Learn how to grow carrots from carrot tops for greens or seeds with tips from Ashley Scott, a 10-year gardening pro. Perfect for USA gardens!
Hey there, veggie growers! I’m Ashley Scott, a gardening enthusiast with 10 years of experience cultivating vegetables in my USA backyard. If you’ve ever wondered how to grow carrots from carrot tops, you’re in for a fun experiment! While you can’t grow a full carrot directly from a top (since carrots don’t regenerate their taproots this way), you can use carrot tops to sprout greenery, collect seeds, or even propagate roots for a second crop under the right conditions. This method is a great way to reduce kitchen waste and engage kids, much like my succulent propagation projects. Below, I’ll guide you through how to regrow carrot tops, potentially grow new carrots from seeds or root pieces, and share care tips, my personal stories, and ties to projects like DIY compost bins at USA Garden Hub. Let’s get those carrot tops sprouting!
Can You Grow Carrots from Carrot Tops?
Technically, carrot tops (the leafy greens) won’t grow a new carrot taproot directly, as carrots are biennials that need two years to complete their life cycle: growing a root in year one and producing flowers and seeds in year two. However, you can:
- Regrow Greenery: Place carrot tops in water or soil to sprout lush greens, perfect for garnishes or pesto.
- Collect Seeds: Let sprouted tops flower (second year) to harvest seeds for planting new carrots.
- Propagate Roots (Limited): With a piece of the carrot root attached, you might encourage new root growth in soil, though results vary.
This guide focuses on regrowing tops for greens or seeds, with tips for attempting root propagation, tailored for USA gardens in USDA Zones 3 to 10.
How to Grow Carrot Tops: Step-by-Step
Here’s how to turn those kitchen scraps into vibrant greens, with a nod to seed collection or root propagation.
1. Prepare Carrot Tops
- What You Need: Fresh carrots with green tops (organic or homegrown work best, avoid pesticide-treated store carrots), a knife, a shallow dish or pot, water, and well-drained soil or potting mix.
- How to Do It: Cut the top 1 inch of the carrot, keeping some root flesh and the green stubs. Trim off excess greens, leaving about ¼ inch of stems.
- My Tip: I used farmers’ market carrots, as store-bought ones sometimes sprout slowly due to treatments.
2. Sprout in Water (For Greens or Seeds)
- Setup: Place the carrot top, cut side down, in a shallow dish with ½ inch of water. Set in a sunny spot (6 hours of light daily, like full sun).
- Care: Change water every 1 to 2 days to prevent mold. Expect green shoots in 3 to 7 days, growing 4 to 6 inches in 2 to 3 weeks.
- Outcome: Lush greens for salads or pesto. If left for a second season (in soil), tops may flower and produce seeds.
- My Story: My kids loved watching carrot tops sprout on our kitchen windowsill, a fun science project!
3. Transplant to Soil (For Greens, Seeds, or Root Attempts)
- Setup: After sprouts appear (1 to 2 inches), move to a pot or garden bed with loamy soil (pH 6.0 to 6.8). Bury the cut side ½ inch deep.
- Care: Water to keep soil moist but not soggy (1 inch weekly). Place in full sun or bright indoor light. Add compost from my DIY compost bin for nutrients.
- Outcome:
- Greens: Harvest at 4 to 6 inches for culinary use.
- Seeds: In year two (Zones 3 to 9), plants may bolt, producing umbel flowers for seed collection. Store seeds dry for spring planting.
- Roots: With a larger root piece (1 to 2 inches), some new taproot growth may occur, though it’s often small or misshapen.
- My Tip: I transplanted mine to a pot, and the greens were perfect for soups, but my root attempts were tiny, not like store carrots.
4. Growing New Carrots from Seeds
- Planting Seeds: Sow collected seeds in spring, ¼ inch deep, 2 inches apart in loose soil. Thin seedlings to 3 inches apart.
- Care: Water evenly, keep soil weed-free. Harvest carrots at 60 to 80 days (3 to 4 inches long).
- My Story: I planted seeds from a second-year carrot top, and my ‘Nantes’ carrots were sweet and crunchy!
Care Tips for Carrot Tops and New Plants
- Light: Full sun (6 to 8 hours) for robust greens or seed production. Indoor growers, use a grow light.
- Water: Keep soil consistently moist for tops (1 inch weekly). Avoid overwatering to prevent root rot.
- Soil: Use sandy or loamy soil, enriched with compost from my DIY compost bin. Avoid heavy clay to prevent stunted roots.
- Temperature: Carrots grow best at 60 to 75°F, hardy in Zones 3 to 10. Protect from frost with mulch.
- Fertilizer: Apply a low-nitrogen fertilizer (5-10-10) monthly for greens or new plants. Too much nitrogen leads to leafy growth, not roots.
- Pests: Watch for aphids on greens, use soapy water or plant with marigolds for protection, like my neem oil guide.
Common Problems and Fixes
- Mold in Water: Change water daily, ensure good air circulation. I had mold once from neglecting water changes.
- Leggy Greens: Too little light, move to a sunnier spot or use a grow light.
- No Root Growth: Carrot tops rarely form large roots, focus on greens or seeds for better results.
- Pests: Carrot flies can affect new plants, cover with row covers.
Why Grow Carrot Tops?
Regrowing carrot tops is a sustainable, budget-friendly way to enjoy fresh greens, collect seeds, or experiment with roots. It’s perfect for kids, urban gardeners, or anyone wanting to reduce waste. Pair with pollinator-friendly plants to boost garden health. The greens add a parsley-like flavor to dishes, and the process is as fun as growing spooky plants or Nerine flowers.
Wrapping Up
Growing carrots from carrot tops is a delightful project, yielding tasty greens, seeds for future crops, or small roots with some luck. My kitchen experiments turned into a thriving pot of carrot greens, and my seed-grown carrots were a hit. Whether you’re in a rural yard or a city apartment, this method is easy and rewarding.
