Article in English: Purchase a balanced granular or liquid 10-10-10 fertilizer. This sort of fertilizer will incorporate nutrients back into the soil. The fertilizer should be applied once every 4 weeks during the growing season, or the beginning of spring.  You can also create your own nutrient powder by mixing together 1 cup (240 ml) of bone meal or superphosphate, 1 cup (240 ml) of cottonseed meal, 1⁄2 cup (120 ml) of blood meal, 1⁄2 cup (120 ml) of fish meal, and 1⁄2 cup (120 ml) of Epsom salt (magnesium sulphate). Find a rose-specific fertilizer at your local garden center. They provide exactly the minerals and nutrients that your roses need. Use a garden hose to water the soil thoroughly before spreading the fertilizer. Watering it before applying fertilizer prevents the fertilizer from burning your plant. Lay the fertilizer down evenly around the bush up to the perimeter of your growing area. Keep the fertilizer at the base of the plant, but don’t let it touch its main stalks. If the fertilizer is allowed to come into contact with your plant’s leaves, the fertilizer will burn the leaves and cause them to wilt. Most people fertilize their rose bush at the start of spring; however, if you notice new growth in your rose bush, you can start giving it fertilizer even if it's a bit early. Your rose bush will require more nutrition when it is growing and budding. During the peak growing season, fertilize your rose bush every 4-6 weeks.
