    We are relatively new in the landscape business. The subs we are using for chemical applications are licensed.
    The situation I have is on one of job sites. The customer signed on late and we missed the opportunity to apply pre-emergent chemicals. Now I have this area that they are trying to grow ground cover flowers on that is full of dandylions. I would appreciate any suggestions on attacking this problem. I have discussed it with my chemical man, who does not seem to have the answers. I want to kill the weeds not the flowers.

    I don't think you'll find anything that will kill dandelions and not groundcover.

    Selective round up applications are the only thing I know of. This would entail spraying just the dandylions or using a sponge applicator. If its a big area you will have your work cut out for you. There is always hand pulling.

    Spray it all and start over

    I would agree with Weedhead. Plateau can be used on wild flowers and will knock out certain weeds and grasses. What kind of flower are they?

    Lontrel can be used over evergreen plants as a selective postemergence.
