Fennel thrives best in sunny locations, relatively sheltered from the north and frost and at temperatures ranging between 18-25 degrees Celsius to have satisfactory growth. Although fennel does not have special soil requirements, for its planting we will choose topsoil rich in organic matter and perlite in order to achieve satisfactory ventilation and good drainage. Fennel can be planted directly from seed in the pot or with ready-made fennel seedlings that we will get from a nursery. If we plant fennel seed in the pot, it should be done at a depth of 1-2 centimeters and ensure temperatures around 20 degrees Celsius.
Fennel does not need frequent watering, as excess moisture can cause yellowing of the leaves and root rot. When we water it on sunny days, be careful not to wet its foliage because there is a risk of developing fungal diseases. Regarding the fertilization of fennel, it does not have special requirements for fertilizer as long as we enrich our topsoil with manure or compost. Alternatively, we incorporate 1 tablespoon of organic nitrogen fertilizer, once a month, to strengthen the growth of the fennel foliage.
