This article will introduce you to the best method for winter rose cuttage, allowing your rose garden to bloom in winter.
Choose the right rose varietyWhen cuttage roses in winter, it is crucial to choose varieties that are cold-resistant. Varieties like 'Ruby' and 'Pink Diamond' have a higher survival rate when cut in winter. Choosing vigorous plants free from diseases and pests as cuttage materials also helps to increase the survival rate.
Collect scion1. Scion length: Generally, the tender branches of rose plants are chosen as scions, with a length of 10-15 cm being suitable.
2. Scion position: The tender branches in the middle and upper part of the rose plant are best, avoiding areas with diseases and pests.
3. Scion treatment: After collecting the scions, trim off the lower leaves with scissors, leaving only 2-3 top leaves to reduce moisture evaporation.
Disinfection and rooting hormone treatment1. Disinfection: Soak the scions in 75% alcohol or 0.1% potassium permanganate solution for 5-10 minutes to prevent bacterial infection.
2. Rooting hormone treatment: Soak the disinfected scions in 0.1% naphthylacetic acid solution for 30-60 minutes to promote rooting.
Cuttage method1. Cuttage substrate: Choose a cuttage substrate with good breathability and water retention, such as perlite or vermiculite.
2. Cuttage depth: Insert the scions into the substrate, with a depth of about 3-5 cm.
3. Cuttage density: Maintain a spacing of 3-5 cm between scions to avoid mutual shading and affecting growth.
Care and management1. Watering: Keep the substrate moist after cuttage, watering 1-2 times a day, and be careful to avoid waterlogging.
2. Temperature: When cuttage roses in winter, the temperature should be controlled between 15-20°C, which is conducive to rooting.
3. Light: Keep the scions shaded and avoid direct sunlight to prevent interference with rooting.
4. Disease and pest control: Regularly inspect the scions and deal with any diseases and pests promptly.
Post-survival management1. Transplanting: After the scions have rooted, they can be transplanted into flower pots or open ground.
2. Fertilization: During the growing period, apply a compound fertilizer once a month to provide ample nutrition.
3. Pruning: Trim away withered and diseased branches in a timely manner to maintain ventilation and light penetration of the plant.
