Baking Soda as a Homemade Weed Killer—Here's How to Use It Successfully

Baking soda can be used as an effective and simple solution for destroying weeds in some situations. This home household item is strong enough to destroy smaller types of weeds. It also has the added benefit of keeping powdery mildew at bay—a fungal disease that is often present on prized landscape plants like rose bushes and lilac shrubs.

Using baking soda to treat weeds is simple, either by applying it straight out of the box or mixing it with a solution to spray over areas you desire to treat.

Understand why baking soda kills weeds, how to use it properly, and what its limitations may be.

Why Baking Soda Kills Weeds

Baking soda's weed-killing properties are partially due to one of its largest ingredients: salt. Salt dehydrates plants if used in sufficient quantities, and eventually kills them by preventing water intake.

If you're sure that you want to kill a weed, drying it out is a suitable option. By drying out the plant completely, it ceases to be able to take up water, effectively eradicating it.

Even though larger plants like shrubs require larger doses of sodium bicarbonate to realize this, caution must be exercised when using baking soda on shrub leaves, particularly when controlling powdery mildew. To create a successful solution for such applications, one should mix one teaspoon of baking soda with one cup of water.

How to Dispose of Weeds with Baking Soda

Baking soda may be applied to weeds in two basic manners:

1. The most convenient process is to simply sprinkle baking soda right out of the box onto weeds (about one teaspoon per weed). To facilitate the adhesion of baking soda, moisten the leaves first so that the baking soda adheres well to the leaves.

2. Alternatively—and better—make a solution by combining baking soda and water. Transfer the solution to a spray bottle and spray directly onto your weeds. This conserves wastage and avoids the drawback of baking soda blowing away while applying, as is the case with the direct-sprinkle method.

Regardless of your chosen technique, always apply baking soda on a sunny day. Rain can wash away your treatment before it has a chance to work its magic. If opting for the spray solution method, mix and apply carefully for the best results.

Naturally, five additional tips to eliminate weeds are, aside from baking powder, there are many other ways to kill weeds naturally.

• Vinegar: Vinegar is a natural herbicide as well. Use vinegar to obtain the best outcomes with high acetic acid.
• With boiling water: This is the cheapest way to kill weeds naturally naturally. However, never forget that it's not selective.
• Suffocation: Black plastic suffocates weeds with plans, etc. It works best with landscape areas that have high weed density and monoculture designs. For example, a plan to suffocate the Japanese knot.
• Hand Powder Weed: It is a very obvious one and is easy to forget. Most gardeners enjoy getting their hands in the soil and in contact with the plants, even though it's a weed.
• Salt Usage: Rather than employing the baking powder, salt is also employed to eliminate weeds (as it is a salt in baking powder, therefore the herbicides will work). Salt is cheaper, and so this might be a smarter alternative.
