LERAVA

Seed and iron, by the square metre

LERAVA appears on two of the treatment shelves here.

The grass seed is an overseeding mixture sold with a coverage figure. On that shelf the coverage on the front is only true at the rate on the back, and the two rates — new lawn and overseeding — differ by roughly a factor of two. This site prints the rate rather than the area claim, because the rate is the number that transfers to your lawn.

The moss product is iron sulphate, which is worth naming rather than describing. It blackens moss within days, it is also an iron feed, and it stains: paving, a path edge, a pair of boots. The marks are rust and they go into a porous surface rather than sitting on it. Sweeping hard surfaces before watering in is the whole of the precaution and it takes two minutes.

What any particular product requires by way of dose, protective equipment and permitted use is on its label, which is a legal document. This site prints what the maker states about coverage and points at the label for the rest.

The live figure beside a product went and asked the shop for it the moment this page opened; any amount written into the text has not moved since the sentence was drafted, and it is the first of the two that counts.
