large-cupped daffodil

Large-cupped daffodils require weekly watering and should receive about 1 inch of water per week. It is important to water the plant deeply, providing enough water to get to the roots of the plant. It is recommended to water in the morning so the leaves have time to dry out before nightfall. During dryer periods, the daffodil may need to be watered more often. If the soil is dry several inches below the surface, it is time to water.

Large-cupped daffodils need full sun in order to thrive. They will need at least 6 to 8 hours of direct sunlight per day. It is important to provide full sunlight during the late winter and early spring months when they are actively growing, as the plant needs the sunlight to form flowers. During the summer months, the plants can be moved to a shadier spot if temperatures become too hot.

Large-cupped daffodils should be pruned in late autumn or winter, once their foliage has died back and the bulbs have been allowed to replenish their nutrients. Pruning should involve the removal of the seedheads and dead foliage, as well as any foliage that is die-back, yellow, or damaged by disease or pests. Cut each stem back to within an inch or 2 of the base of the bulb, ensuring that none of the bulbs are exposed. This will help prevent any new growth from being damaged.
