How to grow Mealycup Sage (annual blue salvia) in Tucson & the low desert
Watering
Best grown as a COOL-SEASON annual in the low desert: set out transplants in fall (Oct-Nov) or late winter (Feb-Mar) for fall-through-spring color; it struggles in peak June-August heat. Water deeply and let the top inch dry between waterings - it is fairly drought-tolerant once established and dislikes constantly wet soil.
Fertilizer & nutrients
Light feeder; a balanced or higher-phosphorus bloom fertilizer monthly enhances flowering. Avoid heavy nitrogen, which produces floppy growth at the expense of spikes.
Pruning & care
Shear back spent flower spikes to keep it blooming and tidy; cut back hard if it gets leggy. (Technically a tender perennial, often short-lived/grown as an annual in Tucson.)
Notes
Important Tucson nuance: unlike scarlet salvia, mealycup sage performs as a cool-season annual here - plant it in fall or late winter, not for summer. It can short-lived-perennialize in milder microclimates.
