Do Desert Willow Tree Roots Grow Down & Deep Or Spread?

Question

I’m thinking to transplant one between an adobe outside wall and a cemented area. Do I need to worry about eventual disruption of the cement? Cement area is used for outdoor classes. Where Willow is now is too crowded. A seed just landed and it’s growing exponentially. thank you.

Answer 1

According to the article below, it is safe to plant near walls and paving. However, leave room for a canopy that spreads up to 25 feet and the height can reach 30 feet. They can be pruned each year for a compact shape.
