My Entire Lawn Turned Brown In Fall
If you live in a warm climate, theres likely no need to worry. Warm-season grasses like zoysiagrass or bermudagrass turn brown in fall season to prep for winter. As temperatures cool down, warm-season grasses go dormant to protect themselves from winter elements, and then theyre back in action come springtime.
As long as your lawn is pretty evenly brown, and not covered in blotchy brown patches, you dont need to be concerned.
Why Is My Lawn Brown Some Symptoms To Look For
Getting to the bottom of your lawn problems all starts with a little bit of sleuthing. The truth is, dead spots in the lawn can be caused by quite a few different culprits and determining which one is at fault isnt exactly easy.
It can help to look for specific symptoms to clue you into what might be causing the brown or dead spots on your lawn. Here are some things that you might notice as you dig deeper into your Pennsylvania lawn problem. Well get into more detail about the causes of these symptoms later in this article.

How To Prevent Brown Patch
The fungus thrives on conditions that leave your lawn damp for 48 hours or more, making mid-late summer prime time for it to thrive with damage rearing its ugly head in the fall. Not to mention excessive irrigation, rainfall, and humidity all exacerbate the problem. For this reason, water management is key to preventing brown patch. Irrigation should only be used to supplement rainfall. Rain sensors and smart controllers solve for this and ensure youre not overwatering.
One of the toughest parts about treating brown patch is that its likely to reoccur in lawns that have previously struggled with the fungus. If your lawn tends to be affected by brown patch annually, your landscape partner will probably prescribe a prophylactic fungicide application in the fall, with follow-up applications at regular intervals as the weather continues to cool.
Even if your lawn has been spared, you should still remain vigilant. Brown patch can remain dormant in soil for years until favorable conditions are achieved. In fact, some properties that struggle with brown patch might notice signs of infection subside when the weather warms, only to return later in the year when conditions become favorable once more.

Cultural Management: Preventing Brown Patch Lawn Disease
Since high levels of fast release nitrogen increase disease activity, Spring-Green uses a correct blend of fertilizers for lawn fertilizing during the warmer months. Mow less frequently during periods of hot and humid weather, this reduces stress and limits the movement of grass disease by being carried on your feet or mower. If possible, increase light and air penetration, or movement, by pruning overhanging trees and shrubs. During cooler seasons, open up the thatch layer with power core aeration. If these cultural cures fail, a preventative fungicide lawn treatment program may have to be applied to control this most damaging of lawn diseases.

Factors That Cause Brown Spots In A Lawn
When your lawn is covered in unsightly brown patches, there’s no splendor in the grass. Even with lots of care, fertilizer and regular waterings, various problems can turn green grass brown, so consider what the culprit might be before taking action. Keeping lawns in good health helps prevent many problems though, and also ensures grass recovers quickly.
Large Patch Or Brown Patch
The most common disease affecting grass in our area, a fungus called rhizoctonia manifests as large patch in warm season grasses and brown patch in cool season grasses.
As the name suggests, large patch causes sizeable areas of diseased grass in an otherwise healthy lawn. Damage is often circular and can range from less than three feet to 25 feet in diameter. The foliage typically dies back from the leaf tip toward the base, and the more recently affected grass along the edges may appear orange.
In cool season grasses, like tall fescue, brown patch may cause rings or patches of damaged grass measuring five inches to 10 feet or more in diameter. Leaf spots may be noticeable on broader leafed varieties, and new leaves may attempt to grow within a blighted area.

More obvious signs to identify brown patch lawn fungus are circular areas of brown and dead grass surrounded by a narrow, dark ring. Patches are typically irregular and can be quite large, as this disease can spread fast.
This brown spotting can take on different appearances depending on the characteristics of the grass it infects. The following are signs of brown patch based on the type of grass you may have in your yard:
- Closely mown grasses: Any grass you should cut short, like some Zoysias, will show circular rings of brown patches and an expanding gray ring on the outer edgemost noticeable when the grass is damp, especially in the early morning hours.
- High-cut grasses: Grasses that are kept taller often exhibit circular or nearly circular brown areas, but without the visible details of gray exterior.
- Tall fescue: Tall fescue varieties often don’t exhibit the characteristic circular patterns. Rather, the fungus will appear on scattered blades of grass, so that the whole lawn may seem a little off, with a tannish cast rather than the vibrant green you want to see.
Common Lawn Diseases And Pests
If youve eliminated all the above causes, its time to move on to some of the more serious diseases and pests that plague lawn grasses. Some of the most common culprits are:
Thatch: Thatch is a buildup of decaying grass blades that can build up so thick that it chokes out healthy grass.
Remedy: Remove thatch if it is more than ½ thick.
Grubs: Grubs are a common problem in mid to late summer, and most easily identified when your sod easily pulls back from the ground like a carpet.
Remedy: Pull back a section of sod and inspect for fat, white curved worms. More than ten per square foot can cause lawn damage. Grub control products are available at your garden center.
Chinch bugs: Chinch bugs are a common summer pest in warm-season lawns, especially in hot sunny patches beside driveways and sidewalks.
Remedy: Inspect your lawn closely, and look at your shoes as you walk through the grass you should be able to spot the small black and white adults. Theyre resistant to many pesticides, but there are products available to target them.
Other insects: Caterpillars and other pests can live part of their life cycle in lawns.
