What is Grass Burn or Scorch?
You may have experienced or heard of fertiliser burn or scorch on the grass. The term is descriptive rather than scientific. What actually happens is the fertiliser (being a salt) when in contact with the leaf of the grass absorbs moisture from it. This dries the leaf causing it to shrivel and therefore look like it’s been burned. Either way, the grass doesn’t like it!
High Grass Scorch Risk
This effect is increased when using combined grass ‘weed and feed’ fertilisers. By their nature they are a very fine granular or powder product to enable good contact of weedkiller and weed leaf. This fine quality also increases contact area with the grass leaves therefore increasing scorch potential. Secondly if the lawn fertiliser is ‘quick release’ then it is all ‘active’ and has even more burn potential.
Minimal Grass Scorch Risk
On the other hand the salts in controlled or slow release fertilisers are ‘locked up’ to a certain degree thus limiting the dangers. Secondly, fertilisers such as Lawnsmith® Fertilisers* are granules or pellets that will bounce or roll into the soil off the leaf thus limiting the amount of fertiliser contacting the grass leaf. This virtually eliminates burn or scorch potential.
In summary, all fertiliser has scorch potential with some doing it more readily than others. At Lawnsmith we have taken great care to balance our products so that the scorch risk is virtually zero as long as you apply when there is some ground or soil moisture. If there is no moisture, as in a drought, only organic fertilisers should be contemplated.
