Produce of the month: Carrots

If growing carrots is part of your business, you’re likely in the middle of the sowing season while the rest of the world goes on holiday. We wrote this blog post to celebrate one of the most common culinary staples worldwide, and the hard work that goes into cultivating it. Dig in to learn more about the carrot!

History

The first mention of carrots dates back some 1000 years to the area we now call Afghanistan. Back then, carrot roots were ivory and purple. In the 1600s, the dutch started cross-breeding ivory and purple carrots, to create the orange carrots we know and love today. The orange variety is called the “Rainbow carrot”.

Fun facts

-Just like blueberries, purple carrots get their pigment from anthocyanin, a powerful antioxidant.
- Carrots have a high beta carotene content, meaning they can help to improve your vision, immunity and skin.
- China, Uzbekistan, Russia, United States are the top 4 producers of carrots.
- California produces over 85% of all carrots grown in the United States.

Required conditions

🌡 Cool temperatures

- Ideal temperatures for carrots are around 75ºF during the day, and 55ºF at night.
- The roots reach ideal colour when the air temperature is between 60ºF to 70ºF.
- High temperatures cause poorly coloured low-quality carrots.
- Temperatures above 86ºF are likely to destroy the crop
- The stress of rapid increases in temperature causes carrots to bolt.

🌾 Moist soil at 60ºF

- Root growth is fastest at temperatures between 60ºF and 65ºF
- Carrots grow best in full sun and light, fertile, well-drained soil.
- Carrots are slow to germinate, but they are even slower and sometimes won't sprout at all if soil temperatures fall below 60ºF
- The soil should only be moist 3 inches deep to ensure the lowest chances for fungus to develop

*To monitor soil, we suggest using the CropSafe Daily Soils and Weekly Soils alerts.*

💨 Little wind

- Carrot seeds like to be kept moist, but sudden heat and strong winds mean the soil often dries out too quickly

*To monitor wind, we suggest using the CropSafe Wind Speed and Wind Direction alerts.*

Summary

Like many species of plants and vegetables, carrots are affected by the rapid changes in weather caused by climate breakdown. You can use the CropSafe app to monitor for these conditions and more.
