Self-watering pots for easy care of aroid plants
Self-watering pots consist of an inner pot with holes and a transparent water reservoir around it. Through capillary action, the soil absorbs the amount of water that the plant needs. In each pot there is a string that runs from the inner pot down into the reservoir. The string acts as a wick that transports the water to the soil at the right rate, which means that the plant always has access to the right amount of moisture. This provides more even moisture and reduces the risk of over- or under-watering.
Sizes and materials
The pots come in different sizes to suit both small and larger aroid plants. They are made of durable plastic and have a transparent interior that makes it easy to see the water level. This means you always know when it's time to refill.
Soil that is best suited
For aroid plants, an airy soil mix works best. A combination of potting soil, coconut fiber, bark and perlite or pumice is ideal. This allows the roots to get both oxygen and moisture without standing in wet soil. Using a dense soil that holds a lot of water can lead to oxygen deficiency and root rot. An airy mix, on the other hand, allows the pot to function optimally and the plant to feel its best.
Plants that thrive in self-watering pots
They are especially good for aroid plants such as Monstera, Philodendron, Alocasia, Anthurium and Syngonium. Hoya and other plants that like even but not wet moisture can also thrive. Self-watering pots are a great choice for people who travel a lot or often forget to water because the system allows the plant to sustain itself for several days or weeks depending on size and consumption.
Water refilling
The water reservoir is filled through a hole on the side or from above until the level reaches the mark in the pot. It is important not to fill above the maximum level as this will cause the soil to become too wet. How often you need to fill depends on the size, species, temperature and light conditions of the plant, but as a rule a well-filled reservoir can last for one to two weeks. It is always better to let the reservoir empty completely before refilling than to constantly fill to the top. This improves the oxygen supply to the soil and the roots develop stronger.
Benefits at home
Self-watering pots make it easy to succeed with slightly more sensitive aroid plants because they provide a stable moisture level in the soil. The plant grows more evenly, the leaves become larger and the risk of damage from incorrect watering is reduced. They are also practical for those who want lush greenery but do not have the time to water as often.
