Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water moderately during the growing season, allowing the soil to dry slightly between waterings. Reduce watering significantly in winter, especially if grown in cooler conditions.
Ensure good drainage to prevent root rot, as this plant prefers slightly drier conditions.
Prune lightly after flowering to maintain shape and encourage bushier growth. Remove any dead or faded flower stalks. Significant pruning is usually not necessary unless the plant becomes leggy or overgrown.
Propagate from seed sown in autumn or early spring. Germination may be erratic and can be aided by a period of cold stratification. Softwood cuttings can also be taken in late spring or early summer.
Repot young plants annually or bi-annually in spring as needed. Mature plants require repotting less frequently, perhaps every 2-3 years. Use a well-draining potting mix, such as a mix for succulents or cacti.
