Reasons and Solutions for the Yellowing of Coin Grass Leaves
The round and cute leaves of coin grass suddenly turning yellow can be a big concern for many plant enthusiasts. This common issue actually hides the growth code of the plant. By mastering the key maintenance skills, one can restore the vibrant green posture of coin grass. We will analyze the causes of yellowing leaves from three core dimensions and provide practical solutions.
Strategies for Improper Substrate Maintenance
Soil Improvement for Terrestrial Plants
When soil compaction and poor drainage are detected, it is recommended to replace it with nutrient-rich soil containing humus. During the operation, retain 1/3 of the protective soil, mix with perlite and pine needle soil to enhance breathability, and place the plant in a shady area for 3-5 days after repotting.
Water Quality Management for Aquatic Plants
Turbid water can cause root rot and should be replaced weekly with sun-exposed tap water. During the high-temperature summer months, add 1-2 drops of chlorine remover, and in winter, the frequency of water change can be extended to every 10-15 days, keeping the water level covering 2/3 of the roots.
Correction Plan for Nutritional Imbalance
Emergency Treatment Techniques for Fertilizer Burn
Immediately rinse the potting soil with water three times after fertilizer burn occurs, and cut off the blackened roots. For aquatic plants, thoroughly replace the nutrient solution, pause the addition of nutrients for one month, and then resume light and frequent fertilization after new leaves sprout.
Scientific Fertilization Cycle Recommendations
Apply diluted foliage plant-specific fertilizer (2000 times) every 20 days during the spring and autumn growing seasons, and stop fertilizing during the winter dormancy period. The amount of nutrient solution added each time should be controlled to 1/2 of the amount marked on the bottle, combined with a monthly foliar spray of potassium dihydrogen phosphate.
Golden Rules for Light Adjustment
Gradual Adaptation to Light Intensity
Plants that have been in the shade for a long time should gradually increase light exposure, extending direct sunlight by 1 hour each day, transitioning to full sunlight within two weeks. In the summer, 30% of the strong light should be shaded at noon to avoid leaf burn.
Reasonable Use of Supplemental Lighting
During indoor maintenance in winter, set up a plant growth light 40-50 centimeters away from the leaves, with 6-8 hours of daily exposure. Be sure to rotate the pot regularly to ensure even light exposure from all directions.
By systematically adjusting the maintenance methods, coin grass usually shows significant improvement within 2-3 weeks. The key is to establish an observation-diagnosis-intervention maintenance cycle, regularly checking the substrate moisture, leaf condition, and new growth points. It is recommended to wipe the leaf surface with a damp cloth monthly, which not only removes dust but also makes it easier to detect abnormalities, allowing this auspicious foliage plant to remain vibrant and healthy for a long time.
