Can you grow carrots indoors in the UK?

Growing carrots indoors in the UK can be a fun and rewarding experience. Not only do they add a touch of greenery to your home, but they are also a healthy addition to your diet. Here are some tips to help you grow delicious and healthy carrots indoors in the UK.

Choose the right variety

When choosing a variety of carrots to grow indoors, it is important to consider the space available and the light and temperature conditions. Baby carrots are the best option for indoor growing, as they do not require deep soil and can be harvested early. Nantes and Paris Market carrots are great options for indoor growing, as they are both small and do not require a lot of space.

Choose the right container

Carrots can be grown in containers such as pots, window boxes, or grow bags. It is important to choose a container that is at least 12 inches deep, as carrots have long roots. Make sure the container has drainage holes to prevent waterlogging.

Soil and compost

The soil used for growing carrots should be well-draining, loose, and fertile. Adding organic compost to the soil before planting will provide the carrots with essential nutrients. Mix the compost with the soil and fill the container to within 1 inch of the rim.



Carrots should be sown directly into the container, spaced about 2 inches apart. Make a shallow trench about 0.5 inches deep, and sprinkle the seeds thinly along the trench. Cover the seeds with a thin layer of soil and gently water the container.

Light and temperature

Carrots require bright sunlight to grow properly, so choose a sunny windowsill that gets at least 6 hours of sunlight a day. The ideal temperature for growing carrots is between 16°C and 21°C. Avoid placing the container in a location that is too cold or too hot.


Carrots require consistent moisture to grow properly, so moisten the soil. Water the container regularly, but be careful not to overwater, as this can lead to root rot. Watering every 2-3 days should be sufficient, depending on the temperature and humidity. The alternative is to create a hydroponic system, something I’ve been planning on my kitchen wall – I think it would look awesome but my wife disagrees.


Once the seedlings have emerged, thin them out to leave about 1 inch of space between each plant. This will allow the carrots to grow properly and prevent competition for nutrients, which can create problems.


Carrots are usually ready to harvest after about 10-12 weeks. To check if they are ready, gently pull one out of the soil. If it is the desired size, the others should be ready as well. Gently pull the carrots out of the soil, not damaging the roots.
