What to Do When the Leaves of Epipremnum Aureum Turn Yellow: Does Beer Make Epipremnum Aureum Leaves Greener?
As a common houseplant, Epipremnum aureum困扰s many growers with the issue of yellowing leaves. This article systematically analyzes the causes of yellow leaves and provides solutions, as well as unveils the scientific method of using beer to nourish leaves, helping you easily cultivate shiny and green leaves.
Causes and Solutions for Epipremnum Aureum Yellow Leaves
Root Respiration Obstructed
Overwatering is a common mistake for beginners. When the soil moisture exceeds 70%, the roots may experience metabolic disorders due to lack of oxygen. It is recommended to use the bamboo skewer test: insert a bamboo skewer into the potting soil for 2 hours and observe. If it brings out obvious water stains, stop watering immediately and use a loosening tool to create 3-5 ventilation trenches around the pot wall.
Repairing Sunlight Damage
Epipremnum aureum can develop burn spots under continuous light intensity of more than 30,000 lux for 2 hours. The best solution is to move it to a position 1.5 meters away from an east-facing window and use a 50% shade cloth. Yellowed leaves can be trimmed diagonally along the leaf veins with a sterilized scissor, preserving the healthy parts to promote the growth of new leaves.
Adjusting Nutritional Imbalance
When over-fertilizing (EC value > 2.0mS/cm), perform three consecutive rinses: first, water thoroughly with clear water, then repeat after 30 minutes for two more times. It is recommended to switch to slow-release fertilizer, applying at a ratio of 1g per liter of soil every quarter.
Practical Guide to Using Beer for Leaf Care
The maltose and amino acids in beer can indeed promote chlorophyll synthesis, but it needs to be diluted strictly at a 1:50 ratio. Use a cotton cloth to wipe the front and back of the leaves once a month, making sure to avoid new tender buds. When watering, do not exceed 100ml per pot and combine with loosening the soil to ensure nutrient penetration.
Scientific care requires systematic thinking, forming a closed loop from light control to nutrient management. It is recommended to establish a care log, recording the changes in leaf color after each operation (which can be compared using an RGB color card), gradually mastering a personalized care plan.
