One of the most effective methods for naturally killing weeds in flower beds is through spreading mulch. Applying a layer of organic mulch, such as wood chips or straw, can suppress weed growth by blocking sunlight.

During our experiments, we also found that mulching helps retain moisture, which benefits your flowers while keeping unwanted plants and flowering weeds at bay.
Mulching for Weed Control
Boiling Water Technique
A simple yet powerful natural weed killer is boiling water. Pouring boiling water directly onto the weeds causes them to wilt and die quickly. This method is especially useful for targeting weeds growing in cracks or along the edges of flower beds. Be cautious to avoid your flowers, as boiling water can harm them too, but keep in mind that there are also weeds that look like grass.
Vinegar-Based Solutions
Vinegar weed killing is very effective for applying this method you need to create a solution with vinegar, water, and a dash of dish soap that can effectively kill weeds.
The acetic acid in vinegar desiccates the weeds, causing them to die. Spray this mixture carefully onto the weeds, avoiding contact with your flowers. Regular kitchen vinegar works, but higher acetic acid concentrations are more effective.
Hand Weeding
Hand weeding is a classic, environmentally friendly approach to get rid of garden plants, particularly weeds. Regularly removing weeds by hand ensures that your flower beds remain unharmed.
This method allows for precision and control, ensuring that only the unwanted plants are removed. Hand weeding is labor-intensive but offers a chance to closely monitor the health of both your flowers and soil.

Cornmeal as a Pre-Emergent
Cornmeal acts as a natural pre-emergent herbicide. Sprinkling cornmeal over your flower bed inhibits weed seed germination. It's a preventative measure, so it's most effective before weed seeds begin to sprout. Cornmeal is safe for your flowers and adds organic matter to the soil as it decomposes.
You can completely prevent weeds from growing in your garden by implementing ground covers.
Planting Ground Covers
Similar to using cornmeal, utilizing ground covers in flower beds can naturally suppress weeds. Ground covers, like creeping thyme or sedum, form a dense mat that blocks weeds from receiving sunlight and space to grow. This method not only controls weeds but also adds diversity and beauty to your garden. But they can also make your garden feel more unnatural.
