Common Signs of Lawn Fungus Diseases
- Spots and patches
- Underdeveloped growth
- Bleached or light colored turf
- Shredded or curled grass blades
- Circular lesions on the blades
- Dark growth at the base/thatch line
In general, the damage from a fungus will be circular. Correctly identifying the damage is crucial. For if the damage is actually grubs, treating them with fungicide won’t work, duh! Fungi that damage the lawns are parasitic and steal nutrients from grass, which causes it to decline, turn colors or in some cases die. When a fungal spore encounters a host in the right environmental conditions think: pathogen + environment + host = disease
Common Lawn Fungus Diseases
Changing your lawn care habits might reduce your risk of fungi problems. A healthy lawn has a really good chance of pulling through a fungal infection, but that is up to you!
- Water your grass regularly, but don’t water it too much because waterlogged grass invites fungi. Don’t set your irrigation and not monitor it.
- Dry grass can also makes your lawn more susceptible.
- A one time, nitrogen-based fertilizer applied in the fall supplies your grass with the nutrients it needs to flourish.
- When you mow, don’t remove more than one-third of the length of the blades of grass at a time. A healthy length for grass (from the thatchline) is 3 inches tall.
Generally, a homeowner doesn’t have many choices in the self-help isle of the Big Depot. You also don’t go to the store until you notice there is a fungus among-us in your lawn. There are many products, however most home-use products will cure most fungi. ALWAYS read the labels thoroughly.
The first thing you must do is to cure or the CURATIVE treatment. Which, in general, is either a stronger mixture, applied more often or both than the PREVENTATIVE. Be aware, you will need to apply this curatively, every 3 weeks, preventatively, every 4-5 weeks.
Organically, I’ve heard of putting corn meal on the lawn. I’ve got no experience using this. Has anyone tried this??
