Common Problems Growing Carrots And How To Avoid Them

Carrots are undoubtedly a great addition to many a meal. Whether you’re cooking up a stew, soup, or whipping up a stir fry, carrots can add an extra oomph to your pot. Since you’re on my garden blog, I’d assume (hopefully correctly so,) that you are either interested in growing your own, or are already growing your own produce.

Adding carrots to your garden should be no hassle, and actually an incredibly rewarding experience. Not only do you get the satisfaction of providing fresh, nutritious food for yourself and your family, but you also get to enjoy the delicious flavour of freshly picked carrots.

Bear in mind that growing carrots can be challenging and there are a few common problems that can arise. I won’t go as far as saying that growing carrots is not for the faint of heart. Trust me when I tell you that the process can actually be quite a wonderful experience. Holding your batch of bright orange (or purple) carrots, knowing the many pitfalls that you have successfully avoided,  will no doubt inspire so much confidence in yourself. (You’ll also be tempted to hold it above you head while playing the Lion King theme song in the background. Am I speaking from experience? Maybe…)

I digress. In this blog post, I will explore the most common problems associated with growing carrots and help you by sharing tips on how to avoid them. From proper soil preparation to water management, think of this as a great carrot growing heart to heart from me to you. Thank me later (or better yet, leave me a comment). 

If you’re new to gardening, it’s easy to make mistakes that can set you back. Stick with me and let’s walk through the process of avoiding pitfalls and challenges in growing carrots. 

With the right knowledge and a little bit of effort, you can enjoy a bountiful harvest of carrots.

Why Aren’t My Carrots Sprouting

Growing carrots can be a tricky process, and it’s all too easy to end up with unappetising, miniature carrots. I mean, you’ll still be proud of your produce, but why not go all out and make it the best carrots you’ve ever seen? (Even better than Wholefoods! Haha). Browse below for some causes of common problems and my suggested solutions. 

Deep Planting

As a new gardener it may be tempting to shove your seeds all the way down into the soil. Nope! Doesn’t work when it comes to carrots. One of the most common causes of small carrots is planting the seeds too deeply in the soil.

When sowing carrot seeds, you should only cover them with about 1/4 inch of soil.

There is only so much energy that a seed provides before the plant needs sunlight to thrive. If you bury the seeds too deeply, the young plants may struggle to reach the surface and will fail to develop properly.


The ever enthusiastic voice in the back of your mind will no doubt suggest that you plant as many crops as possible. Tell it to be quiet! Crowding out your carrot seedlings will create less room for the little sprouts and roots. But just think about it like this, if there were 10 sandwiches on a table, would it be better to have 10 of us seated and sharing it or 45?

It is the same with planting. The “resources” (aka nutrients in the soil) are better off being split a few ways rather than shared among a whole forest (you get my point).

Carrots should be planted about 2-3 inches apart, so that the roots have enough room to grow. Crowded carrots will stay small and will be difficult to pull out of the ground.

Soil Quality

Thin of the soil as something of a nappy/diaper. It’s there to facilitate, but it shouldn’t be left to get too wet. (Strange analogy? I know). But jokes aside, soil quality is another important factor when it comes to growing carrots.
Carrots prefer soil that is loose and well-draining, with a neutral pH level.

Poor quality soil may contain too much clay or sand, which can limit carrot growth.

Water and Sunlight

Plants are like mini-humans (or is it the other way around?). My point is, we both need the right amounts (lots of) sunlight and water to thrive. Too little water and sunlight can result in carrots being stunted and small.

To make sure your carrots receive enough water, make sure they’re watered often (daily), especially if you live in a hot/dry place.

Keep the soil moist but not wet to ensure healthy root development. Carrots also need plenty of sunlight; try keeping them positioned near a south-facing window for optimal exposure!

By avoiding these common problems, you can ensure that your carrots reach their full size potential! Bye bye weekly market run! 

Hairy Roots (aka Root Branching)

Why are your carrot roots hairy? Root branching, also known as hairy roots, is a common problem when growing carrots in the garden. Ugh!

Root branching happens when the carrot root splits into multiple strands and can drastically reduce the amount of carrots you get. How can you avoid this problem? Scroll… well, and read (and do as I say. Haha)

How To Prevent Root Branching

Check Nitrogen Levels

Root branching is usually caused by too much nitrogen in the soil or by uneven watering. Sounds a bit scientific right? I mean, it is, but it’s not as complicated as it sounds.

To avoid root branching, you should check your soil for a high nitrogen content. A simple way? Check your fertiliser. When growing carrots (and food in general), natural is always better. Controlled release fertilisers (aka many store-bought fertilisers), have way too much nitrogen for carrot seedlings.

It might sound long, but it actually is better to prep your soil from the previous autumn, using leaves, manure, compost…aka the good stuff. That way the nutrients are broken down over time in the soil and become phosphorus-rich instead of nitrogen-rich.

You should also water your carrots evenly and not let the soil become soggy or dry out completely.

Use Raised Beds

Raised beds basically prevent water from pooling around the roots of your seedlings.

Also, you can ensure that your soil’s nutrients are those which you want (meaning, less nitrogen). For example, if you intend to practice companion planting (check out my handy guide here), you’ll remember to keep those nitrogen producing plants far away.

By elevating the soil, you are providing an environment that is better suited to carrot growth.

Having the carrots in a raised bed or container makes it easier to monitor moisture levels and can help to avoid overwatering or underwatering.

Thin The Plants

You should use thinning scissors to thin your carrot plants during their early growth stage.

Thinned carrot plants will allow for more air circulation, which can help to prevent root branching.

Why Do My Carrots Split, Crack and Fork?


Carrots can split, crack and fork as they grow, leading to an unsightly harvest. However, with the right care and attention, you can harvest your own market-worthy carrots.

Splitting is one of the most common issues when it comes to growing carrots. It happens when a carrot develops an internal crack or splits due to uneven water uptake.

How To Avoid Splitting

To avoid this, drainage is key. You want to water evenly and consistently. Make sure the soil is slightly moist before planting the seeds and keep it at that level throughout the growing season.


Cracking is another common problem when it comes to growing carrots.
This usually happens when the outside layer of the carrot dries out faster than the inner layers, causing the outside to split.

How To Avoid Cracking

I know I’ve spoken about maintaining the watering your carrots already, but I can’t stress how important this actually is.

Keep your soil evenly moist and mulch around the plants to help maintain moisture levels.


Forking is another annoying problem that can occur when growing carrots. This happens when two or more roots grow together and create multiple root branches.

How To Avoid Forking

To avoid this, make sure you’re planting your carrots in loose soil that’s free of rocks and clods. Plant them at least 1 inch deep, and thin out overcrowded plants when you spot them.

Don’t these guidelines sound simple enough? With a little effort, you can enjoy a plentiful crop of fresh carrots right from your own backyard!

Why are Carrot Shoulders Green?

One of the most common problems gardeners encounter when growing carrots is the appearance of green shoulders.

This occurs when the carrots are exposed to too much sunlight, causing the shoulders of the carrot to take on a greenish hue.

While this discoloration doesn’t affect the taste or quality of the carrots, it can be unsightly and is often considered a sign that the carrots were not grown correctly. So, what can you do to prevent green shoulders from occurring in your carrots?

How To Avoid Green Shoulders

The best way to avoid green shoulders is to ensure that your carrots are not exposed to too much direct sunlight. Carrots prefer partial shade, so try planting them in areas where they will receive at least 4-6 hours of sunlight per day.

You can also use various methods to reduce sunlight exposure such as using row covers, building a trellis or using plastic mulch to reflect light away from the carrots. Additionally, planting taller crops nearby can help provide some shade for the carrots.

Finally, be sure to water your carrots regularly. Carrots need 1-2 inches of water per week, depending on the weather and soil conditions. The goal is to keep the soil evenly moist and avoid overly dry or wet conditions.

What is Running to a Seed

When it comes to gardening and growing carrots, one of the most common problems that can arise is when the carrots start to run to seed. But what does this phrase mean?

Run to seed is a term used to describe a situation in which carrot plants produce flowers before they reach maturity and before their roots are fully formed.

Carrots usually begin to flower when temperatures rise above 75°F (24°C). As the flower heads open and the pollen is released, the carrots will stop growing and their flavor will be diminished.

Fortunately, there are several steps that can be taken to avoid the dreaded run to seed problem.

How To Avoid Seed Problems


The first step is to ensure that your carrots have enough space to grow properly.
If your carrots are planted too close together, this can create a problem as the plants will be competing for resources.

Therefore, it’s important to make sure that there is at least 3 inches of space between each carrot plant.


The second step is to make sure that the soil you are using for your carrots is adequately moist.
Carrots need consistent moisture levels in order to grow properly, so if you live in an area with limited rainfall, then you may need to water your carrots more often.

Additionally, it’s important to make sure that you are fertilizing your carrots regularly to provide them with the nutrients they need to stay healthy.


It’s important to make sure that the temperature remains below 75°F (24°C) during the growing season.

Hot temperatures can cause carrots to run to seed, so if you live in an area with higher temperatures, then it may be necessary to find ways to cool down the area where your carrots are growing.

Common Pest and Diseases Associated With Carrots

Carrots are a popular choice among gardeners, but they can be vulnerable to certain pests and diseases.

While it’s important to take the necessary precautions to protect your carrots from these problems, it’s also important to know what they are and how to identify them.

Here’s an overview of the most common pests and diseases that can affect carrot crops, and some tips on how to avoid them.

Pests Which Affect Carrots

Carrots can be susceptible to several different types of pests, including aphids, flea beetles, carrot weevils, cutworms, wireworms, and slugs.

Identifying which pest you’re dealing with is the first step in controlling them.

Aphids feed on leaves and stems and can stunt or distort growth; flea beetles eat the foliage; carrot weevils bore into the roots; cutworms chew through stems; wireworms feed on roots; and slugs consume foliage and attack young seedlings.

How To Protect Against Pests

You can protect your carrot crop by using row covers, planting marigolds or radishes to deter pests, regularly checking for signs of infestation, and removing weeds from the area.

Diseases That Affect Carrots

Carrots can also be affected by various fungal and bacterial diseases, including Alternaria leaf blight, Fusarium root rot, powdery mildew, and black rot.

Alternaria leaf blight causes dark spots on the leaves and stem; Fusarium root rot causes the roots to rot and die; powdery mildew leaves a white powdery coating on the plant; and black rot creates brown lesions on the leaves.

How To Avoid Diseases

To reduce the risk of disease, it’s important to practice crop rotation, water properly, keep the area free of weeds, and use resistant varieties when possible.

By knowing which pests and diseases are common in your area and taking the necessary steps to prevent them, you can ensure a successful carrot crop.

What Happens When All My Seeds Sprout?

Have you ever planted a garden with carrots only to find out that all your seeds sprouted?
If so, you’re not alone! Many gardeners struggle with the common problem of having too many carrot seedlings.

While having an abundance of seedlings can be exciting, it can also create problems.

Too many seedlings can overcrowd the garden, causing issues such as poor air circulation, competition for resources and a higher risk of disease and pest infestation.

Fortunately, there are a few strategies that can help you avoid this problem. Here are some tips for dealing with too many carrot seedlings:

How To Avoid Sprouting Too Many Seedlings

Thin Early 

The best way to keep your seedlings from overcrowding is to thin them out early.
When your seedlings are young and their stems are still thin and weak, use a pair of scissors to cut off extra seedlings at the base.
This will give your remaining seedlings the space they need to grow properly.

Plant in Blocks

When planting your carrot seeds, space them in blocks rather than individual rows.
Carrots prefer to be planted in groups of 4-6 plants, as this allows for better air circulation and helps reduce competition for resources.

Use Mulch

Applying mulch around your carrot plants can help prevent weed growth and keep soil moist, which reduces stress on the plants and helps them grow healthier.

By following these steps, you should be able to reduce the number of carrot seedlings in your garden and ensure that your remaining carrots have enough room to grow properly. With the right care, you’ll be able to enjoy a healthy crop of carrots this season!

Why are My Carrots not Sprouting?

If you’re in this situation, don’t give up hope – there are some simple steps you can take to get your carrot plants growing again.


The first step is to make sure that you’ve planted your carrots in a sunny spot with well-draining soil. Carrots do best in a spot that gets full sun throughout the day and in soil that won’t stay soggy. If you can feel moisture when you press down on the soil, it’s too wet for carrots.


Another possible cause of non-sprouting carrots is planting too deeply. Carrot seeds need light to germinate, so make sure you’re only planting them about 1⁄4 inch deep in the soil. If you’ve planted them deeper than that, gently pull the dirt away from around the seedlings and cover them back up with a thin layer of soil.

Soil Temperature 

One other cause of non-sprouting carrots could be the temperature of the soil. Carrots prefer cooler temperatures, so if the weather has been exceptionally hot in your area, it could be preventing the seeds from germinating. Try shading your carrot patch during the hottest part of the day and water regularly.


If all else fails, try planting some new carrot seeds in a different spot. With these tips, your carrots should be on their way to being happy and healthy!


Growing carrots in the garden can be a rewarding experience. But with so many potential problems that can arise, it’s important to be prepared and take the necessary steps to avoid them.

By following these tips, you can ensure that your carrot crop is successful and healthy.

From soil preparation to pest control, there are many steps you can take to protect your carrots from disease and pests.

Additionally, proper storage and harvesting can help to extend the shelf life of your carrots.

With the right know-how and diligence, your carrot garden can thrive and provide you with delicious vegetables throughout the season
