Roses grow well in fertile soil that drains easily. They should be planted in areas that receive full sunlight, as they need at least 6 full hours of sunlight every day. Rose bushes must receive at least 1 inch of water every week during the growing season.
Because rose bushes can easily get fungal diseases such as black spot or powdery mildew, it's important to avoid getting the foliage wet when watering. Avoid sprinklers, opting instead for a soaker hose. Water the plant from below, at the soil line.
In early spring, apply a fertilizer formulated for roses, following the directions on the package. Mulching the plants with organic mulch keeps the soil from drying out and overheating during the summer, and it also helps to keep the soil healthy. The mulch should be between 1 and 3 inches deep.
Some rose bushes bloom once per year during the summer. Those should be pruned immediately after the bush blooms. Rose bushes that bloom at the beginning of spring should be pruned 1/4 inch above the bud eyes, immediately following the appearance of leaf buds. Keep an eye on the plant, and remove any dead or dying sticks, twigs or branches.
