How To Get Rid of Weeds in Flower Beds Without Killing Flowers?

For centuries, farmers and gardeners have been applying mulches to limit unwanted weeds production, enhance the productivity of crops, moisturize soil, minimize water intake, and maintain the correct temperature of the soil.

In addition to the primary role of preventing weeds, mulching also has surprising secondary benefits. The secondary roles of mulching are beneficial in the productivity of the desired flowers and vegetables. Making mulch beds blocks a sufficient amount of sunlight for weed germination.

Mulching also creates the right environment to increase the growth rate of the desired crops. Although mulch beds are most effective in reducing weed production, it doesn’t necessarily guarantee a successful weed-free garden.

You may see weeds growing up in mulch beds if not taken care of. In small settings, hand pulling or hoeing can be worthwhile in removing weeds.

In big settings, the hard labor of hoeing or hand pulling may not be beneficial. Generally, removing weeds when they have just sprouted out of the soil is highly advisable. Because if weeds mature, their removal can damage the roots of your desired flowers.

The following constructive ways can guarantee you successful weed-free mulch beds.

Add Herbicides In Mulch Beds

Mulches alone may show quality results in the prevention of weed production, but adding pre-emergent herbicides can maximize the effectiveness of mulching in weed prevention.

When making mulch beds for flowers, add a pre-emergent herbicide. It will enhance the functionality of mulches by killing weed seeds. To increase the functionality of mulches, remove existing weeds around the area where you want to build flower beds.

Either use hoeing tools or manually remove the existing weeds with your hands. Then add pre-emergent herbicides evenly in the layers of mulch.

Unfortunately, such herbicides can not help much with preventing already-grown weeds.

How To Get Rid of Weeds in Flower Beds Naturally?

Using natural solutions is always better because the hoeing of matured weeds may damage your flowers’ roots. Eco-friendly ways to eliminate weeds can significantly reduce the efforts and labor costs required to remove weeds successfully.

We have three natural weed killers that are not only inexpensive but can also be easily found around your kitchen.

These natural weed killers are also incredibly effective in removing or killing weed seeds and matured weeds.


The acidic properties of vinegar can amazingly kill unwanted wild weeds. Typically white vinegar that can be easily found in the house contains 4% to 7% acetic acid. To get more constructive results, you can also find white vinegar specially made for agricultural purposes.

White vinegar for agriculture purposes contains up to 20% acetic acid and kills weeds more effectively. However such vinegar is strictly forbidden for human consumption.

Pour the white vinegar into the spray bottle or directly pour the vinegar on the unwanted wild weeds. A little amount of vinegar will not harm your flower beds.

But to be extra cautious, carefully spray or pour vinegar on the weeds.

Baking Soda

Another excellent natural solution to kill weeds in your flower beds is baking soda. Baking soda (also known as Sodium bicarbonate) is made by combining oxygen, sodium, hydrogen, and carbon elements.

Baking soda’s alkalinity provides multiple benefits to gardens. Among them, one is weed killing. To kill weeds, directly pour one or two tablespoons of baking soda to cover the roots and foliage thoroughly.

Cover the entire weed with a bunch of baking soda to get quicker results. The alkaline properties of baking soda will slowly but surely remove the annoying weeds.

These unique alkaline properties of baking soda will also minimize the chances of powdery mildew during the spring.


Like vinegar and baking soda, borax is amazingly useful in killing weeds in flower beds. Mix 10 ounces of borax with two and a half gallons of water to kill these unwanted intruders.

Pour it into the spray bottle and thoroughly spray it on the weeds’ leaves and roots. Other than killing weeds, borax can also enhance plant growth and yield. When applying on the weeds, follow the general instructions of mixing 10 ounces with two and a half gallons of water.

Too much borax can harm your flower beds and may even kill the flowers.

Why Not Use Salt in Your Flower Beds?

Although several blogs suggest table salt usage for weed killing, it can harm your flowers. According to studies, salt can significantly damage soil conditions for proper flower growth. The regular use of salt can disrupt the water balance of the soil and affect the flowers’ growth.

The use of salt for weed killing can be sufficient in small flower beds. Regular watering can easily control salt damage in small flower beds.

However salt in large flower beds can profoundly damage the soil water balance and moisture.

Can You Get Rid of Weeds Immediately?

Unfortunately, as much as you would have wanted, you won’t be able to eradicate weeds from mulch beds right away; it takes time and work.

As mentioned in this article, herbicides or other weed killers work best to eliminate weeds. A granular pre-emergent helps prevent weeds from sprouting further and preserves a spotless landscape.

If you’re wondering what kind of mulch to eliminate weeds, low-quality mulch is the most excellent choice for weed control. Mulch works against weeds by blocking sunlight from reaching the soil’s surface.

Unfortunately, this doesn’t always work as sunlight can find its way through the mulch layer leading to weeds’ growth. The more mulch you add to the bed, the better since it provides better cover from the sun. And when you plant your bed, landscaping cloth also works wonders to keep weeds out.

This straightforward procedure uses high-quality fabric beds to prevent weeds for over 5 years.

How does it work?

The landscaping cloth can prohibit sunlight and keep the weeds from growing.

Final Words

In addition to weed killing, mulching is also used to enhance the productivity of crops, moisturize soil, minimize water intake, and maintain the correct temperature of the soil.

But mulch beds need your occasional attention and care. Replenish mulch layers when you find the layers thinner than 3 inches. Do not make thicker mulch layers more than 3 inches, as it can restrict oxygen intake in the soil.

A little care will pay higher aesthetic and growth results for your flower beds.
