2. Whether looping stolons indicate a problem or are a normal part of the grass's growth
3. Practical steps to manage and maintain your lawn's health

Step-by-Step Guide

Identify the looping or spreading runners that emerge from the existing grass, often along edges or in areas with limited space.

1. Observe the stolons poking out of the ground, especially in tight spots or along borders.
2. Note that these runners are a natural part of St. Augustine grass's growth habit and are not necessarily problematic.

Assess whether the runners are leading to overgrowth, crowding, or spreading into unwanted areas.

1. If they are spreading into areas where you want less growth, consider management options.
2. If they are contained within desired boundaries, they are part of healthy turf development and do not require intervention.

If you decide to control the stolons, follow these steps to manage the spread effectively.

1. Use a sharp lawn edging tool or mower to trim the runners at the desired boundary.
2. Regularly monitor areas where stolons tend to spread and prune as needed.
3. Adjust watering and fertilization practices to promote balanced growth and reduce excessive runner proliferation.
