Cultivation & History (source) |
About Celery Celery, celeriac, and lovage are three closely related plants that are grown similarly. Celery is grown for its stems, celeriac for its large, rounded, strong-flavored root (good in soups), and lovage is an herb grown for its leaves and stems (which are also good in soups and other foods). All three plants can be grown from seed in the garden, but they grow slowly and are more likely to be successful if seedlings are grown indoors to a height of about 12 cm (5 in) and then transplanted. All must be watered regularly and harvested before frost. When to Plant Celery seed is usually started indoors about 10 weeks before it is time to set the plants outdoors - that is, after the soil is warm and the air temperature settled. The seed is minute and finicky, and is started in much the same manner as African violet seed, in closed containers to keep seedlings moist. Soak seeds overnight to help germination. Transplant seedlings outside when they are 4-6 inches tall and night temperatures don't fall below 40F. Water plants before they are transplanted. Some gardeners who have a long frost-free autumn season can seed a late winter crop directly. How to Plant In rows 2 feet apart; with 6 - 8 inches between plants. When seedlings are set out they need a quick start, which is usually provided by watering the plants with a water-soluble, high-nitrogen fertilizer. Since the plants have fine, almost hair-like roots, use a heavy mulch to keep down weeds. How to Harvest |
