Temperature: Highly tolerant
Light: Full sun to partial shade

Watering: Infrequent deep summer irrigations are required in Phoenix for survival.
Pruning: Like Chinese juniper, the pruning requiremnents of savin juniper are minimal; usually only training to shape if desired. That said however, manystruggle with how to maintain savin juniper as it matures and typically outgrows its planting space. Often mature savin juniper shrubs have their canopies elevated.
Propagation: Savin juniper cultivars are propagated from cuttings which generally root readily. Some of the upright cultivars are more difficult to root and are grafted, usually onto J. chinensis 'Hetzii' or J. virginiana seedling rootstock.
Disease and pests: Spider mites, juniper scale
Additional comments: Savin juniper was once more popular for use in Phoenix landscapes than it is today. There are many named cultivars such as 'Monna' from Monrovia Nursery. Some taxonomists consider Pftizer juniper (Juniperus x pfitzeriana) to be a hybrid cross between J. sabina and J. chinensis.
Medicinal note: All parts of the plant are poisonous due to several toxic compounds including ethereal oils. An oil extract from savin juniper called "sabine" is reported to have many medicinal uses.
