Saltwort - Key Growing Information

Saltwort planting, grown from seed; evergreen, needle-shaped leaves are edible, with a salty tang, excellent in salads.

DAYS TO GERMINATION:

Usually 7–14 days.

SOWING:

Sowing in place is recommended, from spring through midsummer: plant 1/8–¼" deep at 1–2 seeds per inch in rows 12–18" apart. Thinning isn't needed, since saltwort keeps growing even when crowded. Sow in succession for a steady harvest.
For transplants, press seed into the mix or barely cover it and water. Plant out at 3–4" tall, 4–6" apart in rows 18" apart.

LIGHT PREFERENCE:

Full sun to partial shade.

SOIL REQUIREMENTS:

Saltwort comes from Japan's salt marshes but grows well in ordinary, less salty soil.

PLANT HEIGHT:

Grows about 8–18" tall.

PLANT SPACING:

Space plants 4–6" apart.

HARDINESS ZONES:

Grown as an annual.

HARVEST:

Pick for fresh use once plants are established, and harvest promptly before stems turn woody and leaf tips get prickly.

SCIENTIFIC NAME:

Salsola komarovii
