What is the setting for the Ortho Dial N Spray?
I am trying to knock out ground ivy and wild onion in my Kentucky blue grass/fescue lawn in Vermont. After first attempt, the ground ivy rebounded and became worse. I think I used the wrong mix ratio (too weak) and just pissed it off.
Fertilome Weed Free Zone product label recommends mixing 0.75 - 1.5 fl. oz. per gallon of water. For Ground Ivy we would recommend using the highest rate of 1.5 oz. per gallon of water. If the product instructions say to use 1.5 ounces per gallon of water, then the Ortho Dial N Spray should be set to the 1.5 oz mark if available. Broadcast (entire areas) applications or follow-up applications should be done at a 2-6 week interval which is recommended for more mature Weeds, for dense infestations, and for adverse environmental conditions.
