The Andersons HumiChar emendamento organico del suolo con acido umico e biochar copre 12.000 piedi quadrati (12 libbre)

Q: Is this product organic or natural ? would the product burn the lawn grass if putting too much? Thanks!

No it’s not organic and even though you can put to much at one time on your lawn, it doesn’t burn as fast as your traditional fertilizer. This product is really mild however it’s always recommended to put it down at the recommended rate.

Q: 4.5 setting on my Scott's edgeguard for the 18 pound bag only got me coverage of barely 3,000 square feet. I don't see how that would treat 5k sq ft?

Lower your spreader setting or walk faster. Either will thin out the application a bit for a broader coverage. I'm rather OCD and I use a lower setting and do a pass in one direction with half the bag, then put the other half in and go across the lawn at a 90 degree angle for a more even distribution. Also, I recommend buying the larger bag as it is cheaper per pound, then just roll up the top and tape it and stick it in the garage or shed for the next application. I first used this in 2020, and the larger bags were not available, which means I need to probably go ahead and start looking for some now. Look at big box stores over the winter when they are trying to clear shelf space for the holidays and you can find lawn care stuff frequently at reduced rates. This left darker green stripes on my lawn which wasn't the fault of the product, but my lawn was deficient in iron. If you have this happen, adding more iron should help even out the color. Ironite is one popular choice. There are also spray on liquid iron applications if you need a quick fix for a lawn party or something.
