Best Time for Rose Bush Propagation by Cuttings
In-depth explanation for netizens who are concerned about the best time for rose bush propagation by cuttings and the small knowledge of flowering plant care, let's follow the editor to take a look!
Rose bushes are propagated by cuttings in April to May of spring when the survival rate is the highest. Also known as "Monthly Red," "Monthly Flower," "Evergreen," "All-season Flower," and "Victory Spring," rose bushes belong to the Rosaceae family and are evergreen or semi-evergreen low shrubs. There are many ways to propagate rose bushes, including grafting, sowing, dividing, cuttings, and layering. Among these methods, cuttings are commonly used for home potted plant propagation. Let's get to know the method of propagating rose bushes by cuttings.
Ⅰ. High Survival Rate Time for Cuttings
Rose bushes can be propagated by cuttings in April to May of spring and August to October of autumn. Propagating in April to May of spring, with a warm and humid climate, makes it easier for cuttings to survive and root, thus resulting in the highest success rate. However, 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 of the cuttings, resulting in a lower survival rate compared to spring.
Ⅱ. Cutting Methods
1. Bud Cutting
Select vigorous new buds of the rose bush and break them off by hand as cuttings. Make several holes in the loose and fertile matrix with a small stick and insert the cuttings into the holes 1/3 of their length. Water thoroughly once, cover with plastic wrap to keep warm and moist, and uncover the plastic wrap 1 to 2 times a day for ventilation. The cuttings can root in about 15 days.
2. Stem Cutting
Choose strong branches that are free from diseases and pests as cuttings, retaining the top 2 to 3 leaves and cutting off the rest to reduce nutrient consumption. Apply carbendazim to the cutting's wound and let it dry in a well-ventilated area until the wound contracts before dipping it in rooting powder. Insert the cutting 1/3 into the matrix, water thoroughly, and cover with plastic wrap, placing it in a sunny spot. Uncover the film for ventilation every few days.
Ⅲ. Maintenance Management
Whether it's bud cutting or stem cutting, it's necessary to keep the matrix moist before the cuttings root. Water when the surface of the matrix is slightly dry, stopping when the water渗透ates from the bottom of the matrix. Generally, water once every 7 to 10 days. After the cuttings 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 a period of growth can it gradually be exposed to light.
