Keep your basket in a cool and dry room or shaded area. Avoid direct sunlight, extreme heat, dust, and water. All of these conditions may make your basket fade and brittle.
For a flower basket with floral foam, you don't need to remove the flowers. After receiving the flower basket, simply tidy up the surface of the flowers to make them appear more vibrant.
The flower basket is designed with waterproofing inside, and there's floral foam present. You can pour water from the corners or inject it through the gaps between the flowers (around 100ml or so) to keep the floral foam moist. Be sure to avoid direct sunlight to prolong the freshness of the flowers.
When a flower begins to wilt, remove the petals or the whole flower from the basket. Flowers bloom and wilt at different times. Removing wilted flowers will help to avoid the spread of bacteria to the other flowers.
