How to grow mother of millions
Overview
Mother of millions (Kalanchoe delagoensis) is a succulent herb grown for its striking tubular, grey-green foliage and prolific production of plantlets. It is a gap-filler in garden beds but is highly invasive; it must be contained to prevent spread into natural areas.
Varieties
- Kalanchoe delagoensis — The standard species with tubular grey-green leaves and orange-red flowers, widely available in Australian nurseries.
Soil Preparation
Prefers a free-draining, sandy or loamy soil with a pH of 6.0–7.5. Add coarse sand or perlite to improve drainage. Avoid heavy clay or water-retentive mixes. No need for rich organic matter; a lean, gritty mix is ideal.
Growing Guide
Plant in full sun in free-draining, sandy or gravelly soil. Space plants 30–50 cm apart to allow air flow and reduce humidity. Do not overwater; let the soil dry completely between waterings. Remove plantlets as they appear to prevent self-seeding. In cooler zones, grow in a pot and move to a warm spot during frost.
Care
Feed sparingly with a balanced liquid fertiliser once in spring. No pruning needed; remove spent flower stalks and plantlets to control spread. Repot every 2–3 years if container-grown, refreshing the soil mix.
Companion Planting
Grow with other succulents like Echeveria, Sedum, or Agave that share similar low-water needs. Avoid planting near native bushland or grasses that could be overtaken by plantlets. Best kept in a container or isolated bed.
Common Pests & Risks
Mealybugs and scale can infest leaf axils; treat with a cotton swab dipped in alcohol. Aphids may appear on new growth; blast off with water or use neem oil. Root rot from overwatering is the main disease; ensure free-draining soil and avoid wetting leaves.
Troubleshooting
Yellow leaves: overwatering or poor drainage — let soil dry out and improve drainage. Brown leaf edges: sunburn or low humidity — move to partial shade or increase air flow. Leggy growth: insufficient light — move to full sun. Plantlets not rooting: too dry — keep soil slightly moist until roots form. White powdery spots: powdery mildew — improve air circulation and avoid overhead watering.
