Celeriac in the Cool-Season Garden: Succession Planting and Crop Planning

ByStephen Albert

Sharing is caring!

Celeriac is a slow-growing, cool-season crop that benefits from careful planning. Over decades of gardening in Sonoma Valley, I’ve learned that succession planting and thoughtful crop scheduling ensure a continuous harvest while maximizing garden space. By staggering planting dates and coordinating with other cool-season vegetables, you can enjoy celeriac throughout fall and early winter.

Succession Planting

  • Early Planting: Start seeds indoors 10–12 weeks before the last frost to transplant young seedlings in early spring.
  • Late Planting: For a fall harvest, sow seeds mid-summer to transplant in late summer or early fall.
  • Staggered Planting: I plant small groups every 2–3 weeks to avoid having all roots ready at once.

Crop Planning Tips

  • Soil Prep: Prepare fertile, loose, well-drained beds for each succession planting.
  • Companion Crops: Rotate with legumes, brassicas, and leafy greens to reduce pests and improve soil health.
  • Space Management: Use raised beds or containers to maximize growing area and accommodate multiple planting dates.

Harvest Timing

Succession planting allows continuous harvest from late summer into winter. Roots mature 90–120 days after transplanting, so planning ahead ensures you always have flavorful celeriac available.

Tips From Experience

  • Keep detailed planting notes to optimize timing each season.
  • Adjust watering and fertilization for seedlings versus established plants.
  • Protect fall plantings from early frost with row covers when needed.

Bottom Line

By using succession planting and careful crop planning, you can enjoy a steady supply of large, flavorful celeriac throughout the cool season.
