How to Identify When a Chlorophytum Comosum Is Short of Water
As a common indoor ornamental plant, the watering management of Chlorophytum Comosum directly affects its growth condition. Mastering scientific methods to determine water deficiency can effectively prevent issues like yellow leaves and rotten roots. This article will systematically explain four practical detection techniques, combined with the plant's growth characteristics to help plant enthusiasts accurately grasp the timing of watering.
Physical Testing Method to Determine Soil Moisture
Tap and Listen to Identify Water Content
Tap the middle section of the pot with a wooden stick. A crisp echo indicates the soil is completely dry (water content < 15%), and the potting soil separates to form gaps; a dull sound shows sufficient water (water content > 40%). It is recommended to adjust the judgment criteria according to the season, maintaining 20%-30% water content in spring and autumn.
Weighing Comparison Method
Weight the pot before and after watering, recording the difference as a reference for water content. Terra cotta pots lose about 35% of their weight when dry, and plastic pots lose about 25%. It is suggested to create a watering log, noting the time and weight changes for each watering, gradually establishing a personalized care database.
Sensory Observation Method for Comprehensive Judgment
Finger Test for Soil
Insert the index finger 2-3 centimeters into the soil, feeling the temperature and moisture with the finger's pad: slightly cool and moist (water content 25%-35%) can temporarily delay watering; dry and warm (water content < 15%) requires immediate watering. Clean the fingers before testing to avoid introducing pathogens.
Leaf Condition Monitoring
Healthy leaves should stand upright at a 45-degree angle. When short of water, the leaf angle increases to over 60 degrees, and the leaf surface luster decreases by 20%-30%. This method should be combined with other detection means to avoid mistaking wilt caused by diseases as water deficiency.
By comprehensively using the above methods, a three-dimensional monitoring system can be established. It is recommended to check every 3-5 days in spring and autumn, and observe twice a day in summer. When watering, ensure the water temperature is the same as the room temperature, and use the immersion pot method to ensure the soil absorbs water evenly. Regularly use bamboo sticks to loosen the soil to maintain root aeration.
