What are the care tips for making roses bloom more?
"One branch has just faded, another blooms in beauty; spring's work is never idle." Roses bloom in all four seasons, vying in splendor without pause, with emerald branches and red buds, especially endearing. Roses love fertilizer and water, and plenty of sunlight. To make roses bloom more, you must understand their habits and put effort into their management.
Roses have large and numerous flowers and need a lot of fertilizer, so it is best to apply plenty of fertilizer, and sufficient organic fertilizer should be applied before budding. For potted roses, they should be repotted once in early spring. The potting soil formula is: loam 5, leaf mold 2, decomposed manure 2, sandy soil 1, plus a small amount of rapeseed cake, mixed evenly. After that, apply a topdressing every 10-15 days. For topdressing, liquid fertilizer made by composting cake fertilizer with phosphate fertilizer and diluted with water can be used. Especially after the peak bloom in May, fertilizer should be applied promptly to promote summer and autumn blooming.
During the growing season, roses should receive full sunlight, with 8 hours of light per day being ideal. If kept indoors for viewing, they should be brought in before 11 a.m. and taken out before 4 p.m., so they receive the soft light around midday, which helps prolong the flowering period.
Roses enter a semi-dormant state above 33°C, and growth is most favored at an average temperature of 20°C-25°C. Therefore, in summer, appropriate shading and frequent misting should be carried out. To cool down and replenish moisture: during the growing season, it is best to spray water once in the morning and once in the afternoon to create a humid environment and promote the growth of flowers and leaves.
After roses bloom, they should be cut below the third compound leaf beneath the flower to encourage strong new branches and early bud formation and blooming. The key points of pruning technique are: prune weak and short branches first and high, and prune robust branches afterward and short, so as to promote the weak and suppress the strong, encouraging neat blooming. The pruning length of long branches should not exceed 1/2, to avoid delayed axillary bud sprouting. In addition, too many flowers should not be retained per flush; for potted roses, 3-5 flowers are appropriate, while for garden-planted roses it depends on the plant's strength. Retaining too many flowers disperses nutrients too much, making the flowers small and affecting the next flush. Therefore, after budding, strong buds should be selected and retained, cut off 2.5 cm above them, and weak lower buds removed. After buds appear, the large terminal bud should be selected, and flower buds in the leaf axils removed.
