Yvan, Jobe's plant spikes are firtilizer spikes that can be put into the substrate under a plant. I usually put a quarter of a spike under a large sword plant every 3-4 months. You can pick them up at pretty much any store that has a garden center. Try to get the fern kind - it has a much lower phosphorus (P) ratio than the other kinds - they won't give you an algae bloom.
