Roses need between six and eight hours of sunlight each day. When choosing a location for your roses, pick somewhere that receives lots of direct sunlight.  In very warm climates, pick a location that gets indirect sunlight when the sun is at its hottest, between 10 a.m. and 4 p.m. This could include near a tree that provides some shade during the hottest time of day. In cooler climates, plant the roses in front of a south-facing or west-facing wall or fence to give the roses some extra protection and reflected heat. Roses need to be watered deeply, especially during their first year and during the warmer summer months. Provide deep soakings twice a week in summer to keep the soil consistently moist. The best way to water roses is with a drip irrigation system or soaker hose that concentrates water at the base and roots of the plant. If the flowers or foliage get wet, it could cause disease, fungus, and rot problems. Along with plenty of water and sunlight, roses also require regular feeding, especially before and during blooming periods. In the spring and summer, between the months of April and July, provide the roses with a monthly application of nutrients, such as:  Granular 5-10-5 or 5-10-10 fertilizer  Fish emulsions Seaweed extract Aged manure or compost Alfalfa meal Roses will thrive when they are pruned regularly, as pruning removes diseased stems, flowers, and leaves, and increases circulation throughout the plant. In the spring, use shears or loppers to remove dead flowers, diseased stems, and old leaves. Throughout the spring and summer, continue removing dead flowers and leaves as necessary.
