In one sentence, describe what the following article is about:

Collect the branches in spring when new growths are forming on the tree. Look for fresh green shoots and branches that are skinnier than a pencil to use for your rooting tonic. Use a pair or pruning shears or a sharp utility knife to cut the willow branches at a 45-degree angle so the tree doesn't develop rot. You can use any type of willow for your rooting hormone. Don't use any dead branches since they won't contain any of the natural rooting hormones. When you're ready to plant your cuttings, dip the cut ends in the willow water solution and leave them to soak for at least 2 hours so they can absorb the nutrients. After they've soaked, put your cuttings in the soil so they can start to grow. You can also use the willow solution to water your cuttings during the first month of growth to help promote healthy roots and foliage.
Collect 2 cups (256 g) of young branches from a willow tree. Soak your cuttings in the willow solution for 2-3 hours before planting.
