In general you will use 2.3 - 4.6 lbs. per 1000 sq. ft. First you should determine which usage rate is needed for your use by reading the product label.
Here is how to determine what spreader setting is needed for your spreader:
If you need to use 3lbs of product per 1,000 sq ft you would add 3 lb of product to spreader, start with a medium setting, then apply product to a 20 x 50 ft area (1,000 sq ft). If you have product left, your setting is too low. If you run out of product, your setting is too high. Typically if you walk at a normal pace and set the spreader at the middle setting, that is usually the right amount per 1000 square feet.

You can also choose to do split applications in Spring as long as you do not reapply at the higher rate before 60 days, and you do not exceed the annual maximum rate of 600 lb per Acre, per the product label.
Roses are not specifically listed as plants that have been tested as tolerant of Snapshot 2.5 TG.

The Snapshot 2.5 DG is a brown color and comes in a 25lb bag. The application and active ingredients are both the same. They make the 2 different types due to some Turf Pros not wanting a yellow granule and prefer the brown granule.

Almost all fertilizers, herbicides, insecticides, etc have treatments in amounts of so much product per 1000 square feet. So if you can figure out what your walking speed is then you know anytime you apply any product that calls for so much of it per 1000 square feet, you always set your spreader on this setting. You can calibrate this by marking off a 1000 square foot (10 x 100) area and placing 4 ounces of any type of product of similar granule size, or of the Snapshot in the spreader. Start with a low setting and start walking your marked off area at a normal pace. You can adjust as you go and find the basic setting for you to apply the product over a 1000 square feet.
