When is the Best Month to Propagate Rose bushes by Cuttings
Article Summary: An introduction to the best month for propagating rose bushes by cuttings and the timing and methods of rose cutting in the field of green plants and flowers. Let's take a look together.
Rose bushes are propagated by cuttings in spring, from April to May, when the survival rate is the highest. Also known as "Monthly Red," "Monthly Flower," "Evergreen," "Four Seasons Flower," and "Triumphant Spring," rose bushes are evergreen or semi-evergreen low shrubs of the Rosaceae family, Rosaceae genus. There are several ways to propagate rose bushes, including grafting, sowing, dividing, cuttings, and layering. Cuttings are commonly used for home potted propagation. Let's understand the method of rose bush cuttings.
I. High Survival Rate Propagation Time
Rose bushes can be propagated by cuttings in spring (April to May) and autumn (August to October). Propagation in spring (April to May) is optimal because the climate is warm and humid, making it easier for cuttings to survive and root, resulting in the highest 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, so the survival rate is lower than in spring.
II. Propagation Methods
1. Bud Cutting
Take vigorous new buds of the rose bush and use them as cuttings. Make some holes in the loose and fertile substrate with a small stick, insert the cuttings into the holes 1/3 of the way, water thoroughly, cover with plastic wrap to keep warm and moist, and uncover the wrap 1 to 2 times a day for ventilation. The cuttings will root in about 15 days.
2. Stem Cutting
Cut healthy, robust branches free of diseases and pests as cuttings, leaving 2 to 3 leaves at the top and removing the rest to reduce nutrient consumption. Apply carbendazim to the cutting wounds and let them dry in a well-ventilated area until the wounds contract. Then dip the cuttings in rooting powder and insert them into the substrate 1/3 of the way. Water thoroughly, cover with plastic wrap, and place in a sunny area, uncovering the film for ventilation every few days.
III. Maintenance Management
Whether it is bud cutting or stem cutting, it is necessary to keep the substrate moist before the cuttings root. Water when the surface of the substrate is slightly dry, stopping when water seeps out from the bottom of the substrate. Generally, water every 7 to 10 days. After the cuttings root, increase the watering frequency to every 3 to 5 days. After the cutting is completed, the cuttings should not be exposed to direct strong sunlight. Only after the cuttings have grown for a while can they gradually be exposed to light.
