Gardenia can be propagated in various ways, among which cutting propagation is the most common method. Here, we will share with you the method to propagate gardenias with quick root growth, allowing you to easily reproduce beautiful gardenias.
Choose the Right Time for CuttingThe best time for gardenia cutting is generally in spring and autumn when the temperature is suitable for the growth of gardenias. Spring cuttings can be done from March to April, and autumn cuttings can be done from September to October.
Select Healthy Gardenia BranchesChoosing healthy gardenia branches is key to successful cutting propagation. You should select branches that are vigorous and free from diseases and pests, usually 10-15 cm in length, with 2-3 leaves left on the branch.
Handle the Branches1. Cutting: Cut the bottom of the branch diagonally to increase the water absorption area and improve the success rate of cutting.
2. Disinfection: Use 75% alcohol or 0.1% potassium permanganate solution to disinfect the branches to prevent the invasion of germs.
3. Drug Treatment: Soak the disinfected branches in a rooting hormone solution, such as ABT rooting powder or indole butyric acid, for generally 12-24 hours.
Cutting1. Prepare the cutting substrate: A mixture of perlite, vermiculite, and river sand can be used as the cutting substrate, in a ratio of 1:1:1.
2. Cutting Depth: Insert the processed branches into the substrate, about 3-5 cm deep.
3. Cutting Density: The density of cutting should not be too high, generally maintaining 3-5 plants per square centimeter.
Care Management1. Watering: After cutting, keep the substrate moist but avoid excessive watering to prevent branch rot.
2. Light: In the early stage of cutting, shade appropriately to avoid direct sunlight, and gradually increase light after the branches have rooted.
3. Temperature: Maintain a room temperature of 20-25℃ during the cutting period, which is conducive to root growth of the branches.
4. Fertilization: About one month after cutting, apply diluted compound fertilizer to promote branch growth.
Precautions1. Choose healthy branches and avoid using branches with diseases and pests.
2. When handling branches, pay attention to disinfection and drug treatment to prevent the invasion of germs.
3. Keep the substrate moist after cutting and avoid excessive watering.
4. Shade appropriately to avoid direct sunlight.
5. Pay attention to temperature and light, which are beneficial to root growth.
The method of quick root growth for gardenia cutting is simple and easy to perform. As long as you master the cutting skills and care management, you can easily propagate beautiful gardenias. We hope the above methods are helpful to everyone, and wish you all successful cuttings!
