Living plants give many natural benefits that we all absolutely need in our indoor environments. But why do they require so much care, water, fertilizer and so on? The reason is that indoor plants are natural islands, but living in unnatural backgrounds, not in their natural environments: since their space is confined to pots or limited flower beds, the soil where they live will never be able to create and to give the natural equilibrium it has in Nature and it will quickly lose the good features it originally had.
