1. Gather Tools You’ll Need
- Hand Tamper
- String Trimmer
- Safety Glasses
- 3 Foot Level
- Yard Rake (with flat metal side)
- Leaf Rake
- Square Nose
- Shovel and Hand Trowel
2. Level the Site
Select a level site or create one by reading “How To Level A Slope for Putting Green Installation.” Greens should not be placed in a depression or drain way.
3. Roll out green & check grade
Use a level to make sure the grade goes not exceed a 2” rise over a 10’ run.
4. Outline edge of green with weed eater, or edger
Always wear eye protection.
5. Roll up green
6. Weed eat grass inside the outline down to the dirt or roots
7. Rake or blow cuttings from outlined area
Cut ridges or roots if necessary. Fill any indentations.
8. Add 8 lbs. of base for every square foot of green
Add 2″ of 3/8″ minus gravel screenings, meaning your gravel supplier has passed gravel through a 3/8″ screen so only the smallest pieces pass through. This mix has small particles as well as gravel up to 3/8″ and every size in between. You’ll need about 12 pounds of gravel per square foot.
9. Create a gentle raised crown in the center for drainage
Use a leveling rake or 2×4 and rake the area smooth. No indentations should be present.
10. Compact the base
Use a water-filled roller or plate compactor rented from your home store or a hand tamper for small areas.
11. Check the base for levels and smoothness
The 3/8″ gravel holds contours much better than sand, so contouring is best done within the gravel base.
12. OPTIONAL: Additional paver sand can be added
Paver sand can add smoothness. You can create gentle contours in sand. Smooth with edge of level to final desired contour.
13. Roll out green and check smoothness and contours
14. Dig in cups with hand trowel or 4 ¼” hole cutter
OPTIONAL: If drainage may be an issue, dig 2-4 inches deeper than the length of the cup and add gravel. Top of the cup should be 1/8” below surface of the green. Keep dirt off green.
15. Soil too hard to dig cups with a hand trowel?
If digging is hard due to roots or rocks, mark hole and roll up green at hole. Then, chop up area by hole with a pick or round nosed shovel. Compact area flat and dig in hole.
16. After the cup is set in the ground, roll up green at hole and compact soil around the cup with the level
17. Roll out green and inspect contours and level cups
Cups can be leveled by stepping gently on their edges.
18. Clean and add optional markers or flags
Surface can be raked (leaf or carpet rake), blown, vacuumed with a beater bar or hosed off or gently pressure washed.
