CHEAT CODE™ was created with one aim in mind… to be the best performing perennial ryegrass blend available for fertilized lawns in the East… from #1 best turf quality averaged among all fertilized NTEP locations in the east to the best gray leaf spot resistance to the best traffic & wear performance and even the best self repair and best 5-year poa annua performance of any blend on the market (besides PODIUM… our other rye blend), we think CHEAT CODE™ is a no brainer for anyone planning to plant rye in the east that has average January lows of 14° or higher.

CHEAT CODE™ had the 2nd best color of any blend for eastern locations but the blend that got first for color got last place in almost every other metric and often last place by a wide margin, so, 2nd for color might as well be first (see gray leaf spot rating or 5-year poa annua below as a few examples).

NTEP performance below is based on per seed cultivar averages (since the actual blends weren’t tested on NTEP) and data is from the 2017-2021 Final Report.

NOTES:

CHEAT CODE™ is simply PODIUM™ spiked with 40% Slugger 3GL – which is our favorite cultivar for the Northeast!  Slugger 3GL boasts a gray leaf spot rating of 8.7 out of 9.0 (tied for 2nd out of 114 cultivars tested) and it topped the regional averaging for the highest and most consistent turf quality of any confirmed available ryegrass cultivar.  Slugger 3GL also holds the line with top 10% fertilized location color (and top 8% color specific to fertilized locations in the east) and has nice secondary traits like drought performance (top 8% in Utah drought testing), elite traffic & wear, very low 5-year poa annua (less 5-year poa than any of our competitor's blends)… 5-year poa annua performance is an inference into how competitive a grass is for a given area and poa annua invasion was tested in Adelphia, NJ.

 

Rye & Disease (very far into the transition zone is not recommended even for the best rye)

*** Note: ryegrass does not do well with snow mold (especially our rye blends) so preventative fungicide could be a good idea in some areas ***

*** Note: ryegrass is more prone to pythium than other grass families so having preventitive/curative fungicide on hand of chemistries known to be effective against pythium is highly recommended as a caveat to planting rye in an area with high disease pressure and water should be applied no more than every 3 days during drought.  Pythium pressure is highest when moisture is excessive and night lows exceed 65-70°F.  Excess nitrogen is also a risk factor so dialing down the nitrogen a little can be a good idea from June-August.

*** Dollar spot or red thread/pink patch are a sign of low growth which most commonly means not enough nitrogen but occasionally low sulfur, low water, low phos, low light, etc. are the cause of the low growth.

 

CHEAT CODE™ NOMINAL CULTIVAR RATIO
≈ 40% Slugger 3GL Perennial Ryegrass

≈ 20% Mystique Perennial Ryegrass

≈ 20% SR4750 Perennial Ryegrass

≈ 20% Zoom 2 Perennial Ryegrass

*** Approximately 0.5-1.0% annual ryegrass is common in perennial rye.  We recommend not to go too long between mowing during seed head stage for the first year to halt the life cycle of annual ryegrass.

Common overseeding seed rate:  4-5 pounds per 1,000' (175-220 lbs / acre)

Common bare dirt seed rate: 7-9 pounds per 1,000' (300-400 lbs / acre)

Caution: More seed is not necessarily better than less seed.  Lower seed rates may improve color and reduce disease pressure, so in areas with higher disease pressure the lower end of the recommended seed rate may outperform higher seeding rates.  For bare spots, very light spot seeding is recommended rather than overseeding when possible to reduce crowding in already dense areas.

 

TIPS FOR SUCCESS

  • Seed germination basics:
    • Bare dirt is ideal (or at least no thatch)
    • Adhere to proper seed rate... too little seed means increased weed pressure and increased erosion risk, and too much seed can mean lesser color and increased risk of disease.
    • Rake seed in w/ a Groundskeeper II rake (or slit seed if you can on a low setting)... grass seed sitting on the surface will be unlikely to germinate
    • Keep soil moist and never dry or soaked until germination... perennial ryegrass doesn't need as much water during germination to germinate... I physically touch the dirt prior to watering most of the time... often soil is already moist and more hours can pass before water is needed.  Watering just once per day is typically enough for perennial ryegrass to germinate well as long as some water is getting into the soil profile (at least 60% of reference evapotranspiration
    • Water for enough days to germinate your slowest germinating seed.
    • A germination rate of 50% starts around 50° soil temps for most cultivars... seeding before soil is warm enough may reduce germination.  I like to aim for 50-55° soil temps for spring seeding (slow germination but better summer hardiness) or let soil dip to about 60-65° for fall seeding (or when regular light rain is expected).  It's important not to seed too late for fall seedings especially on bare dirt because if soil cools too much grass seed won't germinate at all.  Germination at least 45 days before average first frost is a common rule of thumb to allow enough winter hardiness.
  • For spring seeding, regular early nitrogen is extra important to maximize establishment prior to summer conditions.  1/2# of N per 1,000 square feet at seeding as well as 1/2# of N about every 4 weeks for at least a few months can get the grass off to a good start (Note: 1.09# of urea dissolved in water / 1,000' = 1/2# of N).  The larger the droplets the better... I like a TeeJet TTI11004 spray tip for applying fertilizer.  Fertilizer should be rinsed off of the grass blades after application to avoid tip burn.
  • After germination has concluded, the grass only needs to be watered to the point of survival... 1 fairly light watering every few days is likely enough water during the first few weeks.  If you see the grass start to wilt more water is needed... if it is raining, it's best not to water are all.
  • Once the grass is a few weeks old, not enough water is usually better than too much, since disease loves excess water!  We recommend owning a soil probe; If you aren't sure if you should water, simply pull a soil core or two... cores should be quite dry before water is actually needed.  Water between 0.5"-0.62" per watering with at least a few dry down days between waterings for best results.  Time of day matters with water... watering should be concluded around the time that sunlight first hits an area (often some time before 8:00AM).  Evening & night watering maximizes disease pressure and watering during daylight hours can be much less efficient due to excessive evaporation prior to percolation.
  • With rare exception, I recommend avoiding potassium, micronutrients, and phosphorus like the plague and just apply nitrogen to get the best possible turf quality with the least amount of problems and work but cold areas may benefit from applied potassium to reduce winter kill if potassium is low enough.  Foliar iron is ok, but I personally don't use it.  Before you assume a soil applied product is going to improve your soil, we recommend taking a cold shower, slap yourself in the face (if necessary), and then binge Turfgrass Epistimology study reviews on YouTube until the urge to purchase a given product subsides.
  • I believe in full renovations rather than overseeding when a major upgrade is desired.  Overseeding yields comparatively poor germination rates and the original (generally less desirable) grasses will largely survive and water down your results.  The value for time with full renovation is there in my experience.
  • Observe the 1/3 rule with sharp blades.  An All American Sharpener style grinding jig is great if rotary mowing, and a flat file can be used to push the burr off for that last bit of sharpness.  The 1/3 rule is per day or two... not per pass.  If you can't mow frequently enough to observe the 1/3 rule, bringing the height of cut up allows more time between mows.  1/3 of 4" allows more growing time than 1/3 of 2".

  • If the ground is mushy to the touch, try to wait for a dryer day to mow if possible.  Most compaction happens when ground is too wet.  The easiest way to cure compaction is often to prevent it, but of course, sometimes compromises have to be made to keep grass height under control.

  • Where there's lots of shade, mow higher or consider TTTF or fine fescue.

  • Where there's traffic, more nitrogen is needed.

  • Where there's shade, less nitrogen and a higher height of cut can improve survival.

  • Nitrogen rate should match growth potential.  If it's growing slowly due to heat or cold, lower rates should be applied or none at all.  Avoid medium or heavy nitrogen applications in summer to reduce disease.  In the most mild of areas sometimes the highest growth potential (and the most N) happens during summer.  If you see dollar spot, red thread, or rust, those will generally improve when nitrogen is added as long as temperature or light isn't the limiting nutrient.  Heat loving diseases that prefer high nitrogen include brown patch, pythium, and leaf spot.  Try to take nitrogen timing and rate seriously to reduce disease pressure.  We do offer a customized nitrogen schedule service here if interested... such might be cheaper than extra fungicides and also offer nice color and better drought performance over time vs. guessing at nitrogen.

  • This product will almost certainly contain some annual rye as is typical for perennial ryegrass seed (around 0.5%).  We recommend not allowing field conditions (keep it mowed during the seed head stage) until after all seed heads are cleared to ensure annual rye is not a reoccurring annoyance the following year.

  • Perennial rye has unusually nasty woody seed head stocks that can leave a yellow hue to your lawn for months and months if not addressed.  An annual "seedhead reset" can greatly reduce the effects of this undesirable trait of ryegrass (see below).  A seedhead reset is moderately stressful to the lawn and ideally should not be attempted under times of high disease pressure or other major stresses.

How to do a seed head reset:

  1. Once the annual seed head stage starts each year, mow at the usual mowing height for about a month
  2. Then, mow often (with very sharp blades) and gradually reduce the mowing height over the next few weeks to cut as much of the seed head stock off as possible, but make sure you stay above the crown of the plant to ensure less stress while the plant regenerates.
  3. About 1 week before the last mow, apply approximately  .3# of nitrogen and make sure the lawn is receiving around 1" of water per week via rainfall and irrigation (early AM water is efficient and minimizes disease pressure... around 1/2" of water every 3-4 days is an approximation for most areas during drought.)
  4. Return to your original cutting height.  The seed head stocks should be hidden below soft new blades of grass and the straw colored  seedhead stocks should be well hidden from view.

*  The performance of one older cultivar in this blend has been translated by sorting the 2011-2014 NTEP trial data into a percentile among all cultivars in that trial on a trait by trait basis.  The rating of the cultivar at the same percentile per the 2017-2021 data was then assigned to the older cultivar trait by trait.  No deduction was made for 7 years of breeding with the Infusion (AKA: JR-178) cultivar for the 5-Iron blend or the Pangea cultivar in Ryan Knorr's Elite Rye.  These numbers are intended to estimate performance as accurately as possible but it should be considered an estimate only.

**  Slightly older infusion cultivar exempt from averaging for 5-Iron and the slightly older Pangea cultivar exempt from averaging for Knorr for this performance trait due to difficulty of translation.
