree Beauty', 'Bonica', and 'Graham Thomas'. Contact a reputable nursery in your area, your cooperative extension office, or the local rose society for ideas on what varieties do well in your area.
