5. What are problems on old greens?
1. Slower speeds
2. Inconsistency between greens
3. Need to tailor-make maintenance for each
green
4. Different changes happened to each green
5. Sizes/design differ from original
6. Not meeting current standards
7. Old and tired.

6. Let’s not judge too quickly…
it could be a problem that can be
easily fixed.

7. What causes problems?
 Grass that are prone to diseases
 Mixed types of grass
 Poor construction
 Old design
 Poor maintenance practices over the
years

8. Older greens can be disease prone

10. Prone to disease; why?
 Grass variety – not best choice
 Mixed grass
 Water not flowing / penetrating
 Compaction issues – surface or pan.
 Shade

11. Simple disease

12. Compaction over the years & shade
caused by now-tall trees

13. Drainage problems

14. Poor maintenance

15. Bad construction

16. Black layer

17. Mixed grass

18. What can you choose to do?
 Nothing.
 Extra cultural practice
 Change surface/grass
 Renovate parts of or only a few greens
 Rebuild all.

19. Do nothing if you get what you want

20. Extra cultural practice
 More aggressive
 Deeper aeration
 Scarifying instead of just
dethatching.

21.  Repair only parts of the green

22. Change only a few greens
 This problem green
 the worse three, six or nine greens.

23. Change all 18 greens
 Maybe by doing two greens per year
 But your golf course is always a “work
in progress” until complete all 18
 Or 6 or 9 greens a year: not too long.
 Ensure grass are from same source!

24. Do it in phases

25. Some clubs: Bite the bullet.
 Do all 18 greens one shot
 Build temporary greens
 Or Close the course

26. Why need to do?
 Because it may spread: disease
 Because it may spread: mixed grass.
 Because it will not go away on its own.
 Because it damages the club’s name
 Because it damages the GM, committee and Supt’s
reputation.
 Because it is annoying to members or regulars.

27. How?
 Build temporary greens at all holes or,
 Turn one long par-5s into two holes:
one par-4 & one par-3, or
 Build a temporary hole (if you have
space)

28. Can also do half a green at a time.

29. But may end up with Same but different
Tifdwarf on 1 green

30. Closing
 Me. Who I was.
 Symptoms of a problem green.
 Usually old but not all
 Why greens give problems.
 What can be done.
 Options on how to do
