Periwinkle cutting methods include: pruning cuttings, preparing pot soil, inserting soil, and post-cutting maintenance. The cutting time is from April to July every year. The climate environment at this time is most conducive to the roots of periwinkle. It is not suitable to take cuttings in cold weather in winter.
1. Prune cuttings: Select a strong growing periwinkle plant, select strong branches on the mother plant as cuttings, and cut the branches into several small sections, ensuring that each section has at least 3 nodes and 2 At the internode, cut off the bottom pair of leaves on the branch, leaving only the top pair of leaves on the branch.
2. Prepare the pot soil: Prepare the flower pot for planting periwinkles. You can use a disposable plastic cup with holes or a smaller flower pot and fill it with water. Clean substrate, perlite, vermiculite, coarse sand, etc. can be used as the substrate.
3. Insert the pruned periwinkle into the soil: Insert the pruned periwinkle vertically into the moist substrate, compact the substrate around the branches with your hands, and place disposable plastic cups or small flowerpots in the tray. , pour water into the tray and keep the tray always filled with water.
4. Post-insertion care: The inserted periwinkle needs astigmatism and maintenance until the periwinkle branches take root and the roots cover the plastic cup. Then transplant it into the potting soil and maintain it under astigmatism. Gradually increase the light after a week, and then gradually change to larger pots as the plants grow.
Precautions for Catharanthus roseus cuttings
After the Catharanthus roseus is transplanted, it needs to be watered immediately to keep the soil in a slightly moist state. If the soil is dry during the period, it needs to be replenished with water in time. When maintaining, care should be taken to place it in a semi-shaded and ventilated environment. The most suitable temperature is between 20-24°C, so that the rooting and survival rate of periwinkles will be relatively high.
