If the idea of a broad and shimmering weeping willow tree gracing your landscape is appealing, propagate a new willow tree from an existing willow. The propagation method for rooting a new willow from a cutting is simple enough for both novice and experienced gardeners to complete easily. Because willow trees grow quickly in a variety of soils and landscapes, you can soon have an expansive and handsome willow tree as a focal point in your yard.
Select a stem from a willow tree that is at least ¼-inch in diameter early in the spring. Choose a green stem with new growth and leaves and cut approximately 8 inches from the end of the stem with the pruning shears.
Remove the leaves from the bottom half of the stem. Peel away the bark on one side of the end of the stem with the knife to aid in rooting.
Select a new planting location for the willow tree. Careful selection at this point will enable you to allow the cutting to root without disturbing it at all. Select a location that receives full sunlight and that will accommodate a mature height and spread of up to 50 feet.
Insert the cutting into rooting hormone if you desire; however, rooting hormone is not required.
Place the cutting into the soil in the location you selected, pushing it approximately 3 to 4 inches into the soil. Make sure no stem foliage touches the soil.
Lightly spray the soil with water and keep the soil evenly moist while the cutting roots. It may take up to four weeks for the cutting to root.
