Care:
Care: Grow Caradonna salvia flowers in a location with full sun and with a well-drained soil. Although drought-tolerant once established, a moderate amount of water must be supplied to young plants.
Disease: plants are generally free of most serious disease and pest problems. However, there is some care required as the plants have some susceptibility to powdery mildew, rust, botrytis, and leaf spot.
Propagation: If you deadhead Caradonna salvia flowers (that is, remove
the spent blooms), the plants will flower all summer long. Fertilize the
plants by working compost or manure tea into the soil.
