Vallaselu

Vallaselu is a term derived from Estonian that describes the act of self-watering a plant using a system that relies on a water reservoir. This method is particularly useful for houseplants and in situations where regular watering might be difficult to manage, such as during vacations. The core principle involves a container of water placed below the plant's soil. A wick, typically made of absorbent material like cotton, nylon, or felt, connects the reservoir to the soil.

The wick draws water up into the soil through capillary action as the soil dries out. This process ensures that the plant receives a consistent and appropriate amount of moisture, preventing both overwatering and underwatering. The rate of water uptake is dependent on the plant's needs and the ambient humidity. Vallaselu systems can be simple, involving a pot with a built-in reservoir, or more complex, using separate containers and wicks. This technique is considered a passive form of irrigation, meaning it doesn't require pumps or active control once set up. It's a popular method among plant enthusiasts for its efficiency and its ability to maintain plant health with minimal daily intervention.
