Mother Of Thousands - Care Sheet

Kalanchoe daigremontiana
Updated 2025-11-24 20:42 UTC

Overview

The Mother of Thousands is a striking succulent known for its unique ability to produce dozens of tiny plantlets along the edges of its leaves. These plantlets can easily root and grow into new plants, making propagation a breeze. With its bluish-green, scalloped leaves and low-maintenance nature, this plant is a favorite among beginners and experienced growers alike. It’s important to note that while it’s easy to care for, it can become invasive if not managed properly, especially outdoors.

Light

Mother of Thousands thrives in bright, indirect light but can tolerate some direct sunlight. East- or south-facing windows are ideal indoors. Outdoors, it prefers full sun but should be protected from intense afternoon rays in very hot climates. Avoid placing it in low-light areas, as this can lead to leggy growth and fewer plantlets.

Water

Water only when the soil is completely dry. Overwatering is the most common cause of problems, leading to root rot. Use the “soak and dry” method: water thoroughly, then allow the soil to dry out before watering again. In winter, reduce watering frequency as the plant enters dormancy.

Humidity

This succulent prefers low to average humidity and does not require misting. It adapts well to typical indoor humidity levels and is not suited for high-humidity environments.

Temperature

Mother of Thousands grows best in temperatures between 18–29°C / 65–85°F. It is not frost-tolerant and should be protected from temperatures below 10°C / 50°F. If grown outdoors, bring it inside before the first frost.

Soil & Potting

Use a well-drained soil mix, such as a cactus or succulent blend with added sand or perlite. Terracotta pots with drainage holes are ideal to prevent waterlogging. Repot only when the plant becomes crowded or the soil is depleted.

Feeding

Fertilize once a year in spring with an organic slow-release fertilizer, or monthly during the growing season with a diluted balanced fertilizer. Avoid fertilizing in winter when the plant is dormant.

Repotting

Repot every few years or when the plant outgrows its container. Spring is the best time for repotting, just as new growth begins. Choose a pot only slightly larger than the current one to prevent excess soil moisture.

Propagation

Propagation is simple: collect the tiny plantlets that form along the leaf edges and place them on well-drained soil. Keep them in a warm, bright location and water lightly. Roots typically develop within 8 weeks. Once rooted, pot up individual plantlets.

Common Problems

Root Rot

Caused by overwatering. Ensure soil is well-drained and allow it to dry completely between waterings.

Leggy Growth

Occurs in low light. Move the plant to a brighter spot to encourage compact growth.

Leaf Drop

Can result from underwatering or sudden temperature changes. Water when soil is dry and keep the plant in a stable environment.

Pests

Watch for mealybugs and aphids. Treat with insecticidal soap or neem oil if infestations occur.

Toxicity & Pet Safety

Mother of Thousands is toxic if ingested and should be kept away from pets and small children. All parts of the plant contain compounds that can cause vomiting, diarrhea, and other symptoms if eaten.

Seasonal Care

During spring and summer, water regularly and fertilize monthly. In fall and winter, reduce watering and stop fertilizing as the plant enters dormancy. Protect from frost and cold drafts.
