Fertilizer spike for fig tree in container ???

[pacifica]

Please help to advise if it is possible to use this fertilizer spike for various fig trees if planted :

1) In large container ? How many spikes should I apply ?
2) In ground ? How many spikes should I apply ?

Thanks...........

The spikes aren't a good way to fertilize. The fertilizer is too concentrated in one spot. They'd work better smashed into fine bits and spread across the surface or incorporated into the soil. That being the case just buy normal fertilizer and apply the same way.
