Fennel (Foeniculum vulgare) is an annual herb. It is cultivated for its foliage and also for its root known as finocchio.
You can sow fennel seeds in a pot or window box (5 to 6 is enough) from March to September. Because it has a well-developed root system (finocchio), you should choose to plant it in a pot that is tall enough.
Dig holes 3 to 4 cm deep, place the fennel seeds in them and cover with soil.
The fennel needs warmth to grow properly.
It does not need frequent watering.
In summer, water it once or twice a week.
Greek name: Μάραθος.
