When to Use Starter Fertilizer

Starter fertilizers are ideal during seeding, sod installation, and overseeding, as well as for use in gardens and ornamental plantings where early root development is critical.

worked where borax didn't

had hundreds of ants coming into our kitchen with little diminishment after several weeks of using borax-based bait. Added Advion bait gel, the ants like it too and in a week they were gone.
