When To Water & For How Long?

When should I water my lawn and for how long?

Regardless of whether you live in the country or the city, the best time to water your lawn is in the early morning. This is the time of day when your lawn will absorb the most H2O and you will lose the lease H2O to evaporation. However, one bonus to watering in the early morning for city dwellers is that the water pressure will be at it’s peak before the population of you city gets up and starts using up all that water pressure for showers and baths! For rural folks, whose water comes from a well or direct from a lake, or pond or other source through an onsite pump.

Avoid watering during the day time, especially when the sun is at it’s brightest. Only a fraction of that precious water will actually make it to the grass.

How much should I water my lawn?

The amount you must water your lawn is largely impacted by the amount of rainfall you get where you live. This will be driven by the weather and a phenomenon called evapotranspiration (i.e. “ET”.) ET is the combined effect of water used by the plant and that which is lost to evaporation. ET is expressed in inches (or mm) of water per week. So based on the amount of water your grass takes in for nutrition and the amount of water that the environment takes out of the soil, you will have a new amount of water that has been debited due to ET and must subsequently be replaced.  Often times a local university will have accurate ET rates for your area of the country. You may also be able to find these rates published regularly in the newspaper or on a website.

How deep into the soil should water penetrate?

Soil-depthGenerally speaking, water should be able to penetrate down 6-inches into the “root zone” of the lawn. Ideally it is time to water again when that water level is at about 3-inches. You can check this in a variety of ways, by using different tools such as a shovel, a soil sample puller, or a digital sensor.

How much is too much (or too little?)

Most people are surprised to discover that there is more damage done, by overwatering a lawn than by under-watering it. This is due largely in part to the plant structures inability to extract the water left in the soil once so much water has washed through it. Without the water to provide it nourishment the grass becomes susceptible to insect problems, physical damage and disease.

What happens to grass during a drought?

ng655_01_front TurfSpyGuideIf your lawn can’t get enough water it will first go into a dormant stage, often marked by a bluish color. If the drought continues until the soil water is fully used, death will result for most cool-season grasses. Bermudas and other warm-season grasses will probably recover, however, the lawn’s quality will not.

The Fast & Easy Way To Fix a Broken Sprinkler Valve

Every so often often, just when you think that everything in your sprinkler system is working just perfect, something will go wrong. Either you will wake up to discover that magically somehow one of your sprinkler has turned itself from a sprinkler into a geyser! or a new pool exists where yesterday you had a valve box. Such is life. We fix them and move on. No need to stress.

I got a phone call the other night from my youngest brother who still lives at home. Since i moved away from home and since my middle brother moved away he has been charged with the task of maintaining the family sprinkler system and yard. (This doesn’t sound like it would be that big of a task or responsibility, however it is a HUGE responsibility because back when we installed the sprinkler system we didn’t have the good sense to look online for help installing the system. We simply relied on the advice we got from the workers at the local sprinkler supply store and/or the local big-box hardware store. And while the concept of installing a sprinkler system yourself seems quite simple, without the correct advice and instructions it is easy to make mistakes that you will regret for years to come(…like putting too many heads on a zone, or spacing sprinkler too far apart!) In hindsight, I wish with all my heart that we would have looked online and found “Sprinkler School” because it would have given us 100% of the information and instruction that we needed to have installed a proper and functionally sound sprinkler system.

So, for years now we have lived with the monster that we created. We need (desperately) to start over and install a new system from scratch (the RIGHT way) but till that day comes, we will continue to keep fixing and adjusting and tweaking our Frankenstein system!

My brother had called be from his cell phone as he was standing out in the yard. He explained to me that there was something wrong with one of the valves and that it was not working. He wanted to know if I could tell him how to fix it or give him some ideas about what was causing the problem. Unfortunately my troubleshooting superpowers are severely diminished because he is in Idaho and I am in Texas. Something about that kind of distance impedes and messes with my ability to figure out what is making things not work and why.

The good news is that there is a shortcut for fixing valves that makes the repair so easy that even your mom could do it if she had to! (Just kidding, if your mom is anything like mine, she can could solve world hunger, end war, fix the cars bad alternator and have dinner made for the family all before 6pm!) Nevertheless, the process to fix a broken valve is really really easy, and basically anyone who can read this can fix one themselves.

So I told him that I would send him a new valve from our online store if he thought he could get by for a day or two till the part could get to him. Here are the direction I sent him. You can follow these steps to fix your own valve once you have a new replacement handy and ready to install.




  1. Shut off the water to the valve manifold or the area where you are working and remove standing water if possible. valve-repair-1
  2. Unscrew the solenoid and set it aside (be sure to keep it clean and out of any dirt or mud)valve-repair-2
  3. Unscrew top of your valve (or unbolt the top) and remove it. Set it aside on a towel or a clean surface. Following the same procedure, open the top of the replacement valve you purchased valve-repair-3
  4. Remove the internal parts from the defective valve, paying attention to the order and placement of the pieces. Discard the old pieces. valve-repair-5
  5. Replace the discarded pieces with those from the new valve. (you may choose to use the new top from the replacement valve or continue to use the original) Pay attention to the alignment holes! valve-repair-4
  6. Ensure the solenoid is wired correctly and  matches the wiring of the other valves in the box (be sure to use grease or silicone filled wire nutsvalve-repair-6
  7. Using the sprinkler controller activate the zone that corresponds with the valve you just repaired to confirm the repair was successful.

Most people are are surprised to find out that this repair is a recommended way of repairing a valve. The housing for valves are extremely durable and will continue to function as if it were a new valve for the life of the product or until it cracks or otherwise physically broken. The bonus for this type of repair is that you will have a spare solenoid on hand for future use in the event that you need one down the road!

6 Ways to prevent water waste

9 Ways to prevent water waste


Everywhere you look the world is (trying) to “go green”. This is especially true for the irrigation industry — finding ways to water our yards, gardens and crops that cuts back as far as possible on the senseless loss or overuse of water is key. Here are 9 ideas that can be easily implemented in your own yard.


night-sprinklerWater at night: By watering at night, more water is able to get to the roots of the plant than if you were to water during the day time because the sun and its heat are not causing the water to evaporate.

Mulching your grass clippings:  Instead of bagging your lawns clippings, it can be beneficial to mulch the clippings and let them settle back into the turf. The clippings will create a mat or thatch of sorts which traps the moisture in and protects from too much direct sunlight. Most recent lawnmowers have a mulch setting, or a removable bag which causes the mower to mulch by default.  Additionally, special blade(s) can be purchased for your mowers which are designed to mulch the clippings while they are inside the mower by adding an airfoil and additional sharp up-turned blades to further mulch the grass as it tumbles around under the mower before falling down into the turf.


MowerMow it high: Keep the deck setting of your lawn mower up above the 3.5” setting. The taller grass will allow a shadow to be cast from the turf and prevent water from evaporating too quickly. Additionally, taller grass looks healthier and helps to hide stressed areas.


2014-06-04_13-54-09Geyser Stop: With the help of this little device, you will never have to worry about waking up to a H2O geyser in your front yard or outside your business. Simply install one of these inexpensive devices inline with each sprinkler head you have and it will mechanically monitor and regulate the flow of water. Should the sprinkler head break or become damaged and begin to gush water out in a geyser the metal ball that is housed within the valve will be forced up against a seal preventing any water from flowing through that head. All other heads will be able to continue watering as usual.


aaa-smartSmart Controller: The new generation of smart controllers is making big waves in the sprinkler industry. Suddenly, managing the start and stop times of your sprinklers is easy to do! You can use your laptop or smart-phone to create watering schedules and programs and schedule them in a calendar to start and stop at predetermined times. Because sprinkler controllers can be difficult to program, many people took a “set it and forget it” approach to watering. Letting the sprinkler system run for the same amount of time all year long, instead of giving the lawn the prescribed amount of water according to the season. A smart controller will empower you to make those changes without the fear of messing something up and having to call someone to reprogram the controller.


shutterstock_79739230Rain Sensor / Moisture Sensor: Without a rain sensor or a smart controller that is connected to a live weather feed, your sprinkler system won’t know the difference between a sunny day and a downpour. Incorporating a rain sensor will prevent watering during a rainfall. Some rain sensors can even meter the quantity of rain and calculate how much system run-time was replaced by the rainfall and stop the system from running accordingly. Similarly, a soil moisture sensor is able to override the watering schedule when necessary.


Installing Check Valves: Check valves are designed to prevent from needlessly draining out of sprinkler heads at lower elevations in the system whenever the system is turned off.  This problem is especially prominent in conditions where there are elevation changes and hills where water can run back down from and out of sprinkler heads at lower elevations. Look for sprinklers with build in check-valves in them. Sprinkler heads that include a check valve in them will prevent any water from escaping in low pressure situation and are often indicated as “SAM” (Seal-a-matic) or “CV” (Check Valve) in the model number or name of the product.


Water Meter connected to smart controller:  Most controllers will accept a water mete to be installed for ministering the amount of water being used. When paired with a smart controller that is connected to a wifi network. The smart controller will monitor the amount of water that is used on average and if water begins to be used at a higher rate than what it has come to recognize as “normal” it will send out a warning message over the network to let you know that there is a problem of some kind.


165376220_fb050b94da_z_0Stay in adjustment: Check your sprinklers regularly to ensure they are not spraying places that they shouldn’t be. Common offenders of misplaced water waste are sprinklers spraying on sidewalks, the road, sides of buildings or fences, or vegetation which is blocking the water from spraying where it needs to go.
