Please tell me the dimensions of your garden and I will do the calculation for you.

Thanks for writing back.
You have 100 square feet and need .15 pounds of Nitrogen and .3 pounds of potassium.
A 5 pound back of NPK 3-0-6 would contain
3% Nitrogen=.15 pounds in the whole bag
6% Potassium=.3 pounds in the whole bag.
Thus 5 pounds of a slow release fertilizer NPK about 3-0-6 would be perfect but it does not have to hit the numbers exactly.
You could even divide it into half doses about a month apart.

Thank you for the information.
So should I plant and then add the fertilizer to the plants or add to the whole garden and till in?
Thank You

If you have not planted yet, sprinkle the fertilizer, lightly rake, lightly water.

I apologize for an error in my calculations.
You have 1000 square feet and need 1.5 pounds of Nitrogen and 3 pounds of potassium.
A 20 pound bag of NPK 10-0-10 would contain
2 pounds of Nitrogen =10% in the whole bag
2 pounds of Potassium =10% in the whole bag
Apply twice now and in August. Be sure the bag says something like sustained or slo release Nitrogen.
Again sorry about the error. I was leaveing town and a pile of questions came in. Best to you.
