Plant in full sun, in moist, well-drained soil. It tolerates most conditions but avoid waterlogged sites. Mulch in spring to conserve moisture and suppress weeds. In frost-prone areas, protect young plants from cold winds.
Prune in late winter or early spring to maintain shape and encourage vigorous flowering. Remove any dead, damaged, or crossing branches. Cutting back hard every few years can rejuvenate older plants and stimulate more prolific summer blooms.
Regular watering in dry periods helps establish young plants, but once established, Vitex is drought-tolerant. Fertilise in early spring with a balanced feed to support flowering and healthy growth.
