Retep from Worcester, Ma writes
How late in the spring (Massachusetts) can it be applied to be effective?
Surflan Pro can last anywhere between 2 to 8 months depending on the dilution rates. Please refer to the product label for complete information and instructions. Depending on your area, pre-emergent applications are done in the spring and fall. We have some great information on the site under Cool Season Lawn Care Schedule.
