Philodendron Pruning
Philodendron, as a common ornamental leaf plant in homes, the pruning of branches directly affects the overall shape and growth vitality. Many plant enthusiasts often encounter issues such as excessive growth of branches and yellowing leaves during the maintenance process but do not know how to proceed. This article will illustrate the pruning techniques for branches, leaves, and root systems in detail through diagrams, helping you master the scientific pruning methods.
Three Core Elements of Philodendron Pruning
Techniques for Shaping Branches
1. Main Stem Retention Principle: Select 3-5 thick main stems as the framework, and when the lateral branches exceed 20cm, use a sanitized scissor to cut diagonally 0.5cm above the bud point. Spring pruning can retain 10-15cm of main stems to promote new bud growth.
2. Disease Treatment for Branches: Check the base of branches weekly, and if brown mold spots or wilted branches are found, cut them off 2cm from the base immediately, and apply carbendazim to the wound to prevent infection. Pay special attention to areas with poor ventilation such as crossed branches and inner branches.
Leaf Maintenance Tips
For yellowing leaves, follow the principle of 'early detection and early treatment,' gently fold the base of the petiole with a pointed tweezer to remove it completely. For leaves with more than 1/3 of the area yellowed, it is recommended to remove the entire leaf, while leaves with a small amount of yellow spots can be partially pruned.
Root System Health Management
When repotting, cut off the black rotten roots and retain the healthy white roots. It is recommended to prune the roots every 2 years in conjunction with repotting, then soak in a potassium permanganate solution (1:2000) for 30 minutes, and after drying, use new soil for planting. For hydroponic plants, prune 1cm of the aging root tip monthly.
Key Points for Post-Pruning Maintenance
After pruning, place the plant in a well-ventilated area with scattered light and pause fertilization for 7-10 days. Maintain an environmental humidity of 60%-70%, and use a spray bottle to water the leaf surface morning and evening. After new buds sprout, apply a diluted 1000-fold specialized nutrient solution for ornamental leaf plants.
