Backyard Putting Greens 201 — Design, Build, and What to Spec
Beyond 'install fake grass.' Real putting greens have stimp ratings, undulation, fringe rings, and proper drainage. Here's how we build them.
Stimp rating
The speed of the green. Tour-tournament greens run 11–13. Residential we target 9–11 depending on player preference. Achieved through turf pile height (lower = faster) and infill density.
Undulation
A flat green is boring after a week. We grade subtle 2–4" rolls into the sub-base before turf install. Cup placements at different elevations give real practice variety.
Cup placement
Minimum 4 cups for a useful green. PGA-spec 4.25" cups with brass collars. We pre-plan a chipping fringe ring around the green in contrasting turf for a polished look.
Base
6" compacted decomposed granite or class II road base, leveled to within 1/8" tolerance. Drainage tile beneath for monsoon runoff. Skipping base quality is why cheap putting greens get a hump in year 2.
Turf selection
Nylon pile (not polyethylene) for true ball roll. Avalon, SYNLawn ProPutt, or Tour Greens are the three we install. Avoid generic Home Depot 'putting turf' — wrong pile, wrong stimp, kills the project.
Investment
A 400–600 sf custom putting green with chipping fringe and multiple cups runs $18K–$35K installed. Lower if it's tied into a larger turf install.
