Can I weed n feed my lawn before coring?

We recommend completing lawn maintenance prior to the application of any chemical product, including Yates Weed 'n' Feed. By coring, this will better allow water and nutrients to penetrate the soil profile, which means the product will also be able to access the plants' roots and work more effectively. Ensure the lawn is well watered leading up to the application of the product and that it is not applied on days where shade temperatures are expected to exceed 30degrees.
