Osmocote on anthurium plants

I have several anthurium plants and various websites say to fertilize them with Osmocote. They say to cut the amount that is indicated on the package by 75%. I bought some Osmocote from Home Depot last week to use but I do not see anywhere on the container how much to use per potted plant. I have some of the plants in 8 inch pots and some in 10 inch pots. Would you please tell me how much I need to use per 8 in and 10 in pot under normal circumstances (if you tell me what you recommend normally I can cut the amount by the 75% as indicated by anthurium growers).

The usual dose is one teaspoon, so cut that to one fourth of a teaspoon—much like giving something just a dash of seasoning when cooking. The one advantage of Osmocote is that it is released very slowly to the soil, so overfeeding is rare. Because the product contains so many micronutrients as well as nitrogen, phosphorus, and potassium (these are the big three or NPK), you know your plants will get all the essentials for best growth. Keep growing, Marianne Binetti
