Conclusion

The best fertilizer for Boston ferns is a slow-release fertilizer that is high in nitrogen. Boston ferns are heavy feeders and will benefit from being fertilized on a regular basis. A slow-release fertilizer will provide a steady supply of nutrients to the plant and will not burn the roots.
