How to propagate roses with a high survival rate
The following is a detailed introduction for netizens on how to propagate roses with a high survival rate and the technical points of rose cutting, which will be introduced by the editor for netizens.
Roses are cut in April to May of spring when the survival rate is the highest. Also known as monthly red, monthly flower, Changchun flower, seasonal flower, and Shengchun, roses are evergreen or semi-evergreen dwarf shrubs of the Rosaceae family, Rosaceae genus. There are many ways to propagate roses, including grafting, sowing, dividing, cutting, and layering. Among these, cutting is commonly used for home pot propagation. Let's understand the method of rose cutting.
Ⅰ. High Survival Rate Cutting Time
Roses can be cut in April to May of spring and August to October of autumn. Cutting in April to May of spring, when the climate is warm and humid, makes it easier for cuttings to survive and root, resulting in the highest success rate. Cutting in August to October of autumn, although the climate is warm, the large temperature difference between day and night is not conducive to root growth, so the survival rate is lower than in spring.
Ⅱ. Cutting Methods
1. Bud Cutting
Take vigorous new buds from the rose and use them as cuttings. Make several holes in the loose and fertile substrate with a small stick, insert the cutting into the hole 1/3 of its length, water thoroughly, cover with plastic wrap to keep warm and moist, uncover the plastic wrap 1 to 2 times a day for ventilation, and the roots will form in about 15 days.
2. Stem Cutting
Take robust branches that are free from diseases and pests as cuttings, leaving 2 to 3 top leaves and removing the rest to reduce nutrient consumption. Apply carbendazim to the cutting wound, let it dry in a well-ventilated area until the wound contracts, then dip it in rooting powder, insert it into the substrate 1/3 of its length, water thoroughly, cover with plastic wrap, and place it in a sunny area, uncovering the film for ventilation every few days.
Ⅲ. Maintenance Management
Whether it's bud cutting or stem cutting, it's necessary to keep the substrate moist before the cuttings root. Water when the surface of the substrate is slightly dry, stopping when water渗透ates from the bottom. Generally, water every 7 to 10 days. After the cuttings root, increase the watering frequency, usually every 3 to 5 days. After cutting is completed, the cuttings should not be exposed to direct strong sunlight and can gradually be exposed to light after a period of growth.
