How To Remove Ornamental Grasses Best Guide

You can quickly grasp how to remove ornamental grasses in two steps. First, identify the type of grass you have and then decide whether to dig it up or use a herbicide. While gardeners often plant decorative grasses for aesthetic purposes, they tend to thrive and spread so quickly that you will need to remove some of them. 

The good news is you don’t need to hire others to do this job. Understanding and planning these grasses will also help you in the future. For example, you can choose clump-forming grasses next time because they are not as invasive as rhizome-forming grasses

How To Remove Ornamental Grasses Easily


Step #1. Identify the grass

Before the removal itself, you must know the type of ornamental grass that you have. This will give you the information on their growth habit to create a better plan for removal. For example, invasive species might require special care in removal and involves consultation with the extension in your area before eradicating them. 


Clump-forming vs rhizome-forming

As mentioned earlier, you can classify grasses into clump-forming and rhizome-forming types. It’s preferable to have clump-forming because they don’t have an invasive habit. Instead, they grow neatly in clumps, as the name implies. 

On the other hand, rhizome-forming grasses do not form clumps but spread via underground stems. There are still some popular ornamental rhizome-forming grasses, but careful planning for their location is necessary so that they won’t take over your other plants. 


Warm-season vs cool-season

Another way to classify grasses is via their growing season. Warm-season ornamental grasses grow in spring and summer and undergo dormancy in the winter. On the contrary, cool-season grasses will thrive in fall or winter.

Knowing when the grasses begin new growth, bloom, or go dormant would be useful in removing them. Additionally, this also helps with planning the next time you’re planting grasses. In the greenhouse, you can use the structure to your advantage and adjust the conditions to grow grasses. 


Option #1. Digging 

Now that you identified your grass’s type and habits, you have two options for removing them. The first one is digging up the ornamental grass, and most gardeners prefer this method because it doesn’t require chemicals. You only have to understand how the root system of these plants works. 

Unlike other plants, digging up ornamental grasses is better if you do it in groups or start in small locations first. The intricate and deep root systems of ornamental grasses make it likely for errors on the gardeners part because you can leave some root parts that will grow later. Digging up grasses at a time will ensure that you have eradicated the root system. 

The process of digging up grasses is straightforward. Use a shovel to do so while making sure you’re not leaving any part of the root system. For your convenience and a cleaner set-up, place all the grassses you removed in the wheelbarrow, and don’t forget to check your laws for proper disposal. 

You’ll also have an easier time digging them up if you cut the grasses down to 2 inches above the ground and section them into divisions using a sharp shovel. More so, it’s always useful to water the roots and soil for easier digging up.


Digging out the center of ornamental grasses

For maintenance, you might find the center of your grasses starting to thin out and die. You don’t necessarily have to dig out the whole clump, but you will need to remove the center and divide the clump into sections. Remember that warm-season and cool-season grasses will differ in this maintenance time, so divide the former in late winter and the latter early in fall. 

Start by watering the soil a day before you divide your ornamental grasses and prepare the new location or container for the clumps you’ll get. Then, cut the grasses back within 8 inches of ground level and sever the roots with a sharp spade. A useful tip is to cut a circle more extensive than the clump because it makes it easier to lift the clump out, and you can use a knife to cut the remaining roots. 


Option #2. Herbicides

If digging up proves to be ineffective and too much of a hassle, you can consider using herbicides to remove ornamental grasses. However, as with any chemicals, be careful with using herbicides if the grasses are close to other plants. If you want, you can also use pre-emergent herbicides to prevent grasses’ growth instead of directly using glyphosate sprays. 


How to use herbicides for ornamental grasses?

What type of herbicide should you use? Either liquid and granular herbicides will be useful and safe as long as you read the instructions and wear the appropriate safety gear. Remember to be wary of windy and warm days, and use greenhouse-safe products if you’re indoors. 

Cut down the grasses to be only around four inches tall for more straightforward applications. Check your spray as coarse droplets are better to prevent damaging other nearby plants, and remember that dilution might be necessary for some products. Lastly, guarantee that the day after application will be cool to avoid the evaporation of herbicides. 



If you’re growing decorative grasses, it’s ideal to know techniques in maintenance. More so, learning how to remove ornamental grasses will keep them looking neat and not bothering nearby plants. Start first by identifying your grass’s type and habit, then gauge if you need to dig up the grasses or use a herbicide.

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.
