The Old Yew Plant Shop Watering Bulb

The porous terra cotta cone acts as a semi-permeable membrane, allowing water to seep into the soil only as the plant dries out. Unlike plastic globes that can dump water too quickly, this clay-based system provides a more consistent, measured release tailored to your plant's actual hydration needs.

It is excellent for most thirsty indoor plants, but it may not be suitable for succulents, cacti, or other varieties that require dry soil cycles. Always check your specific plant's water requirements before installing the bulb.

The clear glass reservoir makes it easy to monitor water levels at a glance. When you see the glass is empty, simply lift it from the clay cone and refill it under the tap.

Yes, the terra cotta cone is designed to stay in the soil, while the glass reservoir can be removed for refilling. We recommend cleaning the cone occasionally to prevent mineral buildup and ensure the pores remain open for proper water flow.

The ten-day duration is an estimate based on average indoor conditions. Factors like high heat, low humidity, or a very thirsty plant may cause the reservoir to empty faster, so it is wise to check your plants before leaving for an extended trip.
