I agree with RG, your efforts will hold strong if you have a lot of organic material in your soil. Now, if your soil is mostly dirt, you have a few options as far as organic fertilizers go.
You can use, alfalfa meal, blood meal, cottonseed meal, or fish emulsion for nitrogen.
Bone meal, I THINK, is good for phosphorous.
How much of each you should use depends on the time of year and the type of plant.
Since you have the vermicompost, I would suggest you make some [url=https://www.helpfulgardener.com/forum/viewtopic.php?t=17097&start=0]ACT[/url] with it.
Congratulations on a great start with your garden.
