Question

how is weeding done ?

Answer 1

Pull weeds while you’re talking on the phone- better yet, while you’re on hold.  Yesterday I managed to get the above bed completely weeded, plus another one (3x50) while waiting to speak to a real human on the phone.  
 Go for a walk or a run outside; when you’re, do your stretches next to something that needs weeded.  Hey, if you’ve gotta bend over anyway, you might as well make your hands useful!
Pinch little weeds out as soon as you can identify them.  This is a bit of a change from what I used to do, pulling them out as soon as they appeared.  Years ago a wise neighbor pointed out all the volunteer perennials in her flower beds… and changed forever how I weed.  Instead of indiscriminately pulling every seedling in the bed, now I only pull when I know what it is.  This isn’t as hard as it seems; 90% of the weeds in my yard are one of the same nine or ten plants.  Figure out what your common weeds are, and learn to identify them as small as possible.  If you don’t know what it is yet, let it grow until you do.  There are only a few plants that will spread horribly if you wait- and you’ll be able to identify those pretty quickly.  Generally speaking, most plants spread only once they’ve flowered and set seeds.  You’ll get a lot of pleasant surprises by weeding this way; right now close to 1/3 of the flowers in my yard are volunteers!  I’ve even had bushes and trees free this way.
Use weeding time as one-on-one time with a child. Let them tell you about their day, or their new project, or the book they've been reading, or whatever else.  I have great memories of fixing barb-wire fences on our farm because of this- it meant time to talk with my dad.
Spend time in your yard, in all parts of the yard.  You’ll better notice what needs done.  And you’ll enjoy it much more than from indoors!  Another neighbor told me to have a place to sit somewhere on each side of the house.  Sit and read, or watch the kids, watch the sky, watch the bugs, whatever brings you joy.  Gather a bunch of fresh flowers for a vase every couple days.  Enjoy those efforts!
