Where Did Carrots Come From?

Where Did Carrots Come From?

About a thousand years ago, in 200 BC in a country now known as Afghanistan, people started growing carrots. Back then, sweet orange carrots did not exist yet.

The farmers from this period planted yellow, white, and purple varieties which usually tasted woody and bitter. Furthermore, it was used for medicine rather than as a staple vegetable. 

It was only in the 16th century when Dutch farmers decided to genetically modify carrots to become sweeter and discovered the orange variety. By this time, carrots were only served in the royal courts and the homes of the rich.

Carrots were only cultivated in the 19th century and became available in any home.

How To Do It?

A Step-by-Step to Grow Carrots Indoors From Seed

  1. Prepare the planter

    The depth of your pot will depend on the type of carrot that you are going to plant. Let’s say, you are planting the shorter types, an 8-inch pot will be enough. However, if you are not sure of how long the root will grow, using a pot that can hold about 12 inches of soil is the safest option.

    When you are done with that, place the planter or pot onto a tray. It should be deep enough to catch any excess water.

  2. Pour in the soil

    The next thing you have to do is pour in the soil which is either heavy or sandy. If you are unsure, you can mix sandy soil with mulch or organic compost. Make sure to loosen it to allow the carrot to grow.

    Remember that garden soil is too heavy for most planters, this is the reason why you mix it with compost or mulch. After pouring the soil into the pot, be sure to leave at least an inch from the rim of the planter.

  3. Plant the carrot seeds

    Before pouring in the seeds, poke three holes that are about an eighth of an inch deep and 2 inches apart on the soil. This will prevent the carrots from overcrowding. After you’re done with that, place seeds in each hole.

    Note that carrots have a low germination rate that some gardeners usually just sprinkle the seeds onto the pot directly. When the plant starts to grow, they remove the thinner stems to stop overcrowding the healthier crops.

    Unlike other types of vegetables, such as the asparagus, sowing carrots in a larger pot at the onset is the usual practice. Since carrots do not transplant well and might die when moved from one planter to another.

  4. Place in a sunny area

    Since carrots need the sun, place it in an area of the room where it gets to bask in the sunlight for at least six hours. Doing so will help your carrots grow well.

  5. Keep the soil moist

    As seedlings, carrots love moisture, so while they are growing, the soil should be well irrigated. However, they can also be susceptible to a fungi disease called the Pythium fungi.

    When your carrot is afflicted with this, the roots will appear to have dark to black colored cavities all around it. It usually infects the plant early on in its development. So try not to overwater the plant.

    Another method to prevent this is to water it with chamomile tea. Chamomile is a natural and mild anti-fungal agent. You can boil two packets of tea and it should be enough. You can also do a one-time dusting of charcoal or cinnamon on to the soil to prevent fungal growth.

  6. Wait for it to grow

    The last step is to wait for your seedlings to grow. Make sure to remove all the thinner stems. Depending on the variety, you will have to wait 60 to 80 days or two and a half months for the carrots to mature. You can also harvest earlier if you want baby carrots, instead.

    When watering the plants after its seedling stage, the roots become a little more mature which is usually about two inches in length. An inch of water should be enough for a week. Although, you have to ensure that the soil is soaked through to the roots.

How To Harvest Carrots?

As mentioned before, it should take at least two and a half months before the carrots are ready to be harvested. If you want to eat baby carrots, you can harvest after 60 days. So, keep your seed packet for future use.

The time it takes for the plant to mature is usually stated at the back of your seed packet. Once you are sure that the carrots are mature enough, you can start harvesting.

Start by loosening the soil around the plant and slowly pulling it out. If you just directly pull on its leaves, the chances are you will only be pulling out its leaves.

Once you are done with that, cut off the leaves and leave out at least an inch or two of stem on the carrot to help keep it fresh longer. You also don’t have to harvest all of the carrots at one time.

For example, if you can only consume about three carrots in a week, you can choose to harvest only that amount and leave the rest. You can choose to delay the harvest of the other plants for about a week or even more in colder temperatures.

Final Thoughts

The tips above are designed to help you successfully harvest your first carrots. So, start growing carrots indoors now.
