Water regularly, especially during the first year, ensuring the soil is consistently moist but not waterlogged. Once established, Vitex negundo is quite drought-tolerant. Reduce watering in cooler months.

Overwatering can lead to root rot, so allow the top few inches of soil to dry out between waterings.

Prune in late winter or early spring before new growth appears. To encourage flowering and maintain shape, cut back stems by about one-third to one-half. Remove any dead, damaged, or crossing branches.

Heavy pruning can be done to rejuvenate older plants.

Easily propagated from softwood cuttings taken in late spring or early summer. Alternatively, seeds can be sown in spring, though germination may be slow and variable.

Cuttings typically root faster and produce plants true to the parent variety.

Young plants may need repotting every 1-2 years, while mature plants are less demanding. Repot in spring before new growth begins. Choose a pot that is slightly larger than the current one.

Use a well-draining potting mix. Avoid overpotting, as it can lead to waterlogged soil.
