When do roses bloom? Roses are very popular among the public, and many people have the habit of enjoying flowers every year. However, roses do not bloom all year round. They also have specific times. So, when do roses bloom best and when do they open? Let's specifically introduce the blooming time of roses.
When do roses bloom?
Roses, also known as "monthly reds", naturally bloom from May to November, with continuous blooming. However, the control of rose blooming period is still very important, especially for potted roses and cut roses, the blooming period must be controlled to successfully complete the temporary flower arrangement tasks and fresh cut flower supply tasks during the Olympic Games.
In practice, specific situations require specific analysis. For ground-planted roses, based on their geographical location, they should be allowed to bloom more and better from August 8th to 24th while ensuring continuous blooming. The following methods are for reference: Around June 20th, prune all the withered flowers and some blooming branches of ground-planted roses by 50%, cutting to the round bud position in the middle mature part of the flower branches, with a viewing period of about August 1st to 15th; around June 30th, prune all withered flowers and all bloomed branches with the above method, with a viewing period of about August 10th to 25th; after June 30th, prune withered flowers at any time to let them bloom naturally. For potted roses and cut roses, calculate the date of using flowers and prune all branches comprehensively about 45 days before using them.
Fertilization and water management should be combined with the growth of the plant during the above pruning. After pruning the plant, if the new buds do not sprout, spray 0.2% urea on the leaves every 5 or 6 days to promote the sprouting of new buds; if the plant grows fast and the new branches grow beyond the planned range, controlling water supply can slow down the growth. During the water control process, spray water in time after the leaves wilt, and recover within 1 hour as the critical point. Water is the carrier of various enzymes in plants. Insufficient water supply reduces enzyme activity, slows down metabolism, and thus plant growth slows down. If the new branches bloom later than planned, using 0.2% potassium dihydrogen phosphate to spray on the leaves every 5 or 6 days can make the flower buds grow rapidly. The blooming period of roses consumes a lot of water and nutrients in the plant, so the water supply should be sufficient.
How to make roses bloom more
1. Roses need a lot of fertilizer as they have many large flowers. Organic fertilizer should be applied sufficiently before germination. For potted roses, they should be repotted once in early spring with the following soil formula: (loam) 5: (decayed leaf soil) 2: (decayed manure) 2: (sand) 1, plus a small amount of rapeseed cake, mixed evenly. Then, top-dress every 10 to 15 days. The top-dressing can use liquid fertilizer made of cake fertilizer and phosphorus fertilizer diluted with water, especially after the full bloom in May, fertilization should be applied in time to promote summer and autumn blooming.
2. Roses should fully receive sunlight during the growing season, preferably maintaining 8 hours of sunlight per day. If used as indoor decoration, they should be moved in before 11 am and out before 4 pm, so they can receive the soft light before and after noon, which is beneficial for extending the blooming time.
3. Roses are in a semi-dormant state above 33℃, and it is most conducive to growth when the average temperature is between 20 to 25℃。 Therefore, proper shading and multiple water sprays should be carried out in summer to cool and increase humidity. It is best to spray water in the morning and afternoon during the growing season to create a humid environment to promote the growth of flowers and leaves.
4. After roses bloom, the branches below the third compound leaves should be cut to promote strong new branches and early blooming. The key points of pruning technique are: cut weak and short branches first and higher; cut strong branches later and shorter to promote weak branches and inhibit strong ones, making the blooming uniform. The pruning length of long branches should not exceed 1/2 to avoid delayed sprouting of axillary buds. In addition, the number of flowers per batch should not be too many. For potted roses, 3 to 5 flowers are suitable, and for ground-planted roses, it depends on the strength of the plant. Too many flowers will scatter nutrients and affect the next batch of flowers.
