You didn't say if this was a timed release fertilizer or not. I would think
that in your soil a timed release would be a good idea since nutrients wash
through so fast.
Whenever I redig a bed, I add Nutracote 13-13-13 270 day timed release. I like
Nutracote better than Osmacote because it has a more uniform release rate over
a broader temperature range than Osmacote. I think they are made by the same
company. The numbers aren't all that important as long as they are the same.
For instance, if you had a 20-20-20 you would just use proportionally less.
