How to propagate the Catharanthus roseus cutting
This article introduces the propagation methods of Catharanthus roseus cutting and the cultivation knowledge of Catharanthus roseus, with specific details as follows:
Catharanthus roseus cuttings should be taken from April to July, cutting 10cm long healthy branches, removing leaves, sterilizing and drying the wounds, and preparing water or a mixture of peat soil and river sand soil that has been dried and left for 1-2 days. For water propagation, the water level should be below 1/2 of the branch, changing water every day for a week can root; for soil propagation, the depth should be 1/3, watering and controlling temperature, and it can root in 15-20 days.
1. Branch Treatment
In spring and summer, from April to July, cut 10cm long healthy branches from the Catharanthus roseus mother plant, remove the excess leaves, leaving only the top pair of leaves, then apply carbendazim to the cut surface for sterilization, and place it in a ventilated area to let the wound dry.
2. Prepare Substrate
Actually, the propagation methods of Catharanthus roseus cuttings are divided into water propagation and soil propagation, so it is necessary to prepare suitable substrates for different cutting methods. For water propagation, prepare tap water that has been dried and left for about 1-2 days, while for soil propagation, prepare a mixture of peat soil and river sand at a ratio of 1:1, and disinfect to avoid carrying bacteria.
3. Branch Cutting
For water propagation, insert the branches directly into the hydroponic container, with the water level not exceeding half of the branch, and then place it in a shaded and well-ventilated area for maintenance. For soil propagation, insert 1/3 of the branch into the soil, slightly compact the soil and water it to moisten, keeping the soil moist.
4. Post-maintenance
For water propagation, change the water once a day to prevent murky water from breeding bacteria and making it difficult to root. After about a week of maintenance, the roots will grow, and then plant them in the soil and keep them in a shaded area for 7 days to let them adapt and survive, then maintain normally, and the cutting is successful.
For soil propagation, place the plant in a well-ventilated and sunny position, allowing it to receive plenty of scattered light, and keep the growing environment temperature at about 20-24°C, watering every 2-3 days to keep the soil moist. Generally, after about 15-20 days, the cuttings will also root.
The above is a specific introduction on how to propagate Catharanthus roseus cuttings and the propagation methods of Catharanthus roseus, hoping to bring some flower knowledge to green enthusiasts.
