The Latest Large-Flowered Rose Planting Techniques and Methods Tutorial
The large-flowered rose is also known as the fragrant rose, the showy-flowered rose, and the ornamental rose. It is a plant of the genus Rosa in the family Rosaceae, with a sturdy and handsome growth habit, large and full blooms, elegant flower posture, beautiful flower form, and a rich fragrance. It is suitable for growing in an environment with ample sunlight and good air circulation, and it is not demanding about soil. Now let us take a look at the planting techniques for large-flowered roses!
Propagating Large-Flowered Roses by Cuttings
Propagation of large-flowered roses by cuttings is generally carried out in early spring or late autumn when the large-flowered rose is dormant, by cutting mature branches with 3 to 4 buds for rooting. If softwood cuttings are used, appropriate shading is needed, and the seedbed should be kept moist. After cutting, roots generally form in 30 days, with a survival rate of 70% to 80%. If rooting powder is used to dip the branches when cutting, the survival rate is even higher.
Managing Large-Flowered Rose Cuttings
1. Building a frame for shade: The optimal temperature for rooting large-flowered roses is 20°C to 25°C. During the cutting period, a frame needs to be built for shade. A plastic shed can regulate the temperature and humidity of the soil and air, while a shade net can prevent direct sunlight and lower the temperature. If the temperature is too high, in addition to covering with a shade net, watering to cool down and ventilation to cool down can also be used.
2. Timely watering: In the early stage of cutting large-flowered roses, the cuttings have not yet sprouted leaves, so water supply should not be too much; generally watering once every 7 to 10 days is sufficient. After one month, the cuttings begin to take root and send out shoots, and water consumption gradually increases, so watering should be done once every 3 to 5 days. The amount of watering should be determined according to soil moisture and air humidity, so as to keep the soil moderately dry and moist.
3. Reasonable fertilizing: Large-flowered rose cuttings do not need much fertilizer. Since base fertilizer was already applied when preparing the land, there is no need to fertilize the soil again before the seedlings are transplanted, but foliar fertilization should be carried out. That is, one month after cutting, apply foliar fertilizer once every half month, alternating between 0.3% urea liquid fertilizer and 0.2% monopotassium phosphate liquid fertilizer, to promote rooting.
Cultivation and Management of Large-Flowered Roses
1. Cultivation site: The large-flowered rose is a light-loving plant. During cultivation, a sunny location should be chosen, avoiding planting beside tall buildings, under tree shade, or on the shady side of hillsides. The ideal soil for cultivating large-flowered roses should have a good granular structure and be rich in organic matter.
2. Planting spacing: The plant and row spacing for cultivating large-flowered roses varies according to the purpose of cultivation. For variety nurseries used for breeding or scientific research, the commonly used plant and row spacing is 150 cm × 80 cm.
3. Reasonable pruning: Before planting large-flowered roses, the seedlings need to be pruned once, cutting off damaged branches, diseased branches, and weak branches. Damaged or overly long roots should also be cut off. After pruning, apply a wound-healing and antiseptic film to the wounds so that they heal quickly.
4. Water and fertilizer management: Large-flowered roses like fertilizer, especially organic fertilizers such as barnyard manure and compost. The flowering period is long, so during their growth, attention should be paid to applying chemical fertilizers for quick effect. In addition to maintaining sufficient water and fertilizer, spraying flower-strengthening agent during the bud stage can promote strong buds, larger petals, more brilliant flower color, richer fragrance, and a longer flowering period.
