Growing celeriac, also known as celery root, can be a rewarding addition to your vegetable garden. With its unique flavour and versatility in the kitchen, it's a fantastic crop to cultivate. We're the Hedge Cutting Staffordshire team, a professional gardener based in Staffordshire, and I'm here to guide you through the process of growing celeriac in the UK.
Quick Answer
To grow celeriac in the UK, start seeds indoors in February, transplant seedlings outdoors in May, and harvest from October to November. Keep soil moist and provide consistent care for a healthy crop.
Understanding Celeriac
Celeriac, a variety of celery grown for its large root, thrives in the cool, damp conditions typical of the UK. It's particularly well-suited to our Midlands climate, requiring a long growing season of about 7 to 8 months.
Preparing the Soil
Before planting, it's crucial to prepare your soil. Celeriac prefers a rich, well-drained soil with plenty of organic matter. Here in Staffordshire, our clay soils can be improved by adding well-rotted manure or compost.
- Ensure soil is free-draining to prevent waterlogging.
- Incorporate organic matter to improve fertility.
- Test soil pH; aim for a neutral range of 6.5 to 7.5.
Starting Seeds Indoors
Begin by sowing seeds indoors in February. Use seed trays filled with a quality seed compost. Celeriac seeds are tiny, so sow them thinly and cover lightly with compost.
Timing Guide
| Task | Month | Details |
|---|---|---|
| Sow seeds indoors | February | Use seed trays, keep warm and well-lit |
| Transplant outdoors | May | After last frost, harden off seedlings |
| Harvest | October - November | Lift when roots reach tennis ball size |
Transplanting and Care
Harden off seedlings gradually by placing them outdoors for increasing periods over a week. Transplant them to the garden in May, spacing about 30cm apart each way.
Regular watering is essential, especially during dry spells. Mulch around plants to retain moisture and suppress weeds.
Harvesting Celeriac
From October to November, when roots are roughly the size of a tennis ball, it's time to harvest. Use a fork to lift them gently to avoid damage.
