The improved hybrid bermudagrasses and stargrasses should be harvested at 15 - 18 inches for the first cutting and then cut every 4 to 5 weeks. All hay equipment should be serviced and repaired before the hay season begins. A breakdown during harvest almost guarantees rain damage to the hay. Rain leaches soluble nutrients from the grass. It prevents the grass from drying quickly and thus, increases respiration loss and the possibility of mold.
Respiration is the breakdown of sugars, etc., in the plant.
This process occurs in all living plants, and it continues after the plants are out. In Florida's climate, rain damage is difficult to avoid. Frequent thunder showers in the summer will usually hit one or more hay harvests. However, an original or lab certified copy is still required for sales or change of ownership.
