On the surface, daylilies seem to be pretty enough flowers in all of their vivid yellow and orange splendor. You might be shocked to learn that for many people, the appearance of daylilies in their garden rarely comes as an unpleasant surprise. The reason for this is obvious. They invade privacy.

Daylilies are a hazard to the other plants in your garden just by being there. Because of their infamously dense growth and twelve-inch-deep roots, they are known for displacing any nearby vegetation.

In essence, they indicate a desire to occupy the garden. Worst of all, they are obstinate and challenging to get rid of.

Yet, eradication is frequently the only choice. This raises the question of whether the cherished and enduringly practical household vinegar can handle the job. Read on.

Will Vinegar Kill Daylilies

Will vinegar kill daylilies? Vinegar when mixed with dishwashing soap and salt can kill daylilies. However, several variables, including their maturity, the depth of the roots, and the number of daylilies present at the application site, will determine whether or not they will all perish.

Vinegar may be counted upon to prevent the growth of any other undesirable garden life it comes into contact with. Because it is non-discriminatory and effective at destroying weeds.

Plants are obviously included in this. Read on to discover how to utilize this adaptable and affordable substance.

How to Make a Vinegar-Based Solution to Kill Daylilies

You’re prepared to get rid of those troublesome daylilies, and you intend to accomplish it with vinegar.

Making a batch of a traditional vinegar solution for weed control is your best option.

The components and procedure are listed below.

• Vinegar
• Dishwashing soap
• Salt
• And a spray bottle.

The fact that this mixture is entirely natural and non-toxic eliminates the need for gloves or any other additional safety measures, which is possibly its best feature.

How to Safely Use Vinegar to Kill Daylilies

Plants are harmed by vinegar when it comes into touch with them. This statement typically serves as a caution.

Fortunately, our goal in this situation is to harm the daylilies so that we can eventually kill them, which makes the entire process rather simple.

Once the vinegar solution has been prepared and placed in a spray bottle, the spray bottle should be set to an appropriate setting, meaning one that allows for adequate power and precision. Then, you’re ready to go.

Spray the daylilies liberally, covering their stems and blossoms.

However, take care not to splash the soil with your solution, especially if there are other plants there.

Your solution’s three components all provide a risk to the soil since they have the power to alter its pH, dry it out, and deplete its nutrients.

Yet, because they like to grow so closely together, daylilies inadvertently preserve your soil by being so close to one another. They accidentally help you.

How Long Does Vinegar Take To Kill Daylilies?

After 24 hours the daylilies are exposed to the vinegar, they usually start to wilt. Your current efforts might be sufficient if you’re fortunate enough. And that they haven’t already proliferated in large numbers in your garden.

To get the desired effects, you might need to repeat the process a few times if you’re working with a large number of daylilies, whether or not they are mature.

Just a quick peek at the daylilies will soon demonstrate how much more must be done. Respray them if they still seem healthy. Easy!

More Ways To Kill Daylilies

Overall, vinegar is a respectable remedy for invasive daylilies.

It doesn’t hurt to be aware of a few different strategies, though, as daylilies are highly tenacious and will resist most attempts at cultivation.

Most of the popular ones include:

• Using Herbicides and Weed killers
• Mow and Mulch
• Hand Weeding
• Plastic Barriers

1. Mulch 

Mulch might be your best option if you have the luxury of time. 

The area where the daylilies are growing must first be mowed. 

The mulch will then be applied. It should be sufficient to have about 12 inches of it. The mulch suppresses the daylilies while obstructing their ability to absorb sunlight. 

The daylilies just cannot flourish in such conditions and will finally perish, roots and all. 

The procedure will indeed take a long time—in some circumstances, an entire year! 

Once your initial layer finally starts to decompose and lose its effectiveness, you’ll probably need to apply the mulch a few times a year.

2. By Hand 

You could probably take out the daylilies invasion by hand if it isn’t too excessive. 

Simply don some gloves and get a handy spade to help out. Dig up the daylilies after that, making sure to get their rootballs. 

Along with killing the existing daylilies, this will also make it less likely for them to reappear. 

It’s crucial to dispose of the daylilies that have been pulled with additional caution. To prevent their growth in any way, put them in a bag and secure it with a tie. 

Of course, combining them with compost is not an option.

3. Weed Killer 

Daylilies can also be killed by spraying weed killer on them. It operates similarly to vinegar. 

Just spray the weedkiller on the daylilies, keeping the soil and any nearby plants out of the way. During two weeks, the daylilies will start to die and should be gone with a few touch-ups where necessary. 

Systemic weed killers are hazardous, in contrast to vinegar. Therefore you must be careful to keep any pets and young children away from the affected area.
