Why is my lawn patchy?
Question:I got sod laid down in Feb of this year. When we got it, it was brown obviously due to the weather. It is growing out now and is nice and green, but it's in patches.
Is this normal? How can I get the whole thing to grow out?
I laid down fertilizer in the Spring and we water it for an hour everyday.
could be too much water, but i'm thinking grubs! spray it with a grub killer and it should clear up!
well if you have dogs that wee all over it then it will die where they weed, just pour a jug of after over where they wee immediatly after they wee to dilute the wee and the grass wont die
if you don't have dogs then i have no idea why it is in patches but you could buy grass seed to fill in the gaps, just make sure its the same grass seed that was used to grow the first grass!
too much water could also be a problem. put an empty tuna can on your lawn while you water it. as the tuna can filled by your sprinkler.. the amount of water penetrated to the soil should reached the lowest part of your grass roots. thats good enough.
when you fertilize it, make sure you follow the instruction, not too much, and you should spread it evenly. too much fertilizer in one particular area, might kill the grass there.
check the soil under the patch.. see if there's irregularity in the roots. perhaps there is 'something' there: ants colony, stones, fungi, whatever... just check a few patches/spots...
if all seems normal, I would mow the lawn -very short... fertilize it again... and usually this will clear the patch and, better yet... you will see new fresh look lawn...
goood luch... hope this helps...
Lawns only need one inch of water a week. Lay out tuna cans or other broad low vessel with a flat bottom of two inch depth. Measure how much water your system puts out in 15 or 30 minutes. A little ruler is all you need to measure the depth of water in the can. 1 inch a week. If temps go into high 90s give it 1 1/2 inches.
Mow the grass as tall as possible, no less than three inches high. If you cut off the grass blade low it has no green for photosynthesis. No plant can live long without the ability to photosynthesise.
Research at OSU with "Kentucky bluegrass has shown that root growth was more than twice as great when the grass was mowed at a 2.0 inch height verses a 0.75 inch height. In general, a lawn mowed too short will have a shallow root system with little total root mass. The impact of shallow, weak root systems is most apparent during summer stress periods."
To test for the presence of pests, peel back a 1ft-square area beside a damaged spot, and look for evidence of insects. If you find more than five to eight insects or grubs, you probably should treat your lawn. It's not necessary to treat if you find fewer pests.

If you see more than two or three armyworms, five or six sod webworms or a single cutworm in a 2' by 2' area, it's time to treat your entire lawn to a soap drench [Mix 2 teaspoons dishwashing liquid per gallon water]. Or apply the bacterium Bacillus thuringiensis to treat the foliage that the caterpillars feed on. They above web site list chemicals to use once the critter is ID.
