When Do Rose Flowers Bloom
Why do we call the rose "yueji" (monthly season flower)? There is actually a reason for this: because the rose blooms in all four seasons, it is called the monthly season flower. Moreover, when the rose blooms, the flowering period lasts a very long time, one wave after another, so the rose never stops blooming throughout the year. So as for when the rose blooms? I think everyone should understand by now.
The length of the rose's blooming period depends on the season and climate. Generally speaking, the first flush of flowers in spring lasts relatively long, and the last flush before winter begins lasts the longest. It mainly depends on temperature: the higher the temperature, the shorter the blooming period; the lower the temperature, the longer the blooming period. This is the general rule. Flowers with hard petals and thick petals have longer blooming periods; flowers with soft petals and thin petals have shorter blooming periods. Put it this way: with suitable season and climate, it is not surprising for a long-lasting bloom to stay open 10 days or 8 days; with unsuitable season and climate, it will last at most 1-2 days. Of course, people have subjective initiative: even in the most unsuitable season, you can artificially add a reed curtain or shade net, or move it under the eaves or tree shade, and this can also extend the blooming period.
How Can Roses Bloom More
1. Rose flowers are large and numerous, so they need a lot of fertilizer; therefore, more fertilizer should be applied, and sufficient organic fertilizer should be applied before budding. For potted roses, the pot should be changed once in early spring. The potting soil formula is: (loam) 5 : (leaf mold) 2 : (decomposed manure) 2 : (sandy soil) 1, then add a small amount of rapeseed cake and mix it evenly. After that, apply fertilizer every 10-15 days. For topdressing, liquid fertilizer made by fermenting cake fertilizer plus phosphate fertilizer can be diluted with water and poured on. Especially after the peak bloom in May, fertilizer should be applied in time to promote summer and autumn blooming.
2. During the growing season, roses should receive full sunlight, and it is best to maintain 8 hours of light per day. If they are kept indoors for viewing, they should be moved in before 11 a.m. and moved out before 4 p.m., so that they receive the soft light around midday, which helps prolong the blooming time.
3. Roses enter a semi-dormant state above 33°C, and growth is most favorable when the average temperature is 20-25°C. Therefore, in summer, appropriate shading and frequent water spraying 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.
4. After roses bloom, they should be cut below the third compound leaf beneath the flower to promote the growth of sturdy new branches and the early appearance of buds and flowers. The key points of pruning technique are: weak short branches are cut first and cut high; vigorous branches are cut later and cut short, so as to promote the weak and restrain the strong, and encourage uniform blooming. The pruning length of long branches should not exceed 1/2, to avoid delayed sprouting of axillary buds. In addition, too many flowers should not be kept per flush; for potted roses, 3-5 flowers are appropriate, while for ground-planted roses it depends on the strength of the plant. Keeping too many flowers disperses nutrients too much, making the flowers small and affecting the next flush of flowers.
That is all for today's introduction on the question of when rose flowers bloom. I hope the above content can help everyone!
