Hybrid willows are fast-growing trees, with weak wood and aggressive root systems. In fact, the hybrid willow's root system is a notorious invader of water lines and sewer and septic systems. Keep this in mind when choosing a planting location. Another aspect of the tree to be mindful of is its overall size in maturity: It can grow to 100 feet tall. Willows require a lot of sunshine and water in order to thrive, and the hybrid willow is no exception. The tree is extremely easy to propagate from cuttings taken in the spring, right before the buds break.
Cut a twig from the hybrid willow tree. It should be at least 10 inches long, cut from a dormant branch.
Dig a hole in the soil and bury the cutting, with the buds pointing up, as deeply as possible. The cutting will form roots along the entire length that is buried under the soil.
Water the cutting well and keep the soil moist, not soggy. Your hybrid willow cutting should root within one month.
