How to propagate pothos in water
Hydroponic propagation of pothos is a common method in home gardening, which is simple to operate and has a high survival rate. However, to successfully cultivate pothos plants with well-developed roots, every step from tool preparation to post-care needs careful control. This article will systematically analyze the complete process of water propagation, helping you easily master practical skills for rooting pothos in water.
Three Key Steps for Propagating Pothos in Water
Essentials for Preparing Tools and Materials
Transparent containers allow for直观 observation of root growth, and it is recommended to choose glass bottles with a diameter of over 10cm. Prepare a foam board 3cm thick as a fixed support, and use an electric soldering iron to make定位 holes with a diameter of 0.8cm. Horticultural scissors should be disinfected with alcohol to ensure smooth and non-tearing cuts.
Key Details for Processing Stem Cuttings
Select strong stems with aerial roots, retaining 3-4 internodes. Use a 45-degree oblique cut method to increase the water absorption area and let the cut dry to form a semi-transparent callus. It is recommended to choose indole butyric acid formula for the rooting powder, as the powdered form is easier to attach than the liquid.
Scientific Hydroponic Operation Standards
Water treatment should be done by sunning for 3 days in advance, maintaining the temperature difference between water and room temperature within 2℃. The water level should be controlled to submerge 1/3 of the stem, and the foam board should have a 0.5cm gap reserved to ensure air circulation. It is recommended to change 1/3 of the water every week to avoid frequent water changes that stimulate the plant.
Advanced Techniques for Post-Propagation Care
Lighting and Temperature Control Plan
Initially, place in a diffused light environment, maintaining a light intensity of 2000-3000Lux. Keep the temperature within the golden range of 20-28℃, and in winter, keep it more than 2 meters away from heating equipment. Humidity management can be achieved through the bagging method, maintaining 80% relative humidity.
Nutrient Supplement Timing Control
No nutrient solution should be added before the roots form. When the white roots reach 3cm, add 0.5ml of hydroponic-specific liquid fertilizer per liter of water. Supplement with维生素B12 solution once a month to enhance the root's anti-corrosion ability.
Through 20-30 days of systematic care, the pothos roots can reach the transplantation standard. When the secondary roots exceed 5 and the length reaches 8cm, it can be transferred to soil culture or continue with hydroponics. Regular pruning of old roots can maintain root vitality, and proper lighting can make the leaves look glossy, creating a healthy and beautiful indoor green plant landscape.
