What are the timing and methods for grafting Disocactus ackermannii?
Today's mini experience sharing: the small green plant maintenance experience of when and how to graft Disocactus ackermannii, let's take a look together!
Disocactus ackermannii is deeply loved by people because of its long blooming period and bright flower colors. However, direct cultivation often has problems such as weak roots and easy lodging. Grafting can effectively improve these defects and enhance the plant's resistance and ornamental value. Mastering the correct timing and methods is the key to success. This article will systematically introduce the technical points of grafting Disocactus ackermannii.
### - - Choosing the Best Grafting Time - - Grafting Disocactus ackermannii needs to be done when the plant is in an active growth period, as the formation of callus is fast and the survival rate is high at this time. The specific timing is influenced by the following factors:
#### - - Seasonal Recommendations - -
- - Spring and autumn are the most suitable: In spring (March to May), the temperature is stable at 15-25°C, and Disocactus ackermannii ends its dormancy and enters the growing period; in autumn (September to October), the temperature is cool, avoiding the wound rot caused by the high temperature in summer.
- - Avoid extreme weather: High temperature and humidity in summer can easily lead to the rot of scions, while low temperature in winter inhibits the formation of callus.
#### - - Weather Conditions - -
- - Choose overcast days or early morning and evening periods for operation to avoid direct sunlight causing water loss. It is best to have no rain for 3 days after grafting to prevent rainwater from infecting the wound.
### - - Choosing and Treating the Rootstock - -
#### - - Common Rootstock Types - -
- - Cactaceae: The most common is the Trichocereus (triangle pillar), which has a developed root system and strong drought resistance.
- - Leaf cactus: Good affinity, but slower growth.
- - Grass ball: Suitable for small Disocactus ackermannii grafting, but with weaker support.
#### - - Rootstock Pretreatment - -
- - Control water intake one week in advance to reduce sap flow during grafting.
- - Choose a healthy and disease-free rootstock with a diameter of more than 1.5cm to ensure sufficient nutrients.
### - - Standards for Choosing Scions - -
#### - - Branch Requirements - -
- - Choose 1-2-year-old healthy leaves, 8-10cm in length, with 2-3 nodes.
- - Avoid using old or tender buds, as old branches have poor activity and tender buds are prone to dehydration.
#### - - Scion Treatment - -
- - Disinfect the knife with alcohol, cut the base of the scion into a bilateral wedge shape (about 1cm long) to increase the contact area of the cambium layer.
- - Avoid touching the cut surface after cutting to prevent contamination.
### - - Detailed Grafting Steps - -
#### - - Method 1: Top Splitting Method (Suitable for Trichocereus Rootstock) - -
1. - - Rootstock Treatment - -
- - Make a longitudinal cut 1.5-2cm deep at the top of the rootstock.
- - The cut must be smooth to avoid roughness affecting adhesion.
2. - - Inserting the Scion - -
- - Insert the wedge-shaped part of the scion into the rootstock cut, ensuring that at least one side of the cambium layer aligns.
- - Use clips or plastic wrap to secure it to prevent displacement.
#### - - Method 2: Lateral Grafting Method (Suitable for Columnar Rootstock) - -
1. - - Rootstock Cut - -
- - Make a 45-degree diagonal cut to the woody part of the rootstock, matching the length of the scion's wedge shape.
2. - - Fixing Techniques - -
- - Wrap the scion with grafting tape after insertion to prevent moisture from entering the cut.
### - - Key Post-Grafting Maintenance - -
1. - - Environmental Control - -
- - - Humidity Management - -: Maintain air humidity above 70% for the first 7 days, can use bags to keep moisture, and ventilate for 1 hour daily.
- - - Light Regulation - -: Place in a scattered light area, and gradually increase light exposure after 2 weeks.
2. - - Watering and Fertilizing - -
- - No watering is allowed within 10 days after grafting, and then water when dry.
- - After surviving (about 1 month), apply diluted phosphorus and potassium fertilizer to promote healing.
3. - - Survival Judgment - -
- - Successful sign: The scion does not wilt within 2 weeks, and new buds sprout. If it turns black, it needs to be grafted again in time.
### - - Common Problems and Solutions - -
- - Wilted Scion - -: Often due to insufficient humidity, re-bag to keep moisture.
- - Rotting Rootstock - -: Rain or excessive watering before the cut heals, need to cut off the rotting part and disinfect.
- - Slow Growth - -: Check if the cambium layers are aligned or if the rootstock has insufficient nutrients.
### - - Conclusion - - Grafting Disocactus ackermannii focuses on the timing, cambium layer alignment, and post-grafting moisture retention. By following the above methods, the survival rate can reach over 90%. The grafted plants have denser blooms and significantly extended lifespan. It is recommended for beginners to practice cutting skills on ordinary cacti first, and then proceed with formal grafting.
