Using lawn fertilisers properly
How Does Fertiliser Burn Lawns
Fertilising lawns is vital to providing the turf with so many nutrients which may not be readily available to the lawn at its soil source, and fertilising adds tremendous benefit to feeding our lawns, and thereby improving the overall health and beauty of the lawn as well.
Though with fertilising also comes a few risks which can be easily avoided with careful application of these lawn care products. And one of those risks is fertilisers burning lawns.
The Nitrogen in lawn fertiliser can burn the leaves of lawns, turning the lawn yellow, brown or black. Nitrogen is the same nutrient that causes the spots created from dogs urine on lawns.
So we look at how to greatly reduce that risk.
Water Lawns After Fertiliser Application
All lawn fertilisers must be watered in within a reasonable time period after fertiliser has been applied. The time frame for watering is usually dependant on the heat of the day. The hotter the day, the sooner fertilisers must be watered in to prevent fertiliser from burning the lawn.
On cooler days, the time can be extended. However, it is never a good idea to leave fertilisers on the lawn for too long without fully watering the fertilisers into the turf.
The maximum amount of time allowable is to always plan on watering fertilisers immediately or within hours of application in warmer weather, and within a day in cooler weather.
Hot Summer Days
During any times when the days are especially hot, it is always best practice to never apply fertilisers at all. The increased risk of damage to the lawn from fertilisers is just not worth it.
So if the days are hot, then its best to leave the lawn fertilising for a cooler day, and avoid any risk of lawn damage completely.
