watering
Chaste tree (Vitex agnus-castus 'Colonial Blue') requires moderately moist, well-drained soil. Water it deeply and slowly to encourage deep root growth. During the growing season, water this shrub regularly. Provide 1 to 2 inches of water each week. Allow the top inch or 2 of soil to dry out before watering again. During the hot summer months, water your chaste tree every 7 to 10 days. In the winter months, water it only rarely, as it's in a dormant stage. If there is no rainfall for more than 2 weeks consecutively, you may need to give it supplemental watering.
sunlight
Chastetree (Vitex agnus-castus 'Colonial Blue') needs full sunlight in order to grow and thrive. This plant species typically needs a minimum of 6 hours of sunlight each day to produce its best blooms. If grown indoors, it may need supplemental light to reach the desired amount of 6 hours. The best time of day to provide this sunlight is between 10am - 4pm, as this is when the sun is at its peak.
pruning
Chastetree should be pruned in late winter or early spring before new foliage appears. Lightly prune the shrub with shears by cutting back the branches that are overlong or have sparse foliage. Remove branches that are dead, damaged or diseased. It is best to avoid heavy pruning as chastetree won’t recover if pruned too severely. If needed, prune the chastetree to keep its shape and encourage growth.
