Q: Where should you not plant a willow tree?
A: Choose a growing site that receives full sun to partial shade, with moist, well-draining, slightly acidic soil. Pull any weeds and remove any turfgrass and debris. Do not plant near any underground power lines or sewers, since weeping willows have very long roots.

Q: Why are willow trees a problem?
A: Unlike most other vegetation, willows spread their roots into the bed of a watercourse, slowing the flow of water and reducing aeration. They form thickets which divert water outside the main watercourse or channel, causing flooding and erosion where the creek banks are vulnerable.

Q: Why should you not plant a weeping willow tree?
A: It grows very fast; often more than three feet per year. The weeping willow root system can spread up to three times the height of the tree itself, and these shallow roots go on to crack pavement, damage foundations, protrude above the soil, and invade water lines.

Q: How close can a willow tree be to a house?
A: For example, a mature willow tree will draw between 50 and 100 gallons of water per day from the ground around it, having a minimum recommended distance from buildings of 18m, but a birch tree, having a far smaller root system, may be planted far closer to a property without danger of damage.
