Celery is a cool-season crop known for its crisp, flavorful stalks and aromatic leaves. While it requires a bit more attention than other vegetables, the satisfaction of harvesting your own tender celery is well worth the effort. Your soil, climate, and growing methods will influence your success. Use this guide as a flexible foundation, and adjust as needed to find what works best in your garden.
Choosing the Right Celery Variety
Celery comes in several varieties, each with unique growing habits and flavors.
Popular Varieties:
- Utah 52-70: A classic, tall, and crisp variety commonly found in grocery stores.
- Golden Self-Blanching: A tender, pale variety that doesn’t require as much effort to blanch.
- Redventure: A red-stalked variety with a slightly sweeter flavor and beautiful color.
- Chinese Celery: Smaller, more aromatic stalks often used in Asian cuisine.
Tip: Try different varieties to discover which ones thrive in your garden and suit your taste preferences.
Preparing the Soil
Celery thrives in nutrient-rich, moisture-retentive soil with good drainage.
Basic Soil Guidelines:
- Add compost or aged manure to enrich the soil.
- Aim for a slightly acidic to neutral pH (6.0 to 7.0).
- Ensure consistent moisture levels by adding organic matter like peat moss or well-rotted compost.
Experiment: Try growing celery in raised beds or trenches to better control soil moisture and temperature.
Planting Your Celery
- Starting from Seeds:
- Celery seeds are tiny and slow to germinate. Start seeds indoors 10 to 12 weeks before the last frost. Keep them in a warm, bright spot (around 21C or 70F) and cover lightly with soil.
- Transplanting:
- Transplant seedlings outdoors when they are 10 to 15 cm (4 to 6 inches) tall, and soil temperatures are consistently above 10C (50F).
- Spacing and Depth:
- Plant seedlings 20 to 25 cm (8 to 10 inches) apart in rows spaced 30 to 45 cm (12 to 18 inches) apart.
- Sunlight Needs:
- Celery needs full sun–at least 6 to 8 hours per day–but will tolerate partial shade in hotter climates.

Caring for Your Celery
- Watering: Celery needs consistent moisture. Keep the soil evenly moist but not waterlogged, providing about 2.5 to 5 cm (1 to 2 inches) of water per week.
- Mulching: Apply mulch around the base of the plants to retain moisture, regulate soil temperature, and suppress weeds.
- Fertilizing: Feed with a balanced fertilizer every 2 to 3 weeks to support steady growth.
Observation Tip: If your celery develops tough, bitter stalks, it could be due to inconsistent watering or nutrient deficiencies. Keep soil moisture and feeding consistent.
Blanching Your Celery
Blanching celery helps produce tender, pale stalks with a milder flavor. This process involves covering the stalks to protect them from sunlight.
How to Blanch Celery:
- Trenching Method: As the plants grow, mound soil around the base of the stalks, leaving the tops exposed.
- Covering Method: Use cardboard, newspaper, or boards to cover the stalks about 2 to 3 weeks before harvesting.
Try it and see: Some gardeners prefer the stronger flavor of unblanched celery, while others enjoy the milder taste of blanched stalks.
Harvesting Your Celery
Celery is typically ready to harvest 85 to 120 days after planting, depending on the variety.
How to Harvest:
- Harvest when stalks are firm and reach about 20 to 30 cm (8 to 12 inches) tall.
- Cut the entire plant at the base or harvest individual stalks as needed.
Try it and see: Harvesting individual stalks allows the plant to continue producing, while harvesting the whole plant gives you a larger yield at once.
Storing Celery
Proper storage helps keep celery crisp and fresh.
How to Store Celery:
- Short-Term Storage: Wrap celery in aluminum foil or store in a plastic bag in the refrigerator crisper drawer for up to 2 weeks.
- Freezing: Blanch celery stalks for 3 minutes, cool quickly in ice water, and freeze in airtight containers for use in soups and stews.
Tip: To keep celery crisp, avoid storing it in sealed plastic bags, which can trap moisture and cause wilting.
Common Celery Growing Problems
- Bolting (Premature Flowering):
- Caused by temperature fluctuations or planting too early. Protect young plants from cold snaps and plant at the right time.
- Pithy or Tough Stalks:
- Due to inconsistent watering or nutrient deficiencies. Maintain steady moisture and feed regularly.
- Pests and Diseases:
- Watch for aphids, slugs, and celery leaf blight. Use row covers, hand-pick pests, and practice crop rotation to prevent issues.

Final Thoughts: Your Garden, Your Celery
While celery can be a bit more demanding than other vegetables, the reward of fresh, homegrown stalks is well worth the effort. These guidelines provide a solid foundation, but the best results come from observing your plants and adjusting your care based on your garden’s unique conditions.
Happy gardening, and enjoy your crisp, flavorful celery!
