We plan on using this product on our ash tree for ash borer. When is good time to apply?
You can apply the Safari 20SG Systemic Insecticide with Dinotefuran at any time as long as the ground is not frozen or when the plant is dormant. If you are already seeing activity then you can apply right away.
