Water consistently, especially during establishment and dry periods. Aim for about 2. 5 cm of water per week. Ensure good drainage to prevent waterlogging.

Mulching helps retain soil moisture and suppress weeds, reducing the need for frequent watering.

Prune in late winter or early spring before new growth begins. Remove dead, damaged, or crossing branches. Thin out crowded areas to improve air circulation and fruit yield.

For younger plants, focus on establishing a strong central leader.

Propagate by softwood cuttings taken in early summer or hardwood cuttings in late autumn. Seeds can be sown in autumn, requiring a period of cold stratification.

Layering is also an effective method for increasing the plant population.

Repotting is generally not applicable to mature, in-ground Viburnum trilobum. Container-grown specimens should be repotted every 2-3 years into a larger container using well-draining potting mix, typically in late winter or early spring.
