My grass is green. The grass is thick enough that I do not have to deal with broadleaf weeds. So my yard is free from from weed killer, pesticide and insecticide applications. Been doing it for the last 15 years.
I bet it would stay that way without the treatment.
You're not removing any...
1 c regular Coca Cola (no diet) (thatch control)
1 c ammonia (use lemon scented if you want insect control)
1 c dishwashing soap (use lemon if you want insect control)
1 c antiseptic mouthwash (anti fungal)
1 can cheap beer (enzymes stimulate growth)
1 c liquid fertilizer
To really benefit...
I called a local farm supply store and they recommended a Dr. Earth product
The Dr. Earth stuff would cost us $80. Yikes
Dr Earth is a high end "organic" product sold only in overpriced specialty stores.
When you ignore the sales hype and the "feel good" organic rhetoric, and ONLY look at...
No regular spreader will handle compost, and you'd need about a ton for your yard anyway.
Just use a good balanced pellitized fertilizer, and put it out the day before a good rain.
It won't hurt the chickens
