Granular fertilizer dosing for potted plants

AMamani
by AMamani
I bought 20-20-20 granular fertilizer recently. It was sold by the kilo out of a large bag, so I didn't realize until I got home I didn't have any dosage instructions. I intend to use it for the potted plants on my patio (cherry tomatoes, roses, a few small trees, etc). Can anyone give me dosage estimates? I'm sure that it depends somewhat on each particular brand of fertilizer, but if I have a few examples maybe I can get close enough to do some good without burning the roots up!
