Kalanchoe plants are popular succulents known for their vibrant blooms. While generally easy to care for, proper watering is crucial for their health and flowering. This guide explains how to water your Kalanchoe correctly.
Understanding Kalanchoe’s Unique Watering Needs
Kalanchoe plants are succulents, storing water in their thick leaves and stems. This adaptation helps them endure drought in arid environments. Overwatering is their primary vulnerability, quickly leading to root rot and plant decline.
Allow the soil to dry completely between waterings. To check, insert your finger two inches deep; if it feels dry, the plant needs water. A moisture meter also provides an accurate reading.
How to Water Your Kalanchoe
When it is time to water your Kalanchoe, employ a thorough “soak and drain” technique. Water the plant deeply until you observe water freely draining from the bottom of the pot. This ensures that the entire root ball receives adequate moisture.
Proper drainage is extremely important for Kalanchoe health. Always use pots with drainage holes to prevent water from accumulating around the roots, as standing water can quickly lead to root rot. After watering, ensure no excess water remains in the saucer beneath the pot; promptly empty any collected water. Bottom watering, where the pot absorbs water from a tray, is an alternative method that can encourage strong root growth and prevent overwatering from the top. When watering, avoid splashing water directly onto the leaves to help prevent potential fungal issues.
Factors Affecting Watering Frequency
There is no universal watering schedule that applies to all Kalanchoe plants, as several environmental and plant-specific factors influence how often they require water. The season plays a significant role, with plants generally needing more frequent watering during their active growing periods in spring and summer. Conversely, during the dormant winter months, watering should be significantly reduced.
Light exposure impacts water needs; Kalanchoe in brighter light or direct sun consume water more quickly. Higher temperatures and lower humidity increase evaporation, requiring more frequent watering. Smaller pots dry faster than larger ones, and porous materials like terracotta promote quicker evaporation than plastic. Larger Kalanchoe have greater water demand than smaller specimens.
Troubleshooting Watering Issues
Recognizing the signs of improper watering is important for maintaining a healthy Kalanchoe. Overwatering often manifests as yellowing, mushy leaves, or a soft, wilting stem despite the soil being wet. In severe cases, stem or root rot may occur. If you suspect overwatering, immediately cease watering, allow the soil to dry completely, and inspect the roots for rot. If root rot is present, carefully remove the plant, trim any soft, brown, or black roots, and repot into fresh, well-draining soil.
Conversely, an underwatered Kalanchoe will display wrinkled, shriveled, or brittle leaves. The foliage may appear lackluster, and growth can become stunted. The soil will be noticeably dry and possibly compacted. To address underwatering, water thoroughly using the soak and drain method until water drains from the pot’s bottom. Leaves should rehydrate and regain their plump appearance within a day or two.
