Why Grow Celeriac, Anyway?
I still remember the first time I discovered celeriac at a bustling French market stall. It sat hunched and gnarly, like the grizzled veteran of the vegetable world, daring me to take it home.
Ugly? Maybe—but beneath that tough exterior hides a tender, nutty flavor that's spectacular roasted or mashed, and a delightfully earthy aroma you can't easily replicate.
Picking the Perfect Spot
Celeriac adores cool temperatures and steady moisture, preferring the sweet spot of around 60–70°F (16–21°C). Give it a semi-sunny patch—about 6 hours of direct sunlight daily—to thrive.
I once mistakenly planted them under too much shade. Result? Knobby disappointments, even grumpier than usual.
Starting from Seed
Start your celeriac seeds indoors about 10–12 weeks before your region's final frost date. As an undeniably slow germinator, patience is a virtue here.
- Sow seeds barely beneath the soil surface.
- Keep consistently damp at temperatures around 70°F (21°C).
- Seedlings should emerge in 2–3 weeks; thin them when they're robust enough to handle.
Transplanting with Care
Celeriac seedlings graduate into the garden bed after frost danger has passed and nights stay consistently above 45°F (7°C). Space them generously about 8–12 inches (20–30 cm) apart, giving their bulbous roots ample elbow room.
"Crowding celeriac is a root cause (pun very much intended) of failed crops."
Spoiling Celeriac (In a Good Way)
Soil Conditions Matter
I pamper mine with compost-rich, loose loamy soil—a cozy root bed free of weed competition. Avoid heavy clay and rocky soils; bulbs hate obstacles and will sulk instead of bulk.
Regular Drinkers
Celeriacs are thirsty little creatures, needing about an inch (2.5 cm) of water each week. Drip irrigation or gentle watering is ideal; shocking their delicate roots triggers unwanted tantrums.
Feed Them Appropriately
A gentle liquid organic fertilizer every few weeks keeps bulbs swelling happily. Celeriac appreciates periodic nitrogen boosts but don't overdo it—too much nitrogen encourages leafy tops at the expense of bulb growth.
Sidestepping Common Troubles
No one escapes the occasional gardening trials, sadly. Celeriac faces common foes navigating diseases like leaf blight and pests such as celery fly larvae.
- Keep plants evenly watered and well-spaced for airflow.
- Regular inspections allow prompt detection before issues escalate.
When to Harvest Those Gnarly Beauties
Patience rewards richly: celeriac matures around 110–120 days after transplanting. Lift bulbs once they've reached baseball-to-softball size, approximately 3–5 inches (7–13 cm) in diameter.
I often leave mine in the ground into early winter, pulling bulbs regularly as needed for warming stews and soups.
Storing and Savoring
After gently brushing away soil, remove foliage and store your celeriac bulbs in sand-filled boxes in a cellar or refrigerator around 34–40°F (1–4°C). They'll stay fresh and firm for months, ready to enrich your culinary pursuits.
Celeriac gratin, remoulade, creamy soups, oven-roasted wedges—the culinary possibilities are mouth-wateringly boundless.

Frequently Asked Questions about Growing Celeriac
What type of soil suits celeriac best?
Celeriac performs best in rich, moisture-retentive soil enhanced with plenty of organic compost. The ideal soil pH ranges from 6.0 to 7.0, providing optimal conditions for steady root development.
How much sunlight does celeriac require?
For flourishing growth, celeriac requires full sun, approximately six to eight hours of direct sunlight daily. While it can tolerate partial shade, full sunlight encourages healthier, more evenly formed bulbs.
When should I plant celeriac seeds?
Start seeds indoors about 8–10 weeks before the last expected frost date in your area. Ideally, seedlings grow best at temperatures around 65–70°F (18–21°C). Transplant seedlings outdoors after frost danger has subsided, aiming for daytime temperatures consistently above 45°F (7°C).
How far apart should celeriac plants be spaced?
To allow ample room for root development, space your celeriac transplants 12–14 inches (30–35 cm) apart, with rows spaced roughly 18 inches (45 cm) apart.
What watering routine supports healthy celeriac?
Maintain consistently moist soil throughout the growing period by supplying about 1–1½ inches (2.5–4 cm) of water weekly. Avoid excessive fluctuations between dry and wet conditions, as uneven moisture increases the risk of splitting roots and growth irregularities.
When is celeriac ready for harvest?
Celeriac typically reaches maturity in around 100–120 days after transplanting. Harvest roots when they measure about 3–4 inches (8–10 cm) in diameter. Harvesting can continue as needed through autumn, making sure to collect the roots before first hard frost arrives.
What common pests and diseases affect celeriac?
Common pests include carrot rust flies and celery leaf miners. Practice crop rotation, maintain garden sanitation, and consider protective row covers as preventive strategies. Watch for fungal diseases like leaf spot and powdery mildew by providing adequate airflow and avoiding overhead watering.
How should harvested celeriac be stored?
Store harvested celeriac roots in a cool, humid location at around 32–40°F (0–4°C). Under these conditions, celeriac will remain fresh for several months. Before storage, carefully brush off excess soil without damaging the skin, but avoid washing roots until immediately prior to use.
Growing celeriac rewards patience and attention with a root vegetable of singular character. Choose a sunny, fertile spot, sow seeds early indoors, and transplant gently after frost. Give ample water, steady compost, and protect from weeds—this humble care brings a harvest worth savoring. Come autumn, your efforts bloom into earthy, flavorful bulbs ready to enrich your kitchen. To garden well is to grow well; celeriac proves it richly.
