I have a yard that was relandscaped/resodded in may. It is St. Augustine and I fertilized it after the 1st 6 weeks since it was laid down and then after the next 6 weeks as suggested by my Lesco guy. The lawn was BEAUTIFUL! Dark green, lush grass. I told my customer that it would be worth it to have a spray company service the yard to keep weeds out,fungus,pests,etc. Well, they spray and about 2 weeks later the lawn isn't looking as good as it did before. Some areas looked "dry." They go back out to look at it and say that they went a little heavier on the spray to make sure weeds don't break through and that it caused some areas to have stunted growth....does this sound right?? Will my next round of fert. help this?? This is my best property on a corner of a very busy intersection and i want it looking perfect.
