Tall Utah - Organic Celery Seeds

Start celery indoors about 10–12 weeks before the expected last spring frost. The seeds are tiny and slow to germinate, often taking two to three weeks, so celery should be started earlier than most vegetable transplants.

Set hardened plants outdoors near the last frost once the weather is reasonably settled. Celery tolerates cool conditions, but prolonged exposure to cold after transplanting can cause premature flowering instead of good stalk formation.

Press the seeds onto the surface of moist seed-starting mix and cover them only lightly. Keep the surface evenly moist and provide gentle warmth until seedlings emerge.

Once plants are established, give them bright light and steady moisture. Move crowded seedlings into individual containers if needed, then harden them gradually before planting outdoors. Space plants about 8–12 inches apart, with enough room between rows for airflow and harvest. Celery transplants successfully, but young plants need careful handling and should never be allowed to dry out.

Choose a site with full sun to light afternoon shade and deep, well-drained soil enriched with finished compost. Celery needs more consistent moisture than most garden vegetables and becomes tough or stringy when growth is interrupted.

Water deeply whenever rainfall is lacking and mulch once the soil has warmed to hold moisture, suppress weeds, and protect soil structure. Maintain balanced fertility throughout the long growing season, but avoid sudden flushes of soft, overly lush growth.

Harvest individual outer stalks once they are large enough to use, leaving the center intact so the plant can continue growing. For a full head, cut the entire plant near soil level when the stalks are crisp and well filled.

Celery is commonly ready about 75–90 days after transplanting, depending on the variety and growing conditions. Harvest before the outer stalks become coarse or stringy.
