Removing the Yucca plant by digging helps eradicate it effectively. To begin this process, remove any plants growing near it. The digging process may otherwise cause them harm.

To dig the Yucca plants, you need to gather items, such as a saw or a small axe, pruning shears, shovels, and protective equipment, such as gloves and clothing.

Here are the steps you need to follow to dig Yucca plants out.

Cut Down to Stump

The first step involves cutting Yucca plants down to their stump. You can remove the plant’s shoots, branches, and stems, leaving behind the main stump.

When you are left with the stump only, you can estimate the hole size you need to dig, depending on how extensive the root system is. Once you reach the stump level, you can cut it off using an axe or saw.

Dig a Hole

Next, you need to dig a hole around the stump of the Yucca plant. The hole must be at least 3 feet around the stump so that you can ensure the whole root system comes within the area.

It would help if you marked the area to be dug with a circle to make the process of digging easier and more reliable.

Dig Deeper Into the Hole

Now you need to dig 3 to 4 feet deeper in the area marked for digging around the stump. You can use a shovel to do so. Digging a deeper hole makes it easy to remove the root system.

You must go on removing any roots or plant parts you encounter while digging if it is long enough. It would help if you dug deeper for short ones to pull them out quickly.

Apply Stump killer

After removing the roots, you must check for any other roots in the soil and pull them out. Now you can apply a stump killer to the soil to kill any roots that might remain behind.

Let it Dry

Now you must leave the hole open for 2 to 3 weeks. It is necessary to dry the soil and dry out any roots due to long exposure to the sun. It kills the roots hidden deep into the soil and gives you Yucca-free soil.

Check for New Growth

Once you dig out the plant, you cannot just sit back. It will only allow the Yucca plants to emerge from their roots within one month. Hence, it would help if you kept inspecting the area for new growth of shoots after filling the hole. If you find any new growth, you must immediately pull it off the ground.

2. Apply Herbicides

Herbicide application may be your last option for killing Yucca plants. It works most of the time and prevents any further growth of Yucca plants in your lawn. However, applying the right herbicide mix is the key to getting rid of Yucca.

Non-selective herbicides targeting the root system of Yucca plants are considered preferable over traditional weed killers. To apply herbicides, you need to gather the items you used for digging in addition to an effective herbicide mix.

Here are the steps you need to follow for herbicide application on Yucca plants.

Choose the Right Time

Herbicide application works best when you do it at the right time of the year. Hence, you must first choose the perfect day for herbicide application. Applying herbicides during spring, early summer, or fall is preferable. It is because herbicides work best during cool temperature ranges.

Cut Down to Stump

Herbicides work best when you apply them closest to the root system. It is possible only when you cut down the plant to the stump level. The best time to cut the plant is during summer or spring when it is still growing.

You can use shears to remove all the branches, shoots, and stems and leave behind only the stump.

Prepare the Herbicide Mix

Once you are done with the cutting, it is time to prepare the herbicide. It is the most crucial step of the process. To prepare the herbicide, you must pour the herbicide first into a container, followed by vegetable oil or diesel fuel.

Usually, 19 ounces of herbicide with 128 ounces of vegetable oil or fuel works best. You can then vigorously stir the mixture for 15 seconds and pour it into a sprayer using a funnel.

You must wear protective clothing while handling the herbicide and the right equipment to transfer and spray it.

Spray the Mix on the Stump

Now it is time to spray the herbicide on it. But before spraying, you must ensure the stump is dry and there is no rainfall. You must wait for the stump to dry if it is not.

It is necessary to shake the mixture before applying it to the stump. It is enough to spray the stump for 2 seconds only. But it would help if you aimed correctly on the stump and not harm other plants in the vicinity of it.

Check for New Growth

After applying the herbicide, you must keep checking the area for new growth, as it might reappear. You must pull out any new shoots appearing immediately and spray the area with the herbicide mixture again. It might take around two months before you stop finding any new shoots of the Yucca plant.

Hence, in this way, you can use the two methods to remove Yucca plants from your yard permanently.
