How to Grow White Sage
Salvia apiana
White sage is a drought-tolerant evergreen shrub native to California and Mexico with silvery-white aromatic leaves used for smudging. Hates wet conditions and needs full sun, excellent drainage, and sandy or gravelly soil. In the UK, grow in a greenhouse or against a very sheltered south-facing wall only as it will not survive wet winters outdoors. Water very sparingly once established.
Yearly Lifecycle
Care Requirements
Light
Full sun, maximum heat
Requires full sun and as much heat as possible. Native to arid California chaparral. In the UK a south-facing greenhouse or conservatory provides the best conditions.
Watering
Very sparingly, almost none in winter
Extremely drought-tolerant once established. Water only when the soil is bone dry. No water at all in winter. Overwatering is the primary killer.
Fertilizing
None needed
Adapted to poor, mineral soils. Fertilizing produces soft, disease-prone growth that is uncharacteristic of the plant. Leave unfed.
Pruning
Light shaping only
Minimal pruning needed. Remove dead or damaged stems in spring. Can be lightly shaped after flowering but avoid hard cuts into old wood.
Growing Tips
Drainage is everything
Plant in pure grit, sand, or gravel-heavy mix. Even a small amount of water retention in the root zone will cause rot. Raised beds or containers with mineral substrate work best.
Greenhouse or south wall only
In the UK, white sage cannot survive outdoors through winter. A cold greenhouse with no supplemental watering in winter is ideal. A very sheltered south-facing wall may work in mild coastal areas.
Do not overwater
White sage is adapted to desert conditions. Water only when completely dry and even then sparingly. More plants are killed by kindness than neglect.
