Daffodil bulbs need a moist and drained fertile soil during the growing season, but dry for dormancy, so much so that some varieties are transferred to a gravelly soil in this period. To grow your daffodils optimally, plant the bulbs in fertile soil, enriched with mature manure, preferably in partially shaded positions. The fertilization foresees a fertilizer to prevalence of phosphorus and potassium, in the measure of around 50 grams to the square meter. The best period is in September, digging a deep hole three times the length of the bulb, at a distance of 15 cm from each other. They are then removed from the ground when they begin to bloom less abundantly and the leaves turn yellow. Because this operation takes place in September, the bulbs can be replanted immediately, or stored in containers until the next transplant: this operation must be done at least every two to three years for the varieties that produce cut flowers. For storage you will need to remove the covering, the foreign leaves and the roots. Simultaneously with this operation it is also possible to proceed with the division of the bulbs, the most used multiplication technique for daffodils. If the daffodils are grown in pots, glass or in apartments, they will flower from November to May. Also in this case we advise not to drench the soil and avoid water stagnation.
