chastetree

Chastetree is typically a drought tolerant species, however optimal growth and health can be achieved by providing it with adequate watering. It should be watered deeply about once a week, allowing the soil to become completely saturated and then allowing it to dry out before the next watering. During periods of hot, dry weather, increase watering to twice a week. In the cold winter climate, where temperatures may remain lower for extended periods of time, water only when the soil is completely dry.

Chastetree (Vitex agnus-castus 'Shoal Creek') grows best in full sun, meaning that it should receive at least 6 hours of direct sunlight each day. Chastetree prefers periods of full sun in the morning and afternoon, though it needs some midday shade, especially in warmer climates. Although chastetree will tolerate partial shade, it may not bloom as abundantly in such environments. As such, it’s best to find a spot that gets mid-morning sunlight and shade in the hotter afternoon hours.

Chastetree (Vitex agnus-castus 'Shoal Creek') should be pruned in the late winter or early spring before new growth begins. Prune back the long arching branches to roughly 2-thirds of their length. This will encourage a more lush, compact habit, and remove any unsightly, damaged growth. It is also important to remove any crossing branches to increase air circulation and decrease the risk of fungal issues. After the main pruning, it is also a good idea to tidy up any further branches that may appear too long or thin, or those that are dead, damaged, or diseased. It is best not to prune too heavily as this can adversely affect flowering.
