Why You'll Love It
Celery, while commonly known as a vegetable, is a flowering plant that brings a unique charm to any garden or indoor space. Its vibrant green stalks and aromatic foliage offer a refreshing aesthetic. Plant lovers adore Celery for its versatility – it can be grown for culinary use, adding a crisp and flavorful element to dishes, or simply appreciated for its ornamental value. The plant is relatively easy to care for, rewarding growers with a bountiful harvest or a lush, green display. It’s a great project to involve kids in and is very easy to grow. Celery’s distinct texture and subtle fragrance make it a welcome addition to any plant collection. Celery can also be grown hydroponically.
The Story
Celery (Apium graveolens) originates from the Mediterranean region, where it grew wild in marshy areas. Its use dates back to ancient times, with evidence suggesting it was used for medicinal purposes by the Egyptians, Greeks, and Romans. Initially, the plant was valued more for its seeds, which were used as flavoring and in traditional medicine. Over time, selective breeding led to the development of the larger, more succulent stalks we consume today. Celery's cultivation spread throughout Europe and eventually to the Americas. Today, it is a globally cultivated crop, playing a significant role in various cuisines and diets. Its crisp texture and mild flavor have made it a staple in salads, soups, and snacks.
Complete Care Guide
Celery thrives in full sun to partial shade, requiring at least 6 hours of sunlight daily. Water deeply and regularly, keeping the soil consistently moist but not waterlogged; never let the soil dry out completely. Plant in well-draining soil that is rich in organic matter. Fertilize every 2-3 weeks with a balanced liquid fertilizer, especially during the growing season. Maintain a consistent temperature between 60-70°F (15-21°C). Celery prefers high humidity; mist regularly or use a humidifier. Protect from frost. Harvest stalks as needed once they reach a usable size. Remove any yellowing or damaged leaves to encourage healthy growth. Regularly check for pests like aphids and spider mites, and treat promptly.
Light Requirements
Celery requires a significant amount of light to thrive, ideally 6-8 hours of direct sunlight per day. If growing indoors, place your celery plant near a south-facing window where it can receive ample sunlight. If natural light is insufficient, supplement with grow lights to prevent leggy growth and ensure robust development. Insufficient light can lead to weak stalks and poor flavor. Rotate the plant regularly to ensure even light exposure on all sides. Watch for signs of etiolation (stretching) which indicates the plant is not receiving enough light.
Seasonal Care
Spring
In spring, start celery seeds indoors or transplant seedlings outdoors after the last frost. Ensure the soil is well-draining and rich in organic matter. Provide regular watering and fertilization to promote vigorous growth. Protect young plants from pests and diseases.
Summer
During summer, celery requires consistent moisture and protection from intense heat. Water deeply and regularly, especially during dry spells. Provide shade during the hottest part of the day. Monitor for pests and diseases and treat promptly.
Fall
In the fall, continue to water and fertilize celery as needed. Harvest stalks as they mature. Protect plants from early frosts with row covers or by moving them indoors. Collect seeds from mature plants if desired.
Winter
Celery is not typically grown outdoors during winter in cold climates. In mild climates, protect plants from frost with row covers or mulch. Reduce watering and fertilization during the dormant period.
The Life of Your Celery
Seedling / Juvenile
Begin by starting celery seeds indoors 10-12 weeks before the last expected frost. Sow seeds shallowly in a seed-starting mix and keep them consistently moist. Once seedlings have developed a few true leaves, transplant them into individual pots to continue growing until they are ready to be moved outdoors.
Adolescent
As the celery plant develops, provide regular fertilization with a balanced liquid fertilizer. Ensure consistent moisture and monitor for any signs of pests or diseases. Gradually acclimate the plant to outdoor conditions before transplanting it into the garden or a larger container.
Mature
During the mature phase, the celery plant will focus on stalk development. Continue providing adequate sunlight, water, and nutrients. Harvest stalks as needed, starting with the outer ones. Monitor for bolting (premature flowering) which can occur in hot weather.
Established
After harvesting, the celery plant may produce new growth if properly cared for. Continue providing adequate water and nutrients. Remove any dead or dying foliage. If desired, allow the plant to flower and collect seeds for future plantings.
Propagation Guide
Celery is most effectively propagated from seeds, as it is typically grown for its stalks and not for extensive vegetative propagation.
1. Seed Starting: Sow celery seeds indoors 10-12 weeks before the last expected frost.
2. Germination: Keep the soil consistently moist and provide adequate light.
3. Transplanting: Once the seedlings have developed several true leaves, transplant them into individual pots.
4. Outdoor Planting: After the danger of frost has passed, harden off the seedlings and transplant them into the garden or a larger container.
While division is technically possible with established plants, it's not a common practice for celery. Stem cuttings and keiki propagation are not applicable to celery plants.
Expert Knowledge
Celery is a heavy feeder, requiring consistent fertilization throughout the growing season. Side-dressing with compost or aged manure can provide additional nutrients. Blanching celery stalks (excluding light) can result in sweeter, milder flavor. Avoid overcrowding plants to prevent disease and promote air circulation. Celery benefits from regular weeding to reduce competition for nutrients and water. Consider companion planting with onions, garlic, or marigolds to deter pests.
Troubleshooting
Yellow leaves
Yellow leaves on celery can indicate overwatering, underwatering, nutrient deficiency, or pest infestation. Check the soil moisture and adjust watering accordingly. Fertilize with a balanced fertilizer. Inspect for pests and treat promptly.
Brown leaf edges
Brown edges on celery leaves can be caused by dry air, fertilizer burn, or salt buildup in the soil. Increase humidity around the plant. Flush the soil with water to remove excess salts. Reduce fertilizer concentration.
Drooping leaves
Drooping celery leaves are often a sign of underwatering, heat stress, or root rot. Water deeply and regularly, especially during hot weather. Improve drainage to prevent root rot. Provide shade during the hottest part of the day.
Root rot
Root rot in celery is caused by overwatering and poor drainage. Ensure the soil is well-draining. Allow the soil to dry slightly between waterings. Treat with a fungicide if necessary.
Pests
Common pests of celery include aphids, spider mites, and celery leaf miners. Inspect plants regularly and treat promptly with insecticidal soap or neem oil. Remove and destroy any infested leaves.
