Applications: The richer the soil, the larger and more beautiful the flower and plant. Since the plant reacts well to receiving fertilizers during its growth period, it is advisable to administer these in liquid form only during that time. In areas where frost occurs, it is better to plant the bulbs in pots that can then be kept in a frost-free location during the winter.
