I have a lot of moss, buttercup and dandelion in my lawn and want to get rid of it. I also have
naturalised crocus. I gave the lawn its first cut recently (which decapitated the crocus) and am
now planning a chemical assault towards the end of May.

I need something that will kill the weeds but leave the near-dormant crocus alone.

What should I go for or avoid?

Have you considered lawn sand?
