Watering Guide

Hydration is Key

Proper watering is essential for the health of St. Augustine grass. During the growing season, this grass type requires about 1 to 1.5 inches of water per week. This can be achieved through rainfall or irrigation. It's best to water early in the morning to minimize evaporation and fungal diseases. When watering, ensure that the soil is thoroughly saturated to encourage deep root growth. If you notice brown patches or a lack of growth, it may be a sign that your grass is not receiving enough water.

Mowing Tips

Keep Your Lawn Neat and Healthy

Mowing St. Augustine grass at the right height is crucial for its health and appearance. The recommended mowing height is between 2.5 to 4 inches. Mowing too short can stress the grass and make it more susceptible to pests and diseases. Frequency of mowing depends on the growth rate, but generally, mowing every 1-2 weeks during the growing season is ideal. Always make sure your mower blades are sharp for a clean cut, which helps prevent damage to the grass.
