The Masters is played at a time of year when the warm season grasses are not playing at tournament level. So a lot of rye grass is seeded in the fairways and the roughs. And they use a high rate of seed to get good density. And I think we may assume that they use seed varieties that are uniform in texture and color. Why wouldn't they?
Well under that management plan you are going to have very green grass. I mean if you wanted Augusta to be off color at that time of year, given the circumstances, then you would have to paint it yellow or gold.
The one Masters tournament that I visited a few years back had some nice firm conditions as far as I could tell.
I honestly do not think that Augusta is vulgar or excessive in its use of fertilizers, water, or chemicals, as is so often implied. Now if you said that they use a heck of a lot of seed, that would be a fair statement, but the density of grass that they get from that heavy seeding is what helps the ball roll and bounce on those wide rolling hole corridors.
Probably if they used less seed, and less water and fertilizer, the density would be thinner, and if anything it would play less F&F. Certainly the ball would react way less to all of those amazing contours out there than it does under the turf management program that they are using. Anyways, I find it all very fascinating how much bad press Augusta gets with respect to it's color.
If I were to find one thing to be critical of at Augusta, I would say that they have probably graded and smoothed too much of the contour out of the landing areas. But that's being picky.
