Dry grass in lawn

Hi all, 

We're  first time homebuyers and we just mowed the lawn for the first time.  After a few days we started noticing dry patches of grass in our lawn and we can't figure out why this dry patches exist.  We water the lawn every alternate day so wanted could not be the reason why it's dry and we usually water in the night around 8:30 PM . Could this be chinch bug or is it anything else?   How do we fix this problem and when the grass ever go back once we spray something .   Thank you all in advance for your help

First off, never water at night.  Moisture on the grass can lead to problems, mostly with diseases.  Water in the early morning and water deeply but infrequently.  If the grass is watered lightly the roots don't grown down into the ground because water is at the surface and that isn't good for the plant.  About an 1" of water per week is enough, put out some flat pans so see how much you're actually watering and time how long the sprinkler in on.  From there you can calculate how long you need to water.  You will probably need to break the yard into sections, watering section A on Monday, section B on Wednesday, section C, on Friday, etc.

I don't know where you live but if you live in the northern tiers of the country and from the picture it looks like you have "cool season" grass (rye, fescue, bluegrass, etc.).  Most people cut their grass way too short.  Cool season grasses should be 3- 3 /12" tall and don't cut more than 1/3 of the grass height on any one cut.  Leaving the grass taller makes for a healthier plant and helps prevent weeds because the taller grass blades shade the soil which makes it harder for weed seeds to germinate, which means you spend less money on weed killers.

Keep you lawn mower blades sharp because dull blade rips the grass rather than making a clean cut.  That leaves the grass open for diseases.  Sharpening a blade isn't difficult and we can walk you through the process if you need help.

As for your brown patch.  I might suspect some type of disease but you really need a close up of some of the grass blades to tell for sure.  If you pull on the dead blades, does the grass pull out of the soil easily?  If so, that might indicate grubs.
