Carrots. Carrots are one of the most popular vegetables that gardeners plan to grow, but many gardeners are disappointed when they have trouble.
Carrot growing problems are completely normal, and thankfully most of them can be prevented. You can learn how to avoid or fix the most common problems that new carrot growers have in the podcast episode and blog post below.
With a little bit of knowledge, you may just find yourself harvesting more carrots than you’ve ever imagined!

Carrots are a favorite vegetable for many gardeners. Their sweet, crunchy roots add flavor and nutrition to salads, soups, roasts and more. However it can be frustrating when your eagerly awaited carrot harvest turns out to be small and stubby roots instead of the long tapered carrots you were expecting.
Small carrots are often caused by issues with soil conditions, moisture, sunlight or spacing. The good news is that with a few simple fixes, you can get your carrot crop back on track next season. Here are the 7 most common reasons for small carrots and what to do about them:
1. Rocky, Compacted Soil
Carrots need loose, crumbly soil to support their long root growth. Heavy clay or compacted soils make it difficult for the carrots to push through and expand. Rocks and stones also interfere with the carrot’s downward growth, causing stunted roots.
Solution Improve the soil structure by mixing in 2-3 inches of compost before planting. Loosening the soil with a garden fork can also help. For quick drainage and easier growing try raising the carrots in deep containers or raised garden beds filled with loose potting mix.
2. Insufficient Watering
Consistent moisture is critical, especially when seeds are germinating and young carrots are becoming established. Letting the soil dry out causes growth to slow or stunt.
Solution: Water the carrot bed frequently, aiming for 1-2 inches per week. Use a mulch to conserve moisture. Check soil moisture before watering again, and increase frequency during periods of heat or drought.
3. Planting Too Deep
Carrot seeds need to be planted shallow, no more than 1⁄4 inch deep. Planting too deeply can inhibit germination or result in seedlings that fail to push through the excess soil.
Solution: Sow seeds onto the soil surface, then sprinkle on a light layer of fine soil or compost. Gently water to moisten the top layer where seeds are planted.
4. Too Much Nitrogen
An excess of nitrogen fertilizer leads to lush leafy tops but stunted roots on carrots. The energy goes into foliar growth instead of the roots.
Solution: Avoid over-fertilizing with nitrogen. Moderate amounts of balanced organic fertilizer (like 5-5-5) are sufficient. Let compost be your main soil amendment.
5. Crowded Growing Conditions
When seeded too closely, carrot seedlings compete for nutrients and water as they grow. This leads to under-developed roots.
Solution: Thin carrots to 1-2 inches apart when they are 2-3 inches tall. This gives them ample room to size up.
6. Poor Sun Exposure
Carrots need at least 6 hours of direct sunlight per day. With insufficient sunlight, the tops will be small and sparse, and the roots will be stunted.
Solution: Locate your carrot bed in a sunny spot. If shade is unavoidable, try a short variety like ‘Amsterdam Forcing’.
7. Harvesting Too Late
Given enough time, carrots will eventually stop growing and become woody. The sugars convert to starches, creating a bitter taste.
Solution: Pull carrots when they reach the desired size, typically 2-3 months from seeding. Sow a new batch every 2-3 weeks for a continuous harvest.
Tips to Grow Better Carrots
Here are a few more tips to help you grow your best carrots yet:
-
Select fresh seeds of recommended varieties like ‘Danvers’, ‘Scarlet Nantes’ or ‘Cosmic Purple’.
-
Enrich soil with 2-3 inches of aged compost or rotted manure before planting.
-
Consider using row covers at seeding time to retain moisture and prevent insect issues.
-
Keep beds weed-free to reduce competition.
-
After germination, thin carrots to proper spacing for sizeable roots.
-
Water deeply and regularly throughout growth. Up to 1-2 inches per week.
-
Side dress with a balanced organic fertilizer or compost halfway through growth.
-
Harvest carrots at their peak before quality declines.
-
Rotate planting location each year to prevent disease buildup.
With the right growing conditions and care, your carrot crop can transform from small and stubby to long, straight and flavourful. Pay close attention to soil, moisture, sunlight, spacing and fertility for better results next season. It takes some patience and practice, but the sweet carrot harvest is worth it. Let those small carrots be a lesson learned, not a failure. Now you know what to improve for next year’s carrot success!
What’s root branching (hairy roots)?
It’s called root branching or hairy roots when you see a lot of feeder roots coming off of your carrot. It’s really not a huge problem, but it’s a sign of too much nitrogen in your soil.
Carrots don’t need extra nitrogen like a lot of plants. This is why compost is ideal because your carrots can uptake exactly what they need.
Why are the greens and roots so small?
If your soil is loose and full of nutrients, but your carrot greens are still small, what could be wrong? It’s most likely a lack of light. Carrots need full sun or very light shade. And if you planted them somewhere they won’t get this, you might end up with very small leaves and roots.
How to Tell When Carrots Are Finished Growing : The Chef’s Garden
Why are my carrots small?
Here’s the quick answer. Your carrots are small for one or more of the following reasons: You grew your carrots in heavy, compacted soil. Your carrots didn’t get enough water. Your carrots didn’t get enough sunlight. Your carrots received too much nitrogen. Your carrots were overcrowded. You harvested your carrots too soon.
Do carrots have blood thinning properties?
Carrots do not have blood-thinning properties. However, they are a good source of vitamin K, which is important for blood clotting. Some vegetables and herbs that may have a blood thinning effect include garlic, ginger, and turmeric. If you are taking a blood-thinning medication, talk to your doctor before adding these foods to your diet.
Why are my carrots growing too close together?
However, if the seeds have a high germination rate, then you can end up with too many carrots that are too close together. In this case, the carrots will compete with each other for water and nutrients in the soil. The best way to solve this problem is to thin out your carrots.
Why are my carrots growing so tall?
This simply means that the top of your carrots saw sunlight when they were growing. This isn’t a problem or toxic like with potatoes. Just cut it off and go on. You can prevent it by taking a bit of soil and covering them as they grow when you see them poking through. Why are my carrots growing REALLY tall?
