New lawn concerns

We leveled the lawn area, put fertiliser down and planted loads of grass seeds and lawn has come up very nicely. Very few of the really annoying weeds however loads of what looks like littlle clover plants growong in the grass and short of pulling them up one by one we are nto sure what to do to remove them permanently or at least cutting down on their growth drastically.
Does any one have any suggestions? Thanks.

 

You'll either have to wait until your lawn is well established and then you can use a selective weedkiller or you can take the little clover plants out by hand (using a lot of care not to disturb the new grass seedlings). It all depends on a) how big your lawn is and b) how many clover plants you have in amongst the new grass.
