How to improve the survival rate of grafted Disocactus
Do you know these? Introduction to the succulent plant Disocactus, how to improve the survival rate of grafted Disocactus, let's take a look together.
Many plant enthusiasts enjoy grafting plants like Disocactus and Opuntia to improve their survival rate, the following points should be noted during grafting:
1. Timing of grafting should be appropriate
Grafting should be done when both the scion and rootstock are growing vigorously with sufficient sap, usually when the temperature is between 20-25°C. In northern regions, it is roughly from April to June or September to October. Grafting during spring to early summer yields the best results.
2. Rootstock selection should be suitable
For grafting Disocactus, the generally chosen rootstock is the heavenly bamboo or flat cactus, with flat cacti commonly used as the rootstock for grafting Disocactus.
3. The position of grafting should be appropriate
When using heavenly bamboo as the rootstock, it should be planted in a 20 cm pot and cut horizontally 30 cm above the pot surface. During grafting, make three cuts on the three corners of the heavenly bamboo, all reaching the pith. Then take the top 2-3 sections of the Disocactus stem, remove the convex main vein and the outer skin on both sides, shaping it like a duck bill to expose the vascular bundles. The cut should be smooth and immediately insert into the rootstock cut until it reaches the xylem. After joining, immediately hold the joint with your hand, secure with a wooden clip or use a pin or thorn to prevent the scion from slipping out. In this way, one scion can be grafted on each of the three corners.
4. Post-joining management should be scientific
To prevent excessive water loss from the scion affecting survival, after grafting, the scion can be covered with a transparent plastic bag. Do not tie the lower end of the plastic bag tightly. After grafting, place it in a cool and well-ventilated area, keeping the potting soil slightly moist, and generally do not water. After 7 days, if the scion still remains upright and fresh, it indicates that it has survived. At this point, the plastic bag can be gradually removed, and the wooden clips or pins can be removed after 2-3 weeks. After 4-5 weeks, it can be gradually moved to a semi-shaded environment for cultivation and gradually transitioned to normal fertilizer and water management.
The above is a detailed explanation of how to improve the survival rate of grafted Disocactus, for everyone's reference and suggestions!
