It's a little scary that people read what I post. I just till it into my garden. In a garden it is 1/2 to 1 pound for ever 50 sq feet.
For a potted plant I would use a small amount (probably half a teaspoon) and mix it into the soil if I were repotting. If I weren't repotting, I'd just mix it into the water. It is a slow release fertilizer. It takes 30-60 days to release into the soil.
