Is the scarless grafting of Cereus peruvianus good
If you want to know whether the scarless grafting of Cereus peruvianus is good and understand the correct fertilization methods for Cereus peruvianus, the following article will provide you with detailed answers.
Introduction: Cereus peruvianus, also known as "Peacock Orchid," is native to Mexico. Based on its growth habits and shape, it is classified as a perennial evergreen epiphyte in the Cactaceae family. The flowering period is in the midsummer season, and when the bright and colorful flowers bloom, they emit a fresh and elegant aroma through the stem joints that resemble a command arrow, creating a good decorative effect indoors.
We propagate Cereus peruvianus through stem cutting, but by the second year of the flowering period, there are no signs of flower buds developing. In fact, it is not that any step in the cutting propagation is wrong, but that propagating Cereus peruvianus through cutting requires more than three years of cultivation and care before it enters the stage of mature reproductive organs. If we switch to grafting, choosing a robust root system and adaptable stock, as well as stem segments that have reached the flowering stage as scions, then it is possible to achieve flowering the following year. This can also improve the weak root system and the growth defect of easy water loss in the stems and leaves of Cereus peruvianus. Today, let's explore how to propagate Cereus peruvianus through grafting, not only to speed up flowering but also to improve growth defects.
One, What is scarless grafting of Cereus peruvianus?
Propagating Cereus peruvianus through grafting is a relatively important asexual propagation method for flowering plants, which is also known as "transplanting flowers and grafting wood" among plant enthusiasts. It involves selecting the tender stems of the current year's Cereus peruvianus as scions and grafting them onto closely related cactus stocks. Through professional grafting techniques and proper care management that promotes healing, the two are combined into one, creating a grafted seedling with independent life, which is the grafting propagation of Cereus peruvianus.
Two, What are the advantages of grafting Cereus peruvianus?
Grafting Cereus peruvianus not only brings the advantage of rapid flowering but also many growth advantages. For example, it can improve the growth defect of underdeveloped roots, increase the survival rate of propagation, and produce more vibrant and full flowers. It can benefit later care management and provide a rich viewing experience. This is because when we graft, we certainly choose to overcome the poor growth genes brought by cutting propagation.
Three, What is the best season for grafting Cereus peruvianus?
Cereus peruvianus is native to the tropical regions of the Americas and has adapted to a warm and humid climate, resulting in a cold-sensitive growth gene. A temperature range of 15-30 degrees Celsius is considered suitable for growth. The season that meets this suitable temperature is only in early summer (May to June). The temperature in early summer not only gradually rises but also retains the moist air of spring, which perfectly meets the warm and humid growth gene. Grafting Cereus peruvianus in early summer can rely on the climate to promote the fusion of the scion and stock, thereby increasing the survival rate of grafting propagation.
Additionally, although the overall temperature and humidity in early summer (May to June) can promote the fusion of the stock and scion, it is important to avoid grafting during rainy periods. High humidity during rain can easily lead to bacterial infections at the grafting site, thus reducing the survival rate of grafting propagation. Therefore, to increase the survival rate of grafting propagation, it is necessary to choose温和的晴天 and avoid bacterial infection.
Four, How to graft Cereus peruvianus?
How to propagate Cereus peruvianus through grafting? In fact, among other flowering plants, grafting in the Cactaceae family is one of the easier ones. Since the stems and leaves of Cereus peruvianus are flat and thick, it is suitable to use the cleft grafting method. Although the grafting method is simple, an immature technique or a blunt knife can easily cause gaps at the grafting site, reducing the survival rate. Therefore, before grafting, we need to understand the related knowledge of grafting and prepare a sharp knife, etc.
1. Selection of Stock
What is stock? It is the flowering plant used to graft the scion of Cereus peruvianus. The choice of stock is a key factor in whether the grafting can survive. Choosing a flowering plant from the Cactaceae family as the stock brings the advantage of strong affinity and close genetic relationship, speeding up the fusion of the stock and scion and avoiding the rejection of plant cells in the later stage, thus increasing the survival rate of grafting.
Based on years of grafting experience, robust and adaptable cacti with thick roots can be chosen as the stock for propagating plants in the Cactaceae family. This not only meets the criteria of strong affinity and close genetic relationship but also improves the weak root system of Cereus peruvianus; thus increasing the value of grafting survival and bringing early flowering and vibrant flowers. When choosing cacti, we should avoid weak plants or those infected with pests and diseases and choose strong, healthy plants for grafting.
2. Selection of Scion
Although the stock is a key factor in the survival of Cereus peruvianus grafting, the importance of the scion should not be underestimated. If old branches are used as the scion, the grafting site will not heal and the purpose of flowering the following year will not be achieved, thus reducing the survival rate and value of grafting. We need to choose tender branches from the current year, which can bring strong regeneration ability and allow cells to quickly flow into the stock for growth, while also promoting flowering the following year.
When selecting the scion, we need to choose healthy tissue with abundant sap inside the stem. Tissue that meets these requirements generally has strong regeneration ability, promoting fusion between the stock and scion and increasing the survival rate of grafting.
3. Grafting Method
A. First, prepare the scion
We use scissors to quickly cut a 7 cm long tender stem of Cereus peruvianus as the scion, then trim the base of the scion into a wedge shape. This wedge shape must be straight and not biased, relying on one side to facilitate fusion with the vascular tissue (beginners should wait until the stock is prepared before cutting the scion).
Caution: After cutting the scion of Cereus peruvianus, it should be placed in a shady and well-ventilated area for备用. However, the placement time should not be too long, ensuring that it is in a state of sap overflow before grafting to facilitate healing and avoid scion withering.
B. Next, prepare the stock
Why do we first cut the scion? Because we can shape the stock according to the shape of the scion. Using a sharp knife, quickly flatten a cactus leaf to act as the base for the scion, matching the size of the scion's base, and then make a 1.5 cm deep cut to match the shape of the scion.
C. Finally, perform the grafting
When the scion and stock are oozing sap, quickly insert the Cereus peruvianus scion into the cactus stock, ensuring a 100% fit between the scion and stock, and then use the cactus needle to secure them. This completes the grafting process of Cereus peruvianus. The reason why cacti in the Cactaceae family are easy to graft is that no soil, plastic tape, or rope is needed for grafting.
Caution: After grafting the cactus, remember to perform消毒的养护管理. Since both the scion and stock have wounds, without disinfection and杀菌 care, bacterial infections can occur, leading to a reduced survival rate of grafting. It is recommended to spray a 1000-fold diluted solution of carbendazim once and ensure indoor ventilation.

Five, How to care for Cereus peruvianus after grafting?
After completing the grafting of Cereus peruvianus through the above steps, we still need to promote the fusion of the stock and scion through scientific and reasonable care management to increase the survival rate of grafting propagation. So, let's talk about how to care for Cereus peruvianus after grafting.
1. Light: Cereus peruvianus enjoys a sunny growing environment and is a flowering plant that requires a lot of light. Apart from needing some shading in the summer, it requires full sun in other seasons. If placed in a well-lit position immediately after grafting, it can hinder the fusion of the stock and scion. Therefore, it should be placed in a shady and well-ventilated indoor area for about ten days, and only moved to an outdoor area with soft light after the grafting site has healed, until it has survived to receive normal light care.
2. Temperature: Cereus peruvianus prefers a warm and comfortable growing environment and is very sensitive to low temperatures. A temperature range of 15-30 degrees Celsius is considered the growing stage for the plant. However, for plants that have just been grafted, the temperature should not be too high or too low and should be maintained around 18 degrees Celsius to assist in healing the grafting site and achieving the fusion of the stock and scion.
In addition, always observe the humidity of the grafting care environment. Since both Cereus peruvianus and cacti prefer dry growing environments, the soil should not be too moist during the grafting process, as this can easily lead to root rot and result in grafting failure; plus, the grafting site cannot get wet, so only ground spraying can be used to increase humidity, but not too much, just slightly moist.
In summary, propagating Cereus peruvianus through cutting is difficult to achieve flowering the following year. To speed up flowering, we can choose to propagate through grafting. This not only brings a higher survival rate of propagation but also allows for the enjoyment of beautiful flowering scenery the following year. At the same time, it can improve the weak root system of Cereus peruvianus, thus enhancing the growth ability of the grafted seedlings and bringing a stronger viewing experience.
