How to Fertilize a Salvia May Night Plant


The May Night salvia plant (Salvia x superba 'May Night' ) is a perennial flowering plant that will summon butterflies and hummingbirds into your garden. Deep purple flowers bloom atop tall spikes over fuzzy, green foliage in early to mid-summer. May Night is especially attractive in borders in cottage-themed gardens. Grow the May Night salvia in full sun in United States Department of Agriculture Hardiness zones 4 through 9. Fertilize your May Night salvia in early spring.

Step 1

Rake the soil around the salvia plants to remove any old mulch, fallen leaves and other debris.

Step 2

Sprinkle a water-soluble 10-30-10 fertilizer on the soil between the salvia plants. Apply the fertilizer at the rate suggested on the fertilizer package.

Step 3

Lightly scratch the fertilizer into the top 1/2 inch of soil with a gardening fork.

Step 4

Water the plants until the top 3 inches of soil is moist.

Step 5

Apply a fresh 3-inch layer of mulch around the base of the May Night salvia, spreading it in a 1-foot radius around the plant.
