Product Review; "Keep your indoor plants alive and healthy for much longer with these affordable fertilizing spikes. Just insert a few spikes (depending on size of plant) in the soil and waterings will carry nutrients down into the soil without any waste or risk of shock to the plant. Usable for more than just Houseplants, but Easy Gardener Inc makes a few types for specific plants - They always work great, and require almost no extra work or attention!"
