large-cupped daffodil

Large-cupped daffodils such as 'Passionale' prefer a well-drained soil with consistent moisture. During the growing season, water the plants when the top 1 inch of the soil begins to dry. Make sure to soak the soil so it is evenly moist, avoiding areas of oversaturation and pockets of dry soil, as this can increase the risk of disease. During the summer months, water once every 7-10 days for optimal results. Once the leaves begin to die back in the late summer/early fall, reduce watering to encourage bulbs to go dormant for the winter.

Large-cupped daffodils like Narcissus 'Passionale' need at least 5 hours of direct sunlight a day in order to thrive and flower. To ensure that they get the light they need, it is best to plant them in a location that gets full sun throughout the day or partial sun in the morning and afternoon. Keep in mind that during the summer months, plants need more light due to the longer daylight hours. It is also important to note that the plant should not be placed in a location that receives too much heat since this can lead to stress on the plant.

Large-cupped daffodils should be pruned immediately after the flowers have finished blooming. Cut off the dead flower stalks at the base of the plant and discard them. Pruning in late summer or early autumn helps to promote vigorous vegetative growth such as thick foliage and large flowers. To prune, remove some of the excess foliage and flower heads from the main stem, leaving only a few healthy stems. This encourages the plant to grow new, healthy stems, which will result in larger, more robust flowers the following year. Proper pruning can also help the plant flower for a longer period of time. After pruning, apply a balanced fertiliser to help keep the plant healthy and promote stronger growth.
