Most of the indoor plants it is of tropical origin and prefers bright and fresh environments. The ideal average temperature is around 18-20 ° C with good relative humidity. The potting soil must be slightly damp and never wet, always perfectly drained. However, even when these optimal conditions are met, there are factors that threaten the health of indoor plants.
The greatest danger to the indoor plants it comes from man, or rather from human errors in the treatment regime. Too much water and too much fertilizer are the most frequent mistakes, followed closely by little water and zero nourishment. Mistakes in care aside, the deadly threats come from parasitic attacks.
Among the animal parasites that attack most frequently the indoor plants there are aphids (or lice) that prefer shoots and buds. The danger also comes from the white flies (whiteflies) which preferably settle on the underside of the leaves: shaking the plant, the flies take off to land again immediately afterwards, making themselves practically invisible.
Even more fearsome are the cochineals (white, cottony, scudetto) and the red spider, difficult to spot with the naked eye. At the first events it is necessary to intervene with specific, organic products to limit the impacts and create a more humid atmosphere. All the parasites mentioned do not like water and with a little more humidity and foliar washing, many go away immediately (if the attack is not serious).

Against red spider mites, and also aphids, biological prevention based on nettle macerate is excellent: you can prepare it yourself or buy it ready-made.
On the parasitic fungi front, the most frequent threats to health of indoor plants they are the mal bianco (powdery mildew) which forms a whitish patina on the foliage and the gray mold. Unlike animal parasites, fungal parasites love humid environments and stagnant air. So you need a middle ground and have a biological antifungal ready for any eventuality.
Finally, there are hidden physiopathies, which like gross errors in treatment can compromise the health of indoor plants. The most frequent depend on the proximity to direct heat sources such as radiators and unsuitable soil. We must be careful of this latter situation especially when repotting.
