Preparing for Summer: May Course Update

After the warmest March on record in U.S. history, April followed with unusually warm and extremely dry conditions. While the dry weather allowed us to make significant progress on several course improvement projects, it also required increased irrigation cycles to maintain healthy turf conditions. The extended stretch of warm, dry weather accelerated early-season turf growth and allowed the grounds crew to stay ahead on many spring maintenance priorities.

May, however, has brought a noticeable shift in weather patterns with much cooler temperatures settling into the region. As we move toward the most demanding turf-growing months of the season, the grounds crew remains focused on preparing the golf course for the busy summer ahead.

Deep-Tine Aeration

Deep-tine aeration of the greens was completed on April 27th. During the process, the greens were aerated to a depth of approximately 8 inches to help relieve soil compaction, improve oxygen exchange within the root zone, and promote deeper, healthier root growth. Following aeration, approximately 5 cubic feet of sand per 1,000 square feet was incorporated across the putting surfaces to help improve soil structure, enhance drainage, and maintain smooth, firm playing conditions throughout the season.

Deep-tine aeration is one of the most important agronomic practices performed on golf course greens. By creating channels deep within the soil profile, the process allows water, air, and nutrients to move more effectively through the root zone while reducing compaction caused by traffic and mowing equipment. These improvements help strengthen the turf during the stressful summer months ahead and contribute to healthier, more consistent putting surfaces over the long term. The greens have responded very well to the process and have now almost completely healed in, with putting quality and surface smoothness continuing to improve each day.

Drainage Project

The drainage project on holes #4, #6, #7, #11, the approach on #13, and valley on #15 has now been completed. The upgraded drainage system was designed to better manage excess water in these low-lying fairway areas, helping to reduce standing water after heavy rainfall and allowing the turf to recover more quickly following wet weather events. Golf Preservations installed a combination of smaller collection pipes to pull water from wet pockets and larger main lines to efficiently move water away from these problem areas.

Shortly after the majority of the spring work was completed, the course received a 2.5-inch rainstorm that caused significant washouts in many of the newly trenched areas. As a result, crews spent an additional two days repairing and stabilizing the affected sections. To help prevent similar issues moving forward, hay bales and erosion-control wattles were installed throughout the project areas. Once the fairway sod has sufficiently rooted in these will be removed. While we are hopeful that the extreme weather conditions experienced during the summer of 2025 will not repeat themselves this season, the new drainage improvements should greatly minimize future damage and improve overall course conditions during extended wet periods.

Crabgrass?

Intermediate ryegrass and bentgrass were interseeded into some of the fairway mud pits following last summer’s heat wave monsoon-like rain events. In addition, it was used to help mask dormant Bermuda grass fairway patches during the winter months when Bermuda naturally turns brown and becomes visually unappealing (click here for a previous post about overseeding bermuda grass). Intermediate ryegrass was selected because of its extremely quick germination and establishment rate, allowing damaged or thin turf areas to recover rapidly while providing improved turf density and appearance during cooler weather conditions.

Unlike permanent turf varieties, intermediate ryegrass is intended to be temporary. As temperatures rise and summer approaches, the ryegrass naturally declines and dies out, allowing the Bermuda grass underneath to fully transition back into active growth. This process helps protect exposed soil during the offseason while maintaining better overall playing conditions and aesthetics throughout the winter and early spring.

There have been several questions regarding whether the ryegrass currently visible in the fairways is actually crabgrass. The answer is no — intermediate ryegrass and crabgrass are two completely different grasses with very different growth habits and characteristics. Intermediate ryegrass is a cool-season turfgrass that grows in upright bunches with finer leaf blades and was intentionally seeded as part of our turf recovery and winter coverage program. Crabgrass, by comparison, is a lime green warm-season annual weed that grows aggressively outward in a flat, spreading pattern and typically becomes most active during the hotter summer months. In addition, a pre-emergent herbicide application was made to all playing surfaces earlier this season to help reduce crabgrass germination throughout the golf course.

At WHCC, goosegrass has proven to be a more significant challenge than crabgrass in certain areas of the course. Goosegrass is a late season weed (typically germinating in late July or early August) that thrives in compacted, stressed turf conditions and can become more visible during periods of summer heat. Our maintenance team will continue monitoring conditions closely and will make additional herbicide applications as needed throughout the summer to help control goosegrass pressure and maintain healthy playing surfaces.

Robotic Mowers

The new Husqvarna robotic mowers have now been fully installed and are currently operating on the driving range. These autonomous units are designed to provide consistent, daily mowing while helping improve overall turf quality and appearance. Because the robotic mowers cut smaller amounts of grass more frequently, they produce a cleaner, more uniform playing surface while reducing stress on the turf. 

In addition to the turf benefits, the robotic mowers improve operational efficiency by allowing the maintenance staff to focus more time on detailed course conditioning projects and other agronomic practices throughout the property. The units operate quietly, use significantly less fuel and labor than traditional mowing equipment, and can maintain consistent mowing schedules even during periods of rapid turf growth. As we continue to fine-tune their operation and coverage areas, we expect the robotic mowing program to provide long-term benefits in both course presentation and maintenance efficiency.

Thick Rough

The spring months always bring a variety of opinions regarding rough height on the golf course. While we work hard to manage growth and maintain consistent playing conditions, the reality is that rough grass naturally becomes longer and thicker during this time of year. In May and June, ideal growing conditions—including warmer soil temperatures, increased rainfall, and longer daylight hours—create a surge in turf growth. Cool-season grasses commonly found in the rough, such as Kentucky bluegrass, ryegrass, and fescues, thrive during these mild spring conditions. Increased sunlight also boosts photosynthesis, allowing the turf to grow aggressively and fill in areas that may have thinned during winter dormancy.

Spring rainfall plays a major role in this rapid growth cycle as well. Unlike the heat and drought stress often experienced later in the summer, turfgrass during the spring is rarely lacking moisture. Combined with seasonal fertilization programs designed to strengthen the turf for the upcoming golf season, the rough quickly becomes lush, dense, and healthy. Since rough areas are maintained at a significantly higher mowing height than greens or fairways, the grass naturally appears thicker when growing conditions are ideal. In addition, late fall and early spring overseeding programs help fill in bare or thin areas, particularly under tree lines, leading to even denser rough throughout the course.

The purpose of the rough is to challenge players by making recovery shots more difficult, but during late spring the rapid growth can occasionally make the rough more difficult than intended. Managing these conditions can become especially challenging during extended wet periods when saturated turf limits mowing opportunities. Without frequent mowing, the rough can quickly become overly thick and impact pace of play. May and June are some of the busiest months for the grounds crew as rough mowers are often operating daily to keep up with growth. As summer progresses, however, hotter and drier conditions—combined with competition from tree roots—typically thin the rough considerably, leading us back into our overseeding programs again later in the fall.

Summer Annuals

The horticulture team has been extremely busy over the past two months transitioning the landscape beds from spring into summer color. The tulip displays provided outstanding color through the Easter season before naturally reaching the end of their bloom cycle. Once the spring bulbs finished flowering, crews began removing the spent plant material and preparing the landscape beds for the installation of summer annuals and tropical plantings.

With the arrival of May, summer flower planting is now well underway throughout the clubhouse and pro shop areas. This season’s ornamental displays feature a wide variety of colorful and tropical plants, including cannas, petunias, New Guinea impatiens, crotons, majesty palms, zinnias, euphorbia, and many others. After planting is completed, fresh mulch will be installed to help retain soil moisture, regulate soil temperatures, and enhance the overall appearance of the beds. These seasonal improvements will help beautify the clubhouse and pro shop grounds for the summer season.

Spring Groundskeeping Update

March has been a roller coaster of temperatures on the golf course, keeping the grounds crew constantly adjusting from one extreme to the next. Warm, springlike days have encouraged early growth and brought golfers out in full force, only to be followed by sharp drops in temperature that slow everything back down. As I write this post we are sitting at a high of 28 degrees and this weekend the forecast has temperatures soaring into the 70s. Along with the temperature extremes Mother Nature has provided us with more than a couple storms leaving a decent amount of debris to cleanup. 

Mowing #1 green for the first time this year.

Wind

If there’s one thing the grounds department dreads most, it’s wind. Over the past few days, gusts reaching up to 45 mph have created a constant battle with debris, leaving the crew repeatedly clearing and restoring different areas. Playing surfaces have been blown off multiple times, requiring ongoing attention just to keep them usable. Several trees have also suffered damage—some completely uprooted—while a large pin oak lost nearly half its canopy after splitting apart under the force of the wind. We are in the process of removing the pin oak and it should be completely cleaned up by the weekend.

Drainage Project Update

As I wrote about in the last post, Golf Preservations was finishing up the drainage project on holes 11 and 15 when old man winter dropped a 5" snow storm in early December that brought the project to a screeching halt. Golf Preservations is adjusting their schedule to try and get the remaining two holes completed in early April. The drainage has worked well on the three holes that were completed last fall. #4 hillside , #6 valley, and #7 valley all drained very well after the late winter snows and the early spring rain events. This will improve drainage, allowing water to move off the fairways more quickly after summer rains and reducing the risk of standing moisture, hopefully, before the intense heat of the summer sun can stress and damage the turf.

Slit Seeding

The new Vredo slit seeder has been getting alot of use so far this spring. Most of the dead fairway areas from last summer's heat wave monsoons have recovered. There are some stubborn bare patches that we are slit seeding this spring. In addition, we are working to incorporate newer bentgrass varieties into the fairways to improve their overall health and enhance recovery during the stress of the summer months. These improved varieties are better equipped to withstand heat and wear, helping to maintain stronger, more resilient playing surfaces throughout the season.

Robotic Mowers

Four additional robotic mowers are being installed at the driving range, expanding our ability to maintain the entire area more efficiently. These units will be capable of mowing all key surfaces, including tee tops, surrounds, target greens, and the range floor. These mowers will help ensure consistent playing conditions and a high-quality appearance throughout the range. A technician will be on site in the coming weeks to map out the area and install the necessary software, after which the system will be fully operational and ready to go. This investment represents a step into the future of course maintenance, embracing innovative technology to improve turf care.

Additional Projects

Bunkers are currently being measured and replenished with sand to ensure they meet WHCC standards of 2 inches on the faces and 4 inches in the centers. We have already applied one load (22.5 tons) of bunker sand, with an additional load on order. Due to winter delays, the next shipment (sourced from Cleveland) is not expected to arrive until later this month as production has only recently resumed. Please keep in mind that even with proper springtime measurements, heavy rains can wash out bunker sand, making it challenging to maintain a consistent depth throughout the season.

The tulips are emerging rapidly thanks to the early stretch of warm temperatures. The horticulture crew has been busy mulching. If the current forecast holds, blooms could begin appearing by the end of March—or possibly even earlier— with hopes they will continue through Easter in early April.

The stump grindings from winter tree work have been fully cleared, and we are now in the process of filling the resulting holes with topsoil. To do this, we are repurposing the spoils from the late-fall drainage project. Sod will be ordered in early April to complete the project.

Mowing operations have also begun across many playing surfaces. Greens, fairways, and tees have each been mowed at least once, while the rough is beginning to actively grow and is scheduled for its first cut later this week.

March is always a crazy weather month. As conditions begin to settle into a more consistent warm pattern, we will transition fully into our daily maintenance routines. Until then, we’ll keep holding on tight and adapting as Mother Nature makes up her mind!

From Freeze to Thaw: A Busy Winter for the Grounds Crew

 It has been a busy winter season so far on the WHCC grounds. Wild temperature swings have occurred over the past few months, with snow followed by warm spells and a return to freezing conditions. During this time, several projects were completed, including the following:

Drainage

Golf Preservations began installing drainage on #4 hillside, #6 valley, #7 valley, #11, and #15 valley. The project was moving along at a steady pace during the end of November into the first days of December. Then this happened...

The December snows put a halt on this project and by the time it melted their H2-B workers were unavailable. Luckily, they were able to get 75% of the drainage installed completing all of #4 valley, #6 valley, and #7 valley. Golf Preservations started on #11 then the snow hit. We are hoping to have them back out in March to finish the drainage on the remaining holes, but it all depends on weather and when their workers are able to begin. 

There were a couple of rain events after completion on some holes, and drainage performed well. However, hole #11 experienced a washout due to excessive moisture flowing in from hole 10, combined with dormant Bermuda grass that was unable to establish roots this time of year to secure the sod. We patched up this area and added straw bales to slow down the flow of water. We are hopeful that these areas will perform much better this summer season because of the new drainage.

Verticuting Fairways

Around Christmas the weather pattern flipped and temperatures soared into the 50s and 60s for over a week. This allowed us to get a head start on some of the important cultural practices that we typically perform in early spring. One of these projects was verticutting fairways.

Verticutting fairways helps clean out excess thatch and organic buildup, which keeps turf healthier and playing better. It also encourages the grass to grow more upright by opening up the canopy and letting in more air, light, and nutrients. In the long run, it helps create firmer, more consistent playing surfaces golfers notice and appreciate.

Because of the warm temperatures we were able to complete half of the fairways which will help us get an early jump on this important practice. We were also able to get down some important winter sprays on the greens before old man winter showed up again.

Electric Installation

This fall, the Green Committee approved adding electricity to the driving range to support a larger fleet of robotic mowers. It was a 750 foot run from the grounds building to the driving range. A single-phase 208V, 40A feeder was installed to supply two outlets that will run 4 additional mowers to mow the driving range floor, tee surrounds, and eventually the tee tops. The ultimate goal is to not only mow the range with robotic mowers, but also eventually add in a robotic picker making the entire range system autonomous. With the first step of installing electric completed, step two will be to have the robotic technicians on property to map out the area. Then we will install reference stations, update software, and hopefully be mowing with robots by the spring. Stay tuned as we embrace the future with the introduction of these advanced robotic mowers.

Tree Work

Cold weather signals the grounds department’s switch to full arboriculture mode. This winter, we plan to remove 15 trees in-house and have 11 additional trees handled by a professional tree service. We are working on the USGA agronomist's tree report (CLICK HERE FOR THE REPORT). The tree removals recommended for holes 1–4 were completed this season, along with several trees affected by disease or decline. After the trees are removed, all stumps will be ground, the resulting holes filled with topsoil, and the areas either seeded or sodded. As of this writing, nine trees have been removed by the tree company, with the remaining two expected to be taken down before any further winter weather arrives. In addition, 13 of the 15 in-house trees have been removed and the rest will be completed in the next couple weeks.

In the short term, a major winter storm will keep the grounds department busy with snow removal. Once that’s behind us, the next projects on the horizon include installing steps on the #4 tee box and completing the remaining tree removals. This roller-coaster winter hasn’t slowed us down—if anything, it’s given us even more opportunities to improve the course for members to enjoy next season!
