Watering Globes and Clay Cones: Vacation Watering for Houseplants
Heading off on vacation and worried about your plants? Watering globes and clay cones are the simple, power-free solution for keeping houseplants watered while you’re away. No electronics, no tubing, no power needed β just a water reserve that’s released into the soil gradually. In this article, we explain how these systems work, which products are worth buying, and which plants they suit best.
How Do Watering Globes Work?
The principle couldn’t be simpler: a glass globe filled with water is fitted with a thin tube and pushed into the soil. Thanks to capillary action and the vacuum inside the globe, water is released only when the soil is dry. If the soil is already moist, the water stays in the globe. The system regulates itself β brilliantly simple, with no moving parts. Depending on the globe’s size and the plant’s needs, one fill lasts anywhere from 3 to 14 days.
Clay Cones: The Porous-Material Alternative
Clay cones work in a similar way but use a porous terracotta cone inserted into the soil. A thin tube connects the cone to a water reservoir (a bucket or bottle). The dry clay draws water from the reservoir and releases it into the surrounding soil β again, self-regulating. Clay cones can deliver larger volumes of water than glass globes and also work well for bigger container plants.
Which Plants Are They Suited For?
Watering globes and clay cones work best on plants with moderate water needs: spider plants, pothos, philodendron, monstera, ferns, and peace lilies. They’re less suitable for cacti and succulents, which prefer to stay on the dry side, as well as plants with very high water needs, such as bog plants. One tip: move the plant to a slightly shadier spot before fitting the watering globe β this further reduces water consumption.
Conclusion
Watering globes and clay cones are the perfect low-tech solution for vacation care. For roughly a small cost per plant, you can secure the water supply for one to two weeks. For longer absences or larger collections, it’s worth switching to an automatic irrigation system with a timer. Your plants will reward you with healthy, green growth.
