Jacaranda Roots

[Maeve]

I have a Jacaranda about 12 feet high and want to extend my paved area closer to the tree. What is the root system of a Jacaranda like? Does it spread widely on the surface or does it go deeper? Can I put root guard around it? AT what distance from the trunk? Thanks. Maeve

Hello, Maeve. Ken here with The Home Depot in the Chicago area.
Your Jacaranda tree is so beautiful when it flowers. I don’t know how
close you want your paved area to the tree, but a Jacaranda will get
25-40 feet high and 15-30 feet wide. 90% of its roots will be in the top
three feet of soil. They will spread to 30 feet wide or greater. Paving
too close to the tree or putting down a root guard will inhibit water
absorption and possibly the stability of the tree in high winds. I hope this
helps and keep me posted on what you decide to do. Take care.
