Whether it's in a garden or on a balcony, everyone wants their roses to bloom beautifully and large. The question of how to cultivate roses for large blooms is quite comprehensive. This article has compiled some key points to consider for large blooms, which should be helpful for rose enthusiasts.
1. Roses require a lot of fertilizer for large and numerous blooms. It is advisable to apply sufficient organic fertilizer before germination. For potted roses, they should be repotted once in early spring with the following soil formula: (loamy soil) 5:(decayed leaf soil) 2:(decomposed manure) 2:(sandy soil) 1, mixed with a small amount of vegetable cake. Then, apply a top dressing every 10-15 days. The top dressing can be a liquid fertilizer made from cake fertilizer mixed with phosphorus fertilizer, especially after the full bloom in May, to promote summer and autumn blooming.
2. During the growing season, roses should be exposed to plenty of sunlight, ideally maintaining 8 hours of light per day. If used for indoor display, they should be moved in before 11 am and out before 4 pm, allowing them to receive the soft light before and after noon, which is beneficial for prolonging the blooming period.
3. Roses enter a semi-dormant state at temperatures above 33°C and grow best at an average temperature of 20°C-25°C. Therefore, proper shading and multiple waterings should be done in summer to cool and humidify. It's best to spray water twice a day during the growing season to create a moist environment, promoting growth of flowers and leaves.
4. After roses bloom, the third compound leaf below the flower should be cut to promote sturdy new branches and early bud formation. The key points for pruning are: cut weak short branches first and higher; cut strong branches later and shorter, to promote the weak and suppress the strong, ensuring uniform blooming.
The pruning length of long branches should not exceed 1/2 to avoid delayed sprouting of axillary buds. Also, it's not advisable to keep too many flowers; for potted roses, 3-5 flowers are recommended, and for ground-planted roses, it depends on the plant's strength.
Too many flowers can lead to scattered nutrients, resulting in small flowers and affecting the next batch. Therefore, after germination, select strong buds and cut off the top 2.5 cm, removing the weak buds below. After the buds appear, select the large terminal buds and remove the lateral flower buds.
