Green Ivy Often Turns Yellow Leaves
As an evergreen plant in the indoor greenery world, green ivy is deeply loved for its powerful air purification ability and tenacious vitality. But even this "lazy plant" can be troubled by yellowing leaves due to improper maintenance. In fact, several commonly found "waste waters" in daily life are natural remedies for yellow leaves.
The Scientific Basis of Watering with Waste Water
Plant Nutrition Supply Mechanism
Green ivy often turns yellow due to nitrogen deficiency. Rice washing water contains abundant amylase and vitamin groups, which can effectively supplement nitrogen, phosphorus, and potassium elements. The combination of tea polyphenols and amino acids in tea water can adjust the soil pH and promote the restoration of root absorption function.
Detailed Explanation of Rice Washing Water Fermentation Technology
Notes During Fermentation Process
Pour rice washing water into a sealed bottle with an air valve, add orange peel to eliminate odors. Place it in a 25°C environment to ferment for 15 days, and it is considered complete when the liquid is light yellow and no bubbles are produced. It is necessary to open the lid and vent daily during the fermentation process to avoid the risk of bottle explosion.
Precise Proportioning Scheme
Green Ivy Often Turns Yellow Leaves
Mature fermented liquid needs to be diluted at a ratio of 1:50, watered every 10 days in spring and autumn, and changed to every 7 days in summer. It is recommended to配合loosen the soil, dig a 3cm shallow trench along the pot edge and slowly pour it in, avoiding contact with the stem base.
Tea Water Recycling Utilization Scheme
Liquid Watering Method
Overnight tea water, after boiling and cooling, can be directly mixed with 50% clear water for watering. The tannic acid in tea soup can inhibit soil-borne diseases, especially suitable for use during the plum rain season, with noticeable effects after 2 times a month.
Solid Fertilizing Techniques
Tea dregs mixed with an equal amount of coconut bran, packed in a breathable cloth bag and buried at the edge of the potting soil. This slow-release fertilizer pack can continuously release nutrients for 3 months, while also improving the soil granule structure and preventing compaction.
Waste Water Maintenance Efficiency Enhancement Scheme
In addition to the above two common waste waters, fish tank water contains natural nitrifying bacteria, and soybean dregs water is rich in protein, both of which are excellent alternatives. It is recommended to establish a waste water rotation system, alternating the use of different types of nutrient solutions every month.
Practice shows that scientific use of domestic waste water can increase the rate of green ivy leaves turning green by 80%, and accelerate the germination speed of new leaves by 40%. Mastering these techniques of turning waste into treasure not only brings green ivy back to life but also is a vivid practice of the environmental protection concept.
