Golfers are often reminded to drink plenty of water before teeing it up on a hot summer day. Similarly, putting greens also need to stay hydrated. Typically, putting greens are irrigated at night or early in the morning.
Hand watering is the most effective and accurate way to water putting greens. Even with a state-of-the-art irrigation system, certain areas on each putting green will need more water than others – e.g., mounds and high-traffic areas.
The reason for liquid fertilizer use is the heightened expectations of putting surfaces, the area of a golf course that receives special focus regarding fertility programs. “They’re spoon-feeding,” Gross says about superintendents. “Instead of a half-pound once a month on the greens, they’ll apply a tenth of a pound once a week.
We do it in June, July and August, and the first week of September is liquid for the greens.” Hevey always uses a granular fertilizer on his tees, which are cut at higher heights than the rest of the course.
Chlorothalonil 720 Select is intended to be diluted into water, then applied to crops by typical agricultural spraying techniques. ALWAYS APPLY THIS PRODUCT IN SUFFICIENT WATER TO OBTAIN THOROUGH, UNIFORM COVERAGE OF FOLIAGE AND CROP SURFACES INTENDED TO BE PROTECTED FROM DISEASE.
Apply Chlorothalonil 82.5 WDG in 90 to 450 gallons of water per acre (2 to 10 gallons of water per 1,000 sq ft) for tees and greens and 30 to 450 gallons of water per acre (0.7 to 10 gallons of water per 1,000 sq ft) for all other turf.
Chemical Control Consider a preventive fungicide program for tall fescue and creeping bentgrass when conditions favor disease development. For best results, preventative applications should be initiated in the late spring or early summer when night temperatures consistently exceed 60°F.
Most systemic fungicides move less than an inch toward the tip of the plant or may just move from the upper to the lower side of the leaf. Use shorter spray intervals during weather conducive to plant disease. Each plant disease has its own “personality” and thus prefers different weather.
Avoid watering your lawn for at least 24 hours after applying a contact fungicide to prevent washing away the protective layer of the treatment from the leaves of grass. You can, however, water the lawn after spraying a systemic fungicide to aid in getting rid of lawn root rots.
8 - 3. 25 oz per 1,000 square feet. Using 1 oz per gallon of water would be fine if that gallon is only covering about 300-500 square feet. Typically 1 gallon of solution covers 1,000 square feet in a hand pump sprayer.
We recommend beginning lawn fungicide applications when nighttime low temperatures rise to 60°F. Typically, preventative applications are made at 14 to 30 day intervals, depending upon the fungicide. There are an abundance of lawn fungicides available that prevent brown patch and other lawn diseases.
Fungal control products should be applied once every other week, for three or more applications. This means you will have to re-apply the fungicide in 7 to 14 day intervals over the growing season. The reason for this is weathering and chemical breakdown. The rates and doses listed on the product must be followed.
Contributing factors: High humidity combined with hot temperatures during spring and fall favor the development of brown patch disease. Overfertilizing, overwatering, heavy thatch buildup, and mowing too short contribute to the disease.
All garden fungicides come with specific directions. Using too much is just as harmful as not using enough. Some people prefer to avoid the chemicals completely and opt for natural fungicides. Even when using a natural fungicide, you will still need to follow the directions carefully.
A general rule of thumb that is often used is that one-inch of rain removes about 50 percent of the protectant fungicide residue and over two inches or rain will remove most of the spray residue.
Both temperature and humidity can affect fungicide drift. The higher the temperature and lower the relative humidity, the greater the opportunity for fungicide evaporation or volatilization. This can be avoided by spraying early in the morning when temperatures are lower and the relative humidity is higher.
The procedure usually includes many different variables to make the turf look its finest year-round. A typical golf course has about 50 miles of irrigation piping. The sprinklers are spaced out every 20 to 30 feet, and there is typically one at the end of each row.
sprinklers are used to water grass on a golf course since they have comprehensive coverage and can cover large areas quickly. pipes bring in water from an offsite reservoir, which is filled by rain or other sources of natural precipitation such as lakes, streams, rivers, ponds, etc., to one point where it’s then pumped through valves ...
Suppose you see brown patches or dry spots on your golf course, more than likely, they aren’t watering enough. This is often the case if you notice a particular section of turf browning or drying out even when it has been watered. The problem here stems from inconsistent watering that either didn’t happen long enough to saturate soil down deep or happened for too short of time, so water ran off and left dry topsoil behind.
This is because golf courses use much water to maintain their greens, tee boxes, and fairways. However, how often they need to do this varies depending on the weather conditions in that area.
Greens are the most susceptible to high temperatures because of the low mowing height. With so little biomass the plant cannot sustain the heavy injury that turf at higher mowing heights can withstand. Syringing implies a light application of water to the green surface in its entirety.
Aeration holes allow excess moisture to evaporate and promote gas exchange in the soil, result ing in stronger root systems and turf that is better able to tolerate golfer traffic. The addition of sand, both firms and smooths the green surface allowing for consistent roll and speed.
The real difficulty associated with course maintenance is upholding standards well before a golfer comes to play.
When mowing your lawn you never want to cut more than the top 1/3 of leaf blade in a single mowing. This reduces the stress on the plant and ensures you won’t scalp uneven areas of your lawn. Following these steps should ensure premium year-round lawn conditions.”. --.
SPRING. “The first thing that comes to mind as far as seasonal maintenance is aeration. Aeration is performed in late spring and early fall. Core aeration involves physically removing small soil cores from the turf.
Most of the chemical applications have to be made in conjunction with rain fall events to ensure the chemical makes its way into the soil.”. “In the summer when temperatures spike above 80 degrees, all cool-season turf grasses (i.e. annual bluegrass, creeping bentgrass) are in danger of heat stress.
On the TifEagle greens, Brousseau uses a granular fertilizer two or three times a year. After the granular applications, he sprays the greens to maintain a constant, manageable growth. “Generally, we use a granular when we’re going into our aerification program,” he says.
Throughout the golf season, Corcoran applies foliar fertilizer, then granular fertilizer. He also uses organic fertilizer lightly in coordination with aerification and tries to go lightly with nitrogen, especially on the greens. “You have to get the right combination, not too light or heavy,” he says.
Among the 16 or so nutrients needed by plants like turfgrass, the most important three are nitrogen, phosphorous and potassium (NPK). Secondary elements such as calcium, sulfur and magnesium, as well as other trace elements, are needed for specific circumstances depending on climate and soil.
Though vegetation varies throughout the United States, green is synonymous with golf. Giving plants what they need to stay healthy and lush isn’t easy, and when it comes to turfgrass on golf courses, there’s a thin line to walk.
As we have learned, there are a wide variety of factors impacting how golf course superintendents are able to keep golf greens grass so short.#N#It starts with the construction of the green itself, the selection of the proper grass variety for the climate, appropriate maintenance and watering techniques, and hiring qualified mowers who can operate precision machinery for the right outcome.#N#The result is a smooth surface every golfer can love.#N#Perhaps you are interested in a job as a greenskeeper.#N#With a golf management degree from the College of Golf you can get started on a path to career you’ll love.

Up until the middle 1800s, putting greens were simply grass that was shorter due to sheep grazing there longer. Lawnmowers had not been invented yet. Greens were not specially built nor were they planted with specific grasses. They were selected because the spot was the right distance from the tee box, and the ground offered a natural shape that provided a reasonable surface for putting.#N#That all changed with the invention of the lawnmower. Then greenskeepers began to shape the putting green distinct from the surrounding area. They were contoured and graded in order to provide different challenges depending on where the hole was. Specific grasses were tested and used on putting greens due to their characteristics and suitability for growing at shorter heights.#N#Moving forward there are many factors that contribute to putting greens maintenance.
Today, science has advanced considerably in the construction of greens.#N#A modern green is really a large hydroponic system.#N#Construction starts with digging a hole the size of the green between 12 and 16 inches deep. #N#This hole is lined with a layer of plastic and then covered with gravel.#N#Drainage channels and sand are added.#N#Specialists then contour the surface to ensure rainwater runs off quickly and evenly, leaving no puddles behind.#N#All of this must be built in an area with lots of sunlight and free flow of air.#N#Once in the right grass seed is selected, the green needs lots of water and nutrients.#N#These days, greens keepers also use:#N#-Fungicides that keep diseases from overtaking the grass.#N#-Pesticides to prevent damage from invading insects.#N#-A number of different herbicides to kill weeds.#N#After the green has flourished, maintenance is key.#N#The green must be mowed every day with a special mower.#N#Workers must water and fertilize it constantly, adding the right mix of the above chemicals and aerating it on a regular basis.
Specific grasses were tested and used on putting greens due to their characteristics and suitability for growing at shorter heights. Moving forward there are many factors that contribute to putting greens maintenance.
These days, greens keepers also use: -Fungicides that keep diseases from overtaking the grass. -Pesticides to prevent damage from invading insects. -A number of different herbicides to kill weeds. After the green has flourished, maintenance is key. The green must be mowed every day with a special mower.
To keep the grass so short on greens, special mowers are used. Golf course mowers are reel mowers, not rotary like most lawn mowers used at home. The reel spins and cuts the grass like a tight scissor cut. The cut height is set by adjusting the difference between the front and rear rollers.
Some drained well while others did not. A variety of grass families ensured that no matter what type of soil was on a green, there would be a reasonable consistency of coverage. Also, grasses tend to grow at different speeds and at different times of the year.
This is typically done one to three times a year, depending on the course, the type of greens, and in what part of the country they are located. "The practice of core aeration is done when the grass is growing the most aggressively, so they can have the quickest recovery time," Moeller said.
That improves drainage and air exchange for the plants. It can take up to a couple of weeks for the greens to recover, but these procedures are critical for the long-term health of the greens.
Letting golfers know before they show up to the course should probably be the minimum practice, and most courses are trying to do that. How courses and clubs communicate this to golfers varies, of course.
Most golfers know the importance or aerating greens. Even if they don't understand why, they know it's necessary. Still, no one likes to putt on greens that have been recently aerated, especially a deep-tine aeration with core removal and top dressing. Trying to putt over holes is frustrating at best, and often golfers who do play in such ...
In order to consistently provide championship golf course conditions, the most important type of turf grass for courses to maintain is its greens. As expectations for putting surfaces continue to increase, technology has been helping the golf course maintenance team at Golden Ocala provide the best greens for our membership.
Moisture meters, which measure the volume of water content in the soil, are a regular part of our water maintenance routine on the greens to help us meet our desired results.
Following reading up to 100 spots on an individual green, our team applies water precisely with a hose to elevate the water level on each green based on the thresholds set by the superintendent team for the day. Hand watering greens is essential in providing consistent tournament-quality putting surfaces.
The superintendent can apply a small amount of water to help remove the frost if the air temperature is not too cold. Running fans to blow air over the greens (the same fans used in the summer) will help to reduce frost problems if the temperature is only a few degrees below freezing. Greens with shade in the morning have lower soil temperatures ...
Play is often delayed on courses during the winter due to frost on golf greens. The reason the club should not allow play on greens that are covered with frost is that the turf will be damaged from walking on the frost. The ice crystals in the frost can puncture the leaves from foot pressure.
The thawed layer will be saturated with water and becomes spongy. Walking on turf with this condition will cause foot printing and can cause the surface of the green to become uneven. Severe turf damage can result from shearing off the roots as the turf moves above the frozen layer.
Golfers are eager to return to the course on the nice days following long periods of cold weather. All greens usually do not thaw at the same time. Shaded greens are the last to thaw and more damage often occurs on these greens because it is difficult to keep golfers off the course any longer.
It is difficult to explain to golfers that they should not play on greens that are thawing during a warm and sunny day following very cold weather.
