Cutting method1. Cutting material: Select healthy branches free of diseases and pests as cutting materials, usually using the current year's semi-lignified branches.
2. Cutting: Cut the branches into segments 10-15 cm long, with the top cut diagonally and the bottom cut horizontally to increase the water absorption area.
3. Disinfection treatment: Soak the cut branches in a potassium permanganate solution for 30 minutes to prevent infection by pathogens.
4. Cutting substrate: Select a cutting substrate with good breathability and water retention, such as perlite or vermiculite.
5. Cutting depth: Insert the branches into the substrate, with a depth of about 1/3 to 1/2 of the length of the branch.
