You will use 1 fl. oz. of Bayer Advanced 12 Month Tree and Shrub Protect and Feed II - Concentrate for every inch of distance around the trunk of the tree. The amount of water that is used will vary depending on soil conditions and volumes that are easy for applicators to use. The minimum amount of water that should be used is 1 pint per foot of shrub height (or inch of trunk diameter for trees) but you may use 1 quart -1 gallon of water per foot of height (or inch of trunk diameter for trees) as well. Denser soils such as clay do not accept water as readily, so the lower volume of water is suggested. Since sandy soils can accept more water, using the higher volume of water is preferred. After the soil drench has been applied you should water it in with at east 1/2 inch of water.
