  1. Plant in a good location

    Plant blue salvia in a location that receives full sunlight for most of the day. Their roots do not like to stand in water, so place the plant in an area that stays moist, but not wet. Mulch around the plant to help retain moisture. The plants do best in U.S. Department of Agriculture zones 4 through 8.

  2. Water on a weekly basis

    Water blue salvia once a week. Give the plants a deep watering, soaking the soil around them to a depth of 2 inches or more to help the roots become stronger. Adjust watering as needed according to the weather, watering the plants more if there is less rainfall.

  3. Fertilize the plant

    Fertilize the salvia with a 20-20-20 fertilizer. A slow release fertilizer can be applied when the salvia is planted, or it can be applied once a month. Apply the fertilize according to the manufacturer's instructions.

  4. Deadhead the flowers

    Remove the dying flowers to encourage the production of new blooms.
