Why "Watering When Dry and Wet"
In home potted plant care, watering is a critical operation that determines the life or death of the plant. The principle of "watering when dry and wet" is a classic watering rule, especially for special plant groups like succulents, which embodies the wisdom of scientific care. This method simulates the alternating dry and wet conditions of the native environment, ensuring plant growth while avoiding the risk of waterlogging.
The Scientific Care Principle of "Watering When Dry and Wet"
Soil Moisture Balance Mechanism
The dry-wet cycle stimulates the reorganization of soil pore structure, allowing oxygen and water to alternate and infiltrate the roots. When the top 2-3 centimeters of soil are dry, the deep capillary water can still maintain root vitality, and supplementing water at this time can activate the germination of new roots. Experimental data shows that succulents using this method have 40% more root growth than those in continuously moist environments.
Root Characteristics of Succulents
Succulent roots have unique water storage tissues, and excessive moisture can cause cell wall rupture. The intermittent water supply mode of "watering when dry and wet" keeps the roots healthy in the cycle of water absorption, storage, and rest. Observations indicate that strictly following this method can reduce the root rot rate by 75%.
Advanced Techniques for Dry-Wet Judgement
Visual and Tactile Double Check
When the topsoil turns white and there is a 0.5cm gap at the edge of the pot, a bamboo skewer can be inserted into the soil layer to test the moisture. When there are no clay particles attached to the bamboo skewer at the center of the potting soil, and the weight of the pot is reduced by 1/3, it is the best time to water.
Seasonal Adjustment Tips
In spring and autumn, follow the regular cycle. In summer, when it's hot, water in the evening. In winter, extend the interval to 15-20 days. After special weather conditions, check the soil: delay watering after continuous rainy days, and water 1-2 days earlier after dry and hot wind weather.
Mastering the essence of "watering when dry and wet" lies in understanding the dynamic balance between plants and the environment. This method is not only applicable to succulents but also effective for plants like pothos and kaffir lilies with fleshy roots. By establishing a scientific watering rhythm, it can help plants develop stronger, healthier roots with better resistance, truly achieving the art of watering and care.
