All in one weed n feed products don't perform the miracle as shown on TV. Just get that out of your mind. If you want to fertilize, us a pure fertilizer. If you want to kill weeds, get the right kind of liquid herbicide and spot spray only the weeds. There are two kinds of weeds: broadleaf weeds and grassy weeds. Grassy are hard to kill in grass because the grassy weed killers kill grass, too. I suggest you work on the broadleaf weeds with Weed B Gone spray and see how it looks in a month or so.

What you have now is kind of a cool wildflower garden. I have part of my 1 acres in "wild flowers" too. Neighbors call them weeds from May through March, but this time of year, it's really cool.

You must answer a few questions before we can help.

Where do you live? Name the city or county, not your zone.

Are you willing to mow?

Is shade much of an issue on your 1.4 acres?

Don't rush this. Many people do and find out they wasted their time and also wasted future time which will be needed to undo the damage they did.

Thanks for the reply.
