What our customers are saying…

  • Rated 5 out of 5 stars time and time again!

  • We have always had a nice garden, but for various reasons, taking care of all the chores that need to be done is beyond us now.

    We hired Thornbusch Landscaping to do the work we can no longer do. We can still plant flowers and make decisions about what goes where, but the Thornbusch crew does all the heavy lifting.

    They are prompt, courteous, and hard working. They are in-and-out quickly and they don't miss a thing.

    We held a wedding here and asked for a special tune up. Despite the terrible drought, our garden looked magnificent for our son and his bride.

    Paul and his crew have our highest unreserved recommendation and we find their rates very reasonable.

  • Hi. First let me reflect that we continue to get rave reviews on the landscaping you did for us last year at 21 Stones Creek Lane! Our experience with you was fabulous.
