If I need to fertilize an area, I use non-burning garden fertilizer, while is a mix of Milorganite and chemical. The Miloganite acts as a slow release that the plants can uptake, and the chemical give it a kick so that the grass will grow quickly and convert everything to biomass.

Ideally I prefer things like chicken meal and other mulching type fertilizers (pure milorganite), but notice no real effect since they are so slow-acting. The garden fertilizer is a balance of both, and seems to have a lasting impact when mulching the clippings back in.

My biggest gripe with chemical fertilizers (oil-derived) is only a small portion is usually taken up by the plants, the rest is washed away or percolates down into the water table. This all runs off into creeks and rivers. Up here in the Great Lakes, this causes huge BG algae blooms and other toxic algae that kill migrating birds that happen to eat the fish in it. Last year hundreds (thousands) of loons where killed, one of my favorite birds, on Lake Ontario for what? A green lawn? The shame.

I have no problem using fertilizers conservatively on crops, it is necessary, but lawns give me a heartache for the harm they do. We mash up all of the critters with mower blades and chemical the ecosystem to do as the Romans do.

IMHO be conservative, don't expect a green carpet, enjoy the diversity of the plants that grow in it if they are not poisonous. We still pick native strawberries out of our lawn in early June, and they are fantastic!

Do what you want, but please consider the consequences also. There are other things you can do.


I mow this about 3x a year, mostly to knock out the more woody plants in the early summer to give low-crowned plants a leg up. I use a weed-whacker as to not mash up the frogs and insects too much.

Well this?
What it looks like when I am too lazy to mow. Note the diversity:

You can see the transition from slightly fertilized lawn to "field" that is only mowed in the late fall to keep the brush out. That corner is FULL of life, and the deer love to bed in it. Never mind the largely neglected pond garden on the right. However, that cranked out THOUSANDS of cute little tree frogs this year.

The dandelions, most here fight them tooth and nail. It is pointless and futile. I embrace then, as the deep roots capture fertilizer the grass misses, and I find them pretty in the spring:

Lastly is my gripe of people mowing every last corner of a large lot. Let some portion go each year to give wildlife a home! You can rotate the area you let go wild, trace out cool patterns and paths if desired, plant some wildflowers, etc. Trust me, your property experience improves with a little wild added in (if you are not doing that already!)

Well, that is my stance on lawns. I hate their necessity to keep bugs away from the house and have a place to kick balls around with the kid and dog.
