5 Tips for Choosing a Fertilizer

Posted by Mary Martinez on Jun 30, 2017 8:38:59 AM

Does the brand of fertilizer you use really matter? Short answer is yes, it does. There is a lot more than just N-P-K that makes up a bag of fertilizer. There are a few important things you should look for when selecting a brand of fertilizer.

EEF (Enhanced Efficiency Fertilizer)

The Association of American Plant Food Control Officials (AAPFCO) defines EEFs as products with characteristics that allow increased plant uptake and therefore reduce potential nutrient losses to the environment (e.g., gaseous losses, leaching, or runoff) when compared to an appropriate reference fertilizer that does not contain additives. Controlled or slow-release fertilizer provide solutions that contribute to environmental responsibility:

  • Reducing N volatilization and slowing the conversion to nitrate means more N remains available to plants
  • With gradual metering of N, uptake by the plant is optimized; less is underutilized, reducing potential loss to the environment
  • The result is more efficient nutrient use, meaning your customers can apply less N, which not only benefits the environment; it helps to preserve this vital resource as well

TurfGro fertilizers have several slow release fertilizer options that include technology such as Duration and XCU.


Micronutrients are essential for soil health and plant growth. Soil analysis shows micronutrient deficiency is common in soil and can be a contributing factor to pest problems and slow germination. If a fertilizer contains one of the common micronutrients (boron, copper, iron, manganese, zinc, magnesium, calcium & sulfur) they will be listed on the label after NPK.    

What makes TurfGro fertilizer different from other brands is that it is manufactured and blended locally in market. This allows us to design the formulation to meet the soil needs of that market, adding micronutrients commonly missing.

What’s in the Bag?

Typical fertilizer is made up of four components: urea, nitrogen, potash and filler. The first three components provide nutrients to the turf, while “filler” normally doesn’t offer any value. The amount and content of that filler can influence the quality of that turf.

Amount – the more urea, nitrogen and potash in the blend, they less need for filler. So when you select a fertilizer with a higher NPK, you will have less filler in the bag. In addition to NPK, micronutrients like calcium and magnesium reduce the amount of filler blended in the fertilizer.

Content – most higher end fertilizer will use biosolids or other organic-based product as filler. Most less expensive products use limestone, which provides zero nutrition to the soil. It’s less expensive, but you are still paying for product that can’t be used by the turf.

When needed, Horizon’s TurfGro fertilizer commonly use biosolids as the basis for filler, ensuring a higher value product for you.


Pellet Size

In blended fertilizers, the individual particles remain separate in the mixture, and there is a potential for segregation of the nutrients. This problem can be reduced by using materials that are the same size. Properly made blends are generally equal in effectiveness to other compound fertilizers.


You can always find a cheaper bag of fertilizer. But when you look overall cost of the application you will find that a cheaper bag will normally cost you more in the long run. Following a program and using a premium fertilizer like TurfGro will help you deliver healthy, green turf to your client season after season.

LED LAMPS – You get what you pay for!

Posted by Mary Martinez on Apr 21, 2017 8:00:00 AM

Yep. There are a lot of LED lamps available online today. And while those lamps are often available at a significant discount, there can be a substantial difference in quality. Horizon only sells products from quality lighting manufacturer partners (Vista, Unique, FX, Kichler & Brilliance) that make professional-grade, reliable products. There is a difference! See for yourself…


  1. Distributor Support – no matter where you buy, product quality and warranty issues can arise. When there is an issue with products bought online, there is often only an email address provided for you to use when seeking support. Great. But wouldn’t you prefer a living, breathing human being that is available to assist with everything, from troubleshooting to returns?
  2. Warranty & Longevity – Quality lighting manufacturers stand behind their warranty. So, the expectations behind a 5 year warranty and 35,000 hour life are real and supported. Cheap LED’s will commonly state they last for 20 years, but on the back of the box it will say “when run 3 hours a day”. Some even say not to run more than 5 hours at a time or they’ll burn out prematurely.  
  3. LED Binning – LED’s are grown more than created. As a result, their color temperatures (2700 Kelvin, 3000 Kelvin, etc.) are all over the board, so they must be sorted. This process is called binning, and it’s expensive. Quality manufacturers bin their LED’s, and as a result give consistent color temperatures. So 2700K is 2700K. Cheap online LED’s save money by skipping the binning process, and the result is an unprofessional, inconsistent color temperature, where 2700K can be +/- 500K. 
  4. Inconsistent Light Output (Lumens) – Quality manufacturers utilize photo-spectrometers to measure the output of their lamps. This is another quality control step that cheap LED manufacturers skip, which leads to inconsistent output across the lighting system, causing Mrs. Smith to ask why one light hits the top of her trees and the other doesn’t.
  5. Thermal Management (Heat Sink) – In order to generate a lot of light at a very low power consumption rate, LED’s “burn” very hot. This generated heat has to be managed, or dissipated, properly. Horizon’s professional quality LED lamps have this heat sink built in. Most cheap LED manufacturers provide sub-standard heat sinks, which can lead to premature failure and even fire.  
  6. Indoor/Outdoor/Enclosed Fixture Rated – The LED lamps sold at Horizon are designed and manufactured to be used outdoors in an enclosed fixture. Most of the lamps available online come in packaging that clearly states they are not intended to be used outdoors, or in an enclosed fixture. Using these lamps can lead to premature failure, and other issues.
  7. UL, CUL or ETL Listing – all of the LED’s lamps that Horizon sells are rated by one of these entities, which all uphold the same level of standards. Many online LED lamps are not rated/listed, and therefore are manufactured without having to adhere to any standards. This really should speak for itself; the standards are there for a reason.
  8. FCC Listing – All Horizon-sold LED lamps are FCC listed. Most online LED lamps don’t carry FCC clearance. Electronic products that aren’t FCC compliant can cause many kinds of issues, from opening a neighbor’s garage door or messing with Aunt Harriet’s pacemaker.
  9. Rated 8-15 or 8-25 volts – Horizon’s LED lamps are rated to operate consistently across a wide voltage range and maintain a constant light output across the range. Most cheap LED’s are not manufactured to meet these ranges, resulting in small voltage spikes that can cause early lamp failure and varying light output.


In our business relationships are important. You can rely on your relationship with Horizon to support you and your business every step of the way. Why risk your relationship with your client by installing inferior products to save a few bucks? Want to know more? Stop by your local Horizon store today.

Backpack Sprayers - internal piston or diaphragm pump?

Posted by Mary Martinez on Jan 30, 2017 4:54:12 PM

If you are reading this blog, you've probably always used a diagraphm pump backpack sprayer and are ready to disagree with everything in this article.  We get it!   You've grown to like the blue stains on the back of your shirt. 

But if you are interested in breaking some myths about backpack sprayers, then read on.  And while diaphragm units are a great option, we've got some compelling reasons to consider an internal piston pump unit instead.


Five Arguments for the Internal Piston Pump

1. Leaks

Well this one is pretty straight forward - the pump is INSIDE the tank and won't leak on your backside.  Diaphragm pumps are prone to leakage and lead to "blue butt".

2.  Agitator

Internal piston pumps have an agitator below the piston chamber so powdered chemicals like Roundup QuikPro are constantly mixed.  Most diaphragm pumps don't have an agitator so chemicals can settle out.

3.  Clogs

This is probably the biggest myth about internal piston pumps - they clog when using powdered chemicals.  The truth is piston pumps can clog if the unit has NO agitator, or if agitator is located ABOVE the piston chamber. A piston unit with an agitator BELOW the chamber will NOT clog when using Roundup QuikPro. 

4. Pressure

Internal piston pumps have more power, so they can spray at higher pressure and reach further distances. 

5.  Costs

At Horizon our internal piston pumps are offered at a lower cost than the diaphrgam pump so you can get a better unit at a better value. 

Bottom Line:

If you’re ready to ditch the blue butt and give the Internal Piston Pump a try, drop by your local Horizon store and check out our complete selection of Jacto & Field King professional backpack sprayers.

Tricks and Tips to Applying Post-Emergent Herbicides

Posted by Mary Martinez on Sep 22, 2016 8:00:00 AM

Applying post-emergent herbicides in the fall is an important step in controlling difficult perennial weeds that would otherwise reemerge in the spring. While using a pre-emergent herbicide is very effective in preventing new annual weeds, which is also an important weed control measure for those weeds which reproduce mainly by seed, it will not take care of those weeds with spreading roots. In other words, effective weed control is a two-pronged approach, and there are some reasons to focus on post-emergent applications in the fall.

Timing is Everything

In order to effectively control perennial weeds, it is important to understand their life cycle. While spring applications of post-emergent herbicides have the advantage of taking out weeds before they have a chance to build up a thick, waxy surface that is difficult to penetrate, the down side is that the herbicide is not always carried down to the roots, so the weeds can regrow. In the fall on the other hand, the weeds are carrying their own sugars down to their roots for winter storage, so a post-emergent herbicide application will be carried right down to the root with the sugars – killing the weed for good.

Let it Rest

Avoid mowing the turf for two to three days before and after applying a post-emergent herbicide.  Because the herbicide is absorbed through the blades of the weed, having longer, bigger leaves (more surface area) is essential to success.  If you mow too quickly after application, you risk removing the herbicide before it can reach the roots.  Turn irrigation off, and do your best to minimize disturbances to the turf so that the product can be absorbed in a consistent manner.

Not too Hot, Not too Cold

The ideal temperature for applying post-emergent herbicides is between 60 and 85 degrees - when most weeds are actively growing.  Too cold and the plant goes dormant and cannot move the chemical to its roots.  Too hot and you risk volatization of the herbicide in high heat.

Liquid or Granular?

In general, liquid products tend to be more effective than granular.  The liquid formulation absorbs into the leaf tissue and moves through the plant more quickly than granular.  Plus they are normally rain-fast in 3-6 hours.  But a “weed and feed” granular product is convenient and efficient, eliminating the need for a second application and reducing labor costs.  If you choose a granular product, apply in the morning when turf is damp so the product will stick, and avoid irrigation and disturbances for at least 24 hours after application. 

Remember, post-emergent herbicides can cause considerable damage to the desirable turf and plants on the property, so be sure to read the label before applying. Also, take every precaution to minimize drift or runoff. 

Your local Horizon store has an extensive selection of herbicides in a variety of sizes including pints, quarts, gallons and 2.5 gallons.  To learn more, contact your local Horizon store.

How to Select the Right Lawn Spreader

Posted by Mary Martinez on Sep 19, 2016 11:11:21 AM

Selecting the right spreader for a fertilizer or seed application isn’t that complicated.  But avoiding some common misperceptions can help ensure you get the right machine for the job. 


How big of a hopper do you need?  This is one of the most common misunderstandings when buying a lawn spreader.  50-pound hopper for a 50-pound bag of fertilizer, right?  Wrong!  50-pound spreaders have a high risk of spill since a full bag of product goes right to the top.  They are light-duty units definitely not fit for the landscaper who uses them on a regular basis. 100-pound spreaders on the other hand, are difficult to push when full at a consistent pace necessary to achieve uniform results. A 70-pound spreader is the ideal size when using 50-pound bags.  Not only do you avoid spillage, but you can refill product before it gets all the way to the bottom.


Most commercial lawn spreaders come in either stainless steel or epoxy powder coated plastic.  The biggest concern for landscape professionals regarding spreaders is rust on the frame, caused by failures to wash off abrasive materials and store inside away from the elements.  And while more expensive, the stainless steel spreader will withstand rust better than other material, which means it will last longer and give you a better return on investment.  Durable pneumatic tires are also important; lower quality tires can create a choppy ride and ultimately an uneven application.

Product Waste

Having a quality spreader with multiple attachments will can help you better manage how much product goes out on each application, lowering your cost of goods and improving profitability.  Side-deflectors deliver a targeted, accurate spread and prevent material from landing on sidewalks, driveways and streets.  This eliminates product waste and ultimately saves you money. Another helpful attachment is a hopper cover, which protects material from rain or snow during application and reduces the risk of a spill.

Don’t Forget to Calibrate!

Calibrating your spreader for every application is the only way to ensure you are applying fertilizer and pesticides at the correct rate, also reducing your overall cost of goods.  If you do not calibrate you risk applying too much or too little product, risking serious injury to your turf or disappointing results.  Calibrating your spreader is easy to do and normally takes about 5 minutes.  To learn more on calibrating your fertilizer, watch our “how to” video here.

Smart Water Nozzles Can Help You Conserve Your Way to Profit!

Posted by Mary Martinez on Feb 12, 2013 11:10:00 AM

Millions of irrigation systems in use across the county are designed to keep turf and plants green and healthy, but aren’t designed to conserve water.

Smart water nozzles work to conserve water by managing flow through irrigation systems and applying water more efficiently than traditional nozzles. Replacing old nozzles with smart water nozzles is an excellent, environmentally responsible upgrade to any irrigation system.

“Smart water controllers are great; they monitor elements like rain, wind and temperature but they can’t make up for uneven water distribution,” said Dan Puthuff, construction channel manager, Horizon Distributors. “Smart water nozzles take water conservation to the next level by ensuring that water is applied evenly and uniformly across a landscaped area.”

Horizon Distributors offers a full selection of smart water nozzles including:

  • Toro® Precision™ Series Spray Nozzles

Precision Series Spray Nozzles deliver water at a precipitation rate of one inch per hour, ensuring that water is applied more slowly and evenly without sacrificing landscape health.
