Summer Solstice: Preparation for the Season Ahead

The summer solstice arrived at 4:24 this morning, and today in Southwest Florida, we will receive approximately 13 hours and 48 minutes of sunlight.

For golf course superintendents managing warm-season turfgrass, that is significant.

While the winter solstice remains the most critical agronomic date of the year, the summer solstice provides the conditions that help us prepare for it. In winter, we are managing bermudagrass during the most limiting period of the year. Day length is short, sun angles are low, air and soil temperatures decline, and turfgrass growth slows dramatically. During that period, our focus is preservation. We are trying to maintain healthy playing surfaces through the busiest part of the golf season while the turfgrass has the least ability to recover.

Summer provides the opportunity to prepare for that challenge.

The summer solstice marks the longest day of the year. The sun is higher in the sky, light intensity is greater, air and soil temperatures are consistently warm, and in Southwest Florida, summer rainfall typically becomes more frequent. These are the conditions warm-season turfgrass needs to flourish.

At Olde Florida Golf Club, our playing surfaces are primarily bermudagrass, a warm-season turfgrass species that responds best when sunlight, warmth, moisture, air, and nutrients are available in balance. During the summer months, the plant has the energy to grow, recover, and respond to the cultural practices necessary to build long-term turfgrass health.

This is why our summer work is so important.

Aerification, topdressing, verticutting, and other cultural practices are not performed simply because the calendar says it is summer or because member play is traditionally lighter. They are performed because this is the period when the turfgrass plant has the greatest ability to recover from disruption and benefit from the work.

These practices allow us to relieve compaction, manage organic matter, improve water movement, strengthen rooting, smooth and firm playing surfaces, and improve overall plant health. In many ways, the quality and resilience of the golf course during the winter season is directly connected to the work completed during the summer.

Winter is about survival.

Summer is about preparation.

That does not mean summer is without challenges. Heat, humidity, disease pressure, heavy rainfall, saturated soils, weeds, and intense thunderstorms are all part of managing turfgrass in Southwest Florida. However, from a growth and recovery standpoint, summer provides the environmental support we need to make meaningful improvements.

For my staff and me, the stress level is different in the summer. In many ways, it is reduced because the grass is actively growing and has a much greater ability to recover. At the same time, the workload increases significantly. The days are longer, the temperatures are higher, and the physical exertion required from the team is greater. Summer may be an easier time for the turfgrass plant to grow, but it is not an easier time for the staff doing the work.

For golfers, summer cultural practices can be inconvenient. They may temporarily affect appearance, smoothness, firmness, or playability. However, that temporary disruption is necessary. The work being performed now is an investment in the health, quality, and consistency of the golf course during the winter golf season.

The goal of this summer work is not only to improve turfgrass health, but to provide the best possible playing conditions when member activity is at its highest.

The summer solstice is a reminder that sunlight drives everything.

As superintendents, we can manage irrigation, fertility, mowing, traffic, drainage, and cultural practices, but we cannot create sunlight. When nature provides its longest days, warmest growing conditions, and seasonal rainfall, we must take advantage of that window.

The work completed during the summer helps the golf course flourish now, but more importantly, it prepares the turfgrass to remain healthy, resilient, and capable of performing during the peak golf season.
