Select disease-resistant varieties of roses. This will prevent the spread of disease between plant material that touches the plants next to it.
Cover the soil in the planting site with 2 to 4 inches of organic compost. Cover that with a layer of superphosphate at a rate of 3 lbs. for every 100 square feet of soil. Turn these into the soil at a depth of 12 inches with a shovel.
Dig holes in the planting site for the roses. Make each hole as deep as the rose's container, and twice the width. Space the holes 18 inches apart for shrub or hybrids, and 8 feet apart for climbing vines. If you are planting in rows, space the rows 36 inches apart.
Remove each plant from its container and lower it into a planting hole. Fill the hole with soil and water until the soil settles. Continue watering at a rate of 1 inch per week.
