To make your Christmas tree last longer, you can follow these tips: 1. Make sure to water your tree regularly, as it needs moisture to stay healthy and vibrant. 2. Avoid placing your tree near heat sources, such as fireplaces or radiators, as this can dry it out. 3. Keep your tree away from direct sunlight, as this can fade the color of the needles. 4. When decorating your tree, avoid using too many heavy ornaments that could weigh down the branches. 5. After the holidays, store your tree in a cool, dry place until next year.
