    A new customer called me to go look at his lawn. He told me that he had a perfect lawn before he applied a lot of fertilizer. A product called "vergo". he said he applied the first, and on the second time around he put a lot and got big brown dry patches in his yard? Is this from the product that he used or something else. I figured if it was the vergo all of his lawn would be messed up and not just parts of it.

    Probably used "Vigoro" which is a big box store fertilizer like "Scotts".

    That stuff comes in a fertilizer only or weed & reed.

    If he put it out too heavy he probably has fertilizer's that time of and dry...depending on where you are.

    Many homeowners are clueless when it comes to spreader calibration and settings...the burn areas are probably due to heavy overlap.

    Could have applied it too heavy

    If its fescue and he's gotten a lot of rain or irrigation it could be brown patch

    Vigro is a medium quality competitor to Scotts available at home Depot. Fert burn is pretty easy to diagnose. Are there straight lines? Burns same width as his spreader (19 inches)? Are there a high levels of particles of sulfur coat or inert stone dust in the spot? Did it appear about 48 hours after the application? Are nearby areas dark green? Did he stop and start without turning off the flow? Pull it backwards? Cover 3000 sq ft with a 5000 sqft bag?

    There are no straight lines its just big circular patches. The guy told me he did not follow application rates and really used the whole bag on a tiny tiny lawn. Dont know exactly how long it took but it happend pretty soon after he put down the fert. How should i go about repairing the brown patches? oh and im in VA so its got to be fescue.

    I am about 20 miles from you and with all the rain (5 inches already this month) and warm moist nights he has probably got the dreaded patch. Stay away from the fast release water soluble N.

    I suppose there is an abundance of Pre-M in the soil as well,,, so the chances of getting seed to grow is also going nowhere... I would not get too closely involved with someone who hasn't a clue about what he's doing,,, but has all the confidence in the world that he's doing good...
    I'll bet he's growing lots of species of Fungi with his irrigation as well... :)

    If he did have pre-m in his fert it will be a problem doing seed at all, so maybe sod... how is his irrigation sense??? too much water???
