Growing Celery in Maine
Maine’s cool climate provides excellent conditions for growing celery, especially during the spring and fall. Celery is a slow-growing, cool-season crop that benefits from Maine’s shorter growing season.
Best Time to Plant
In Maine, it’s best to start celery indoors 10-12 weeks before the last frost date, which typically falls between mid-May and early June. Transplant seedlings outdoors once the soil has warmed to at least 50°F, usually by late May or early June. For fall planting, you can start seeds indoors in late May and transplant them in mid to late July for a late-season harvest that extends into early fall.
Soil and Watering Needs
Celery prefers rich, loamy soil with plenty of organic matter, so it’s essential to amend the soil with compost before planting. Celery requires consistent moisture to thrive, which can be a challenge in Maine’s drier summer months. Water regularly to keep the soil evenly moist, as celery is susceptible to drought stress. Applying mulch around the plants helps retain moisture and regulate soil temperature.
Sunlight and Temperature
Celery needs full sun to partial shade, and in Maine, where summers are generally mild, full sun is ideal. Daytime temperatures between 60-70°F are perfect for celery growth, making the cooler spring and early fall ideal times to grow celery. Too much heat can cause the plant to bolt or become tough and bitter, so avoid growing celery during the hottest part of the summer.
Harvesting Tips
Celery takes about 85-120 days to mature after transplanting. You can begin harvesting when the stalks are about 8-12 inches tall. Cut the outer stalks first, and allow the inner ones to continue growing. Maine’s cooler weather helps celery maintain its crisp texture and sweet flavor.
