Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Artemisia annua prefers consistently moist soil but can tolerate occasional dryness. Water thoroughly when the top inch of soil feels dry. Avoid overwatering, which can lead to root rot.
Reduce watering frequency in cooler months when the plant's growth slows down.
Pruning is mainly done to shape the plant and encourage bushier growth. Pinch back young plants to promote branching.
Older plants can be cut back in late spring or early summer to maintain size and prevent them from becoming too leggy or woody.
Artemisia annua is easily propagated from seeds sown indoors in early spring or directly outdoors after the last frost. It can also be propagated from stem cuttings taken in late spring or early summer.
Cuttings root readily in moist, well-draining soil.
Repotting is rarely necessary for Artemisia annua as it is often grown as an annual or short-lived perennial. If grown in a container and it becomes root-bound, repot in spring into a slightly larger pot with fresh, well-draining potting mix.
