Not the most flattering look for sure but this is the result of a heavy sand topdressing with seed and fertilizer on the previously mentioned troubled areas on greens. Sand topdressing is important in these areas for a variety of reasons. To mention a few would be:
-Protection of the existing plants. With no other plants around a grass plant it becomes more susceptible to outside stresses (mower damage, wind damage, traffic, etc.). It is important to protect the crown of the plant where the plant meets the soil.
-Encouraged lateral growth. Bentgrass moves through underground lateral stems called rhizomes. The topdressing gives them a better soil medium to move in.
-Decomposition of the algea (black mat) covering these areas. The less algae the quicker desired plants can move.
This will be a regular occurrence every couple weeks until we are able to get these areas healed. Putting conditions shouldn't be too much of a concern. Putts should roll through these areas somewhat smoother than the clumpy patches that inhabited these areas before.
