What was the putting green in the 1800s?
Up until the middle 1800s, putting greens were simply grass that was shorter due to sheep grazing there longer. Lawnmowers had not been invented yet.

How many different types of aerating are there?
First of all, there are probably as many as five different types of aerating practices, according to Adam Moeller, director of education for the USGA Green Section.

What irritates golfers more than anything?
What irritates golfers more than anything, of course, is when they show up for their tee time, only to find out then that the greens were recently aerated, or worst yet, don't discover it until they get to the first green.

How to prevent a delay in golf course opening?
The superintendent can apply a small amount of water to help remove the frost if the air temperature is not too cold. Running fans to blow air over the greens (the same fans used in the summer) will help to reduce frost problems if the temperature is only a few degrees below freezing. Greens with shade in the morning have lower soil temperatures and usually have the most frost on the grass. The removal of the trees that are shading the greens will help to reduce the delays from frost.
What happens when you walk on frozen turf?
The thawed layer will be saturated with water and becomes spongy. Walking on turf with this condition will cause foot printing and can cause the surface of the green to become uneven.

This damage in areas around where the hole is located on these days will appear as weaker turf later in the year.

Most superintendents topdress with straight sand, but others topdress with a mix of sand and organic matter, be it mushroom soil or peat. Some even topdress with 100 percent peat.
Where is organic matter needed for a green?
Some organic matter is needed between the root zone and crown of the plant . Part of the grow-in process is to accumulate organic matter near the top of the profile. Without this cushion, traffic would cause excessive wear on the turf. However, once the plant is in the ground for a while, it might begin to produce so much organic matter there’s no need to add more, Moore says. On mature greens, too little organic matter isn’t a problem the Green Section typically sees.
Does the Poa die from browning out?
Anderson keeps the soil as dry as possible, and the grass actually goes dormant on greens, browning out. Even the Poa goes off color and doesn’t die.

What weeds grow in over watered areas?
