Chemical lawn. Previous company was treating the dark green spots with fungicide, and the seed heads with a weed killer.
Those “pests” are nothing more than the family dog peeing on the lawn, and blue grass going to seed.
Chemical guy gets fired, and organic guy gets hired.
And this is why it is important to understand, and being able to interpret the different symptoms associated with the turf. Chemical guys treat every single lawn the same way. Broad leaf control in the spring, followed by grub control, a few applications of chemical fertilizer, just to apply more grub control and pesticides in the Fall. If they encounter a problem and don’t know how to fix it, they will spray a fungicide, chemical fertilizer and a herbicide application, without even thinking what the real problem is. Weeds are messengers. They are telling you there is a problem with the soil. Organically we will fix the problem. Chemically you get rid off the symptom, and nothing gets accomplished.
In this particular case, we let the grass grow taller. We took a soil sample, and got the results back. The only thing needed was compost, some calcitic lime, and a couple of applications of organic fertilizer.
So, before you decide to apply any type of fertilizer, fungicide, compost, or any other product, please think if it is really needed to apply unnecessary products on your garden or lawn.
