In this post, we’ll walk through how to plant celery root in soil step by step, plus the best conditions for getting celery root to plant successfully in your garden.
Let’s dig in.
How to Plant Celery Root in Soil
Planting celery root in soil starts with understanding what this veggie actually wants from you.
Celery root plants in soil best when the ground is loose, rich, and consistently moist.
Here’s how to get celery root planted in soil the right way:
1. Start Seeds Indoors Before Planting Celery Root in Soil
Celery root takes a long time to mature, usually around 100 to 120 days.
That means you’ll want to plant celery root in soil only after giving the seeds a head start indoors.
Sow celery root seeds about 10 to 12 weeks before your last frost date.
Press the tiny seeds gently into the surface of a seed-starting mix and keep them moist.
Celery root seeds need light to germinate, so don’t bury them too deep when you plant them.
Once seedlings have a few true leaves, they’re ready for the next stage of how to plant celery root in soil.
2. Harden Off Before You Plant Celery Root in Soil Outdoors
Before you plant celery root in soil outside, you have to harden off your transplants.
Set them outside for a few hours each day, gradually increasing their time in the sun and wind over a week or two.
This helps celery root plants adjust before you plant them in soil permanently.
Skipping this step is a common reason celery root planted in soil struggles to survive the transition.
3. Pick the Right Spot to Plant Celery Root in Soil
Celery root plants in soil need full sun, so choose a spot that gets at least six hours of direct light.
The soil itself should be loose, fertile, and well-draining.
Work in plenty of compost before you plant celery root in soil so it has nutrients to feed on all season.
Aim for a soil pH between 6.0 and 7.0 when you plant celery root in soil for the best results.
4. Space Transplants Correctly When You Plant Celery Root in Soil
When you plant celery root in soil, give each plant about 8 to 12 inches of space.
Rows should sit roughly 18 to 24 inches apart.
Set each transplant so the crown sits right at soil level when you plant celery root in soil.
Burying the crown too deep can cause rot, so take your time with this step.
Why You Should Plant Celery Root in Soil in Cool Weather
Timing matters more than almost anything else when you plant celery root in soil.
Celery root plants in soil thrive when temperatures stay between 60°F and 70°F.
If you plant celery root in soil during hot weather, the bulbs turn tough and woody.
That’s why planting celery root in soil works best in early spring for a summer harvest or late summer for a fall harvest.
1. Spring Planting for Celery Root in Soil
For a spring crop, plant celery root in soil about two weeks before your last frost date.
The cool weather helps celery root establish itself before the heat arrives.
2. Fall Planting for Celery Root in Soil
For a fall harvest, plant celery root in soil in late summer.
Those plants finish up right as the weather cools, which celery root loves.
3. Avoid Mid-Summer Planting
Never plant celery root in soil at the peak of summer.
Heat stresses the plants and stops the bulbs from forming properly.
Caring for Celery Root After You Plant It in Soil
Once you plant celery root in soil, the work isn’t over.
Celery root planted in soil needs steady moisture, so water deeply whenever the top inch of soil dries out.
Mulch around each plant to lock in moisture and keep weeds down.
Feed your celery root every few weeks with a balanced fertilizer for steady growth.
You can also snip off outer leaves as the bulbs swell, but leave the center alone.
So, How Do You Plant Celery Root in Soil?
You plant celery root in soil by starting seeds indoors, hardening off the transplants, choosing a sunny spot with rich soil, and spacing them properly.
Celery root plants in soil best during cool weather, so timing your planting around spring or fall gives you the biggest, healthiest bulbs.
Once you plant celery root in soil and keep it watered and mulched, you’ll be harvesting those earthy, nutty bulbs before you know it.
