Shade Tree with Non Invasive Roots

We just purchased an old home, severely neglected and overgrown, and removed 3 trees. Two highly root invasive Liquidamber's and one Silk Oak. Both extremely messy and roots too invasive! The Liquidamber roots actually split a huge boulder!!

Any suggestions for a fast growing shade tree about 10 feet from slab with non-spreading roots?

Less mess the better as the tree will shade the house in the afternoon, and a big deck in the morning. The deck is huge and the current Silk Oak drops horrible seeds constantly! We took one out, but left one so we'd have a little shade.

How tall and wide would you like? Evergreen or deciduous? Al

RE: Shade Tree with Non Invasive Roots

Deciduous is fine because warmth in winter is desirable, but a good evergreen would be nice too. The house is about 2 1/2 stories above the tree site, so we'd like the roof to get some shade to assist in keeping the house cooler in hot summer months. Any suggestions will be welcomed!

Have a look here at the Cal Poly Tree Selector. It can help narrow down your choices, then ask again here for performance in your Sunset zone.

My local nurseryman says this of


"Here's one of my favorite trees. This is a hybrid between the Red Maple (which won't succeed locally) and the Silver Maple (which performs well but has yellow fall color). This medium to large tree grows quickly with large, lobed leaves that are green above and silvery below during the growing season. The reliable fall foliage color is magenta and rose. This sterile hybrid makes no flowers or seed pods. The roots are relatively benign and don't send up suckers. This tree is not without faults. It's long slender branches are subject to breakage from ice storms in colder climates. Locally, it's nearly perfect.

Situate in sun. Provide decent soil and average moisture."

He's in Sunset 20 not 19, but the two zones are pretty close in condition.

Part (not all, but part) of avoiding root problems is watering properly so you don't end up with surface roots. If the soil is moistened only 1" down, even well-behaved trees must get into that 1" to get water, and they will do it!

Wow! Fantastic link! Thanks so much! I'll be using that link for many other places in our 1.4 acre rocky hillside property!
