1.877.4.HAR-TRU (1.877.442.7878)
Wild Weather! Managing the Extremes On the east coast, this has been one of the coolest and wettest springs we have seen in some time. We had snow on the ground through March in many locations. Where there wasn’t snow there was rain, oh so much rain! And at this writing the first named storm of the season is tracking up the east coast delivering copious quantities of…rain! It’s difficult not to complain but out west any grumbling would fall on deaf ears. They are already battling the dry conditions with fire outbreaks from New Mexico to Northern CA. West Texas experienced some relief but is still reeling from years of drought. Last year was Colorado’s worst year for fires and there is talk that if these patterns continue there could be a return to conditions similar to the Dust Bowl era. We don’t claim to be smart enough to know to what extent these conditions are being fueled by global warming or represent natural fluctuations, but we do know they can make life difficult when it comes to managing your Har-Tru courts. In this article we
will look at strategies for keeping courts performing optimally despite the extremes. The Role of Water Before getting into strategies it’s important to have an understanding of the role water plays in a HarTru court. Simply put, water is the glue that holds the court together. It’s critical for both stability and compaction. Play on a court with too little or no water and it will soon become dry and dusty. Without change, it will eventually become an unplayable sandbox. Water washes the finer sized Har-Tru particles (the fines) into the void spaces between larger sized particles to get the surface to mesh together. This is what provides the stability. Water also acts as a lubricant allowing the particles, when manually compacted with a court roller, to get closer together and form a tighter, firmer surface. While the presence of water is important, an overabundance is detrimental. Too much water
will actually float particles causing them to separate, effectively loosening the court and decreasing stability. If you have ever stepped on a soggy court after a long soaking rain and had your foot leave an impression you know what I am talking about. The good news is that Har-Tru courts are constructed so as to retain an optimal amount of water. They have base layers that act as
reservoirs and can hold water, which is very useful when there is an excess or deficiency. Additionally, courts are built with a very subtle slope – 1” every 24-30’ – that facilitates the absorption and the shedding of water depending on conditions. Since the extremes involve the absence or oversupply of water, this foundation sets the stage for discussing maintenance strategies.
LUTE/SCARIFIER SCR04 - 30” SCR05 - 48” The lute/scarifier is two tools in one – made of all-aluminum for scarifying, leveling and removing loose granules. It is strong and sturdy, yet light enough to use all day and excellent for spreading new material during top-dressing. The concave shape of the 30”wide blade allows the tool to “float” along the surface, without grabbing or digging in. Also available in 48” width.

VERY WET CONDITIONS
Y
ou can learn a lot about your courts in very wet conditions:
Drainage – How well do your courts drain? Down time after rain is a strong indication but the best way to ascertain what happens as water hits your courts is to watch it as it happens, so grab your umbrella and see what you can observe. 1. Does water work its way across your court in a consistent direction? It should. If you have one area that has no standing water while another has a huge puddle your courts may need to be re-graded. 2. Are your courts dammed at the low end? If so clearing space for water to drain will significantly improve the
way your court responds after a rain, reduce risk of algae, moss and weed growth and improve playing conditions. 3. Pesky puddles persisting in the high play areas? Shut the courts down for 24 hours and apply a patch with new material. You will need a Lute Scarifier (pg. 2), a Hand Roller (pg. 2), and a long straight edge for leveling, such as that found on the 7’Drag Brush/ Lute (pg. 6). Be sure to have it well compacted before letting players back on. In the interim, use a Super Sopper (pg. 5) to get these areas dry right away. When dry, scarify the bottom of these low areas using a Lute Scarifier (pg. 2) or 24” Hand Gator Rake (pg. 7) to break through any accumulation

rest of the court. This makes them susceptible to all kinds of growth, and what starts at the edges of the court can creep into the playing areas. This work should be done once every couple of weeks using a hand roller (pg. 2) and a 24” Gator Rake (pg. 7) or Lute Scarifier (pg. 2). Don’t forget the net line! Use a bungee cord to hold the net up while you work this area as well.
Court Surface – You can’t please everyone when it comes to the court surface so we recommend trying to keep the court playing as consistently as possibly. 1. We are often asked how firm, fast, or hard a HarTru court should be and it’s a difficult question to answer as player preference varies considerably. What’s important is to understand what compaction can do for you and when to roll. A firmer court takes on less water when it’s very rainy – that is more runs off and less gets absorbed. This is often why some courts dry faster than others, even in the same facility. If one court get a lot of use, or is an older more seasoned court, it will typically be firmer and shed more effectively, assuming no low end blockage. In summary, using a tennis court roller (pg. 2) with greater frequency can help you in times of excess rain. It’s best to roll after a rain and will tighten up the court and re-compact some of the loose sliding material. 2. Brushing helps dry out a tennis court. It’s the equivalent of turning over wet leaves and allowing the sun and air to hit them. Using a drag brush turns over wet material and allows it to dry, as well as the surface below. The more aggressive the drag brush the more material it turns over so a stiff bristle drag brush (pg. 6) or a steel bristle drag brush (pg. 6) will be more effective than a fine one. One word of caution though is that in these conditions, these more aggressive brushes tend to clump up more of the loose wet surface material and may need to be cleaned off during use. We also suggest Gator Rakes (pg. 7) with staggered tines as this tool is very effective at agitating without clumping and may be a good alternative. Regardless of what you use, sweeping often and in multiple directions helps courts dry. 3. Keep the edges of the court rolled and scarified. These low play areas will always be softer than the
4. Wet conditions provide a ripe environment for the growth of moss, weeds and algae. Most of the time regular court maintenance is adequate for keeping growth at bay but in extremely wet conditions it’s not uncommon for things to start growing even in the playing areas, particularly if your courts drain poorly. Growth control options include RoundUp (pg. 8) for broad leaf weeds and grasses, Moss Buster (pg. 8) for moss and copper sulfate products for algae. Be sure to check for and abide by all local environmental regulations when it comes to the application of anything to your tennis court. Irrigation – It may seem obvious to most to turn off the irrigation system in wet conditions but it is not uncommon see the sprinklers running automatically in the middle of a rain storm. And what if you have a HydroCourt? Will shutting off the system promote faster drying? 1. If you have an irrigation system that operates on a timer, install a rain sensor. These sensors cut the system off and keep it from running in the event of rain but allow the system to run if the rain is minimal. 2. If you have a HydroCourt, open the drains and allow water to exit the court. This will help handle the oversaturation conditions. Note that this is only recommended for consistent rain over an extended period. For the average rainy day or when having a daily thunderstorm it is best to leave the system on. A HydroCourt, since it already has an optimal amount of water in it, will do an excellent job of shedding excess.

SPLIT-ROLL HAND-TOW ROLLER ROLHAN24 This 24” x 24” hand roller is improved to give the same split- roller action as our more expensive rollers. Dual drums can be water filled for added weight, yet can turn on the court without damaging the surface. This is the only hand roller that can be towed in ovals with its dual-purpose handle. A scraper brush is included for removing any build-up on the drum. Good roller for those on a tight budget. 1 year warranty.
SUPER SOPPER DRY04 - 7 gal. Mackerel DRY05 - 14 gal. Dolphin The Super Sopper takes care of total water removal by lifting water off the court using an ingenious collection system that holds up to 14 gallons at a time. How does the Super Sopper work? Water is lifted from a court using a sponge-covered barrel and is strained into the center of the porous barrel where it can be held and later emptied. The Super Sopper is perfect for courts that tend to puddle in low areas and need total water removal to get courts in play fast. It can be used on both hard courts and Har-Tru courts. Replacement sponges available. DRY04SP - Mackerel Replacement Sponge DRY05SP - Dolphin Replacement Sponge

If you water with a sprinkler system it’s critical to provide the court with enough water to stay in good shape until the next watering cycle.

D
ry courts not only make the playing conditions slippery with bad bounces and dust blowing in your face, they make the court highly susceptible to erosion, and this can result in long term damage. Court Surface 1. A well rolled, compacted court retains water better than a loose one. Make the pores between stone particles smaller and it’s harder for water to escape, slowing evaporation and improving moisture retention. 2. Since brushing dries the court out, use an Aussie Clean Sweep (pg. 8) rather than a drag brush, and stay away from aggressive brushes. The Aussie grooms while disturbing a minimum of surface.
This will reduce water lost to evaporation. 3. Use magnesium or calcium chloride (pg. 10) on your courts. These two products attract water and when applied to a court will draw moisture out of the air and help the court retain any moisture that’s in it. It comes in 50 LB bags and a recommended application is to use 100 LBS per court per week during extremely dry periods. Some use it all summer long, particularly before tournaments or special events. Its best to apply it in the evening so its watered in over night. Irrigation 1. Sub-surface irrigated courts are much

more effective at keeping courts wet than any above ground system. Nearly 75% of all new courts installed go with the HydroCourt system for that very reason. Water usage is reduced by 40-50% and coverage is extremely consistent. 2. If you already have a sub-surface irrigated court, raise the water levels at the first sign of drying. Evaporation rates will be much higher when it’s extremely dry so you may need to do this several times. Raise water levels gradually in ¼” increments until dry spots disappear. 3. If you have above ground irrigation water more frequently for shorter durations. This is the best way to allow water to fill the reservoir that is the
base of the court. Application of large amounts of water at one time causes water to run off rather than being absorbed. It’s particularly important over night to space out watering cycles and have as many as possible without leaving the court too wet for morning play. 4. If coverage remains an issue on your above ground irrigated courts it may be time to install new sprinkler heads (pg. 11) and/or new valves (pg. 11) that can provide better coverage. Our Consulting Services (pgs. 12 & 13) department can assess your system for you and help you design a new one. Getting even coverage makes an incredible difference when battling dry conditions.
