This is a continuous process so consider opting for a weed killer that prevents them from ever appearing in the first place. Not all weed killers are the same. Some are designed to work on a specific species of weed whereas some are considered to be more of a general purpose weed killer. There are even differences in how each product neutralises weeds as well as a vast difference in the ingredients used to complete the task.

Other (residual) weed killers are applied to the soil which then prevent species of weeds from germinating and ever appearing. Systemic weed killers: Systemic weed killers are usually taken in through the foliage, and from there spread through the rest of the plant to its roots. This gives the weed killer a decent fighting chance of killing off the whole plant. They usually take longer to act, but are effective against the plants they’re designed to kill. What’s more, they don’t hang around in the soil afterward, which means it’s safe to plant again. There are also some products on the market referred to as “natural” weed killers. Corn gluten is one ingredient which you’ll find used in some selective, pre-emergent weed killers. Corn naturally secretes a chemical that kills other nearby plants. That chemical is found in significant concentrations in corn gluten. However, it is generally not effective against common lawn grasses which is what makes it a great option for pre-emergent weed control in lawns. Plants have hormones too, and these chemical hormones are linked to natural growth. Some weed killers contain plant hormones, some natural and some synthetic such as 2,4-D (Trimec). When these products are applied to the plant, the hormone is absorbed and confuses the plant’s own growth system. This leads to growth deformities before eventual death. Additional Information

These conditions do not affect the herbicide’s effectiveness but restrict the unintended transfer of its chemicals to your desired plants that surround the unwanted one. As glyphosate kills all the plants, chemicals washed off the plant’s leaves by rain or blown in the wind can transfer to other garden plants.

Some weed killers prevent a plant from being able to produce these necessary proteins which eventually causes the plant to die. Glyphosate, the active ingredient and chemical you’ll find in Roundup weed killer works in this way. Manipulating Hormones

Residual weed killers: These weed killers target the soil and kill weeds as they’re absorbed through the roots. They’re effective and long-lasting, but their awesome power comes at a price, hanging around in your garden and affecting the soil quality and future plant growth. According to the label, they recommend using it on dry, warm days. If it's about to rain, don't worry - all of the products should dry in 30 minutes to 3 hours - some even faster.Gardeners can apply herbicides like Roundup when the air temperature remains between 60 degrees and 85 degrees. Fall and spring seasons are too cool for effective herbicide application. You should avoid windy weather conditions and also when you are expecting rain while applying the herbicide. Fertilising your garden will keep it healthy and increase the strength of your plants and flowers. This will make it much harder for invasive weeds to take hold as there’ll be a dense root system preventing them from germinating properly.
