I have a Hibiscus tree and three bushes covered with armored scale. I want to do a soil drench and need to know how much Safari granules to mix in a gallon of water for a systemic application.
When doing a soil drench wtih Safari 20SG or any other systemic insecticide, the exact amount of water is not as important as using the correct amount of product. Your water is a carrier for the active ingredient, so you just need to use a sufficient volume of water to mix and apply the insecticide. To treat shrubs, you would use 3 to 6 grams (1.25 - 2.5 level teaspoons) of Safari 20SG per foot of shrub height, using 1-4 pints of water per foot of shrub height or per inch of trunk diameter for trees.
