When is the best time to propagate roses by cutting
Summary: Tips on the best time to propagate roses by cutting and the methods for rose cutting and timing for green plant maintenance, which will surely help you. Let's learn about it together!
Roses are best propagated by cutting in spring, from April to May, when the survival rate is the highest. Also known as monthly red, monthly flower, evergreen flower, seasonal flower, and winning spring, roses are evergreen or semi-evergreen low shrubs of the Rosaceae family. There are many ways to propagate roses, including grafting, sowing, dividing, cutting, and layering. Among these, cutting is commonly used for home potted plant propagation. Let's learn about the methods for propagating roses by cutting.
I. High Survival Rate Cutting Time
Roses can be propagated by cutting in spring (April to May) and autumn (August to October). Propagating in spring (April to May) has a warm and humid climate, making it easier for cuttings to survive and root, resulting in the highest success rate. In contrast, although the climate is warm during autumn (August to October), 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 plant and use a small stick to make holes in the loose and fertile substrate. Insert the cutting into the hole about 1/3 of its length, water thoroughly, cover with plastic wrap to keep warm and moist, and uncover the wrap 1 to 2 times a day for ventilation. The cutting will root in about 15 days.
2. Stem Cutting
Take sturdy branches that are free from 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's wounded area and let it dry in a well-ventilated area until the wound contracts. Then dip it in rooting powder and insert it into the substrate about 1/3 of its length. Water thoroughly and cover with plastic wrap, placing it in a sunny area. Uncover the film for ventilation every few days.
III. Maintenance Management
Whether using 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渗透ates from the bottom. Generally, water once every 7 to 10 days. After the cuttings root, increase the watering frequency to every 3 to 5 days. After cutting, the cuttings should not be exposed to direct sunlight. Only after a period of growth can they gradually be exposed to light.
