large-cupped daffodil

Large-cupped daffodils (Narcissus 'Premiere') should be watered regularly during their growing season in spring and early summer. During this time, ensure that the soil remains moist but not soggy. Water the plants when the soil starts to dry out, usually every 7 to 10 days. Avoid over-watering, which can lead to yellow leaves and other signs of distress. Once the flowers begin to fade, reduce the amount of watering until the foliage turns yellow and dies back.

Large-cupped daffodils (Narcissus 'Premiere') require full sun in order to thrive. They should receive at least 8 to 10 hours of direct sunlight each day for optimal growth and flowering. Morning sun is preferable, as will exposure to some afternoon shade late in the season. If planted in full-shade conditions, these flowers will be less likely to bloom. It is important to note that this species of daffodil can be sensitive to excessive heat and may need protection from direct afternoon sun during the hottest part of the summer months.

Pruning large-cupped daffodils such as Narcissus 'Premiere' should be done as soon as the plant has finished blooming. This may occur in late May or early June, depending on your specific climate. Once the foliage has withered and died, carefully cut back the stems to a height of approximately 8-10 inches, but don't completely remove the foliage. Doing so will help to encourage the formation of new buds. For picky gardeners who want to prune their large-cupped daffodils with a bit more precision, wait until the foliage has died completely and then selectively prune only those stems that failed to bloom the previous season. Doing so will help ensure that your daffodil plants will come back with even bigger blooms the next season.
