How to Propagate Green Ivy for Quick Rooting
Green ivy, as a common indoor ornamental plant, its propagation by cutting and potting maintenance directly affect the plant's health. Mastering scientific operation techniques can not only improve the survival rate but also promote rapid root development. This article will systematically analyze key operational steps from the selection of cutting timing to potting considerations.
Four-Step Quick Success Method for Propagating Green Ivy
Accurate Control of Golden Period
In late spring and early summer (April to June), when the ambient temperature is stable at 18-28°C, plant cell activity is at its peak. Experimental data show that during this period, the rooting speed of green ivy is faster by * times compared to winter, with a success rate increased by 65%.
Scientific Substrate Proportioning
Prepare the substrate with a ratio of珍珠岩:腐叶土:蛭石 ( Perlite: Decomposed Leaf Soil: Vermiculite) = 1:2:1, ensuring a porosity of >35%. Before use, soak thoroughly with a fungicide solution of 800 times the concentration of carbendazim to avoid fungal infection that causes cutting rot. Key indicators: EC value <0.5mS/cm, pH value 5.5-6.5.
Key Details of Cutting Treatment
Select robust stem sections with aerial roots, retaining two complete internodes. After wiping the cutting tool with an alcohol wipe, make a 45-degree diagonal cut 0.5 cm away from the node. Soak the cut end in a 500ppm indolebutyric acid solution for 10 minutes, which can shorten the rooting period by 5-7 days.
Smart Temperature Control Maintenance Strategy
After cutting, place in a diffused light environment and build a mini greenhouse to maintain 85% air humidity. Use an intermittent misting system to keep the substrate moisture at 60%-70%. Under a constant temperature of 25°C, new roots can be seen after about 15 days.
Five-Step Guide to Repotting Green Ivy
Golden Rule for Pot Selection
The new pot diameter should be 3-5 cm larger than the original pot, preferably choosing breathable containers like green mountain pots. Place a 2cm thick layer of ceramsite at the bottom of the pot, combined with a drainage hole mat to ensure a 40% increase in drainage efficiency.
Core Principles of Root Treatment
Stop watering 3 days before repotting and use the pot wall tapping method to loosen the soil. Retain 1/3 of the heart soil and use a bamboo skewer to remove compacted old soil. Trim away blackened, shriveled roots, retaining healthy white fibrous roots, with the pruning amount controlled to less than 20% of the total root mass.
Key Period Management for Acclimatization
After repotting, place in a shady and well-ventilated area for 7-10 days, gradually increasing light intensity. For the first 3 days, use foliar watering instead of irrigation, and after new roots have sprouted, apply a balanced liquid fertilizer diluted 2000 times.
Through scientific cutting and repotting operations, the root development speed of green ivy can be increased by more than 50%. It is recommended to change the potting soil every 2 years, combined with pruning in spring and autumn to maintain a beautiful plant shape. Mastering the key points of temperature and humidity control can keep green ivy in a state of vigorous growth.
