Cactus Grafting Tutorial with Crab Claw Orchid
Multiplying plants through grafting is an important way to enhance ornamental value, and the combination of cactus and crab claw orchid is particularly favored by horticulture enthusiasts. This inter-family grafting not only achieves innovative shaping but also enhances the plant's disease resistance. This article will provide a detailed analysis of the key points of the entire process from tool preparation to post-implantation maintenance.
Core Grafting Process
Best Timing Selection
It is recommended to carry out the process from March to June or September to October when the plants are in an active growth period. The specific operation time should be between 9-11 am when the plant cells are most active, making it easier for the vascular bundles of the rootstock and scion to fuse. If遇到阴雨天气, the operation should be postponed to avoid infection at the incision.
Scion Processing Techniques
Select three healthy stem segments from the middle of the crab claw orchid, retaining the new tip node. After wiping the tool with an alcohol swab, make a 45-degree oblique cut at the base to form a 2cm wedge-shaped surface. The incision should be kept moist, and it is recommended to complete the grafting operation within 10 minutes.
Rootstock Preparation Standards
Select a cactus with a diameter of ≥8cm and remove the top thorn cluster with forceps. Cut a 2cm deep V-shaped incision 1cm above the growth point, making sure to avoid the edge areas. Keep the tool in the incision to keep the channel open and quickly pull it out when the scion is in place.
Key Maintenance Points
Post-Grafting Management
After the grafting is complete, cover it with a transparent plastic bag to maintain humidity and place it in a scattered light environment. Avoid any watering for the first three days, and start supplementing water along the pot edge with a cotton swab from the fourth day. At night, you can open the plastic bag for ventilation for one hour to prevent the growth of mold.
Survival Judgment Criteria
Observe the scion's condition 15 days later: if the leaves are full and there is no shrinkage, it indicates success. At this point, gradually increase the duration of sunlight and supplement phosphorus and potassium fertilizer once a month. If the scion becomes soft, immediately check the incision and regraft if necessary.
Through scientific grafting, the cactus-crab claw orchid complex can achieve the ornamental effect of blooming 2-3 times a year. Mastering the three elements of temperature control, humidity management, and nutritional supply can increase the survival rate of grafting to over 85%. It is recommended to check the growth condition of the rootstock every six months and replace the aging plants in a timely manner.
