eradicating Sasta (Alaskan) daisies and wild morning glories
I have a space in front of my house 3' by 50' that I planted these daisies about 25 years ago. They are not attractive anymore. Right now I am trying to pull out all the roots. But I hear they are pretty intractable. Any suggestions? I am not opposed to using Roundup.
This time of year digging is one way to remove all plants and roots. The cleaner, the less plants to regrow. Morning glory unfortunately has deep roots.
People have had good success with covering the area with three layers of cardboard then covering it with 8 inches of mulch.
In the spring, re-dig again to find missing roots or wait until the daisy or morning glory poke out of the soil, then spray with Roundup.
If the area can be "fallowed' or left alone, covering the area with an old carpet will reduce weed growth.
