Carrots are one of the most rewarding vegetables to grow — they don’t take up much space, they come in a rainbow of colors beyond the usual orange, and they’re surprisingly easy once you know a few tricks. Whether you have a large garden bed or just a deep container, the right planting method, soil preparation, and timing can set you up for a harvest that lasts for months. In this guide, we’ll walk you through everything from choosing the best time to plant to caring for your crop and harvesting at the perfect moment.
How to Plant Carrots from Seed
Sun: full to part sun • Soil: loose, well-drained, pH 6.0–6.8 • Depth: ¼ inch (0.5–1 cm) • Spacing: thin to 2–3 in (5–7.5 cm) • Germination: 7–21 days
Step-by-step: How to plant carrot seed
- Pick the right spot. Carrots love sun and loose soil. Avoid heavy clay or rocky patches — if that’s your only option, use a raised bed or a deep container.
- Prepare the soil. Remove stones and large clumps. Rake the surface to a fine tilth so tiny seeds can push through easily. Work in compost well before planting, not fresh manure.
- Make shallow drills. Use a hoe or trowel to create a trench about
¼ inch (0.5–1 cm)deep. Space rows roughly12–18 inches (30–45 cm)apart if planting multiple rows. - Sow the seeds thinly. Carrot seeds are tiny. Try mixing them with a little clean sand to help spread them evenly, or use pelletized seed. Aim for about
1–2 inches (2.5–5 cm)between seeds. - Cover and water gently. Lightly cover seeds with fine soil or sifted compost. Water with a can fitted with a rose or a gentle hose setting so you don’t wash the seeds away.
- Keep the bed moist. Germination takes
7–21 days. Keep the soil surface consistently damp — not soaked. In hot or windy weather, cover with burlap or horticultural fleece until seedlings appear. - Thin carefully. When seedlings reach about
2 inches (5 cm)tall, thin them so plants are about2–3 inches (5–7.5 cm)apart. Thin on a cool, still day to avoid attracting carrot fly with crushed foliage. - Care while growing. Keep weeds under control (hand-weed close to plants). Water during dry spells — steady moisture helps prevent splitting. Avoid excess nitrogen.
- Protect from pests. Use fine mesh or floating row cover if carrot fly or flea beetles are a problem. Companion rows of onions or garlic can help mask the scent, and tidy garden hygiene reduces pests like carrot weevil.
Tips & troubleshooting
- Forked roots: Often caused by stones or fresh manure — screen soil and avoid high-nitrogen feed.
- No germination: Keep the seedbed moist; cooler soils (45–70°F / 7–21°C) germinate best.
- Split carrots: Caused by fluctuations in moisture — water regularly and evenly.
Baby carrots can be harvested in 4–6 weeks. Most varieties mature in 70–90 days depending on type and conditions.

How to Care for Your Carrots
Carrots are pretty low-maintenance once they’re up and growing, but they do need a little attention early on. Keep the soil consistently moist, especially while the seeds are germinating — which can take a couple of weeks. Once seedlings are around 2 inches tall, thin them to about 3 inches apart so they’ve got space to bulk up. Weeds are your main enemy here, so pull them out regularly, but be gentle to avoid disturbing the roots.

The Best Way to Plant Carrots?
Carrots are at their best when you sow them directly into the ground rather than starting them in trays. They hate having their roots disturbed, so avoid transplanting if you can. Choose a sunny spot with light, crumbly soil that’s free of stones and lumps — this helps the roots grow straight. Make a shallow drill about a quarter-inch deep, sow the seeds thinly, and cover them with a fine layer of soil. Keep the rows spaced 12 to 18 inches apart.
The Best Time to Plant Carrots
Carrots are cool-season lovers. They grow best when the weather is mild, so aim to plant them when
temperatures sit between 55°F and 75°F. Too hot and they risk bolting; too cold and germination slows.
Which is the Best Month to Plant Carrots?
In most places, late March to early June is prime carrot-planting season for a summer harvest. For an autumn crop, plant again in late summer — about 10 to 12 weeks before your first expected frost. If you live somewhere mild, you can stretch that window even further.
Are Carrots Easy to Grow in a Garden?
They’re one of the easier veg to grow — as long as you get the soil right. Carrots don’t need a ton of fussing over, just the right conditions to start with. Once they’re established, they practically take care of themselves.
What’s the Secret to Growing Carrots?
Good soil preparation is the big one. Loose, well-drained soil with no stones is the difference between a perfect, straight carrot and a twisted, forked one. Sowing thinly so you don’t need to do much thinning later will also save you from attracting carrot fly, which loves the scent of crushed foliage.
How Long Do Carrots Take to Grow?
It depends on the variety, but most carrots are ready in 70 to 80 days. Smaller, early types can be ready in as little as 50 days, while big storage varieties can take closer to 90. Baby carrots can be pulled even sooner if you like them tender and sweet.
The Soil to Plant Carrots
Carrots like light, sandy loam with a pH between 6.0 and 6.8. Heavy clay tends to produce wonky roots, so if that’s your soil type, either improve it with compost well in advance or grow short, round carrot varieties instead.
Do Carrots Like Wet or Dry Soil?
They like it just right — consistently moist, but never soggy. Too much water can rot the roots, while letting the soil dry out completely can make them tough or cause them to split. Aim for steady, even moisture throughout their growth.
Harvesting Carrots at the Right Time
Harvest when the tops of the roots look plump and the shoulders are about three-quarters of an inch across. Loosen the soil with a fork before pulling to avoid snapping them in half. If you can wait until after a light frost, even better — the cold turns their starches into sugars, making them noticeably sweeter.
FAQ
How deep should I plant carrot seeds?
Plant seeds about 1/4 inch deep and cover lightly with fine soil or sifted compost. Keep the seedbed moist until seedlings appear.
When is the best time to sow carrots outdoors?
Sow in early spring 2–4 weeks before your last frost, or in late summer for a fall crop. Carrots prefer cool soil for germination.
How often should I water carrot seedlings?
Water to keep soil consistently moist—about an inch per week is a good guideline. Avoid long dry spells which make roots woody.
What spacing do carrots need?
Thin seedlings to 2–3 inches apart. Space rows 12–18 inches apart for comfortable access and growth.
