The cardboard mulch idea can be used in small areas. However, it will
not eliminate certain seeds that can survive for years in the ground,
such as morning glory.

if i'm using an area where the soil will be disturbed
after eliminating a hard to get rid of weed, i have what
is called a stirrup hoe which quickly kills seedlings
before they can get well established again.

if the area isn't disturbed again the 2nd and 3rd year
after this method is used the seeds likely won't sprout
again if the mulch is deep enough, but not all seeds are
the same. it depends a lot upon the plant. morning
glory seeds are a pain in the butt for sure. i no longer
let them grow anywhere on our land if i can see them.
