A few of you have asked me why some of the rough looks yellowish and mottled around select bunkers and greens. Each spring, we apply a pre-emergent herbicide to prevent crabgrass from germinating in those areas, along with a three way broadleaf herbicide. The holes where this yellowing is happening is where this application took place before an unexpected freeze the following night, causing tip burn on the leaves of the plant.
This tip burn is superficial in nature and the plant should grow out of this injury. We have applied fertilizer to help recovery along, and the warmer weather we are experiencing now should allow this injury to heal. If you have any questions, please feel free to contact me. Thanks!
