Japanese holly

Japanese holly (Ilex crenata 'Hetzii') need to be watered thoroughly every 10-14 days in the summer months and every 20-30 days in the winter months. It prefers to be watered slowly and deeply, allowing water to reach the roots. During the summer months, the soil should be allowed to dry out slightly between waterings, but ensure that it doesn’t stay dry for more than 10-14 days. During the winter months, the soil should not be allowed to dry out completely, and the plant should be watered every 20-30 days, even if it doesn't need it.

Japanese holly (Ilex crenata 'Hetzii') prefers bright sunlight, but can survive with partial shade. However, for optimal growth and flowering potential, it should receive full sun for at least 4 to 6 hours daily. It is best to give the plant morning sun and afternoon shade. Too much direct midday sun may cause the foliage to become scorched or stressed, so if your location gets really sunny and hot during the day, it is wise to provide some shade.

Japanese holly (Ilex crenata 'Hetzii') should be pruned in late winter after the blooming season. Pruning should be done lightly, only removing dead growth or trimming the foliage to desired size and shape. It is not necessary to prune this plant species heavily, as it naturally forms a tidy and rounded shape. If occasional pruning is needed, take care to prune no more than 1-third of the plant's total live foliage. This will help the plant look neat, as well as maintaining the desired size and shape.
