To harvest Narcissus, also known as daffodils, you can follow these steps: 1. Timing: Narcissus plants usually bloom in the spring, so it's best to plan your harvest during this season when the flowers are in full bloom. 2. Prepare tools: Gather some gardening tools such as gloves, a spade or a garden fork, a trowel, pruning shears, and a bucket or container for the harvested flowers. 3. Choose the right flowers: Select the Narcissus flowers that you want to harvest. Look for healthy plants with fully open flowers and sturdy stems, as these are signs of maturity and optimal quality. 4. Cut the stems: Use pruning shears or sharp scissors to cut the stems close to the base of the plant. Leave at least 2-3 inches of the stem attached to the bulb.
