When lawns are underfed and improperly watered it can cause lawn disease. These practices can create ideal conditions for lawn fungus to form.

Fungicides can be applied as needed, but it’s more of a topical fix treatment and doesn’t solve the initial reason that your lawn fell victim to disease. The most effective way to prevent lawn disease is with a solid maintenance program that includes proper watering, fertilization, mowing, regular aerations with overseeding. All of these lawn care practices will help you have a healthy lawn with a strong root system that will be able to withstand lawn diseases.

Ascochyta Leaf Blight

Leaf blight causes a rapid straw to bleached appearance of the leaves, primarily on Kentucky bluegrass and to a lesser extent on perennial rye-grass and tall fescue. It is easily identified because the tips of the grass blades turn brown and look like a pine needle. Leaf blight is a fungus often instigated by sudden change in weather to dry and hot conditions.

Although a fungicide can be used, leaf blight will usually resolve on its own and we generally do not recommend treatment unless the problem becomes chronic. Proper watering along with a regular aeration are the best ways to help prevent it.


Bentgrass is a low growing dense grass. It is what golf courses use on their putting greens and when kept very short it looks neat and uniform. If it is left to grow freely it turns into a scraggly patch that can take over a lawn very quickly. You can usually spot these Bentgrass patches at a distance from their blueish tint or sometimes neon green tint.

Once it starts showing up as patches in a lawn it can quickly push out desirable grass and transform your entire lawn into a dense odd-looking mess. It is very common in many subdivisions and once you gain an eye for it you will be able to drive in your subdivision and spot the lawns that have Bentgrass in them. If it shows up in your neighbor’s lawn, odds are it will pop up in your lawn as well.

There are a few methods to use to treat Bentgrass. One way is to spot treat the patch with a non-selective herbicide during a summer day when Bentgrass is actively growing. A week later, mow over the area and aerate and overseed. This method may work if you just have a couple of smaller patches and you don’t mind having some round up patches of dead grass in your lawn until it fills in with new grass. Another method to use, especially on lawns heavily covered in Bentgrass, is to give us a call. A special herbicide is applied three times in the fall and then the lawn is aerated and overseeded.  This herbicide is not cheap, but this method is much less expensive than having to tear out all of your lawn and start over.

Powdery Mildew

Powdery mildew is a lawn disease that mostly effects bluegrasses and fescues. Periods of low light and poor air circulation favor the disease. Heavily shaded areas are particularly susceptible. The disease is most severe during spring and fall at temperatures between 60-72°F.  Its name is very descriptive as powdery mildew is easily identified as a white mildew on the leaf blade of the lawn.  It can also affect trees and shrubs.  As with most diseases like this the best way to treat the problem is to change the environment that is causing it.  Look at your watering schedule and make sure your lawn has time to dry out before the next watering.  Prune and thin trees and shrubs to allow more light and air circulation into areas being affected.

Red Thread

Red thread is a parasitic form of plant life called fungi. Fungi live in the soil, thatch and dead leaves year-round. These fungi feed off the grass and draw nutrients from it. Red thread can be caused by improper mowing and watering, and affects most types of grass but is commonly found on fescue and rye lawns.

Red thread happens in certain weather patterns and thrives in cooler temperatures with moisture. You will most often see it in the spring or fall. It initially appears as tan or reddish patches in your grass and upon closer inspection you will see red thread-like grass blades. The disease most often grows out once the weather begins to warm, but generally returns as the temperatures cool back down again. Most of the time a good high nitrogen fertilizer will take care of it.


Rust is a relatively minor disease in the Treasure Valley however, we do see it every year. Most cool season grasses are susceptible to lawn rust. Perennial ryegrass is the most susceptible while Kentucky bluegrass is slightly less susceptible. Rust generally appears on lawns in late summer and fall and is most active during conditions of low light intensity. If you have ever walked through a lawn and had brown coloring on your shoes it was probably due to rust.

The first signs of rust that you will notice will be small, yellow spots on the blades of your grass. These spots will grow larger and at some point, will turn into orange or reddish clusters on your lawn. Eventually, the disease causes the grass to thin out and die. Rust spreads via wind, so once you see it show up, make sure to give us a call.

Snow Mold

  • Mow your lawn a little shorter than usual in preparation for winter. Extra-long grass is a breeding ground for snow mold.
  • Rake up your leaves and keep your lawn as clear as you can. Leaves, snow and debris can suffocate a lawn and is an ideal environment for snow mold.
  • Go easy on nitrogen as too much applied late in the season can invite snow mold. Make sure your last lawn food application is a quality slow-release lawn winterizer.
  • Avoid creating large piles of snow as you clear snow from sidewalks and driveways. Deep snow piles on the lawn take a long time to melt which can increase the likelihood of snow mold. Rake the infected area to break up the crusted, matted grass as soon as the weather permits.
  • If you suspect snow mold in the spring, overseed the damaged areas of your lawn to speed recovery.

One major common winter disease is snow mold. Snow mold, also known as snow rot, occurs when snow, leaves or other debris stays on the ground for extended periods of time during the winter months. The longer the lawn is suffocated the more the snow mold will spread. Here are a few helpful tips to prevent snow mold from occurring on your lawn:
