How to propagate a stick tree for high survival rate
As a unique existence among succulent plants, the stick tree is deeply loved by gardening enthusiasts for its emerald green, leafless coral-like shape. Mastering the correct propagation techniques is the key to cultivating healthy plants, among which the cutting method, as the mainstream propagation method, directly affects the survival rate with its operational details. This article will systematically analyze the three core methods of propagating stick trees.
Complete process analysis of stick tree cutting propagation
Golden time selection
Although cuttings can be made throughout the year, statistics show that the success rate can reach 92% in May to June. At this time, the daily average temperature is stable at 20-25℃, combined with about 66% air humidity, which can accelerate the formation of callus.
Key points for branch treatment
Choose strong branches with a top diameter ≥0.5cm, keeping 3 stem nodes is the best. The cut should be coated with charcoal powder for sterilization treatment, and dried in the sun for 48 hours until the cut completely scabs over, which can effectively avoid 90% of the risk of bacterial infection.
Scientific matrix proportion
Using the golden ratio of perlite: vermiculite: river sand = 3:2:5, the measured root germination rate increases by 40% under this ratio. The matrix pH should be controlled between 6.0-6.5, and it needs to be sterilized with high-temperature steam before use.
Intelligent maintenance management
Use intermittent spraying to keep the matrix slightly moist, and control the light intensity between 5000-8000lux. It is recommended to use intelligent temperature control equipment to maintain a temperature difference environment of 28℃ during the day and 18℃ at night, and new roots can be seen in about 20 days.
Comparison of other propagation methods of stick trees
Seed propagation technology
Choose seeds collected in the same year, with a germination rate of about 65%. Use a seedling tray method, with a covering soil thickness of 0.2cm, maintaining a constant temperature of 25℃, usually seedlings appear within 14-21 days. Special attention should be paid to preventing猝倒 disease during the seedling stage.
Tissue culture propagation technology
Professional laboratories often use a combination formula of MS medium + 0.5mg/L NAA, with a proliferation coefficient of up to 4.8. It requires four stages: external explant disinfection, primary culture, secondary proliferation, and root culture, with a total duration of about 90 days.
By comparison, it can be seen that the cutting method has the advantages of simple operation, low cost, and high survival rate. It is recommended that enthusiasts first master the cutting technique, while understanding other propagation methods as knowledge reserves. Regularly observe the plant's condition and adjust the maintenance strategy in combination with seasonal changes to cultivate a beautifully shaped stick tree.
