One of my friends says he mixes his Anderson's surge with lime, and his lawns look great. So, could I mix my lesco (whatever they have me putting down on their schedule) and see those sane great results
Incorrect PH effects plants ability to absorb nutrients. Putting lime and fert down at the same time will do nothing unless you cause the PH to go out of range. Chances throwing down a bag of lime is not going to change PH very much.
However when the lawn is not growing as desired it is always wise to have a soil test done before anything is done. Whether to aerate, seed, fert, lime or anything else because it will be wasted material and work if there is a soil problem.
I do not think because I do not see a soil test in front of me.
Last year I had a customer with a very poor lawn. Lots of bare spots and weeds. Complained about how her past Landscaper was just running down her lawn, hardly growing, yet he showed up every week to mow it.
On top of her running her sprinklers too much they were coming on a 5:30 PM. That's 5 in the evening. It took over a month for her to get her daughter to get that straightened out.
I sold her on a soil test.
She had a PH reading so low LESCO said her lawn requires too much lime to put down all at once. That I had to put lime down when I reseeded, after the fall clean up, after the spring clean up.
I have had poor lawns where the PH was good.
You can not look at a lawn and know what the PH is.
I also do not think. I know that when their is a poor lawn a soil test is needed because the price of starter fert, lime, seeds are expensive as well as the labor charge, to waste money when the problem as to why the lawn is not growing is not detected and fixed.
