If you love having fresh flowers in the house but hate how quickly they wilt, you’re not alone. However, it’s easy to make them last longer with one simple item—a cotton ball! If your fresh flowers are hollow-stemmed, you can use cotton balls to keep them better hydrated by creating a flower plug. To do this, cut the bottom of each stem at a 45-degree angle. Next, turn the flower upside down and fill the stem with water. Plug the bottom of the stem with a cotton ball and you’re set! The porous cotton ball will allow the stem to better soak up the water from the vase. This works on any hollow-stemmed flower such as daffodils, tulips and amaryllises.
