From Seed

• Willow seeds are considered recalcitrant. A seed with recalcitrant properties does not tolerate drying after seed development and does not store well. Willow seed is contained in a capsule and should be collected as soon as the capsules reach maturity. You will know the capsule has reached maturity when the color changes from green to yellow. Plant the seed, as they are viable for only a few days.
  
  

From Cuttings

• This form of propagation is the best way to cultivate a new plant from a mature specimen. Willows root easily and give a clone of a particular specimen tree that you have selected. Take up to a 6-foot hardwood cutting in early spring and promptly plant in moist soil. The twig should take root in one month if adequate moisture is provided. By the end of the growing season, you will have a fully rooted cutting.
  
  

Growing Tips

• Selecting a proper site is key in the long-term success of the health of your new willow tree. Select a site with good soil moisture content and full sun to partial shade. Adding compost to the planting hole corrects soil issues. Willows have large, fibrous root systems and should not be planted near foundations, water lines or other underground pipe systems. Willows tolerate many pH levels, but do not like shallow soils. Prune your new willow tree in summer or fall.
  
  

Making Willow Water

  Willows not only root themselves easily but help other plants root. Take about two cups of pencil-sized twigs and cut into 1- to 3-inch lengths. Steep the twigs overnight in boiling water. This solution lasts up to two months if kept in an airtight container. Soak cuttings in the willow water or water newly planted cuttings with it. Willow water helps root difficult cuttings, such as roses, azaleas, lilacs and summersweets.
