This is somewhat outdoors related. I never used to have dandelions in my yard, but the past two years I have had an epidemic of them. They blow across the street from Sleepy Hollow park. I can't control the dandelions in the park, but I need them to stop overtaking my yard. I have had it professionally sprayed last spring and it reduced the numbers but didn't exterminate and now this year they are back worse than ever. I even put down weed killer and fertilizer on the lawn right after the snow melt. Someone please offer me a product that will kill these pesky buggers. Thanks in advance!
