It is always around May that attention is focused back on our beloved Dandelions and all the hard work they put making our lovely lawns look a right mess. May is the beginning of the Dandelion season and swift action must be take to avoid these critters from reproducing.
Lawn weed killer is the most effective way of controlling lawn weeds such as Dandelions, Plantain and Creeping Buttercup. Alternatives to using a Lawn weed killer is to spot weed each weed using a general weed killer such as Roundup or Rambo. Another way to control weeds on your lawn is to go around a dig them up individually using a garden spade or the other handy weed tools such as the Grandpa’s weeder. These above methods, while effective are somewhat time consuming and not very applicable over large areas.
Most lawn weed killers, such as Dicophar come in a concentrated liquid form and are diluted in water before application. The Dilution rate for Dicophar is 100ml in 10 litres of water. That’s equivalent to 100 litres of diluted mix to every 1 ltr of concentrated Dicophar lawn weed killer. This dilution rate is known as a 1% mix.
Other weed killers may vary and you should always read the label before using and applying the product.
Application rates can vary but in general to kill weeds on an average garden lawn an application rate to 10 ltrs of diluted lawn weed killer to every 100m2 of lawn area is adequate.
There are many other lawn weed killers such as Doff, Resolva, weedol and Hytrol but Dicophar offers the best value when comparing cost per m2 coverage.
Dilute lawn weed killer is best applied to your lawns using a large knapsack sprayer. Anything that is 10 ltrs or larger would suffice while anything smaller would require a continuous need to refill the sprayer.
When spraying your weeds you should walk at a steady pace and visually note what area you have covered and what areas you still need to cover. A walking pace of around 1 metre per second with the sprayer on full blast covering a spread to 1m at a time would give a good application and work to around 10 litres to every 100m2.
Again, like any weed killer only apply in dry conditions, on a calm day, during the growing season. Results can be seen quite fast but weeds take about two weeks to die. If your lawn was full of dandelions it will soon be full of small holes where the dandelions once sat.
