How To Get Rid Of Rust Fungus On Grass: A Quick Guide

Finding rust fungus on grass is a common problem in gardens. This is why you need to know how to get rid of rust fungus on grass.

Rust fungus is an obligate plant pathogen that infects living plants like grass. You should know how to get rid of it before it becomes a very serious problem. Rust fungus is predominant in early fall or later summer when the growth of grass is relatively slow.

How to Identify Rust Fungus

It is easy to identify rust fungus by pulling a few blades of grass out of your lawn. If the blades are covered with yellowish-brown or orange-red spores, or dust, they are infected with rust fungus. You can actually rub the spores off with your finger.

The affected area will also become weak and thin. Fine fescue, bluegrass, ryegrass, and other dark-colored grasses are particularly vulnerable to rust fungus. Rust fungus usually develops in areas where there’s excessive moisture on grass blades.

Rust fungus reduces the ability of the grass to photosynthesize. Lawns that are infected with rust fungus also look unhealthy. The lawn will eventually become weak and sustain damage easily. The rust will also cling to clothes, garden equipment, and shoes.


How to Get Rid of Fungus on Grass

Rust fungus can be treated without using fungicides or chemicals. Here are natural remedies that can help you get rid of rust fungus on your lawn.


Mow regularly

Scalped lawns are more susceptible to fungal disease, so make sure to mow your lawn to the right height. Mowing the lawn regularly eliminates the top layer of rust fungus, and promotes rust-free grass growth.

Use a mower that comes with a grass catcher to keep your lawn clean. Don’t forget to wash the underside after using it. Rake, and remove thatch that becomes over 1/2″ deep as it provides the perfect breeding spot for spores and reduces air circulation.



You need to feed your lawn with the right amount of nutrients to keep it healthy. Rust fungus develops and spreads fast on slow-growing grass. Applying a nitrogen-rich, quick-release fertilizer to the affected areas will make the rust disappear quickly.


Mix up seeds

Seeding the lawn with various kinds of grass will help prevent rust fungus because it prefers delicate and dark-colored grass types. Rust fungus spreads easily when the lawn is composed of only darker grass types like bluegrass, tall fescue, and ryegrass.


Water the lawn each morning

Water the lawn every morning to give it enough time to dry out. Aside from preventing rust fungus growth, watering the lawn regularly also helps the grass grow faster. A thick lawn can fight off pests and diseases that prey on weakened grass.

Proper aeration is also important. Remember, fungi love damp soil with poor drainage. So, by reducing the shade your lawn gets, you can prevent rust fungus from reappearing. It will also encourage grass growth.


Use fungicides

Most fungicides have toxic chemicals that can harm the environment, so use this method only when necessary. Rust fungus may disappear on its own if the lawn is properly fertilized.




The Bottom Line: How to Get Rid of Rust Fungus on Grass

If you’re dealing with a bad outbreak of rust fungus, then you can apply fungicides for a quick fix. Make sure to read the label and follow the instructions carefully. Hungry, improperly irrigated, and stressed lawns are vulnerable to rust fungus.

That’s why you need to fertilize and water your lawn correctly. If you know how to get rid of rust fungus on grass properly, then your lawn will stay healthy and strong throughout the year.

How To Prevent Root Rot In Hydroponics: 3 Useful Tips

If you’re a newbie gardener who’s looking to find ways to hone your skills, you’d want to learn how to prevent root rot in hydroponics even before this problem affects your plants.

Hydroponics can be advantageous to crops in more ways than one. However, it also comes with risks of diseases, such as root rot, which can be destructive or even lethal to your plants.

Unfortunately, there are no effective methods to recover the wilted parts that were affected by the root rot once it hits your plants. The only thing you can do if you do not want this catastrophe to befall your crops is to prevent it before it happens. Read on to learn more about this subject.


What is Root Rot?

Root rot is a disease that attacks the plant roots and causes them to suffer decay. This usually happens when a lack of oxygen supply occurs in the substrate.

To give you an idea, think about plant roots that are submerged in water that only has a little oxygen in it. Over time, the plant suffocates and dies.

Aside from rot and decay, this disease also leads to the proliferation of fungi that are naturally present in the soil. These include Rhizoctonia, Alternaria, Pythium, Botrytis, Fusarium, or Phytophthora. As soon as fungi colonies start to grow, they tend to target the weakened roots and infect your precious plant babies.

Once the plant becomes infected, they won’t be able to take in what they need to grow – water, oxygen, and other nutrients. When this happens, it won’t be long before the plant dies.


What is Hydroponics?

In case you’re not aware, the term hydroponic is derived from a Latin word that means “working water”. To put it simply, hydroponics is an art that involves growing various types of plants without soil. If you’re like most people, the first thing that comes to mind when somebody talks about hydroponics would be a picture of plants with roots suspended into the water without using any type of growing medium.


Avoiding Root Rot in Hydroponic Systems

Detecting and identifying root rot can be tricky. When your plants get infected, their leaves and roots gradually wither until the whole crop itself dies from the lack of nutrients, which is a common symptom of many diseases.


What causes root rot in hydroponics?

One of the requirements in hydroponics systems is oxygen. Without it, your plants are basically on the road to death. On the other hand, lack of such is one of the major triggers for root rot, and it must be avoided at all costs.

Just like when planting in soil, you loosen up the ground so that your plants’ roots can have their required intake of oxygen. That is the case for crops grown in aqueous solutions as well. If they cannot breathe, they would not be able to grow.

Another agent for root rot is the temperature. The last thing you would want in your system are parasites that leech nutrients intended for your plants and infect the water during the process. In common terms, these fungi are called molds.

One of the best breeding grounds for these is warm and moist areas. For this reason, if the water temperature inside your reservoir is high, then you are susceptible to it. Something as minor as letting the solutions exposed to sunlight can already be a risk factor.


3 Useful Tips on How to prevent root rot in hydroponics

There is good news! Root rot in hydroponics can be prevented! Just follow these tips:

Tip#1: Use the right air pump

If you do not want root rot to affect your plants, you merely have to avoid its causes. If you need oxygen, keep the water bubbling by providing an air pump of appropriate size, and also give importance to proper ventilation in the room.


Tip #2: Maintain the temperature

The temperature should be maintained within the 70 to 80 degrees F range. Get rid of any materials that can make your system vulnerable to infections, and make sure not to disturb your crops while they are trying to grow.


Tip #3: Get rid of the rotten parts

However, if you failed in preventing the disease, then the rotten parts should be removed immediately. Cut them off as there is no chance of reviving them, and focus on the potential new growth instead. Fix your hydroponics system and eliminate the risks.


Why Give Greenhouse Gardening a Try?

Greenhouse gardening offers numerous benefits to greens aficionados who dare to take their gardening experience to the next level. Aside from acting as a shield against the effects of inclement weather, a mini, hobby, or semi-pro greenhouse can also serve as a protective layer that keeps harmful bugs and critters at bay.

What’s more, its enclosed structure allows you to control your plants’ growing conditions including the temperature, light, moisture, and ventilation of the greenhouse’s internal environment. With a controlled environment, you’ll be able to extend growing seasons and grow plants that aren’t native to your area.



No matter how well-informed you are about how to prevent root rot in hydroponics, you cannot completely eradicate the risks. Therefore, to avoid the worst-case scenario, you should be prepared to sacrifice the infected for the sake of others. While you’re at it, consider trying your hand at greenhouse gardening as well.
