The answer is yes, as long as you choose the right varieties and provide the right growing conditions. Although carrots are a cool-season crop that prefers mild temperatures and moist soil, with a little bit of planning and care, you can still grow them successfully in the summer. 

In this blog, we’ll explore the temperature requirements for growing carrots, and the heat-tolerant carrot varieties that can thrive in the summer heat. We’ll also discuss the growing conditions that carrots require and share some tips on how to grow them in the summer months. So, let’s dive in and learn how to grow carrots in the summer!

Will Carrots Grow in Summer?

Yes, carrots can grow in the summer, but it’s very important that you choose heat-tolerant varieties. These varieties are generally shorter and have a more compact shape, which helps them to conserve moisture and withstand heat stress. 

In addition to choosing the right varieties, you must provide the right conditions to grow carrots in Summer. This includes planting them in well-drained soil that is rich in organic matter, watering them deeply and regularly, and providing some shade or mulch to help retain moisture in the soil.

Carrot Growing Temperature in Celsius

Carrots are a cool-season crop and they grow best in temperatures between 15 degrees celsius to 20 degrees Celsius (59 degrees F to 68 degrees F). But it should also be mentioned that they can tolerate temperatures as low as 7 degrees C (45 degrees F) and as high as 30 degrees Celsius, but temperatures outside of this range can result in slower growth, poor root development, and other issues. When temperatures are too high, carrots can become woody, and bitter, and develop a soapy flavor. 

The best temperature to grow carrots is between 15 degrees C to 20 degrees C (59 degrees F to 68 degrees F). By monitoring and maintaining the right temperatures for your carrots, you can ensure a successful and bountiful harvest.

How to Grow Carrots in Summer? 8 Steps

Growing carrots in the summer can be challenging, but it’s possible with these 8 steps! 

Choose Heat-Tolerant Carrot Varieties

To grow carrots in summer, start with carrot varieties that are specifically bred to tolerate high temperatures and drought conditions. Due to their shorter and compact shape, they are able to conserve moisture and withstand heat stress better.

Plant in Well-Drained Soil

Carrots prefer loose, well-drained soil that is rich in organic matter. Make sure to remove any rocks or debris from the soil before planting, as these can cause the roots to fork or become misshapen. Carrot is a root vegetable that can grow faster in well-drained, loose, loamy, or sandy soils.

Sow the Seeds Differently

Carrot seeds should be planted ½ to ¾ inches (1.5 to 2 cm) deep in the soil, which is shallower than the typical planting depth of 1-2 inches (2.5-5 cm) for cooler temperatures. Planting the seeds too deep can result in poor germination, as the seeds may not be able to receive enough moisture to sprout.

Water Deeply and Regularly

Carrots need consistent moisture to grow properly, so make sure to water them deeply and regularly, especially during periods of drought. Avoid overwatering, as this can cause the roots to rot. 

Provide Some Shade or Mulch

As you are growing in the warm season, you must follow this point. Carrots prefer cooler soil temperatures, so providing some shade or mulch can help to retain moisture and keep the soil cool. You can use straw, leaves, or grass clippings as mulch.

Provide Enough Sunlight

Carrots thrive in direct sunlight and typically require six to eight hours of it daily. However, in the summer when temperatures are high, providing some shade or planting them in filtered light can help keep the soil temperatures cooler during the hottest part of the day. 

Thin out The Seedlings

Once your carrot seedlings have sprouted, thin them out so that they are spaced about 5-7cm (2-3 inches) apart. This will give them room to grow and develop properly.

Fertilize Sparingly

Carrots don’t require a lot of fertilizer, but you can add some compost or a balanced fertilizer to the soil before planting. Avoid using a fertilizer high in nitrogen, as this can cause the carrots to develop too much foliage at the expense of the root.

By following these tips, you can successfully grow carrots in the summer and enjoy a fresh harvest of this nutritious and delicious vegetable.

What Climate Do Carrots Grow in?

It’s a cool-season crop that grows best in mild temperatures. In general, carrots can be grown in a wide range of climates as long as they are planted during the appropriate season and provided with the right growing conditions. It depends on the climate, however, what types and techniques are necessary to grow them. Warmer climates, for example, may require heat-tolerant carrot varieties and adjusting planting depth and watering frequency for drier soils. For carrots in colder climates, it is recommended that they be mulched or covered to prevent frost damage.

What Growing Conditions Do Carrots Require?

To grow carrots successfully and produce high-quality, flavorful roots requires specific conditions. These are some of the key conditions carrots need to grow:

  • Soil: Carrots prefer loose, well-draining soil with plenty of organic matter and it should be deep, with no rocks or other obstructions.
  • Sunlight: Carrots need at least 6 hours of direct sunlight every day to grow properly and can tolerate partial shade.
  • Water: Carrots also need consistent deep water once or twice a week, depending on the weather conditions. 
  • Temperature: Carrots prefer cool weather and can tolerate light frosts. They grow best when temperatures range between 15 to 21 degrees Celsius
  • Soil pH: The soil pH should be between 6.0 and 6.8. 
  • Fertilizer: Carrots are light feeders and don’t need much fertilizer. You can use a balanced fertilizer or one that’s higher in phosphorus and potassium than nitrogen.
