Okay, time for a pop quiz: Take a look at the picture above. What do you think it is?
A. The surface of a distant, arid planet
B. A dry, tasteless diet cracker
C. A piece of ’70s-era bathroom linoleum
D. Oxidation on a concrete driveway caused by haphazardly applied fertilizer
The correct answer, is of, course: “D.” (After all, this is a lawn care blog.) What you may not be aware of is that the very ingredients that keep your grass and plants healthy can be detrimental to concrete and other hardscape surfaces in your yard. Many fertilizers contain iron. Iron oxidizes — but rust doesn’t have to be your destiny.
When applying fertilizer, it’s paramount to ensure that all surfaces the product comes in contact with — other than the intended soil and flora — are properly washed down to prevent oxidation from occurring. It’s not rocket science. If you want to keep your driveway from looking like the surface of the moon, all it takes is some H2O and a well-aimed hose.Share
