How to Propagate the Bottlebrush Tree
As a unique variety in the succulent world, the bottlebrush tree is favored by flower enthusiasts for its distinctive leafless branches. Many plant lovers want to propagate new plants through cutting, but are hesitant about the winter operation. This article will systematically analyze the cutting skills of the bottlebrush tree from the principles of propagation to seasonal maintenance.
Key Steps in Propagating the Bottlebrush Tree through Cuttings
Choosing the Best Propagation Time
The end of spring to the beginning of summer, May to June, is the best time for cutting. At this time, the average daily temperature is stable between 20-25℃, and with about 65% air humidity, it can activate the cell division activity of the branches. Experimental data shows that the root formation rate can reach 92% at this time, which is 27% higher than that of greenhouse cutting in winter.
Key Points in Handling High-Quality Cuttings
When selecting the top 10cm thick stem segment, it is recommended to use a 45-degree oblique cutting method to increase the root formation area. The white juice secreted by the cut needs to be dried in the sun for 2-3 hours to form a protective film, which can effectively prevent fungal infection and increase the survival rate by 40%.
It is recommended to use a mixed matrix of珍珠岩:蛭石:粗砂=3:2:5, which has a porosity of over 35%, can retain water and avoid waterlogging. Before using, it needs to be disinfected with a 0.1% potassium permanganate solution to ensure an sterile environment.
Key Techniques for Winter Cutting
When the room temperature is below 15℃, it is necessary to equip supplementary lighting and heating equipment: 1. Turn on the full-spectrum plant light for 8 hours during the day to maintain a constant temperature of 25℃ 2. Use an electric heating bed at night, with a temperature not lower than 18℃ 3. Combine with a transparent insulation cover to maintain an 80% humidity environment
After 3-4 weeks of careful maintenance, red root points will appear at the base of the cutting. At this time, the film can be gradually removed for seedling hardening, and the cutting can be transplanted to a ceramic pot after the roots grow to 3cm, using special succulent soil and controlling the watering frequency.
After mastering the cutting rules of the bottlebrush tree, new plants can be successfully cultivated even in the cold winter. It is recommended for beginners to start with spring cutting to gain experience and gradually challenge winter propagation, enjoying the new fun of cultivating succulents.
