They're easy to apply and work well. Well, prevention is the best cure and there are several tactics you can use to keep weeds away.

It is effective at killing well-established weeds because it works from inside the weed itself. After being absorbed by the leaves and stalk of the weed, glyphosate spreads to the rest of the plant, including the roots. In recent years, it’s developed a reputation for being dangerous; however the jury is out on a definitive conclusion. Some studies have found it to be carcinogenic, whilst others consider it safe for humans to use as long as the instructions are followed. Glyphosate is also thought to negatively affect wildlife such as bees and aquatic life. It can stay in the soil for a long time as well. The formulation uses no harsh chemicals such as glyphosate or bleach making it ideal for use on most hard surfaces that means that the non-staining formula can be used to clear weeds and moss from patios, driveways, tarmac, concrete, sandstone and more. Organic and BiodegradableChoosing the right weed killer for the job is crucial. Here are some of the most common types of herbicides. We tested Dandelion Doom in an out-of-the-way lawn area that was moderately infested with clover, dandelion, wild violet, crabgrass, and a few other weeds. After marking a small test plot, we sprayed the weeds individually, without being especially careful about overspray. After 24 hours, we noticed discoloration of the dandelion, clover, and violets. After the third day, most of the broadleaf weeds appeared dead. The standout feature is how easily the product spreads. The bottle is designed with a convenient shaker cap: Just shake it over the intended area, add water, and you are done.
