Which roots are least (or most) destructive?

robatworkuk · August 2019

I have in mind a shortlist of trees - I am going to plant one on the edge of my grass but it's next to a block paved path.

Is there a website where I can check on the tree roots to see which ones are least likely to cause problems to the path?

I think I read that coniferous trees have less invasive roots, and a pine tree is on my list along with Viburnum, Japanese Privet and others.

thanks

Not necessarily. If next to block paving you need to be concerned about the depth of rooting as well as spread, as some conifers are shallow rooting so will interfere, as will cherries and other fruit trees.

Are you talking about a tree or a bush tho’? Viburnum is most usually considered as a shrub.

There was a famous study done on tree roots and buildings in 1989, by cutler and richardson. But a book, and never places on the web. Closest is this research paper

Hi Hedera Helix... thanks for the reply. I've changed my mind on the tree and now I'm looking at one of these:

Will bear in mind your comments about fruit trees
