If your lawn is small why not kill it with Roundup or equivalent and put in
a good low maintenance turf? I don't know of a sure way to kill some weeds
and not others. Your current lawn will look different during different
seasons since each weed has its own season. If you don't EVER want to water
or cut it then be prepared to live with what you have now. Turf is just as
environmentally friendly as clover but it does require some
maintenance;Don't worry about the bees...they will survive. If you pick a
turf variety that spreads it will choke out most of the weeds. You will have
to fertilize and lime your lawn occasionally but this seems better than
using weed killer.

We have a small yard that is green. Some of it is grass, some crabrass,
some weeds & some clover.

I like the grass and the clover, but I don't like the other stuff. Will
a pre-emergent kill the clover & all the other stuff?

Do pre-emergents have runoff problems or wildlife consequences?

Is that all I should do in spring?

Should we overseed now?

I really wouldn't mind if the lawn was all clover; it's the really short
kind with little white flowers, it attracts bumblebees, doesn't need
watering, fixes nitrogen and doesn't need mowing. What are the odds of
it taking over?

TIA for your patience.
