The modern selective weed killers have become extremely popular and old-fashioned lawn sand is now often ignored in the weed killer programme. It is true that the active ingredient (ferrous sulphate) can scorch fine grasses when carelessly applied and it only kills the top growth and not the roots but a wide variety of weeds, including moss, are kept in check. There is also the added bonus from its other ingredient (ammonium sulphate), which gives the lawn a rich green colour and helps to maintain the acidic condition of the soil, which is so vital
The way to use it: Soil must be moist at the time of treatment. Do not use during a drought. Use on a sunny morning with the prospect of fine weather. Even application by hand or applicator is vital. Do not overdose, but the lawn can be treated several times during the season.
after using lawn sand
Immediately following treatment: Do not mow or walk on the lawn until rain has fallen or until it has been watered.
2 days later: Thoroughly water the lawn if rain has not fallen since application.
3 weeks later: Rake up dead undergrowth. If clumps of weeds are still present, use a selective weed killer or apply a further dressing of Lawn Sand.
