Propagation by Cuttings

Willow trees are often propagated through cuttings, the most popular method. This method involves taking willow cuttings from the hardwood of an existing tree and then rooting them in either soil or water. 

  • To propagate a tree, select a young and healthy branch. At least 6 inches in length and 1/4 of an inch in width.
  • To stimulate the development of new roots, cut the branch at an angle just below a leaf node.
  • Remove any leaves still connected to the lowest part of the stem.
  • Soak the cut end with the rooting hormone to promote roots.
  • Then, place the cutting in a pot with well-draining soil, water it well, and cover it with a plastic bag to keep it moist. 
  • Avoid direct sunlight, and keep the pot warm and bright. Maintain wet soil.
  • In a few weeks, roots will start developing. Transfer the cutting to a bigger pot when you see some strong roots.

Propagation by Layering

Propagation by layering is another popular method of propagating willow trees. This technique includes bending a branch down to the ground and coaxing it to form roots while it is still linked to the parent plant. Here’s How to propagate willow trees

  1. Choose a flexible, healthy branch from the tree you wish to propagate. To ensure proper growth, it is recommended that the branch has a diameter of at least 1/4 inch and is long enough to reach the ground.
  2. Gently bend it downwards and create a small incision on the lower side where it meets the soil.
  3. Spread some of the rooting hormones over the cutting.
  4. Cover the cut area with soil and anchor the branch to the ground with a U-shaped stake.
  5. It is important to water the area adequately and to keep it moist. You will notice fresh growth in the branch throughout the next two weeks.
  6. Once it grows roots, cut the branch from the parent plant and transfer it.

Propagation by Seed

Propagation by seed is the least common method of propagating willow trees. It involves collecting seeds from an existing tree and planting them in moist soil. Here’s how to do it:

  1. Collect seeds from an existing willow tree. Choose fresh and healthy seeds.
  2. For the best chance of getting the seeds to germinate, soak them in water for a full day.
  3. Sow seeds in a container filled with well-draining soil. To increase the humidity, place a plastic bag over the pot.
  4. Place the container in a warm, sunny location. Don’t allow the soil to get too dry or too wet.
  5. The seed will grow in a few weeks. When the seedlings have developed strong roots, move them to a bigger pot or the ground.
