Water: Every 5 to 10 days
Mature size: 30 to 150 cm
Growth rate: Medium
Hardiness: USDA 5 to 10

Care

Plant in a spot with excellent drainage to prevent root rot. Deadhead spent flower spikes to encourage a second flush of blooms. Watch for powdery mildew if the air circulation is poor.

Watering: Allow the top few centimeters of soil to dry out completely between waterings.
Feeding: Apply a balanced liquid fertilizer once every two months during the active growing season.
Pruning: In early spring, cut herbaceous types back hard to promote bushy growth. On shrubby types, trim lightly above healthy buds and avoid cutting into old bare wood, which often does not regrow.
Repotting: Repot when the plant becomes root bound or the soil structure breaks down.
Soil: Sandy, loamy, well draining
Soil pH: 6.0 to 7.5
Temperature: -10 to 35°C
Humidity: 30 to 60%
Drought tolerance: High
Lifespan: Perennial, typically 3 to 5 years

Signs it needs repotting

Roots growing out of the drainage holes.
Water draining through the pot too quickly.
Stunted growth during the active season.

Safety

People: Most ornamental salvias are non-toxic, but some species can cause irritation if ingested in large quantities.
Pets: Most species are non toxic to cats and dogs, though some varieties may cause mild stomach upset if ingested in large quantities.
Children: The plant is generally safe, but keep small children away from stems to avoid potential skin irritation.
Contact allergens: The foliage can cause mild skin irritation in sensitive individuals due to essential oils.
Airborne allergens: Pollen can trigger seasonal allergies in some people during peak bloom.
Edibility: Only specific culinary varieties like Salvia officinalis are safe for consumption.

Stem Cuttings

Take a 10 centimeter cutting from non-flowering growth.
Remove the lower leaves.
Place in moist potting mix until roots develop.

Plant Salvia with other drought-tolerant perennials to create a low-maintenance, pollinator-friendly garden bed.
