How to plant carrots and when to do it?

If we have to talk about a good time to sow carrots, that would be in late winter or early spring. However, when greenhouses are used, this can vary and be done in other seasons.
Here are some essential steps to get you started:
- Start by preparing the soil. Remember that it should be loose, deep and free of stones.
- Make furrows 1 cm deep and place the seeds about 2 cm apart.
- Cover lightly with soil and water gently.
- When the plants are about 5 cm tall, thin out the weakest ones and leave 8 to 10 cm between each one.

Care and recommendations for planting carrots

Now we will discuss the care you should consider when growing carrots.
Proper watering for carrots
Watering should be constant and moderate. It is important to maintain soil moisture, but without waterlogging it. Here you can use a drip irrigation system because it will help control humidity in the greenhouse.
Diseases and pests
Most crops can be affected by pests or diseases. In the case of carrots, you may encounter:
- Carrot fly.
- Aphids
- Fungi
To prevent them, it is recommended to rotate crops and maintain good ventilation.
Suitable fertiliser
Finally, we have fertiliser. In fact, you need to think about this before sowing because you must enrich the soil with mature compost or well-decomposed manure. Just avoid fertilisers with a lot of nitrogen because they will cause the leaves to grow more than the roots.
