Hi

A granular weed and feed should work , what I tend to do is stomp on the plant first to crush the leaves a little and then sprinkle the granules on but a bit more than what they recommend.

Try Verdone 2 - I think it might have changed its name to Weedol LAWN weedkiller (unhelpful, because Weedol make a range of weedkillers not suitable for use on lawns, so the lawn bit in the name is critical). It's a liquid you mix in a can and apply as instructed, and its much more effective than the combined lawn weed and feed granular treatments.

I simply just mow the grass (along with the weeds). This causes the grass to thicken up and choke out the weeds.

Doesn't work for me Bathgate! My 'lawn' is more weed that grass so will have to try the lawn weedkiller and see if I can end up with grass! Don't hold out a lot of hope as one side is all the invasive, deeply rooted and creeping Potentilla reptans! So I will be interested in following this question.

Oh dear Honeysuckle - the rule for lawns is, if its more than 50% weed, take it all up, dig out the weeds, and returf. Most of us don't, of course... try the Verdone or Weedol or whatever its called now.

Snap Honeysuckle - only mine is silverweed...

Honeysuckle: You can't mow the weeds and expect them to magically turn into a nice lawn. My advice was for a lawn with a few daisies popping up. You have an entirely different question altogether. Even if you pull up every single weed, you'll still have thousands of latent seeds ready to take over. After clearing the land, use a blow torch to cook all the seeds. Turn over the earth again and 2nd application with blow torch. Make the earth glow red hot like Hawaii's Mt. Kilauea. After the Earth cools, apply some rich dark humus compost & returf.

I will throw another spanner into the equation. Why not live with a few daisies and weeds. Weedkillers and chemicals are so bad for wildlife. There is also a 'say no to the mow' challenge going to try and encourage bees etc.
I have more clover and other creeping weeds than grass in my 'lawn area' but it stays lovely and green even when we have a dry spell of weather.
This year I found mining bees making their nests in the lawn and was delighted. I have also left a patch unmowed and have discovered a bee orchid! The bees love the flowering clover. Sparrows have been coming down nibbling. Much more interesting than pristine mown blades of grass!

It all comes down to personal preference.

Numbersfarm - in principle, I agree, to an extent, but it rather depends why you have a lawn in the first place, because where there are a few daisies and other weeds, there will soon be many more - flat foliage plants like daisies are not killed by mowing. You might have a large garden with plenty of bee friendly plants and the lawn is simply the 'carpet' against which the plants are shown, or the lawn might be where the children play. And I know from experience how it feels to inadvertently stand on a bee on a clover flower and the agony of being stung, not great for kids. Many people with large lawns are now leaving swathes unmown, even sowing wildflowers into it, but as Bathgate says, its personal preference, to which I'd add whatever's practical.

Oh I cannot deny that a fine turf lawn, neatly edged and mown in stripes is very attractive, (and hard work) and thought needs to be given if there are little bare feet running around. It is indeed a matter of personal preference. Personally I try to avoid chemicals and weedkillers for the environment, nature, wildlife and love the rewards nature gives back.
