Jobe's Fertiliser Spikes are specially designed to feed all varieties of ferns and palms where they need it most, at the roots. Unlike other types of fertilisers, Jobe's Spikes are pre-measured, giving your plants just the right dosage of nutrients so you won't overfeed or burn them. And, by feeding underground, away from the soil surface, Jobe's slow release formula prevents waste and chemical runoff.
