When is the best time to propagate roses for a high survival rate
Today, we will introduce the best time for propagating roses with a high survival rate, as well as the season and methods for rose cutting. Let's learn about it together.
Roses are cut and propagated in spring, from April to May, when the survival rate is the highest. Also known as monthly red, monthly flower, evergreen, four-season flower, and winning spring, roses belong to the Rosaceae family, Rosaceae, evergreen or semi-evergreen low shrubs. There are many ways to propagate roses, including grafting, seeding, dividing, cutting, and layering. Among them, cutting is commonly used for home potted plant propagation. Let's understand the method of rose cutting.
I. High Survival Rate Propagation Time
Roses can be propagated by cutting in spring (April to May) and autumn (August to October). When propagated in spring (April to May), the climate is warm and humid, making it easy for cuttings to survive and root, thus resulting in the highest propagation success rate. In autumn (August to October), although the climate is warm, the large temperature difference between day and night is not conducive to root growth of cuttings, so the survival rate is lower than in spring.
II. Cutting Methods
1. Bud Cutting
Take vigorous new buds from the rose plant and use them as cuttings. Make several holes in the loose and fertile substrate with a small stick, insert the cuttings into the holes 1/3 of the way, water thoroughly once, cover with plastic wrap to keep warm and moist, uncover the plastic wrap 1 to 2 times a day for ventilation, and the cuttings will root in about 15 days.
2. Stem Cutting
Take strong branches that are free from diseases and pests as cuttings, leaving 2 to 3 top leaves and cutting off the rest to reduce nutrient consumption. Apply carbendazim to the cutting's wound, let it dry in a ventilated place until the wound contracts, dip it in rooting powder, insert it into the substrate 1/3 of the way, water thoroughly, cover with plastic wrap, and place it in a sunny spot, 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 take root. Water when the surface of the substrate is slightly dry, stopping when the water渗透ates from the bottom of the substrate. Generally, water once every 7 to 10 days. After the cuttings take root, increase the watering frequency to once every 3 to 5 days. After the cutting is completed, the cutting should not be exposed to direct strong sunlight. Only after the cutting has grown for a while can it gradually be exposed to light.
