The ideal growing conditions for this shrub are between 40 and 90 degrees Fahrenheit. Protect the plant from extreme cold by providing some cover if temperatures dip below the minimum threshold.
- Pruning
Prune Japanese Privet 'Rotundifolium' to shape it, remove any dead or damaged branches, and encourage bushier growth. The best times for pruning are late winter or early spring, before the onset of new growth. It is a relatively fast grower, so annual pruning may be required to maintain a desired size and shape.
- Cleaning
As needed
- Soil
Wax leaf privet thrives in well-draining soil enriched with organic matter and prefers a pH between 6.5 to 7.5. A mix of garden soil, compost, and perlite or sand can work well, ensuring nutrients and adequate drainage.

- Life cycle
Ligustrum japonicum 'Rotundifolium', commonly known as Japanese privet, begins its life cycle with seed germination, which requires a warm stratification period to break dormancy. Following germination, the seedling stage involves initial root and shoot development as the plant establishes itself. The vegetative stage is characterized by robust leaf and branch growth, with the plant developing its signature rounded foliage and reaching maturity. The reproductive stage comes into play as the mature shrub produces fragrant white flowers, generally in late spring to early summer, followed by pollination and fertilization. Seed development ensues, with the production of purple to black berries containing seeds that are dispersed by birds and other wildlife. The life cycle can complete when the plant potentially reaches a senescence phase, characterized by a natural decline in growth and reproductive ability with age.
- Propogation
Propogation time
Spring-Early Summer
The Japanese Privet 'Rotundifolium', is commonly propagated through semi-hardwood cuttings. This method involves taking cuttings from the plant during the late summer, as this is the time when the current year's growth has begun to mature and harden slightly. Cut a 4-6 inch (10-15 cm) length of semi-hardwood, which should include several leaves or leaf buds, and remove the leaves from the lower half of the cutting. Dip the cut end into rooting hormone powder to encourage root development. Plant the treated cutting into a pot filled with a mixture of peat and perlite or sand, ensuring that the bottom half where the leaves were removed is buried. Maintain a humid environment by covering the pot with a plastic bag or placing it in a propagator and keep it in indirect light until roots develop, which typically takes several weeks. Once the cutting has rooted, it can be transplanted into a larger pot or directly into the garden.
