【High-quality terracotta clay】Plant watering devices are made of high-quality terracotta clay, durable, have good permeability and are weather-resistant. The porous material prevents water from flowing out of the bottles when the plant watering spikes are inverted and allows the water to pass through slowly. The wetter the soil, the slower the seepage. 【Precise and efficient】When the potting soil is dry, this soil spike will gradually drip precisely. When the soil is sufficiently moist, the dripping will stop automatically. You can also add liquid plant food to stimulate growth. 【Easy to use】Watering sticks for potted plants are designed for use with long-neck bottles such as wine and beer bottles.
