Lawn sand is a combined weedkiller, moss killer for lawns and lawn fertiliser - though usually sold as a moss treatment. It consists of ammonium sulphate, iron sulphate and fine sand. It should be applied between April and September, in dry conditions, but preferably when rain is expected within a couple of days.
Moss Killer Lawn Sand
Follow the application instructions on the packet, but do not exceed the stated application rate otherwise the grass may be killed - as well as weeds and moss. Annual use will also keep worms, and therefore worm casts off the lawn.
Lawn sand can be bought at most large garden centres together with the smaller nursery type centres. It is not the most popular of lines to stock, so difficulty may be experienced in finding a lawn sand supplier in your area.It maybe in the section of Moss Killer for Lawns.
Because of the high weight to value ratio, it is not normally available online. Where lawn sand is available online, then expect to pay a premium price for either the product, or the carriage costs.
