How Many Carrot Seeds Per Hole

Carrots are a popular and versatile root vegetable, prized for their sweet flavor and nutritional benefits, such as being packed with beta-carotene. One of the most critical factors in successfully growing carrots is how many seeds per hole. Unlike seeds of other plants, carrot seeds are tiny, and it’s challenging to count them, so it’s essential to use the correct technique to ensure proper spacing of your carrot seed to grow carrots with healthy roots.

The number of seeds in each hole will depend on several factors, including the size of all the seeds, the desired final yield, and the specific carrot variety. When planting carrot seeds, it’s vital to ensure the soil is loose and moist, as this will help the seeds germinate and promote healthy root growth.

Compacted soil can lead to poor germination rates and stunted growth, so preparing the soil carefully before planting is crucial. Besides proper soil preparation, choosing the suitable carrot variety for your growing conditions and the preferred flavor is essential. Some varieties are better suited to hot weather, while others thrive in cooler climates.

Recommended Carrot Seed Starting Methods

Carrots can be started indoors or outdoors, depending on the climate and growing season.

For spring planting, start seeds indoors in late winter. For direct sowing in the garden, wait until the soil has warmed up in the spring.

Plant carrot seeds in loose, moist soil to ensure healthy root development.

How Long From Seed To Harvest?

Carrots take about 70-80 days from seed to harvest. However, this can vary depending on the variety, growing conditions, and planting method.

  • To avoid a bitter flavor, avoid high-nitrogen fertilizer. Plant only one seed per hole if using pelleted seeds, which are coated in clay to make them easier to handle.
  • Plant carrots with well-draining soil in raised beds or containers to ensure successful growth.
  • Carrots thrive in loose soil with plenty of organic material, like compost.
  • When watering, use a gentle stream from a garden hose to avoid disturbing the seeds or young plants.

Planting Carrot Seeds

Carrot seeds are tiny, and it’s challenging to determine how many seeds to plant per hole.

  • The general rule of thumb is to plant two to three carrot seeds in each hole.
  • When planting carrot seeds, it is essential to keep the soil moist.
  • If the soil dries out, the seeds may not germinate correctly. You can cover the seeds with a thin layer of soil and water gently with a hose to keep the soil moist.
  • Avoiding high-nitrogen fertilizers is crucial as too much nitrogen can cause the carrots to grow many roots, which can cause a bitter taste.

When To Plant Carrot Seeds


Carrots are a cool-season crop and prefer temperatures between 60-70°F (15-21°C) for optimal growth. Planting carrot seeds in early spring, as soon as the soil can be worked, is ideal. However, if you live in a warmer climate, you can plant carrot seeds in the fall for a winter harvest. If the temperature is too high, the seeds may not germinate, or the seedlings may not grow well.

Direct Sowing

Carrots grow best when they are directly sown into loose, well-draining soil. Avoid planting in compacted soil, leading to stunted growth and misshapen roots. To plant carrot seeds, create shallow holes a few inches apart, and place two to three carrot seeds in each hole. Cover each of the seeds with soil and water gently.

Seed Spacing

It’s important to space carrot seeds properly to avoid overcrowding. However, too few seeds per hole can lead to uneven growth and wasted space in the carrot bed. A general rule of thumb is to plant 2-3 seeds per hole and thin carrots from the strongest seedling after germination.

Seed Depth

Carrot seeds are tiny, and it’s important not to plant them too deep. Plant your carrot seeds about 1/4-1/2 inch deep.


Adding fertilizer doesn’t mean larger carrots. Carrots don’t require a lot of fertilizer, but they need some organic matter to thrive. Before planting, work in a thin layer of organic fertilizer or compost to provide the necessary nutrients to the soil or potting mix if growing carrots in containers or raised beds.

How To Plant Carrot Seeds Step-By-Step

Carrots are root vegetables to be grown successfully in loosely packed soil free of rocks and other debris. They thrive in soil that is kept moist but not too wet, and they require plenty of organic matter to promote healthy roots.

Here are the steps to planting carrot seeds:

  1. Prepare the soil: Before planting, ensure the soil is tilled and loosened to a depth of at least 12 inches. The carrots may have trouble growing properly if the soil is too compacted.
  2. Sow the seeds: Make shallow trenches or holes in the soil, and drop the seeds in. Or, sprinkle them over the soil, then gently work them down to about 1/4″ deep.
  3. Thin the carrots: Once the seedlings have emerged, thin them to one seed per 1-2 inches. If there are too many seeds per hole, the carrots may form many roots and be too small to harvest.
  4. Water the seeds: After planting, water the seeds gently with a garden hose or watering can. Be careful not to overwater, which can cause the seeds to rot.
  5. Watch for pests: Carrot rust fly and leaf blight can be common problems for carrot plants. To avoid these issues, consider planting carrots in raised beds and using organic fertilizer to promote healthy growth.
  6. Harvest the carrots: The growing season can range from early spring to early winter depending on the carrot variety. When the carrot roots have reached their preferred flavor and size, gently pull them from the soil at the base of the plant.

Overall, growing carrots from seed can be a rewarding experience if done correctly.

Following these steps and avoiding common mistakes, you can grow healthy, fresh carrots in your backyard.

What Do Carrot Seedlings Look Like?

Carrot seeds are tiny, and it’s challenging to see them when planting. When they first sprout, the seedlings have two long, narrow leaves called “seed leaves.”

After that, the rest of the leaves that form are referred to as “true leaves,” and they look just like tiny baby carrot leaves.

Thinning Seedlings

It is vital to thin carrot seedlings to promote healthy root development. If there are too many seeds per hole, the carrots compete for nutrients and may form multiple roots, resulting in smaller, misshapen carrots. It is recommended to sow 2-3 carrot seeds per hole. If the seeds are 1-2 years old, sprinkle 30-40 seeds per foot (30 cm) and thin them out later.

When thinning, leave the strongest seedling in the soil and pull out the rest, or snip the weaker ones at the soil line. Experts suggest digging shallow holes a few inches apart and putting two to three carrot seeds per hole.

Cover each seed with soil and wait for approximately a week. You should see seedlings appear in around 5 to 7 days. If the seedlings turn green, it may indicate overcrowding or a lack of nutrients. To avoid this, plant one or other seedlings per hole and thin as necessary.

Carrots grow best in aerated soil, and they thrive in raised beds. It is also essential to keep the soil moist but not waterlogged. Growing carrots from seed can be a rewarding experience, but it requires patience and proper care to grow carrots. Following these tips and techniques, you can grow a healthy and abundant carrot crop. (Read Is Dill Seed The Same As Dill Weed)

Carrot Pests

Carrot rust fly is a common pest to damage your carrot crop. Cover your carrot bed with a floating row cover to prevent this pest or use a physical barrier like a board or paper collar. Also, rotate your carrot bed yearly to reduce the risk of pests and diseases.

Note: When thinning, remove the thinned seedlings as carrot fly follow the scent of crushed carrot tops. Thrips can also be an issue if you are growing onions, as they can pass to your carrots.

Common Carrot Diseases

Leaf blight is a common disease that affects carrot plants. To prevent this disease, avoid overhead watering and keep the foliage dry. Also, remove any infected plants and avoid planting carrots in the same spot for three years.

Carrot Care Tips

Keep the soil moist but not waterlogged to ensure healthy carrot root development. Thin carrots 2-3 inches apart to avoid overcrowding and promote root growth. Use organic fertilizer to provide nutrients for the growing carrots. Avoid high-nitrogen fertilizers that cause the carrots to form multiple roots and have an unpleasant taste.

Planting Carrot Seedlings

Plant your carrot seedlings in early spring or winter, depending on your growing season and preferred flavor. When planting, gently pack the soil around the seedling and water it with a garden hose. Plant one carrot seedling per hole and space the holes 2-3 inches apart.

Direct Sowing Carrot Seeds

If you are direct sowing carrot seeds, plant them in looser soil that has been amended with organic material. Sow the seeds 1/4 inch deep and 1-2 inches apart. Water the seeds with a gentle spray to avoid washing them away. Thin the seedlings 2-3 inches apart once they have their first true leaves.
