How to Plant May Night Salvia

Overview

May Night salvia, also known as Mainacht, is a perennial that is cold hardy as far north as USDA Hardiness Zone 5. The dark green, leafy base of salvia produces upright spikes of violet-blue blooms from as early as May and extending into August. Snipping off spent blooms encourages new blooms. Salvia May Night can be used as a border or grouped in the flower garden. The plant attracts bees and butterflies, and is rabbit and deer resistant. Plant May Night salvia like other sun-loving perennials.

Step 1

Choose a sunny, well-drained location for salvia May Night. The plant can grow up to 24-inches tall and wide. If planting more than one May Night, plan for about 18 inches between plants.

Step 2

Dig a hole twice as wide and deep as the May Night plant container. Place the removed soil on a tarp or in a wheelbarrow.

Step 3

Mix about 25 percent organic matter, like sphagnum peat moss or compost, with the removed soil.

Step 4

Remove the potted May Night from the container. If roots are wrapped about the outside of the root ball, use your fingers to unwrap the roots or use a utility knife to make about six cuts evenly spaced down the sides of the root ball and about 1/2 deep to free the roots.

Step 5

Backfill the hole partially so the root ball is setting on the bottom while the top of the root ball is level to the ground. Continue to backfill the hole halfway up the root ball.

Step 6

Water around the rootball to settle the soil and then finish backfilling the hole. Water again.

Step 7

Apply 2 to 3 inches of mulch, like wood chips, over the worked soil. Keep the mulch 2 inches from the stem of the plant.

Step 8

Water every seven to 10 days if there is no rainfall.
