Adequate fertilizer also is important, but keep in mind that more isn’t better. Although lack of nitrogen is a key factor behind outbreaks of dollar spot, excess nitrogen can encourage summer patch, brown patch, and pythium blight. The trick is to give lawns enough fertilizer to encourage good growth without over-doing it.
One way to do that is leaning toward slow-acting fertilizers that break down gradually and feed over a longer period of time, such as those in GreenView’s lineup of lawn fertilizers. Or sign up for a GreenView Annual Lawn Plan in which the right products for your lawn are shipped at the right time throughout the growing season.
What about bad outbreaks?
Lawn fungicides are available to slow the progression of lawn diseases, but they’re primarily effective at preventing outbreaks and their spread rather than curing diseases. Different ones are more effective than others, depending on exactly which disease you have, and they have to be applied correctly to work best.
That means researching to identify the cause of your patches and reading labels before applying any product – or calling in an expert. If dollar spot has infected your lawn, fertilizing with a high-nitrogen product will often fix that as opposed to using a fungicide.
