Black Medic is a sign of low nitrogen
I once moved to a house that was infested with both bindweed and thistle. Imagine my yard as a big rectangle. I started pulling weeds on the left and stopped about ten percent of the way across. A few days later, I started at the left again and picked out anything that cropped up in the last few days and then made a little progresss into the rest of the rectangle. Each brief weeding trip gets me another 5% of new territory. The important thing is to always weed the area you already weeded first. If I didn’t do it this way, then the weed would recover in the first section while I was attacking another section.
Dandelions are a sign of alkaline soil. Refer to the pH stuff above. The above methods will prevent dandelions from propogating. Since dandelions live about five years, the mature dandelions will struggle with the tall, thick turf and die off in two to three years. I now think that a few dandelions poking up once in a while are kinda nice and I leave them alone.
Black Medic is a sign of low nitrogen soil. Refer to fertilizing above. The above methods will keep black medic in check. You will occassionally see a little once in a while, but it is kinda pretty when it isn’t taking over your lawn. This stuff is sometimes called “yellow clover”. When it’s taking over, it will choke out grass and make flat mats about a foot in diameter. I found a litte in my current lawn and it was a single tiny strand with little yellow flowers.
