Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water thoroughly when the top 2-3 cm of soil feels dry. Avoid overwatering, as Euphorbia hirta prefers slightly drier conditions. Reduce watering in cooler months.
Ensure pots have drainage holes to prevent waterlogging, which can lead to root rot.
Prune to maintain shape and remove any dead or damaged stems. Pinch back the tips of young plants to encourage bushier growth. Pruning can be done anytime during the growing season. Be cautious of the white, milky sap.
Propagate from seed sown in spring or summer. Seeds can be sown directly into well-draining soil. Cuttings can also be taken in spring or summer and allowed to callus before planting in a well-draining medium.
Repot every 2-3 years or when the plant becomes root-bound. Use a well-draining potting mix, such as a cactus or succulent blend. Repot in spring before new growth begins. Handle with care, as the sap can be irritating.
