can i apply liquid surflan to beds that have lillies or daffidills already 12 to 15 inches high?
Absolutely. As explained in our WEED CONTROL ARTICLE, one of the great features of SURFLAN is that it won’t hurt anything already growing. Use it at least twice a year to keep any weeds from growing locally in both your grass and flower beds.
