1. Insect Infestation

Insect on the grass can also cause your ornamental grass to die.

Identifying whether the insects are the ones causing the death of your plants or not is easy.

Simply run down your fingers up and down a blade of grass that is in the soil to find out.

Aphids and mites are the most common types of insects that attack ornamental grass.

For instance, aphids kill grass when they suck out the sap.

They are normally found on the underside of blades.

While mites suck the juices from the blades, making the infected parts yellow.

Unlike aphids that you can see with your naked eye, mites cannot be seen.

However, you can see their webbing on the grass.

How To Fix It

Getting rid of insect infestation from your ornamental grass is easy.

As long as the ornamental grass is healthy, it will resist insects and other pests.

For this reason, you should care for your ornamental grass by watering and fertilizing it as needed.

Never allow your plants to become extremely dry as mites get attracted to dusty environments.

Besides, you can get rid of mites and aphids on the plants by spraying insecticidal soap spray. Don’t use poisonous chemicals that may kill beneficial insects.

2. Overwatering

If your ornamental grass starts to brown, then it may be due to overwatering.

Most types of ornamental grass don’t need overwatering as they don’t thrive in incredibly moist soil.

After watering your ornamental grass, you should give it time before re-watering.

This will ensure that your grass doesn’t lack water or has excess water.

On the same note, if you don’t water your ornamental grass properly, it will brown and die.

How To Fix It

Always ensure that your plant is well watered and not under or overwatered. Your pant will grow smoothly and without any issue as long as it is fed with the right fertilizer.

3. Poor Care

Some people plant ornamental grass without considering what is needed to make it grow well and healthy.

As a result, failure to care for the ornamental grass may make it die.

First and foremost, ornamental grass cannot be grown in any climate.

They prefer a sunny climate with some exceptions such as fountain grass, maiden grass, and sea oats that can thrive in partial shade surroundings.

Aside from requiring a sunny climate, most ornamental grasses need properly drained soil, with the omission of umbrella grass, which flourishes in muddy conditions.

How To Fix It

If you’re not taking care of your ornamental grass, you should start doing so.

Ensure that the conditions are right, and you’re growing the right type of ornamental grass in your location.

Furthermore, regularly check the grass for diseases, pests, and protect it from being destroyed by animals.

4. Diseases

There are various diseases that can attack your grass and kill it. Some of the common diseases include powdery mildew, grass, and smut.

Let’s start with the powdery mildew. This is a fungal disease that can be spotted by powdery blotches on the leaves.

Extreme infection may cover the whole ornamental grass with the powdery blotches.

This problem is common in shady areas as powdery mildew build-ups in warm, humid conditions.

Rust is another disease that hurts your grass. It appears on the blade of the grass as a small reddish-orange or yellow blisters.

And when the disease spreads further, it changes to brown or yellow.

In the worst-case scenario, the grass blades might wilt or die.

How To Fit It

For powdery mildew, you can stop its spread by applying a commercial fungicide. Additionally, you should plant ornamental grass in sunny areas where fungi won’t develop easily.

And for rust, you can stop its spread by getting rid of affected sections of the grass.

Also, you should water the plant from the base, instead of overhead watering, which promotes the growth of rust.

5. Attack By Animals

Deer, rabbit, and slugs may also destroy the ornamental grass. These may kill the plant entirely if they feed on it more regularly.

Slugs eat blades, which may lead to the death of your grass slowly.

Rabbits also destroy the grass chew but not to a large extent as larger animals such as deer.

If you notice a small section of your ornamental grass is chewed, then you should look out for rabbits in your area.

And if a huge part of your grass is destroyed, then that is a deer.

How To Fix It

The good thing is that you can prevent your grass from being destroyed by identifying the animal attacking your plant.

If it’s a slug, you can make a trap for it and dispose of it. If it’s a rabbit, you can use a rabbit repellent.

And for a deer, you can also use a repellent to deter it from coming close to your plant.

6. Aged Plant

When ornamental grass gets older, the center of grasses usually die. If this happens, you should divide the grass and plant it again.

How To Fix It

The best time to divide and plant your old ornamental grass is during spring before new growth starts.

Final Thoughts

That’s why many homeowners include them in their residential landscapes.

If you notice one of the above signs on your ornamental grass, then you should fix it quickly to prevent your plant from dying completely.

Pests, diseases, and animals won’t go away, but maintaining your ornamental grass properly will keep them at bay.
