Succulents are drought-tolerant plants that store water in their leaves, stems, or roots, allowing them to thrive in arid environments with infrequent rainfall. The common question of how often to mist these plants often stems from a misunderstanding of their biological needs. This article clarifies the appropriate method and frequency for watering succulents to ensure their long-term health and growth.
Why Misting is Detrimental to Succulents
The short answer to how often you should mist a succulent is never, as this practice is actually harmful. Misting only provides superficial moisture and increases the humidity immediately surrounding the plant. Succulents are naturally adapted to dry climates and low humidity, making this added moisture unnecessary and counterproductive.
Water droplets sitting on the leaves or stem, especially near the crown, create an environment that encourages fungal growth and bacterial infections. This standing moisture can quickly lead to stem or leaf rot, which is a common cause of death for these plants. Furthermore, misting does not deliver water to the root system where it is needed for hydration.
The plant’s root system is designed to absorb large amounts of water during rare, heavy rainfall events. When only the topsoil is lightly moistened by misting, the plant develops shallow, weak roots that remain close to the surface. This prevents the development of the deep, healthy root structure needed to sustain the plant during dry periods.
The Full Soak and Dry Watering Method
The correct approach to watering succulents is called the “soak and dry” method, which mimics their natural experience of heavy, infrequent rain. This technique involves thoroughly saturating the soil until water flows freely from the pot’s drainage holes. The deep watering encourages the formation of robust, deep roots that can support the plant through long periods of drought.
Succulents must be planted in a container with an adequate drainage hole and a fast-draining soil mix. A suitable mix includes inorganic materials like pumice, perlite, or coarse sand, which prevent compaction and excessive moisture retention. This composition allows for rapid percolation and ensures that the roots are not suffocated by waterlogged conditions.
After the deep soak, any water that collects in the drainage saucer must be discarded within 30 minutes. Allowing the roots to sit in standing water leads to root rot, the most common cause of succulent failure. The goal is to fully hydrate the root ball and then let the soil dry out completely before the next watering.
Reading Your Succulent’s Need for Water
Determining the appropriate time to water should be based on the plant’s condition, not a fixed calendar schedule. The fundamental rule is to wait until the soil is completely bone dry all the way to the bottom of the pot. Check this by inserting a finger or a wooden skewer deep into the soil; if it comes out clean and dry, the soil is ready.
Beyond the soil check, the succulent itself will display physical cues when it is thirsty and prepared for another soaking. A well-hydrated succulent will have firm, plump leaves that are resistant to a gentle squeeze. When the plant begins to use its stored water, the leaves will appear slightly wrinkled, thinner, or rubbery to the touch.
Watering frequency depends on environmental factors, including light intensity, temperature, and air circulation. Succulents in bright, warm locations will require water more often than those in cooler, shadier spots. The plant’s water needs will also change between its active growing season and its dormant period, making observational watering the most reliable practice.
