A gentle wake up for a lawn coming out of hibernation

A nice gentle blend of slow release is just what my slumbering lawn needs as it wakes up slowly to get ready for the long dog days of Florida summer. The order was placed and arrived in no time at all. Kudos to the creators of this blend and the staff that makes the machine run smoothly.

Stress Blend

It's very good. The grass got greener and some on the areas that weren't so green got green. Very good result on my grass. So thet mean that the quality of the product is very good.

Raised my Potassium level

The soil test kit indicated that my N was good, P was High, and K was low. Two applications of stress blend brought my soil test into optimal range and the grass looks great!

Just buy it!!!

I’ve had two great experiences with this product. 1) Saint Augustine: Lawn looked terrible. One week later begin to see improvement. By the 4th week the lawn went from patchy to flourishing. Owner was even considering applying new grass but this product made a great turnaround. 2) Bermuda (My lawn): I apply once the grass is actively growing out of its dormant stage. Definitely helps wake up and boost lawn to a great spring green up. I also apply this product in summer to help with those drought days.

This product helps me keep my grass thick and super green. I get lots of compliments and inquiries on how I keep my grass so perfectly green. But no sticker in the last shipment, I was bummed…

Lawn Therapy in a Bag – Perfect for Stress Recovery!

If your lawn has been through heat waves, drought, frost, or just general wear-and-tear, 7-0-20 Stress Blend Fertilizer is exactly what it needs to bounce back. I picked this up because I wanted something that wouldn’t push too much top growth but would help my grass recover and stay healthy—and it delivered big time. What I Loved: ✔ Perfect for Stressed Lawns – With low nitrogen (7%) and high potassium (20%), this formula is all about strengthening the lawn rather than forcing growth. My grass was looking dull and tired after a tough season, and within a couple of weeks, it perked up beautifully. ✔ Deep Green “Color Pop” – I was skeptical about the promised rich green color, but it really does pop! The 3% iron + micronutrients make a big difference in overall turf health. ✔ Year-Round Versatility – Great for spring wake-up, summer survival, and fall prep. It’s especially handy if you want to feed your lawn without overstimulating it. ✔ Moisture Management – The high potassium (potash) content is a game-changer for helping my lawn retain moisture during hot spells. I noticed it stayed greener longer, even with limited watering. Things to Consider: 🔹 The Smell – The Bio-Nite™ biosolids definitely have a distinct scent when applying, but it fades after watering. If you’re used to organic fertilizers, it’s not a big deal. 🔹 Not a Growth Booster – If you’re expecting fast top growth, this isn’t that kind of fertilizer. It’s designed for stress recovery, not aggressive growth spurts. Final Verdict: � This is hands-down one of the best fertilizers for stressed or recovering lawns. Whether it’s heat stress, drought, frost damage, or general wear, 7-0-20 Stress Blend helps bring turf back to life without forcing unnecessary growth. Would I buy it again? Absolutely! It’s a must-have for both warm- and cool-season grasses, especially during the most challenging seasons. Highly recommended for DIY lawn lovers who want to keep their turf strong year-round!

Packages were sealed but product was damp and did b not spread well Spreader setting of 5 1/4 was not enough and I had to increase to about 7 so that product could release, but coverage was not accurate. Disappointed. 5 1/4

Follow the Program, IT WORKS!

I have warm season grass. I used Stress Blend last fall, followed again this past January with another feeding of Stress Blend. My grass looks GREAT in late February. I've been a DIYer all my life, BUT never has MY plan made my grass look this good. I used a few products last year throwing them down without a plan. These current results make me a believer. My recent soil test was also helpful and I've ordered Yard Mastery's recommendation from the soil test. Good Luck Thrower Down!!

Winter Soldier Fertilizer (7-0-20 Stress Blend) – Perfect for Winter Prep!

I applied Yard Mastery’s 7-0-20 Stress Blend with Bio-Nite heading into winter, and my lawn is holding up strong. The potassium (20%) boost is exactly what my grass needed to stay resilient against cold stress, and the 3% iron kept it looking rich and green even as temperatures dropped. This fertilizer isn’t about pushing growth—it’s about fortifying your lawn, so it survives winter and comes back stronger in spring. If you want a winter-ready lawn that can take a beating and bounce back, this is the one. 💯 Highly recommend. Will be using this every year

Quick Green Up

I live in Hillsborough County (west-central Florida). My St. Augustine lawn had a yellow tint that I could not resolve. On February 1, 2025, I applied Stress Blend, MicroGreene, and RGS. In the three weeks since, the yellow has disappeared, moderate growth has occurred, and the lawn looks healthier. I stand behind this product and will continue to use it in the coming months.
