Product Information

Each product works in a very specific way to halt the growth of weeds. These methods are detailed below: Preventing Photosynthesis 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 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. Roundup works best while you are applying it to the plants that are growing actively. Usually, this happens in the fall as plants store energy and in the springtime of the year when plants break dormancy. However, Roundup is effective throughout the season against plants. Also, it is pretty easier to look for the right application conditions throughout the summer as compared to fall or spring.

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. 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.

Is there an alternative?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.
