When it comes to defending your garden from weeds, the best defense is an offense. Many garden owners use herbicides as weed killers to maintain the beauty of their garden. However, they have no idea what harmful chemicals they bring near their homes by doing so.

If you are environmentally conscious, you have plenty of options to choose from. Organic herbicides disappear in a matter of hours after they have done their job. Additionally, they do not change the soil PH, nor do they pollute the water. The only downside of organic weed killers is that they require multiple applications, but the extra maintenance is more than worth it.

An Eco-friendly Alternative: Organic Weed Killers

There are quite a few benefits that come with organic weed killers. We created a shortlist that will guide you through how these eco-friendly weed killers work.

Fact One: Most Organic Weed Killers Kill any Type of Weed

Most herbicides are created to destroy only a few types of plants. However, this is not the case with organic weed killers. Although when you use an organic alternative you need to spray the soil multiple times, the solution kills almost every type of weed it comes in contact with.

These types of organic herbicides should be used only in areas where you want to get rid of vegetation completely.

Fact Two: Most Organic Weed Killers are Dependent on Weather

Always apply weed killers when it is sunny outside. Rain can wash away the product, diminishing the effects of the solution. Weed killers that do not come in liquid form work better even if they are used in a humid and rainy climate.

Fact Three: Most Organic Weed Killers are Safer Than Non-Organic

Most organic herbicides can be used without special permission because their active ingredients are safe for humans too. However, there are some products that use dangerous chemicals.

Check the label for “all organic ingredients” before you buy. Some companies combine both harmful and organic weed killers to increase the strength of their solution. The safest organic weed killers won’t change the PH of the soil.

Look on the bottle for messages such as “danger” or “warning”. Some organic weed killers are safe for lawns but should not be used on food crops. Check the label to find out more about how the herbicide should be used.
