How to Control and Treat Lawn Diseases

Keeping your lawn healthy takes work and effort. And, recognizing the problem goes a long way towards solving it. Here are some tips on recognizing problems and the solutions you can use to get your lawn healthy and green again.

Brown Patches In Lawn

Many people have the same question asking: “Why is my lawn brown?” Well, generally, this can be caused by brown patches, which are common in many lawns. These brown spot diseases are circular brown spots that can range from 1 inch to several feet.

The grass will look brown and water-soaked at first. Then, they will dry out. This lawn problem is most common when the humidity and night temperatures are high.

To get rid of this disease, you will need to water in the mornings only. Lawn lime will also help. Do not leave clippings on the lawn, as this is an environment that fungi will enjoy. If it is possible, reduce the shade on your lawn.

The brown patch is best prevented by aeration of the area, reducing shade, follow a regular fertilization schedule, and avoiding over-fertilization. Fungicides like chlorothalonil and benomyl usually work best in such cases.

Cottony Blight

Cottony blight is common in lawn grasses with damp soil in areas that are hot and humid. If you see fungi that are cottony in appearance, your lawn has this disease. It is easiest to see in the dampness of the early morning. The best remedy is to reduce the nitrogen, improve the drainage and increase circulation.

The circulation can be increased by pruning or thinning shrubs in the surrounding area. You will also need to reseed the affected area.

Fairy Rings

Fairy rings are circular rings that can range from a few inches to 50 feet in diameter. This fungus does not attack the grass. It interferes with the roots. It will prevent the root system from taking in water, oxygen, and nutrients.

You can control this lawn disease by soaking and feeding the area. The only cure is replacing the sod or fumigating. These remedies are expensive, so it is best to keep the area watered and fertilized.

Fairy Rings is a lawn disease that you can easily treat. It tends to look like dark circles or mushroom circles. If you see the mushroom circles, you can rake them off. They really do not affect the grass, but this is the real disease if you see dark circles.

The circle will get bigger every year if left untreated. This is not a serious problem, but more of a cosmetic one. Treatment: Apply ample amounts of water, and use a good fertilizer to stabilize the root system.

Fusarium Blight

A common disease that may afflict your lawn is Fusarium blight. It is most common in the central and northeast states of the US. It can be detected by small tan spots that will appear in early summer. It is best to prevent this disease rather than try to cure it. Use seed or sod that are resistant to blight. Be sure to water your lawn thoroughly.

Invasive Plant & Kudzu Removal Tips

Warm, humid weather creates the perfect environment for kudzu to grow. And when it grows, it seems never to stop. As temperatures rise in the southeastern United States, the green blanket of kudzu growth will soon envelop hundreds of acres of land in areas like Roswell, Georgia.

The invasive vine has been troublesome for property owners throughout the subtropical areas of America since the late 1800s, when it was introduced as an ornamental plant for shade cover in New Orleans. It spread from New Orleans to other areas of the south as the perfect solution for soil erosion.

Now, kudzu is seen as a menace and a stubborn one at that. Kudzu removal attempts range from spraying it with herbicides before it shrouds other plant species or mowing it down – only to watch it creep back – are nearly futile.

Invasive Plants

Kudzu is described as an invasive plant not native to the United States, which means that it does not have any environmental factors, such as predators, to keep it under control. Thus, when temperatures are ideal, it grows without bounds.

The vine originated from southern Asia, an area of the world with similar subtropical temperatures indicative of the southern US. In fact, states like Mississippi, Alabama, and Georgia are plagued with the plant because of analogous climates.

The tenacious plant engulfs nearby shrubs, trees, and underbrush with little resistance. Comparable to wisteria, it quickly climbs tall trees – typically pines – to reach the sun’s rays and soak up any rainfall.

What was once a majestic tree in the fall has now become an anchor for kudzu’s sprawling vines, making a forest look more like a jungle through the hot months of the south. The growing season is typically June-October, which is plenty of time for healthy trees to become husks of their former beauty.

Common Removal Methods

Though common methods of mowing or clipping kudzu vines effectively keep them at bay during the growing season, they are only temporary.

Herbicides have succeeded in combating future growth, but the amount needed to eradicate several hundred acres of growth is enormous and becomes quite costly. It can also take years of dousing the vine’s root system with large quantities of herbicides actually to see results.

New Resolutions

But, some landscapers have become quite creative in their kudzu removal methods. Soil solarization is a chemical method of kudzu removal that proves more effective than herbicides and is safer to use than dangerous pesticides. The method involves solar-generated heating in the soil to kill the root system.

In essence, the micronutrients and macronutrients in the soil are afflicted, and potassium increases. The best way to eradicate kudzu is to destroy the root crown, which lies beneath the surface.

Outside of mowing or spraying kudzu, the most effective way to destroy the plant is to remove the root crown. And, because it seems to be the king of the south, it only fits to remove its crown. The hard and fast of it is, there’s a way to get rid of kudzu, but it’s no easy task.

1. Soil Ph levels

One of the most common culprits to bad lawn growth is the ph levels of the soil. The soil in your garden is just as prone to collecting pollutants and harmful chemicals that make a poor breeding ground for grass in much the same as flowers.

To make sure you are using the right products and treatments for your lawn, you must start in the best possible way by measuring and checking the ph levels of the soil your grass is growing on.

This is easily done by contacting your local eco advisory service or board, who will give you a sample bag to take a test of your lawn and respond to you with the correct products you will need to restore the soil to optimum nutrient levels that you need for healthy grass to grow.

2. Watering

Many gardeners will know that it’s a good idea to put the sprinklers on when the weather becomes dry, but what many do not know is that watering your grass in the morning gives it the best chance for healthy growth.

Overwatering can also be as harmful as under-watering, so if you have watered your grass, wait for it to dry before watering it again to make sure you are not drowning your grass.

3. Mowing

Moving the grass is another must do to keep it healthy. Rather than letting your grass grow to dangerous levels and then cutting it as short as possible to save time and energy, it is better to mow your lawn regularly to around an inch or two high, which is the optimum height for healthy grass to grow.

Cut shorter than this, and the roots of your grass will be overexposed to sunlight and pollutants, leaving the grass to grow too long. The shade of the longer blades of grass will underexpose the roots to the sunlight, water, and nutrients it needs: both overgrowth and overcutting will lead to the same conclusion: death to your grass.

4. Nutrients for your grass

Just like flowers, grass needs nutrients to thrive, and so if you are treating weeds and other unwanted visitors to your lawn with harsh chemicals, you are polluting your grass with the same chemical.

To balance out the treatments you are putting on your lawn in the form of weed killer and other harsh treatments, remember to give your grass nutrient.

A cheap and easy way to do this is to scatter mowed grass over your lawn, leaving it to decompose on the grass and fill the soil underneath with valuable nutrients that will help it grow.

If you follow these simple steps, your lawn should be looking great in no time at all. However, if you still are suspicious of the health of your lawn and want to seek professional advice, then the best thing for you to do is to bring in specialists to perform a healthy lawn examination and analysis on your lawn and cure all identified diseases. You’re going to have your lawn stay healthy all the time from now on.
