Green Sand




A couple of seasons have now passed since green sand has been used to fill in divots on tee boxes and fairways. The green sand not only does a good job of camouflaging the many divots, especially on par three tee boxes and driving range tees, but also speeds up the rate at which new seedlings germinate. In the spring and fall, the daily temperatures are much cooler, slowing down seed development.  With the help of green sand, the small increase in temperature that is resulted in the darker sand is enough to increase seed development.

There are two types of sand that are used on the golf course throughout the season. One type of sand is very fine that comes from sand dunes north of Saratoga. This particular sand is used primarily for topdressing the tees and fairways. The other type of sand is hauled in from Colorado and consists of larger aggregates and allows for better drainage and plant growth and is used strictly on the greens at the Old Baldy Club. Both types of sand are kept separate to avoid contamination of the putting greens sand.

As each season arrives and all of those divots are made, large amounts of green sand are used. The green sand can be purchased for a pricy amount and our location drives the price up even more, forcing us to dye it ourselves. Normally the sand is made during the season, but is used faster than it can be made. The equipment manager, Paul Perue, is off for a couple of days allowing us to sneak in and make a mess while he is gone.

Each scoop of sand is put into an electric concrete mixer where at this point it is mixed with water and green dye. After it is properly mixed, it will be put into a bin (made of recycled pallets) and then moved into one of our storage areas. Seed is added later on right before the sand is applied to the turf. The plan is to get as many bins made as possible before the start of the season. The only setback so far is dealing with frozen sand and snow contamination, besides that the entire process is going good.


A quick update from the last post.
Here is a look at the greens samples taken two weeks ago, great progress.
