Roses are one of the most widely cultivated species of flowers in the world. Rose bushes produce many flowers in the garden annually. These plants require a lot of care to ensure they grow the best, largest and most fragrant flowers possible. Several standards of care apply to nearly all rosebushes.
Old and modern roses grow best in a well-prepared seed best that drains water evenly. Place the rose bed in an area that gets good air circulation and at least six hours of sunlight, says Texas A&M University. Organic material such as compost or peat is required in most beds. A 1- to 3-inch layer tilled into the soil will suffice.
Protect rose bushes against drought by applying a thin layer of mulch two to three times a year. Mulch reduces weeds as well. Pine bark, pine needles, leaf mulch or other weed-free mulching materials work well. Watering is required every seven to 10 days when mulch is properly applied.
Rosebushes are heavy feeders and require nutrient replenishment regularly. Use a soil test kit to determine the nutritional deficiencies in the soil. Obtain a soil test through garden centers, or send soil samples to your local university extension service. Plant rosebushes in a soil with a pH between 5.5 and 7.0. Add organic materials, as well as a quick-release, water-soluble fertilizer with an NPK ratio of 5-10-5, 10-10-10 or 12-12-12 applied according to the packaging instructions.
Prune to reduce disease and produce healthy flowers. Pruning needs vary between varieties. Remove dead, damaged or diseased branches on the bush as well as thinning to improving air circulation. Prune in the spring, says the University of Illinois Extension. Cut with a sharp instrument at a 45-degree angle 1/4 inch above a bud.
Winterize to protect the rosebush from cold weather. The canes of the rose bush are tied together. A mound of dirt is piled 8 to 10 inches high around the canes, according to Ohio State University. This protects the plant from cold ground, wind and snow which may break the cane.
