Water: Drought-resistant varieties of big red sage require minimal watering during summer, needing water only in drought. In contrast, tender varieties and young plants need about 2.5 cm (1 inch) of water every 7-10 days to prevent soil from completely drying out.

Fertilize: In rich or clay soils, big red sage needs no fertilizer; in poor soils, it benefits from a little compost. When planting, slow-release fertilizer can be added cautiously to avoid excessive growth that may lead to flopping.

Pruning: Big red sage requires minimal pruning, mainly of dead stems in early spring to encourage new growth. Light shaping enhances bushiness and air circulation. Removing spent flower spikes promotes continuous blooming, optimizing health and aesthetics. Consult guides for species-specific care adjustments.
