Good product for lawn
Used this when I overseeded and has helped to improve soil conditions

expensive product, it seems to be working as intended
While an expensive product, it seems to be working as intended. I can get two applications with a single bag, for my property. Keeping my soil in good condition for my Zoysia is what needs to happen, for me.

GREAT QUALITY!
I love The Anderson Company and use their products exclusively. They are BY FAR the best and my yard shows how well their products work. Well worth the money!

Order Direct!
For the $5 you save...it is not with the headaches of delays or busted boxes/bags!! Apparently they can't carry 40lbs. Or don't want to use cart!! Great products... Bad delivery service from Amazon! Three trucks in one small neighborhood is not efficient!!

Improving our soil
We use this in the yard and improve the soil for grass, as well as the flower bed. We had a spot of compacted soil that nothing would grow for quite a while. I sprinkled down Humichar and worked into the soil. Now have plants growing there when everything a few months ago would die.

Southern Sandy Soil Cure
If you live in the South and deal with sandy soil, I want to share something that truly changed my lawn: biochar. It’s not just hype—it works.When we bought our home, our soil was bleeding out nutrients and water faster than I could put them in. I ran soil tests and realized I was throwing money away on fertilizers that couldn’t stick. That’s when I started digging into real solutions—and that’s how I found biochar.Now, I apply it twice a year with the goal of reaching 200 pounds over the next few seasons on our front lawn. It’s an investment—$600 to $800 total—but here’s the thing: biochar lasts 100 years or more in the soil. It locks in nutrients, holds water, and transforms how your soil works.By the time my plan is complete, we’ll likely cut our irrigation needs by 40% and reduce fertilizer use by half—so it ends up paying for itself if you’re willing to be patient and consistent.Here’s what I’ve learned:• Charge the biochar with organic fertilizers—they feed the microbes and bring the biochar to life.• Add micronutrients and macronutrients when applying—it’s like seasoning the soil properly.• Stick with it. Every application improves CEC (cation exchange capacity) and builds the kind of soil plants thrive in.If you’re not sure how much to use, you can use tools like GPT (yes, the AI!) to calculate the right amount based on your lawn’s square footage and your soil goals. If your soil is sandy and struggling, this is one of the most powerful long-term changes you can make.Take your time. Stay consistent. You’ll be amazed at what your lawn can become with healthy soil.**04/15/2025 Update: Added photo of soil profile from a sod plug I pulled from my lawn. Look at the top profile with only 100 pounds added past 18 months! Good bye sand!**8/13/2025 Update: Centipede Grass and full lawn healed now that sandy soil is gone after 20 Months do yourself a favor and invest in biochar/humichar

Step 1 for a lush lawn
This is long, BUT READ THIS before wasting your money on other products.I've been attempting to fix my turf since 2021, when I moved into my new home. I initially hired a lawn service, but the success was short-lived.Last fall, I took matters into my own hands by dethatching, scarifying, and overseeding. After minimal success with germination (I took all the steps to protect the seeds and keep them moist), my lawn came up thin and light green in the spring. Despite heavy rains, my soil was still hard as a rock. My soil pH was high, so I bought Mag-I-Cal to lower the pH. I also bought Love Your Soil to loosen the hard clay. Those also had short-lived success. I knew my soil was the problem. The pH came down slightly, but the soil remained compact. I realized that years of fertilizer and over-irrigation by the previous owners had probably built a carbon deficiency and sodium chloride concentration. I read up on this product. It's everything you need to condition your soil on a more permanent basis. The charred component makes space for healthy microbes and the humic component feeds the microbes.I used fungicide to treat lawn disease this season, but as this product layers into the soil and improves water retention at greater depths with healthier root structures, I've had fewer indications of disease. I also have fewer urine burn spots from my dogs. The soil pH has neutralized as the soil retains more rain water (which is slightly acidic in my area).I treat my lawn with this every 2-3 weeks at a light/moderate rate with plans to continue to do so as it moves deeper into the soil.Start with your soil. Treat it heavily for 1 season before scaling back to maintenance applications. Cut your grass high and help the roots grow deep. Healthy turd is resilient and needs less care. I'll swear by this product and won't switch to Humic DG or PGF Complete for humic content until my soil is fully amended.This product is worth the money.
