You can put a variety of things in a wooden vase, including flowers, plants, and even branches. Wood is a very versatile material that can be used for both decorative and functional purposes. When choosing what to put in your wooden vase, consider the overall look you are trying to achieve. Flowers are always a popular choice for vases, but you can also get creative with other items like plants or branches. If you are using fresh flowers, make sure to change the water regularly to keep them looking their best. You can also add some rocks or gravel to the bottom of the vase for extra stability.
