Explanation:

Saffron corms like a well drained soil. Heavy clay soil must be avoided. The ideal type of ground is a neutral clay-calcareous or silty soil (PH 6 to 8). For small areas like a vegetable garden or simple borders, one can easily improve the soil by adding sand, peat or compost. The saffron bed must be in a sunny place, notably in autumn during the flowering stage.
