1500 Tall Utah Celery Seeds

Start Tall Utah Celery about 10 weeks before the last spring frost if you want thick stalks before heat arrives. Sow seed shallowly in flats or trays and keep the mix evenly moist, because celery seed is small and stalls fast if the surface dries out. Under warm conditions, germination usually takes 14–21 days. Once seedlings reach about 6 inches tall plant them outside 6–8 inches apart so each plant has room to build stalk mass.

Utah Celery seeds require full sun in cool conditions, though in hotter areas a little afternoon shade can help keep growth steady. Work in compost before planting, because celery is a hungry crop and thin soil gives you thin stalks. Celery is not a drought tolerant plant, so keep the root zone consistently moist rather than swinging from dry to soaked. 

Once plants settle in, keep weeds down and feed the row well enough. If you want a milder, sweeter bite, protect them from sunlight for about two weeks before harvest. Mature plants can produce stalks up to 12 inches long and roughly 3 inches in diameter under good conditions. Harvest comes in about 100 days, so make sure to cut them in time. The leaves are useful too — dry them for seasoning, or chop them fresh into soups, salads, and stocks.
