You carefully insert the spike into the ground and place a glass bottle filled with water in the spike. The spikes are made of clay. This is how it works: When the potting soil is dry, the water passes through the spikes into the soil until it is sufficiently watered. Clay has the property of storing water and releasing it gradually. This keeps the soil permanently moist. The spikes are ideal for watering during holidays.
