rapaceum Prinz (Celeriac Prinz) Plant Care Tips

When it comes to growing vegetables in your garden, celeriac is often overlooked.

However, this versatile and delicious root vegetable deserves a place in every garden.

Celeriac, scientifically known as Apium graveolens var.

rapaceum Prinz, is a variety of celery that is grown for its flavorful and aromatic root rather than its stalks or leaves.

Choosing the Right Location

Celeriac plants thrive in cool climates and require full sun to grow properly.

Choose a location in your garden that receives at least 6-8 hours of direct sunlight each day.

Additionally, celeriac prefers well-draining soil with plenty of organic matter.

Sowing Seeds

Celcriac seeds can be sown directly into the ground or started indoors before transplanting seedlings into the garden.

If you choose to start seeds indoors, sow them about 10 weeks before the last expected frost date in your area.

  • Fill seed trays or pots with seed starting mix.
  • Sow one or two seeds per cell or pot, about 1/4 inch deep.
  • Mist the soil with water to keep it moist but not soggy.
  • Place trays/pots under grow lights or near a sunny window where they will receive bright light for at least 12-14 hours each day.
  • Seedlings should emerge within 7-14 days.(Tip: For best results soak seeds overnight before sowing)


Maintaining Proper Soil Moisture

Celriac plants prefer consistently moist soil but do not tolerate waterlogged conditions.

Water your plants regularly, especially during dry spells, and mulch around them to help retain soil moisture.

Avoid overhead watering as it can increase the risk of fungal diseases.

Fertilizing Celeriac Plants

Before planting celeriac in your garden, amend the soil with compost or well-rotted manure to provide the plants with essential nutrients.

Once the plants are established, side-dress them with a balanced fertilizer every 4-6 weeks throughout the growing season.

  • Apply a nitrogen-rich fertilizer such as fish emulsion or blood meal when transplanting seedlings into the garden.
  • During mid-season, apply a slow-release fertilizer to ensure continuous nutrient supply.
  • Avoid over-fertilizing as it can lead to lush foliage growth at the expense of root development.(Tip: Check soil pH regularly and aim for a pH level between 6.0-7.0 for optimal growth)

Pest and Disease Control

Celriac is generally resistant to pests and diseases; however, there are still some common issues you should be aware of:


  • Aphids: These small insects can cause damage by sucking sap from plant leaves.

    Use insecticidal soap or neem oil spray to control aphid infestations.

  • Celery Leaf Miner: The larvae of this pest tunnel through celery stems and leaves causing significant damage.

    Regularly inspect your plants and remove any affected foliage promptly.

  • Fungal Diseases: Celeriac is susceptible to fungal infections such as leaf blight and root rot in high humidity conditions.
    • To prevent these diseases, ensure proper air circulation around plants by spacing them appropriately.
    • Avoid overhead watering and water plants at the base to minimize moisture on foliage.
    • If necessary, apply a fungicide according to label instructions.

    Harvesting Celeriac

    Celriac is ready for harvest when the root reaches about 3-4 inches in diameter.

    Carefully dig around the root and lift it out of the ground.

    Remove any soil clumps and trim off the leaves, leaving about an inch of stem attached to the root.

    Store harvested celeriac in a cool, dark place with high humidity.(Tip: Celeriac can be stored for several months if kept properly)
