Esschert Design Plant Watering Spikes

These spikes are specifically designed to fit standard wine bottles with a neck diameter of approximately 1.75 inches. While other bottles might fit, the seal may not be secure enough to regulate water flow correctly.

Because the ceramic is porous, you will notice the water level in the bottle slowly decreasing over time as your plant absorbs moisture. If the water level drops too quickly, the soil may be too dry or loose; if it doesn't drop at all, the soil might be oversaturated.

These spikes are primarily designed for indoor use. While they can technically be used outdoors, evaporation rates and soil conditions vary significantly, which may cause the water to drain much faster than it would indoors.

Yes, for the best results, you should bury the porous ceramic portion of the spike completely into the soil, leaving only the opening for the bottle neck exposed. This ensures the capillary action functions correctly across the entire surface area of the stake.

Yes, the capillary action system releases water only as the soil dries out, which helps prevent the waterlogged conditions often caused by traditional watering. However, it is still important to monitor your plant's specific moisture needs, as this system is a supplement rather than a complete replacement for plant care.
